Answer:
Option O = H₂O
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
In this balanced chemical equation we can see that water is the only compound that consist of two hydrogen atom and one oxygen atom. H : O
2 : 1 .
In case of KOH two hydroxyl and two potassium atom are present and ration is K:OH 1:1.
Answer:
The answer to this question would be:
2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.
The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.
