If the gasoline tank in a compact car holds 12.0 US gallons, what is its capacity in liters?
Answer:
45.4249414 or about 45.42 liters
Explanation:
We know the gas tank holds 12 gallons, but we want to find the capacity in liters.
There are 3.785411784 liters in one gallon. Therefore, to convert from gallons to liters, multiply the number of gallons by 3.785411784
liters = 3.785411784 * gallons
The gas tank holds 12 gallons. Plug 12 in.
liters = 3.785411784 * 12
liters = 45.4249414
Let's round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 2 in the tenth place.
liters ≈ 45.42
The capacity in liters is 45.4249414 or about 45.42

The Gateway Arch in St. Louis, MO is approximately 630 ft tall. How many U.S. half dollars would be in a stack of the same height? Each half dollar is 2.15 mm thick.
Answer:
To equal the height of the Gateway Arch in St. Louis, it would take 76810 half dollars.
Explanation:
If the Gateway Arch in St. Louis is 630 feet high, how many half dollars will it take to equal the height if each half dollar is 2.15mm thick?
First, we convert the ft to cm and the cm to mm.
- 1 ft = 30.48 cm
630 ft = 19202.4 cm
- 19202.4 cm = 192024 mm
Now, if a half dollar is 2.15 mm thick, how many half dollars would it take to equal the height of 192024 mm?
1 half dollar = 2.15 mm
X = 192024 mm
X = 192024 mm / 2.15 mm
X = 76810 half dollars.

3. An adult rhino is 1350 kilograms. What is its mass in micrograms? Please write your answer in correct Scientific Notation. Micrograms
Answer:
1.35×10¹² μg
Explanation:
Mass (Kg) = 1350 Kg
Mass (μg) =?
Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:
1 Kg = 1×10⁹ μg
Therefore,
1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg
1350 Kg = 1.35×10¹² μg
Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.
Answer:
To convert 1350 kilograms to micrograms, we need to multiply by a conversion factor that takes us from kilograms to micrograms.
1 kilogram = 1,000,000,000 micrograms (by definition)
So,
1350 kilograms = 1350 x 1,000,000,000 micrograms
= 1.35 x 10^12 micrograms (in scientific notation)
Therefore, the mass of an adult rhino is 1.35 x 10^12 micrograms.

Explain how the magnitudes of the solute-solute, solvent-solvent, and solute-solvent interactions compared in order to account for the solution formation process being endothermic or exothermic
Answer:
See explanation
Explanation:
Energy is absorbed by solute molecules as the solute-solute interactions are broken in order to make solute-solvent interactions as a solution is formed. The nature of solven-solvent interaction also determines the possibility of a solute-solvent interaction because like dissolves like. Polar substances can only dissolve in polar solvents and nonpolar substances only dissolve in nonpolar solvents.
Therefore, the solution formation process is exothermic if solute-solvent interaction is greater than solute-solute and solvent-solvent interaction.
Similarly, solution formation process is endothermic if the magnitude of solute-solvent interaction is less than the magnitudes of solute-solute and solvent-solvent interaction.

