What is the pressure in a 5.00 L tank with<br> 7.10 moles of oxygen at 39.3 °C?

Katena32 [7]

Answer:

36.4 atm

Explanation:

To find the pressure, you need to use the Ideal Gas Law. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = constant (0.0821 L*atm/mol*K)

-----> T = temperature (K)

Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.

P = ? atm R = 0.0821 L*atm/mol*K

V = 5.00 L T = 393 °C + 273.15 = 312.45 K

n = 7.10 moles

PV = nRT

P(5.00 L) = (7.10 moles)(0.0821 L*atm/mol*K)(312.45 K)

P(5.00 L) = 182.130

P = 36.4 atm

Inside stars in space, the nuclei of hydrogen atoms fuse together to form helium atoms. This represents which form of energy?

mixas84 [53]

Explanation:

When two small nuclei combine together to form a large nuclei then it is known as nuclear fusion.

When nuclei of two hydrogen atoms fuse together then it results in the formation of a helium atom along with the release of lot of energy. This energy is nuclear energy.

This nuclear reaction is as follows.

$^{2}_{1}H + ^{3}_{1}H \rightarrow ^{4}_{2}He + ^{1}_{0}n + Energy$

Thus, we can conclude that nuclear fusion represents nuclear energy.
