Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1

Answer:
Hydrogen
Explanation:
First thing's first, we have to write out the balanced chemical equation for the reaction.
This is given as;
N2 + 3H2 --> 2NH3
From the stoichiometrey of the reaction;
Molar mass of N = 14
Molar mass of H = 1
(1 * (14 * 2)) = 28g of N2 reacts with (3 * (1 * 2)) = 6g of H2
This means that if there are equal mass of both Nitrogen and Hydrogen. We would run out of Hydrogen first. This means Hydrogen is our limiting reactant as it determines the amount of products that can be formed.
Answer:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