what does balancing the charges mean when writing an ionic formula
Answer:
Balancing the charges in compound's ionic formula means ensuring that the sum of the charges of the radicals making up the ions is zero that is altogether, there is no net charge of the radicals
Explanation:
The guide to writing an ionic formula is as follows;
The radical with the positive charged ion or cation, is written first and the number of the atom with the charge is written as a subscript followed by the radical with the negatively charged ion, is written and the number of the atom possessing the charge is written as a subscript
The sum charges of the of positive and negative ions must be zero such that must be no net charge of the ions.
What mass, in grams, of water would form if 4.8 grams of hydrogen reacted with 38.4 grams of oxygen?
Answer: 4.8 grams of hydrogen is 2.4 moles, and 38.4 grams of oxygen is 1.2 moles. This is exactly the Stoichiometry ratio of the reaction, therefore the two will both completely react giving rise to the same total mass of water.
A 0.380 kg sample of aluminum (with a specific heat of 910.0 J/(kg x K)) is heated to 378 K and then placed in 2.40 kg of water that is at 293 K. If the system is left to reach its equilibrium state, what will the equilibrium temperature be? Assume that no thermal energy is lost to the external environment. Use 4.186 J/(g x K) as the specific heat of water.
Answer:
The equilibrium temperature of the system is 276.494 Kelvin.
Explanation:
Let consider the system formed by the sample of aluminium and water as a control mass, in which the sample is cooled and water is heated until thermal equilibrium is reached. The energy process is represented by First Law of Thermodynamics:
[tex]Q_{water} -Q_{sample} = 0[/tex]
[tex]Q_{water} = Q_{sample}[/tex]
Where:
[tex]Q_{water}[/tex] - Heat received by water, measured in joules.
[tex]Q_{sample}[/tex] - Heat released by the sample of aluminium, measured in joules.
Given that no mass is evaporated, the previous expression is expanded to:
[tex]m_{w}\cdot c_{p,w}\cdot (T-T_{w}) = m_{s}\cdot c_{p,s}\cdot (T_{s}-T)[/tex]
Where:
[tex]m_{s}[/tex], [tex]m_{w}[/tex] - Mass of water and the sample of aluminium, measured in kilograms.
[tex]c_{p,s}[/tex], [tex]c_{p,w}[/tex] - Specific heats of the sample of aluminium and water, measured in joules per kilogram-Kelvin.
[tex]T_{s}[/tex], [tex]T_{w}[/tex] - Initial temperatures of the sample of aluminium and water, measured in Kelvin.
[tex]T[/tex] - Temperature which system reaches thermal equilibrium, measured in Kelvin.
The final temperature is now cleared:
[tex](m_{w}\cdot c_{p,w}+m_{s}\cdot c_{p,s})\cdot T = m_{s}\cdot c_{p,s}\cdot T_{s}+m_{w}\cdot c_{p,w}\cdot T_{w}[/tex]
[tex]T = \frac{m_{s}\cdot c_{p,s}\cdot T_{s}+m_{w}\cdot c_{p,w}\cdot T_{w}}{m_{w}\cdot c_{p,w}+m_{s}\cdot c_{p,s}}[/tex]
Given that [tex]m_{s} = 0.380\,kg[/tex], [tex]m_{w} = 2.40\,kg[/tex], [tex]c_{p,s} = 910\,\frac{J}{kg\cdot K}[/tex], [tex]c_{p,w} = 4186\,\frac{J}{kg\cdot K}[/tex], [tex]T_{s} = 378\,K[/tex] and [tex]T_{w} = 273\,K[/tex], the final temperature of the system is:
[tex]T = \frac{(0.380\,kg)\cdot \left(910\,\frac{J}{kg\cdot K} \right)\cdot (378\,K)+(2.40\,kg)\cdot \left(4186\,\frac{J}{kg\cdot K} \right)\cdot (273\,K)}{(2.40\,kg)\cdot \left(4186\,\frac{J}{kg\cdot K} \right)+(0.380\,kg)\cdot \left(910\,\frac{J}{kg\cdot K} \right)}[/tex]
[tex]T = 276.494\,K[/tex]
The equilibrium temperature of the system is 276.494 Kelvin.

What is the density of an object that has a mass of 6.82g and when placed in water displaces the volume from 1.67mL to 7.87mL? Record your answer to the hundreds place.
Answer:
1.10 g/mL
Explanation:
The amount of volume an object displaces is the amount of volume that object takes up.
7.87 - 1.67 = 6.2
The object has a volume of 6.2 mL.
You have the mass (6.82 g) and the volume (6.2 mL). Divide the two value to find the density.
(6.82 g)/(6.2 mL) = 1.10 g/mL
The density of the object is 1.10 g/mL.
20. What will be the concentration, in mol dm, of the resulting solution when 200 cm' of
0.200 mol dmhydrochloric acid, HCl(aq) are mixed with 300 cm of 0.100
mol dm HCl(aq)?
Answer:
0.140mol/dm^3.
Explanation:
200cm3 = 0.2dm^3.
0.2dm^3 * 0.200mol/dm^3 = 0.040mol
300cm^3 = 0.3dm^3
0.3dm^3 * 0.100mol/dm^3 = 0.030mol
The number of moles is 0.070mol of HCl (aq).
The volume of the solution is 0.5dm^3.
Hence the concentration is 0.140mol/dm^3.
The concentration is 0.140mol/dm³.
What is concentration?The concentration of solution is the amount of solute that are dissolved in solution.The concentration can be measured by dividing the weight of solute in grams to the volume of solution.200cm³ = 0.2dm³
0.2dm³ x 0.200mol/dm³= 0.040mol
300cm³ = 0.3dm³
0.3dm³ x 0.100mol/dm³ = 0.030mol
The number of moles is 0.070mol of HCl
The volume of the solution is 0.5dm³
Concentration = Number of moles/volume in dm³
= 0.070mol/0.5dm³
= 0.140mol/dm³
Hence, the concentration is 0.140mol/dm³

When two carbon atoms are joined by a double bond, how many electron pairs are shared between the two carbons
Answer:
Two (2) electron pairs
Explanation:
The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.
However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.

Answer: The concentration of reducing ends is too small to detect.
Explanation:
The reducing sugar can be defined as the sugar that is capable of acting as a reducing agent because it possesses an aldehyde group and a ketone group. Some polysaccharides are reducing sugars but all the monosaccharides are reducing sugars. The polysaccharide with reducing sugars do not give a positive test for reducing sugars because the concentration or amount of reducing ends is too small to detect.

Convert 3.99/gallon to dollars per liter
Explanation:
Gas prices in the U.S. are given by the gallon; to convert them to liters, you'll divide the price by the number of liters in a gallon, 3.78541. So if gas costs $3.50 per gallon, you have $3.50 ÷ 3.78541 = $0.92460 per liter, which would typically be rounded to $0.92 per liter.
