How do you calculate how much energy it takes to heat a certain amount of a certain material to a certain temperature? I have access to a latent heat table and specific heat constant table. Thanks for the help! Some examples:
1. Heat 2 kg ice from –5°C to 0°C
2. Melt 2 kg ice at 0°C
3. Heat 2 kg water from 0°C to 100°C

Ihat will happen if i added baking soda to vinegar

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?
