Can some one me i can’t figure it out for the life of me

Balanced equation is displayed above

1. It is important to balance equations so that you know how many moles of reactants are required to make the moles of products. This will provide you with the correct stoichiometric ratios to work out the relationship between the reactants and products.

2. To balance equation you:

1. Leave Mg as it is as there is 1 Mg on each side of the equation

2. there is 2 F2 and 2 Li on the left side but oy one of each on the right so you write a 2 in front of the LiF

3. CO3 is balanced already

4. Chemical equation is balanced

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
