To understand reaction order and rate constants. For the general equation aA+bB→cC+dD, the rate law is expressed as follows: rate=

A 100-g piece of metal initially at T = 75C is submerged in 100 g of water initially at T = 25C. The specific heat capacity of iron is 0.45 J g-1 °C-1 and the specific heat capacity of water is 4.18 J g-1 °C-1.

Atoms of metallic elements can form ionic bonds, but they aren't very good at forming covalent bonds. why?

Define significant figure. Discuss the importance of using the proper number of significant figures in measurements and calculations.

What is the mass of 4.6 moles of helium gas?

In the process of ionization, what is the relationship between the second ionization energy and the third ionization energy?

What are examples of convection?

Find the mass of 1 mole of cuprous oxide, or cu2o. assume the atomic mass of copper is 64 and oxygen is 16.

Ice (H2O) melting at 273 K and 1 atm has = 6.01 kJ/mol and = 6.01 kJ/mol while water vaporizing under the same conditions has = 37.6 kJ/mol and = 40.7 kJ/mol. Why is there such a large difference between and, but not for and?
