The list of elements that contains only metals is <span>B. tin, copper, cesium.
</span>In A, carbon and iodine aren't metals.
In C, helium isn't metal.
In D, neither iodine, carbon, nor argon are metals.
Answer:
15.98 L
Explanation:
First, you need to find T1, T2, V1 and V2.
T1 = 25 C = 298.15 K (25C + 273.15K)
T2 = 100 C = 373.15 K (100C + 273.15K)
V1 = 20. L
V2 = ? (we are trying to find)
Next, rearrange to fit the formula
V2 = V1 x T1 / T2
Next, fill in with our numbers
V2 = 20. L x 298.15 K / 373.15 K
Do the math and you should get...
15.98 L

Answer:
1) Complete combustion have enough oxygen present to produce carbon dioxide while incomplete combustion doesn't have enough oxygen
2) Complete combustion formula is:<u> </u><u>fuel+( plenty) oxygen--->Carbon-dioxide+</u>
<u>water while incomplete combustion is = Fuel+oxygen--->carbon monoxide+ water.</u>

Hope it helps.
Answer:
C5H12 + 8O2 → 6H2O + 5CO2
Explanation:
Pentane + Oxygen --> Water + Carbon dioxide
C5H12 + O2 --> H2O + CO2
The balanced equation is given as;
C5H12 + 8O2 → 6H2O + 5CO2
The principle is the law of conservation of matter that states that matter cannot be created nor destroyed. Hence, the reactants pretty much recombine to form the products.
The number of atoms remains conserved.
