Answer:
The number of atoms in the outermost shell
Explanation:
For example, the electron shells in the alkali metals contain the following numbers of electrons:
Li: 2, 1
Na: 2, 8, 1
K: 2, 8, 8, 1
They all have one electron in their outermost shell, and they have similar chemical properties.
Answer:
A) True/True
Explanation:
Non spontaneous exothermic reactions <u>need to reach the activation energy to get started</u> (like all non spontaneous reactions), usually this energy is given in the form of heat. So you can say the second statement is True
The first one is also True, if you don't give some energy (heat) to a non spontaneous reaction it won't start. Never the less, <u>exothermic reaction's conversion of equilibrium is decreased when heat is addeed to the system. </u>

Answer:
I'm pretty sure it's Density
Explanation:
Density differences in water masses due to temperature and salinity variations which makes a process known as thermohaline circulation. These currents move water through the ocean taking nutrients, oxygen, and heat with them.

The yield of ammonia rises as reaction pressure is raised. The yield of ammonia in the reaction actually declines as reaction temperature rises.
<h3 /><h3>What is ammonia ?</h3>
Ammonia, the simplest pnictogen hydride and a stable binary hydride, is a colorless gas with a strong, pungent odor. It contributes considerably to the nutritional demands of terrestrial creatures by serving as a precursor to 45 percent of the world's food and fertilizers. Biologically, it is a common nitrogenous waste, especially among aquatic animals. About 70% of ammonia is used to create fertilizers, including urea and diammonium phosphate, in a variety of shapes and compositions. Additionally, pure ammonia is sprayed straight onto the ground.
