Answer:
N=+2
O=-2
Explanation:
The compound NO is electrically neutral.
Lets assign the oxidation number of nitrogen to be N. The oxidation number of oxygen (-2) is then used as a reference.
For the compound to have a zero charge, sum of the oxidation numbers equals zero.
N+ (-2)=0
N=+2
O=-2
<span>The glycine molecules can bind together and release a molecule of water by the process of condensation. Water would then be considered a by-product of the reaction. Condensation can also be seen when water in the air touches a container filled with cold liquid and you see water drops on the side of the glass.</span>
Answer:
1 M
Explanation:
The molarity of a solution, M, is a measure of the concentration of that solution and it refers to the number of moles of solute (mol) per liter (L) of solution. The molarity (M) can be calculated using the formula:
M = number of moles (n) /volume (V)
In this question, a 500 ml aqueous solution of Na3PO4 was prepared using 82g of the solute.
Molar mass of Na3PO4 = 23(3) + 15 + 16(4)
= 69 + 31 + 64
= 164g/mol
Mole = mass/molar mass
mole = 82/164
mole = 0.5 mol
Volume in Litres (L) = 500 ml ÷ 1000 = 0.500L
Therefore, Molarity (M) = 0.5/0.500
Molarity = 1 M or 1 mol/L
Compound= many parts together therefore bike is the answer
B. He would be considered an Organic Chemist since Organic Chemistry is the study of Carbon and its compounds.
