Answer:
Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
Explanation:
Answer:
C
Explanation:
They are stabil and full of valence electron.
OILRIG:
Oxidation is loss (of electrons)
Reduction is gain (of electrons)
so...
The first one is an oxidation half-equation as the Sn loses electrons;
The second one is a reduction half-equation as the Cl₂ gains electrons
Answer:
The answer is D- creation of atmospheric systems that provide oxygen while absorbing carbon dioxide
Explanation:
By using elimination of choice that answer seems the most accurate.
Answer:
0.0050 mL
Explanation:
First we <u>divide the final volume by 20</u>:
So if we add 0.005 mL of the original sample to 0.095 mL of sterile DI water, we're left with 0.1 mL of a 1:20 dilution.
Rounding up 0.005 mL to four decimal places, the answer thus is 0.0050 mL.
