10._NaBr+_CaF2 -> _NaF+_CaBr2

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

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
