Wine goes bad soon after opening because the ethanol (CH3CH2OH) in it reacts with oxygen gas (O2) from the air to form water and acetic acid (CH3COOH), the main ingredient of vinegar. What mass of ethanol is consumed by the reaction of 9.1g of oxygen gas?

Round your answer to 2 significant digits.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
