<span>The correct formula for Beryllium phosphate is Be3(PO4)2
Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6
-6 + +6 = 0</span>
Answer : The energy released is -3319.7 KJ.
Solution : Given,
Mass of methane = 59.7 g
Molar mass of methane = 16 g/mole
The value of is in negative that means the energy is releasing.
First we have to calculate the moles of methane.
Moles of methane =
Now we have to calculate the amount of energy released.
The given reaction is,
From the reaction, we conclude that
1 mole of methane releases -890 KJ/mole of energy
3.73 moles of methane releases of energy
Therefore, the energy released is -3319.7 KJ.

Answer:
Explanation:
Hello.
In this case, considering that 1 atm equals 1.01 kPa, we can compute the pressure in kPa first as shown below:
Now, we convert kPa to Pa, considering 1 kPa equals 1000 Pa:
Now, since Pa is equal to N/m², and 1 m equals 100 cm, the pressure in newton per square centimeter turns out:
Best regards.
