I’m BEGGING you PLEASE help me :(((

Chemistry
1 answer:
lisov135 [29]3 years ago
4 0

Answer:

C.

Explanation:

Since we are trying to find the amount of moles of oxygen, we use the balanced equation to help us out. Since there are 4 moles of Sb for every 3 moles of oxygen, we must use a conversion to let us get rid of the Sb unit and get our desired unit of moles of oxygen. Therefore, C is our best answer.

How many formula units are contained in 23.5 g of Sb2S3
wolverine [178]
The molar mass of Sb2S3 is approximately equal to 339.7 g/mol. We calculate the number of moles of Sb2S3 by dividing the given mass by the molar mass. 
                                     n = 23.5 g / (339.7 g/mol)
                                        n = 0.0692 mols
To calculate for the number of formula units, we multiply the number of mols by the Avogadro's number, 
                            number of formula units = (0.0692 mols)(6.022 x 10^3)
                                                   = 4.167 x 10^22 formula units

How much heat is required to raise the temperature of 81.0 g of water from its melting point to its boiling point?
Dovator [93]

Answer:

Specific heat of water = 33.89 KJ

Explanation:

Given:

mass of water = 81 gram

Initial temperature = 0°C

Final temperature = 100°C

Specific heat of water = 4.184

Find:

Required heat Q

Computation:

Q = Mass x Specific heat of water x (Final temperature - Initial temperature)

Q = (81)(4.184)(100-0)

Q = 33,890.4

Specific heat of water = 33.89 KJ
