Answer: There are
atoms present in 0.500 mol of
.
Explanation:
According to the mole concept, there are
atoms present in 1 mole of a substance.
In a molecule of
there is only one carbon atom present. Therefore, number of carbon atoms present in 0.500 mol of
are as follows.

Thus, we can conclude that there are
atoms present in 0.500 mol of
.
Answer:CO2(g) will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time
Explanation:
Answer:
C. An external voltage source
Explanation:
An electrolytic cell converts electrical energy from an external voltage source into chemical energy that drives a reaction.
The external voltage source is usually a battery. This energy form generated from the battery helps to drive chemical reactions.
The process involves the decomposition of an ionic compound by means of current passed into the aqueous or molten form of the compound through conductors known as electrodes.
As it is located at 7s ^2 it will have 2 valence electrons that due to its position in the s orbital it will be prone to losing them to obtain a noble gas configuration.
