A carrier molecule is, A role in transporting electrons through the electron transport chain carrier molecules are usually poetries bond to a non-protein group they can undergo oxidation and reduction
All of the following are examples of electric force except A. A Neuton pushing on another Neutron. Neutrons are subatomic particles that possess no electrical charge.
You'll need Avogadro's number for this. NH3 has 1 Nitrogen and 2 Hydrogen. You'll multiply the molar mass of each times Avogadro's number. So:
molar mass N x 6.022x10^23 x 1 Nitrogen= total A
Molar mass H x 6.022x10^23 x 2 Hydrogen= total B
Add total A+B = your answer
I don't have a calculator or periodic table but if you plug in the numbers you'll get your answer. Hope it helps.
Answer:
0.0251 M
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
HNO3 + KOH —> KNO3 + H2O
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 1
Next, the data obtained from the question. This include the following:
Volume of acid (Va) = 10.1mL
Molarity of acid (Ma) =..?
Volume of base (Vb) = 61.9 mL
Molarity of base (Mb) = 0.0041 M
Next, we shall determine the molarity of the acid, HNO3 as follow:
MaVa/MbVb = nA/nB
Ma x 10.1 / 0.0041 x 61.9 = 1
Cross multiply to express in linear form
Ma x 10.1 = 0.0041 x 61.9
Divide both side by 10.1
Ma = (0.0041 x 61.9) /10.1
Ma = 0.0251 M
Therefore, the molarity of HNO3 is 0.0251 M
Yes, you do need to include the way you did the chemical experiment on your chemistry lab report for your Chemistry BDC.
You always need to include everything so that if their was something wrong that you can go back and do it over again to figure out where you messed up at and so the teacher can see how you got the answer so that they don't think you cheated.
Good Luck : )
