Answer is: sodium (Na) and iodine (I₂).
<span>
First ionic bonds in this salt are separeted
because of heat:
</span>NaI(l) → Na⁺(l) + I⁻(l).
Reaction of reduction
at cathode(-): Na⁺(l) + e⁻ → Na(l) /×2.
2Na⁺(l) + 2e⁻ → 2Na(l).
Reaction of oxidation
at anode(+): 2I⁻(l) → I₂(l) + 2e⁻.
The anode is positive
and the cathode is negative.
Answer: It would be Proteins. So B
Hope this helps!!!
DNA makes RNA which makes Proteins
Answer:
the number of neutrons in an atom of the element is 10.
Explanation:
neutron: mass # -protons
neutron: 19 (18.9984 (rounded)) - 9
neutron: 19- 9 =10
whole number is equal to the number of protons.
Answer:
C. CO2 exists in relatively high concentrations.
Explanation:
From the available options:
A. CO2 molecules are highly symmetrical.
B. CO2 has a low molar mass.
C. CO2 exists in relatively high concentrations.
D. CO2 is formed in the combustion of fossil fuels.
<em>The focus on CO2 as far as global warming is concerned is not because It has a high global warming potential but because of its relatively high concentration in the atmosphere as a result of both natural and anthropological activities.</em>
The correct option is C.
Answer:
The new volume is 808L.
Explanation:
First, you need to set up your proportion, using Charles's law.
V1 V2
<u> </u> = <u> </u>
T1 T2
Then, substitute for the ones you already know.
625 L V2
<u> </u> = <u> </u>
273 K 353 K
Then, you need to cross multiply.
625 x 353 = 273 x V2
Then, solve for V2.
220625 = 273 x V2
220625 ÷ 273 = V2
808 = V2
The final volume is 808L.
