Answer:
2.44 K IS THE TEMPERATURE OF THE GAS
Explanation:
PV = nRT
P = 0.5 atm
V = 2 L
n = 5 moles
R = 0.082 L atm mol^-1 K^-1
T = ?
Substituting for T in the equation, we obtain:
T = P V / nR
T = 0.5 * 2 / 5 * 0.082
T = 1 / 0.41
T = 2.44 K
The temperature of the gas is 2.44 K
The answer for this question would be B) False or the second option.
Answer is FALSE: ✅
<u>Explanation:</u>
<u>1. Have many moons:</u>
- Jupiter is the fifth planet from the Sun and the biggest in the Solar System and it has fifty-three moons which are confirmed and twenty-six provisional moons and totally it has seventy-nine moons and it is the only planet which has many moons.
<u>2. Have a rocky composition:</u>
- The planets which have rocky composition are also called the terrestrial planets.
- The planets which have rocky composition are listed below mercury, venus, earth, and mars and they are smaller in size.
<u>3. Revolve quickly around the Sun: </u>
- Mercury is the quickest planet, which rushes around the sun at 47.87 km/s. And it revolves around the sun quickly.
<u> 4. Rotate quickly on their axes: </u>
- The giant gas planets like Jupiter, Saturn, etc... spin more quickly on their axes than the other planets
Answer:
1st order
Explanation:
because magnesium has a coefficient of 1, it is first order
hydrochloric acid has a coefficient of 2, so it is second order
overall the reaction is third order (1+2)
Explanation:
The word equation for the burning of a candle is wax plus oxygen yields carbon dioxide and water. This is an exothermic reaction that produces both light and heat.
The fuel for a burning candle is the wax. There are many different types of wax with a corresponding number of chemical formulas, but they are all hydrocarbons. Hydrocarbons are molecules made from hydrogen and carbon.
Burning the wax pulls the hydrogen and carbon in the wax apart and recombines them with oxygen from the atmosphere. This is an oxidation reaction. The resulting carbon dioxide and water are gases that disperse in the air.
