Answer:
atoms bond to attain neutral configuration or to get noble gas configuration.
Explanation:
atoms always want to be stable by attaining noble gas configuration.
they do so by forming bonds. they also bond to each other to make their outer electrons stable that is if the atom has an excessive electron than its neutral configuration it can bond to another atom that has one less electron than its neutral configuration by ionic bond.
Answer: D
An equal number of atoms must be on both sides of the equation.
Because matter cannot be created nor destroyed.
The mass of the hydrogen is obtained as 0.302 g.
<h3>What is the mass of hydrogen?</h3>
A hydrocarbon is a compound that contains only carbon an hydrogen. The amount of the carbon and the hydrogen can be found by combustion.
The mass of hydrogen can be obtained as follows;
Number of moles of hydrogen =2.7 g/18 g/mol * 2 = 0.302 moles
Now the mass of hydrogen is obtained from;
0.302 moles * 1 g/mol = 0.302 g
