To solve this you would divide until you can’t. I recommend staying in whole numbers:) I always divide by twos because I think it’s more efficient! 4 divided by 2 is 2 and 30 divided by 2 is 15 sooo (2 hours to 15) hope this helped!
Answer:
The completed reaction is
CaCO3 + 2 HCl → (Ca+2 + 2 Cl-)aq + H2O + CO2↑
You do 4/1 divided by 2/9
4 2
_ divided by _
1 9
Equals 18
(You have to multiply by the reciprocal)
4/1 times 1/4
And
2/9 times 1/4
Hope I helped!!!
There are 6 apples and 2 oranges.
So the ratio of apples to oranges would be 6:2.
However this can be simplified, because these number have a common factor, which is 2. So you divide 2 by 2, and 6 by 2, and get 1 and 3. So the ratio of apples to oranges in simplified form is 1:3. Hope this explains it :)
The answer would be 2.4, or in fraction form 12/5. Please mark brainliest <3
