Juan is taking out a loan for $2,500 with an annual compound interest rate of 7% for 3 years Juan will not make any additional deposits or withdrawals how much interest will he have to pay at the end of the loan period.
Last option:
CO2 (g) + H2O (l) -> H2CO3 (aq)
In the brackets:
g = gas,
l = liquid,
s = solid,
aq = aqueous.
So,
CO2 (g) = carbon dioxide gas
H2O (l) = liquid water
H2CO3 (aq) = aqueous carbonic acid
Physical change I’m pretty sure
