For the skeletal chemical equation bf3(g) + nah(s) → b2h6(g) + naf(s) what is the coefficient of b2h6 in the balanced equation? (balance the equation with the smallest possible whole number coefficients.)

Coefficient of in the balanced equation is 1.

Explanation:

Chemical equation given is:

Clearly the equation is not balanced.

Step 1:

There are six hydrogens in the RHS.Hence we make number of hydrogens as 6 in LHS by writing 6NaH.

Step 2:

Now the number of Na in LHS becomes 6.To balance it,we write 6NaF in the RHS.

Step 3:

Now there are only 3 flourines in LHS.So we write 2BF3 to make the number of flourine atoms 6.

Final balanced equation:

Coefficient of B2H6 is 1.

3 hours because it is a decent distance.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
