Answer:

See explanation

Explanation:

We know that 1 mole of a gas occupies 22.4 L

Hence, 1.65 moles of nitrogen gas occupies 1.65 moles * 22.4 L/1 mole = 36.96 L or 3.696 * 10^1 L = 3.70 * 10^1 L

The exponent of the scientific notation answer = 1

The right most significant figure in the answer = 2

Answer:

C

Explanation:

trees (as well as other plants) produce carbon dioxide. deforestation is the removal of trees. this will not cause an increase in any pollutants such as ozone. ozone is made from VOCs and other harmful pollutants, and not caused by trees. tearing down trees will also not create more soil. So the answer has to be C

Answer:

V = 15.6 L

Explanation:

Hello there!

In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:

[tex]M=n/V[/tex]

Thus, given the moles and concentration of the solution, we can find the volume as shown below:

V=n/M

Therefore, we plug in the given data to obtain:

V = 2.5mol /(0.16mol/L)

V = 15.6 L

Answer:

16.85mol

Explanation:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molecular mass. That is;

number of moles (n) = mass (m) /molar mass (MM)

Molar mass of lithium = 6.9g/mol

Hence,

number of moles = 116.3 ÷ 6.9

Moles = 16.85mol

Therefore, 16.85moles is present in 116.3g of Li.

Answer 4.45 moles

Explanation:

Answer:

the number of moles of the gas is 0.00174 mol.

Explanation:

Given;

temperature of the, T = 300 K

volume of the gas, V = 1.45 L

Pressure of the gas, P = 3.0 kPa

The number of moles of the gas is calculated using Ideal gas equation, as follows;

PV = nRT

Where;

n is number of moles of the gas

R is the ideal gas constant, = 8.315 L.kPa/mol.K

n = PV / RT

n = (3 x 1.45) / (8.315 x 300)

n = 0.00174 mol.

Therefore, the number of moles of the gas is 0.00174 mol.

Answer:

true.

Explanation:

Answer:

True

Explanation:

Answer:

When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.

Answer:

As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

Answer:

The sun's circumference is about 2,713,406 miles (4,366,813 km). It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars. Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter.

Answer:

691.6 mmHg

Explanation:

At standard temperature and pressure, temperature of a system = 273K, and pressure= 1atm

T1= 273.15K

P1= 1atm

T2= (–25°C +273.15 )= 248.15K

From Gay-Lussac's law which expressed that at constant volume, pressure of a particular mass of gas is directly proportional to temperature . It can be expressed as

P1 / T1 = P2 / T2

Where P1= initial pressure

T2= final temperature

T1= initial temperature

P2= final pressure

Making P2 subject of the formula

P2= (P1 × T2)/ P1

Substitute the values we have

P2= (1 atm × 248.15K)/273.15

P2= 0.91 atm

But

1atm= 760 mmHg

0.91 atm= X mmHg

If we cross multiply we have

X mmHg= (760× 0.91)/1

= 691.6 mmHg

Hence, the final pressure of the gas in mmHg is 691.6 mmHg

Answer:

the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons--- True

boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron......True

compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen...... false

the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state......false

Explanation:

The octet rule simply means that atoms tend to be stable when they have eight electrons in their outermost shell. This rule mostly applies to the s and p orbitals and not to the d and f orbitals. The sum of the total electrons in the outermost s and p orbitals is often equal to eight for an atom to be considered stable, for example, the noble gases.

Boron often forms compounds which has less than eight electrons around the boron central atom because the compounds of boron often have a sextet of electrons owing to the fact that boron is trivalent and forms mostly covalent compounds.

Nitrogen compounds mostly obey the octet rule and do not have excess electrons. The oxidation state of hydrogen in SiH4 is not unusual.

Questions

Explanation:

The word "science" was obtained from the Latin word "Scire" which means "to know". Hence science is a systematic investigation into the nature of the universe.

Scientific investigations begin with asking questions about the universe. It is this curiosity to know about occurrences in the universe as well as how to solve problems in the universe that leads to fascinating scientific investigations and discoveries.

Gibbs free energy predict spontaneity if G < 0, the reaction is spontaneous and the correct statement is option C.

Gibbs free energy is a quantity that is used to measure the maximum amount of work done in a thermodynamic system when the temperature and pressure are kept constant.

Gibbs free energy is denoted by the symbol ‘G’. Its value is usually expressed in Joules or Kilojoules.

Gibbs free energy can be defined as the maximum amount of work that can be extracted from a closed system.

Gibbs free energy to determine the spontaneity of a process.

Therefore, Gibbs free energy predict spontaneity if G < 0, the reaction is spontaneous and the correct statement is option C.
