<span>The answer to your question is letter A. study how cholesterol is broken down in the body. Biology is a study of life which deals with cells, organelles, and other essential parts of the body or organism. Chemistry is a study about chemicals and how it reacts to natural state. In studying about cholesterol in the body, the presence of biologist and chemists will study how the body reacts with the chemicals and substances that were stored in the cholesterol.</span>
Given which are missing in your question:
the flask is filled with 1.45 g of argon at 25 C°
So according to this formula (Partial pressure):
PV= nRT
first, we need n, and we can get by substitution by:
n = 1.45/mass weight of argon
= 1.45 / 39.948 = 0.0363 mol of Ar
we have R constant = 0.0821
and T in kelvin = 25 + 273 = 298
and V = 1 L
∴ P * 1 = 0.0363* 0.0821 * 298 = 0.888 atm
Answer:
There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.
Explanation:
option (B) is right
As is, the equation has:
Reactants:
2 K
2 O
2 H
Products:
1 K
1 O
1 H
So, we can add coefficients to balance the equation:
K2O + H2O = 2KOH
The coefficient means that there are 2 moles of KOH, and now the equation is balanced as there is 2 of everything on both sides.
An anion is a negatively charged particle.
