1. your skin is full of nerves. The skin feels the cold temperature which tells the nerves it is cold. the nerves then send signals to target muscle to start shivering. the rapid movement of the muscles then create heat, which keeps your body temperature where it should be.
2. if a person has high blood glucose levels, that means the body has too much sugar. This could mean that the pancreas is not producing enough insulin, which is a hormone that helps your body use the sugar for energy.

Answer:
148.2 g of H20
Explanation:
Equation of reaction: 4NH3 + 5O2 ---> 4NO + 6H20
From the equation above, 4 moles of ammonia reacts with 5 moles of oxygen gas to produce 6 moles water.
Molar mass of NH3 = 17 g/mol;
Molar mass of O2= 32 g/mol;
Molar mass of H2O = 18 g/mol
First, we determine the limiting reactant:
4*17 g of NH3 reacts with 5*32 g of O2
Mass Ratio = 68 : 160
Therefore, NH3 is the limiting reactant.
68 g of NH3 reacts to produce 6* 18 g of H20 = 108 g of H2O
93.3 g of NH3 will react to produce (93.3 * 108)/68 g of H20 = 148.2 g of H2O
Therefore, the maximum amount of H2O produced = 148.2 g
