All you have to do is explain the relationship between years and inches. The most rain was in 2004 with 10 inches and the least was in 1998 with 4 inches. In recent years there has been more rain than in the past. For the analysis just summarize that.
<span>When a
substance is heated, its atoms gain
energy and begin to vibrate rapidly within the lattice
of the substance (the substance expands). As more heating continues, the atoms
gain even more energy and move more rapidly until they are able to overcome the
force of the bonds, that hold the atoms together
in the lattice, until the structure is disrupted. </span>
Answer:
The salt is barium chloride.
Explanation:
Moles of barium sulfate =
According to reaction, 1 mol of barium sulfate is produced from 1 mol of 
.
Then 0.0480 moles will be produced from:
of .
Mass of used = 10.00 g
Moles of =\frac{10.00 g}{\text{Molar mass}}[/tex]
Molar mass of = 208.33 g/mol
The nearest answer to our answer is 
.
The correct answer barium chloride with molar mass of 208.2 g/mol.
Answer:
Non-zero digits are always significant
Answer: A. To change the potential energy of the reactants.
Explanation:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.
