<u>Answer:</u> The correct answer is Option E.
<u>Explanation:</u>
Atomic radius is defined as the total distance measured from the nucleus of an atom to the outermost shell.
<u>Trend down the group:</u>
Moving from top to bottom, a new shell gets add up around the nucleus and the outermost shell gets far away from the nucleus. Due to this, the distance between the nucleus and outermost shell increases, which results in the increase of atomic radii of the atom.
<u>Trend across the period:</u>
Moving from left to right in a period, more and more electrons gets add up in the same shell. The attraction between the last electron and the nucleus increases. This results in the shrinkage of size of an atom. Thus, decreasing the atomic radii of the atom.
Hence, the correct answer is Option E.
Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of 
= Total mass of 
As we are given :
Total mass of = 65.7 grams
So,
65.7 grams = Total mass of
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
False. For example, changing climates will mean that some areas that experience harsh weather will soon being to experience milder weather. :)
