25 g of Mg3(PO4)2 is about 0.096 mol so each mol of that is equal to 3 mols of Mg
which leads to about 6.9 g of Mg
Mg : 24 g/mol
P : 30 g/mol
O : 16 g/mol

The burning characteristics of a gasoline can be improved by converting the octane it contains into isooctane. This conversion r
bogdanovich [222]

Gasoline is refined petroleum used in engines as a fuel. It contains octane that can be converted to isooctane by adding catalysts like platinum and palladium.

<h3>What are catalysts?</h3>

Catalysts are substances that raise the reaction rate by decreasing the activation energy but do not get consumed themselves in a reaction.

Platinum and palladium metals can be used as a catalyst to convert the octane of the gasoline into isooctane as they are oxidation catalyst that converts the fuel components into water and carbon dioxide.

Therefore, platinum and palladium are used as catalysts in converting octane.

How many seconds are there in 23 days ?
Brrunno [24]
Since there are 23 days and 24 hours in each day, you multi-ply them and get 552 hours. Since each hours is 60 minutes, 552*60 is 33120 minutes. Since one minute is 60 seconds, 60*33120 is 1,987,200 seconds. Therefore, there are 1,987,200 seconds in 23 days.

You're at the zoo and have a big red 1.80 L helium balloon. The barometric pressure today is 785 mmHg. Then you hear the roar of
fomenos

Answer: The volume of the balloon up there is 6.192 L.

Explanation:

Given: V_{1} = 1.80 L,    P_{1} = 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm

P_{2} = 0.300 atm,       V_{2} = ?

Formula used to calculate volume is as follows.

P_{1}V_{1} = P_{2}V_{2}

Substitute the value into above formula as follows.

P_{1}V_{1} = P_{2}V_{2}\\1.032 atm \times 1.80 L = 0.300 atm \times V_{2}\\V_{2} = 6.192 L

Thus, we can conclude that the volume of the balloon up there is 6.192 L.
