If a reaction occurs and there were 10 g of Ca
reacting with 20 grams of water, and 5 grams of H2
was produced, how much Ca(OH)2 was produced?
Show your work.
Ca + H2O - Ca(OH)2 + H2

Answers

Answer:

18.52g

Explanation:

(relative atomic masses: H = 1.01, O = 16.00, Ca = 40.08)

Equation (balanced):

Ca + 2H2O -> Ca(OH)2 +H2

First, calculate the number of moles of 10g calcium

No. of moles of Ca  = 10/40.08 = 0.25 mol

Then, calculate the  number of moles of 20g water

No of moles of H2O = 1.11 mol

According to the balanced equation, 1 mole of calcium reacts with 2 moles of H2O completely.  Therefore, H2O is in excess.

So, 1 mole of calcium reacts with water to form 1 mole of Ca(OH)2 (according to the mole ratio shown in the balanced equation)

Therefore, 0.25 mol of Ca(OH)2 is produced.

Mass of Ca(OH)2 produced = no. of moles x molar mass = 0.25 x (40.08 + 16 + 16 + 1.01 + 1.01) = 18.52g

Good luck!

1. Calculate the density of a liquid that has mass of 14.0g and volume of 18.0 cm? Will this liquid float on
top of water or will it sink? (Density of water is 1.0 g/mL)
I

Answers

formula for density of liquid = mass ÷ vol

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³ ( 5sf)

= 0.778 g/cm³ ( 3sf )

18.0 cm³ is the same as 18.0 ml

Therefore, the liquid will float on water as the water is denser than the liquid.

18.0 cm³ is equivalent to 18.0 ml, in light of the fact that water is denser than liquid, the liquid will float on it.

What is the density of a liquid?

Density is defined as d = M/V, where M stands for mass and V for volume. The unit of density that is most frequently used is grams per cubic centimeter.

The formula for liquid density is mass divided by volume.

= 14.0 g ÷ 18.0 cm³

= 0.77778 g/cm³

= 0.778 g/cm³

The same procedure used to determine a solid's density is used to determine a liquid's density. Calculate the fluid's mass, then its volume, then divide mass by volume.

To determine the fluid's mass, weigh the fluid in the container, pour it out, weigh the empty container, and then subtract the empty container's mass from the mass of the filled container.

Therefore, in light of the fact that water is denser than liquid, the liquid will float on it.

Bombardier beetles inject boiling hydrogen peroxide, or H2O2, into the victims. It then decomposes into hydrogen and oxygen gas. How many grams of oxygen can be produced if 0.128 grams of hydrogen peroxide are decomposed?

Answers

Answer:

0.12 g of O2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

H2O2 —> H2 + O2

Next, we shall determine the mass of H2O2 that decomposed and the mass of O2 produced from the balanced equation. This is illustrated below:

Molar mass of H2O2 = (2×1) + (16×2)

= 2 + 32

= 34 g/mol

Mass of H2O2 from the balanced equation = 1 × 34 = 34 g.

Molar mass of O2 = 16×2 = 32 g/mol

Mass of O2 from the balanced equation = 1 × 32 = 32 g

Summary:

From the balanced equation above,

34 g of H2O2 decomposed to produce 32 g of O2.

Finally, we shall determine the mass of O2 produced from the decomposition of 0.128 g of H2O2. This can be obtained as follow:

From the balanced equation above,

34 g of H2O2 decomposed to produce 32 g of O2.

Therefore, 0.128 g of H2O2 will decompose to produce = (0.128×32)/34 = 0.12 g of O2.

Therefore, 0.12 g of O2 was produced.

What happens when an X-ray is shot at an atom

Answers

Answer: X-ray fluorescence from atoms occurs when a high energy particle or X-ray knocks an electron free from the innermost energy level of an atom, creating an unstable atom.

Explanation:

Several interactions can happen when an atom is exposed to an X-ray, depending on the energy of the X-ray and the properties of the atom.

The most frequent interaction is referred to as the photoelectric effect, in which an X-ray photon collides with an atom's inner-shell electron to evict it from its orbit and ionize the atom. As a result, an ion and a free electron are created. Another potential interaction is Compton scattering, in which an outer-shell electron receives some of the energy from the X-ray photon and is expelled at a different angle with less energy as a result. Additionally, pair production, which results in the formation of an electron-positron pair, can happen at very high energies. In many applications, these interactions are crucial.

The way to identify an element is by looking at the number of protons the atom has.  Every element has its own atomic number.  This atom has 6 protons.  If you look at the periodic table, you can see that the atom with the atomic number of 6 is carbon.

As the atom has six protons in it's nucleus, the atom is a form of  element of carbon.

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

How many calories are required to convert 2 grams of ice at 0 degrees C to water vapor at 100 degrees C?

Answers

Answer:

360.8987 GRAM CALORIE OR 0.3608987 KILOCALORIE IS THE CALORIE REQUIRED TO CONVERT 2 GRAMS OF ICE AT 0 DEGREES C TO WATER VAPOUR AT 100 DEGREES C.

Explanation:

To convert 2 g of ice at 0 C to water vapor at 100 C:

First, the ice will be converted to water at 0 C

Then, water at 0 C to water vapor at 100 C

We must know that the latent heat of fusion for ice is 3.35*10^5 J/kg

the standard heat of enthalpy of water = 4200 J/kg

So therefore

Total heat to convert ice at 0 c to water vapor at 100 c is:

= M Lf + mc Q

= 2/ 1000 * 3.35 * 10^5 + 2/1000 * 4200 * (100 -0)

= 0.002 * 3.35 ^ 10^5 + 0.002 * 4200 * 100

= 0.0067 * 10 ^5 + 840

= 670 + 840

= 1510 J

The heat required to convert 2 g of ice at 0 c to water vapor at 100 C is 1510 J and to get the calorie value we divide the answer in joules by 4.184.

1510 joules = 360.8987 gram calories or 0.3608987 kilocalorie.

Amount calories are required to convert into vapor is 1,440 calories

Latent heat of water:

Given that;

Amount of ice = 2 grams

Latent heat of water = 540 calorie

Find:

Amount calories are required to convert into vapor

Computation;

Heat required to melt at 0°C to water at 0°C = 2 × 80

Heat required to melt at 0°C to water at 0°C = 160 calorie

Water from 0°C to 100°C = 2 × 100

Water from 0°C to 100°C = 200 calorie

Water from 100°C to 100°C vapor = 2 × 540

Water from 100°C to 100°C vapor = 1,080 calorie

Amount calories are required to convert into vapor = 160 + 200 + 1080

Amount calories are required to convert into vapor = 1,440 calories
