As chlorine has seven electrons in its outer most shell so to complete its octet it has to gain an electron and when it gain an electron it will become an anion that is negatively charged
so in my opinion and what a conclude is that the option B is correct for the above statement
D because these are the biggest particles, and are therefore, the most dense.
In order to find the number of moles with a given mass of Helium, we need to use its molar mass, which is 4.0026g/mol, therefore we will have:
4.0026g = 1 mol of Helium
91.5g = x moles of Helium
x = 22.86 moles of Helium in 91.5 grams
The conclusion best supported by the data can either be high temperature, low temperature, and normal temperature. Since there are diverse substances included in the chart, It is expected to also have diverse temperatures.
When methane is burned with oxygen, the products are carbon dioxide and water. If you produce 9 grams of water and 11 grams of carbon dioxide from 16 grams of oxygen, how many grams of methane were needed for the reaction? First you need to write a balanced chemical equation.
