Can someone balance this chemical equation for me please : )
Gnoma [55]

Answer:

2

Explanation:

Tried out 1, but couldn't get whole numbers on the right side then, so went up to 2, worked

all four numbrrs: 2, 7, 4, 6

The 7 for oxygen got adjusted in the last step of the thinking, because it's the simplest to adjust.

since there are different prime numbers (or rather numbers that don't share prime factors) in the set, the numbers can't be revived by the same number and still give whole numbers as results (they can't be smaller)

a gas that exerts a pressure of _____ bar in a container with a volume of 0.5650 L will exert a pressure of 715.1 bar when trans
vampirchik [111]
Boyle's law gives the relationship between pressure and volume of gases.
it states that for a fixed amount of gas at constant temperature, pressure of gas is inversely proportional to volume.
PV = k
where P - pressure , V - volume and k - constant 
P1V1 = P2V2 
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting this equation 
P x 0.5650 L = 715.1 bar x 1.204 L
P = 1 524 bar
