Which are the followings and where is the data graphed i need a picture in order to help you
Answer: 1. 199.995 g of NaOH & 2. 2.014 g of H2
Explanation:
1. 5.00 mol H2O x __2 mol NaOH__ x __39.999 g__
2 mol H2O 1 mol
= 199.995 g of NaOH
2. 36 g H2O x __1 mol __ x __1 mol H2__ x __2.016 g__
18.016 g 2 mol H2O 1 mol H2
= 2.014 g of H2
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>
Answer:
Instead, pour a small amount into a beaker or clean weigh dish. Once you have added a chemical to a container, label it promptly. When you are finished with the experiment, dispose of the excess chemical as chemical waste. Do not simply pour the excess chemical down the sink.
