Mass of the condensed unknown liquid: 0.3175 g Temperature of the water bath: 99.00 oC Pressure of the gas: 748.2 mmHg Volume of

lbvjy [14]

Answer:

1. 0.98 atm

Explanation:

The following data were obtained from the question:

Mass of unknown liquid (m) = 0.3175 g

Temperature (T) = 99 °C

Pressure (P) = 748.2 mmHg

Volume (V) = 145.0 mL

Gas constant (R) = 0.08206 atm.L/Kmol

1. Determination of the pressure in atm.

760 mmHg = 1 atm

Therefore,

748.2 mmHg = 748.2/760 = 0.98 atm

Therefore, the pressure in atm is 0.98 atm.

If the density of a metal bar is 3.47 g/mL and volume is 30 mL, calculate the mass of the metal bar in grams (g). Show the steps

Hitman42 [59]

Answer:

$m=104.1g$

Explanation:

Hello,

In this case, considering that the density is considered as the quotient of the mass and volume:

$\rho =\frac{m}{V}$

We can easily compute the mass by solving for it as follows:

$m=V*\rho =30 mL*3.47g/mL\\\\m=104.1g$

Best regards.

Answer:

The answer to your question is SO₂ + 3H₂ ⇒ H₂S + 2H₂O

Explanation:

Reaction

SO₂ + H₂ ⇒ H₂S + H₂O

Reactants Elements Products

1 Sulfur 1

2 Hydrogen 4

2 Oxygen 1

This reaction is unbalanced so we need to balance it.

SO₂ + 3H₂ ⇒ H₂S + 2H₂O

Reactants Elements Products

1 Sulfur 1

6 Hydrogen 6

2 Oxygen 2

Now, the reaction is balanced
