Answer:
Ba(NO2)2
Explanation:
Anything that contains calcium comes from a strong acid. Nitrous oxide (NO2) is a weak acid, therefore the salt it makes is less acidic than the rest --> the highest pH :)
Answer: The answer is D
Explanation:
So there is 2K + 2H2O --> 2KOH + 1H2
2Potassium + 2Water ---> 2Potassium Hydroxide + 1Dihyrogen
Answer:
See picture for answer
Explanation:
At the beggining, we know that X is a secondary alcohol, with 3 carbons. The only secondary alcohol with 3 carbons, it's the isopropylic alcohol (or 2-propanol). So, in strong acid conditions, we are actually dehidrating the alcohol, to form an alkene, and then it's oxidized to form either a Ketone or aldehyde.
So in picture 1, you have all three compounds, and the mechanism of reaction to form Y.
<span>When a chemist mixes oxygen gas and hydrogen gas to form
water, which is composed of one oxygen and two hydrogen atoms per molecule. The hydrogen and oxygen atoms bounds together by making a bond called covalent bond.<span> In a covalent bond, two atoms are bound
together because they each want to "share" each other's electrons.</span></span>
Answer:
all of these are properties of metalloids
