Answer:
112
Step-by-step explanation:
Since 7 goes into 7 put it down and subtract it’s 0
drop down 8 and only 7 goes into it (now you have 11 at the moment)
you have 1 remaining, drop down the 9, 7 goes in 15 twice, (so it’s 112)
with remainder of 5
What are the expressions?
Answer:
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:
2Na 2Na
2Br 2F
1Ca 1Ca
2F 2Br
This is balanced.
Step-by-step explanation:
2,1,2,1.
In a balanced chemical equation, the number of particular atoms on the right side of the equation is equal to the number of that atom on the left side of the equation.
As in the left side of the equation, there are 2 F atom and 1 Br. While on the right side there are 1 F and 2 Br. S for the balancing, we will put coefficient to the equation.
And the equation will be:
2NaBr + CaF2 → 2NaF + CaBr2
