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
It's called a base.
Hope this helps!
The percent error is calculated by the formula Absolute Value of (Error - Actual / Actual then times 100).
In this case the Error value was 76, and the Actual was 80.
So, set up the expression
I(76 - 80)/80 x 100I
I-4/80 x 100I
I-400/80I
I-5I
5
The percent error was 5 percent, since that was how much her estimation differed from the actual amount.
<h2><u>5 percent</u></h2>
Answer:
The answer is A.
Step-by-step explanation:
1 plus 2x (276-5y) + 69= A.
Answer:

Step-by-step explanation:
Given equation:

<u>Step-1: Subtract 1/4 both sides</u>
