8.) If 396 g of Carbon Dioxide (CO2) are produced, what mass of Oxygen

Chemistry
1 answer:
KengaRu [80]3 years ago
3 0

Answer:

480 g of oxygen.

Explanation:

C3H8 + 5O2 --->  3CO2 + 4H2O

Using the molar masses:

3*12 + 6*16 g of CO2 were formed from 10*16 g O2

132g  g CO2 from 160 g O2

1g CO2 from (160/132) g O2

396 g from (160/132) * 396

= 480 g of oxygen.

Determine the pH and pOH of a soft drink with a 0.001 M H ^ 4 and state If It acidic, basic, or neutral
Sonbull [250]

Answer:

pH= 3, 00 (acidic solution), pOH= 7,00

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = -log (H 30+)

pH= -log (0.001)

pH=3, 00  (the solution is acidic because the pH is less than 7,00)

We know that the sum of the pH and pOH is 14, so we solve pOH:

pH + pOH= 14

3, 00 + pOH=14

pOH= 14 - 3,00= 7, 00

Solids, liquids, and gases are the three most commonly accepted phases of matter. Explain the properties of each phase, includin
nasty-shy [4]

Answer:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another.  They have least kinetic energy.  For example : chair

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.  They have more kinetic energy than solids but less than that of gases. For example : oil

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.  They have most kinetic energy. For example : Hydrogen
