In chemistry, neutralization is a chemical reaction in which an acid and a base react quantitatively with each other, and where the final Ph of the solution is neutral (7).
In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
Answer:
44 g/mol
Explanation:
It should be CO2 for carbon dioxide
CO2= 12+2(16)=44
The answer for the following question is answered below.
- <em><u>Therefore the new pressure of the gas is 1.76 atm.</u></em>
Explanation:
Given:
Initial pressure of the gas = 1.34 atm
Initial temperature of the gas = 273 K
final temperature of the gas = 312 K
To solve:
Final temperature of the gas
We know;
From the ideal gas equation
P × V = n × R × T
So;
from the above equation we can say that
<em>P ∝ T</em>
= constant
=
Where;
= initial pressure of a gas
= final pressure of a gas
= initial temperature of a gas
= final temperature of a gas
=
= 1.76 atm
<em><u>Therefore the new pressure of the gas is 1.76 atm.</u></em>
Glucose + Oxygen -> Carbon Dioxide + Water + ATP
Answer:
(i),(ii) and (iv)
Explanation:
Villi are finger-like outgrowths of the human intestine.
The main role of villi is to amplify surface area for rapid absorption of digested food. They have very tiny walls; the role of these walls is to pass digested nutrients through diffusion. These are directly connected to the blood vessels. Thus, the circulating blood can carry these nutrients away.
The correct answer is the first option.
