Answer:
D. It is the sharing of electrons between atoms with an electronegativity difference below 1.7
Covalent bonds share electrons, whereas ionic bonds exchange electrons. Covalent bonds have an electronegativity of 0.0-1.7 (0.0-0.3 is a nonpolar covalent bond and 0.3-1.7 is a polar covalent bond). Ionic bonds are bonds that go beyond the electronegativity of 1.7 to 4.0 (1.7-4.0).
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: 1. The average atomic mass of chlorine is 35.453u
2. The average atomic mass of copper is 63.5 u
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
1. For chlorine:
2. For copper:
I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
The third beaker: since it has the most amount of salt and the same amount of water as all the other beakers . So it has the highest concentrated amount :)
