The atomic radius increases down a column (group) and decreases along a row
A. Plastic is a good insulator.
Explanation:
what you have to do is to multiply the given grams with the ratio of grams of that certain element in it's full compound in order to isolate the compound and get the element.
because the question did not specify how many grams of NO2 is formed, we can assume that the mass is neglegible, thus 1 mole was assigned to Nitrogen.
The presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.
<h3>What determine acidic and basic nature of a solution?</h3>
The use of the pH scale is one way of determining the acidic and basic nature of solution. If the pH of a solution is less than 7, it is considered as acidic and if the pH is 7, the solution is neutral.
While if the pH is greater than 7,the solution is basic so we can conclude that the presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.
