Yes, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample.
<h3>What is Average Kinetic Energy ?</h3>
The average kinetic energy of a gas molecule is defined as the product of half of the mass of each gas molecule and the square of the RMS speed.
The average kinetic energy equation is independent of Molar mass.
It's only a function of temperature.
So if they're at the same temperature they will have the same average kinetic energy.
Therefore, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample

Answer:
The temperature change was 10.04 °C.
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system. In this way, there is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case you know:
- c= 1
Replacing:
7,529 cal= 1 *750 g* ΔT
Solving you get:
ΔT=
ΔT= 10.04 °C
So, <u><em>the temperature change was 10.04 °C.</em></u>

Answer:
Oxygen and magnesium come together in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
