Answer:

Potential energy is stored energy meaning something is waiting to come out and when it does it will turn into kinetic energy.

Say you had a bow in arrow when you pull that back and are waiting to let it go that is potential energy and then when you do let it go it turns into kinetic.

Potential energy is electrical,chemical,nuclear and mechanical energy it is also gravitational energy.

You could also say potential energy is a object being held depending on it's position like when a roller coaster stops at the top ,that is potential energy and then when it goes down it again turns into kinetic.

Usually all the time potential energy will always turn into kinetic energy.

Hope this helps have a great day:)

A mixture of MgBr2 and inert material is analyzed to determine the Mg content. First the mixture is dissolved in water. Then all

Mumz [18]

Answer:

9.24% the percent of Mg in the mixture.

Explanation:

Mass of silver bromide = 1.1739 g

Moles of silver bromide = $\frac{1.1739 g}{188 g/mol}=0.006244 mol$

1 mole of AgBr has 1 mole of bromine atom.Then 0.006244 moles AgBr has 0.006244 mole bromine atom.

Moles of bromine atoms = 0.006244 moles

Magnesium bromide has 2 moles of bromine atom.Then 0.006244 moles of bromine atoms will be in :

$\frac{0.006244 mol}{2}=0.003122 mol$

Magnesium bromide has 1 mole magnesium atom, then 0.003122 moles of magnesium bromide will have :

$1\times 0.003122 mol=0.003122 mol$ magnesium atom

Mass of 0.003122 moles of magnesium :

0.003122 mol × 24 g/mol = 0.07493 g

Mass of the sample = 0.8107 g

Percentage of magnesium in the sample ;

$=\frac{0.07493 g}{0.8107 g}\times 100=9.24\%$

9.24% the percent of Mg in the mixture.
