Answer:
The stomach
Explanation:
In the stomach, physical digestion occurs because of peristaltic contractions (wave like contraction in the lean muscle) and chemical digestion occurs because of stomach acid, hydrochloric acid, breaking down your food.

Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
Answer: Hydrogen and oxygen make up water, which is a covalent compound. ... Phosphorus trichloride is used in the production of chemicals that keep plants from ... to Laura, the compound with the chemical name phosphorus trichloride has one atom of ... symbol P and three chlorine atoms represented by the chemical symbol Cl.
Explanation:
<span>Ideal Gas Law is as follows:
PV = nRT
Now lets rearrange so we can get rid of some variables.
V/n = RT/P
Assuming temperature and pressure are the same (atmospheric pressure), we can get:
PV/n = constant (k)
Now since we are dealing with an initial state (2.3 moles, 1.4 liters) lets set that as
V1 and n1 and the final state as V2 and n2
.V1/n1 = constant (k)
V2/n2 = constant (k)
Because the constant is the same (remember me making the assumptions above??)
V1/n1 = V2/n2
now rearrangement:
n1/V1/V2 = 1/n2 -1 = n2
Answer: 11.8 moles are in the final vessel. So to answer the question how much was ADDED, we need to subtract the initial mole number.
11.8 - 2.3 mols = 9.5 mols added</span>
