Answer: 1.1 moles H2O
Explanation: It looks like the equation is already balanced for you, so the first step will be to convert 144.1 grams of HNO3 to moles. To do this find the molar mass, and use to to do your conversion.Using the numbers provided for mass, this is the equation:1(1.0) + 1(14) + 3(16) = 1 + 14 + 48 = 63 g/mol144.1 g HNO3 x 1 mol HNO3 = 2.287 mol HNO3 63 g HNO3Now that you know how many moles of HNO3 you're starting with, use the ratio of moles in the equation to find the moles of H2O produced. The coefficient of HNO3 is 8, and H2O is 42.287 mol HNO3 x 4 mol H2O = 1.144 mol H2O 8 mol HNO3
The answer is: It expands when it freezes.
When molecule frezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.
For example, ice expands when water is freezing.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
Answer: the answer is B

Hydrogen Peroxide slowly decomposing into water and oxygen increases the entropy of the universe. Any reaction of a system always increases the degree of the orderliness of the universe. Decomposition is one of the best examples of increasing the entropy. This is when substance is broken down further to elements or other compounds.
