Waterways or lakes. at least that’s what google said lol.
Answer:
K
Explanation:
Potassium is a Period 4 Representative element, and is actually the first element of period 4.
The answer is (2) 12mL. The reaction equation is NaOH + HCl = NaCl + H2O. So the mol number of NaOH is equal to HCl. The concentration of NaOH is twice of HCl so the volume of HCl is twice of NaOH.
Answer:
2
Explanation:
Since you are balancing the equation you need to have equal amounts of each element on each side. Right now there is 2n and 2o on one side, and on the other 2n and 1o. Although the number of n's on each side is equal the number of o's are not. First I balance the number of oxygen's on each below, but doing that made the number of nitrogen's unbalanced. So then I balanced the nitrogens in step 2.
__N2+ __O2 = __N2O
1. __N2+ __O2 = 2 N20
2. 2 N2 + 1 O2 = 2 N2O
The difference lays in the position of the -OH groups bonded to the 3rd and 4th carbons in the molecules.
Explanation:
You may find in the attached picture the chemical structure of opened D-glucose and D-galactose.
You may see from the structure that D-glucose have the -OH group bonded to the 3rd carbon on the left side of the molecule while the D-galactose have the the -OH groups bonded to the 3rd carbon and the 4th carbon to the left side of the molecule.
