B. The number of collisions with enough energy to react increases.
The increase in temperature increases the average kinetic energy, so more collisions have enough energy to overcome the activation energy barrier.
We can use the ideal gas law equation to find the number of moles;
PV = nRT
where P - pressure
V - volume - 56.2 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature
standard temperature is 273 K
and standard pressure - 101 325 Pa
we can rearrange the equation to find the number of moles
substituting the values in the equation
n = 2.51 mol
molar mass of Ar - 40 g/mol
mass of Ar in the sample - 2.51 mol x 40 g/mol = 100.4 g
Answer:
From Pressure Law
P1/T1 = P2/T2
Changing our temp to kelvin
T1 = 47 +273 = 320K
We're looking for T2
Making T2 the subject
T2 =P2 x T1 / P1
= 655 x 320/850
T2 = 246K
Answer:
B it is decomposition reaction
Explanation:
In decomposition reaction compound is broken into two or other elements
<h3><u>Answer;</u></h3>
- Fish respiring and releasing carbon dioxide into the water.
- Mixing occurring at the surface of the ocean with the atmosphere.
<h3><u>Explanation;</u></h3>
- <em><u>Ocean absorb carbon dioxide in a number of ways. Fish and other animals in the ocean take in oxygen and give off carbon dioxide into the water. Ocean plants respires using oxygen and release carbon dioxide into the water.</u></em>
- <em><u>Oceans also absorbs carbon dioxide from the atmosphere when the air meets water. Wind causes waves and turbulence, giving more opportunity for eater to absorb the carbon dioxide. </u></em>
