Answer:H2+Br2-->2HBr
Step-by-step explanation:
The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.
On the left you got 2xH and 2xBr.
This means you must have the same amount on the right.
2HBr =2xH + 2xBr
The width of the enlarged photo is 9 inches.
Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?
2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.
to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
To multiply two (numbers to powers) . . . If the bases are the same,
then just keep the same base and add the powers.
To solve this problem, you just need to be able to add ' 5 ' and ' -2 '.
The answer is 'x' to that power.
