Catalysts help in increasing rates of reactions
Answer:
Average atomic mass = 24.3051 amu
Explanation:
Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......
For 24 Mg
Mass = 23.985 amu
Fractional Abundance = 0.7899
Mass * Fractional Abundance = 18.9458
For 25 Mg
Mass = 24.986 amu
Fractional Abundance = 0.10
Mass * Fractional Abundance = 2.4986
For 26 Mg
Mass = 25.983
Fractional Abundance = 0.1101
Mass * Fractional Abundance = 2.8607
Average atomic mass = 24 Mg + 25 Mg + 26 Mg
Average atomic mass = 18.9458 + 2.4986 + 2.8607
Average atomic mass = 24.3051 amu
Answer:
Nothing
Explanation:
Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!
