Fusion releases less energy than fission

fusion most commonly combines heavy isotopes of hydrogen into helium.

Explanation:

Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.

The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.

Nuclear fusion reactions in the core of stars powers the universe.
The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
Small nuclei are involved in nuclear fusion and not the large ones.
Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.

Look at this balanced chemical reaction: N2 + 3H2 2NH3

stepladder [879]

Answer: A mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.

Explanation:

Given: Volume = 450 L

Temperature = 450 K

Pressure = 300 atm

Using ideal gas equation, moles of nitrogen are calculated as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = tempertaure

Substitute values into the above formula as follows.

$PV = nRT\\300 atm \times 450 L = n \times 0.0821 L atm/mol K \times 450 K\\n = \frac{135000}{36.945}\\= 3654.08 mol$

According to the given equation, 1 mole of nitrogen forms 2 moles of ammonia. So, moles of ammonia formed by 3654.08 moles of nitrogen is as follows.

$2 \times 3654.08 mol\\= 7308.16 mol$

As moles is the mass of substance divided by its molar mass. So, mass of ammonia (molar mass = 17.03 g/mol) is as follows.

$Moles = \frac{mass}{molar mass}\\7308.16 = \frac{mass}{17.03 g/mol}\\mass = 124457.96 g$

Thus, we can conclude that a mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.

If one liquid has a higher volatility than another, and both liquids are at the same

Romashka [77]

Answer:

Option B is correct

Explanation:

Step 1: Define volatility

In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.

At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.

The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,

Step 2: In this case:

⇒ Option A is false because the pressure will be higher when volatility is higher.

⇒ Option B is correct because higher volatility means evaporating more quickly

⇒ Option C is false because higher volatility means higher pressure. When pressure increases, the surface tension decreases.

⇒ Option D is false because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
