I believe this would be Ba3P2 (the numbers are subscripts; meant to be little)
I am taking Honors Chem so I hope this helps!!

How much energy is required to boil 65 grams of 100°C water<br> And then heat the steam to 150°C?

Artyom0805 [142]

Answer:

13598 J

Explanation:

Q = m × c × ∆T

Where;

Q = amount of energy (J)

m = mass (grams)

c = specific heat capacity

∆T = change in temperature

m = 65g, specific heat capacity of water = 4.184J/g°C, initial temperature= 100°C, final temperature = 150°C

Q = 65 × 4.184 × (150 - 100)

Q = 271.96 × 50

Q = 13598 J

Hence, 13598 J of energy is required to boil 65 grams of 100°C water and then heat the steam to 150°C.

Carbon dioxide gas is collected at 27.0(degrees)C in an evacuated flask with a measured volume of 30.0L. When all the gas has be

White raven [17]

Answer:

Moles of carbon dioxide gas is 0.584 moles.

Mass of 0.584 moles of carbon dioxide gas is 25.7 g

Explanation:

Using ideal gas equation

PV = nRT

where,

P = Pressure of gas = $0.480 atm$

V = Volume of gas = 30.0 L

n = number of moles of gas = ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 27°C = 300.15 K

Putting values in above equation, we get:

$(0.480 atm)\times 30.0 L=n\times (0.0821L.atm/mol.K)\times 300.15K\\\\n=0.5844 mol\approx 0.584$

Moles of carbon dioxide gas = 0.584 moles

Mass of 0.584 moles of carbon dioxide gas = 0.584 mol × 44 g/mol = 25.69 g ≈ 25.7 g
