Answer:

D)

Explanation:

The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft. This causes the plates to move. The movement of these plates is known as plate tectonics.

Plates at our plantes surface move because of the intense heat in the earth core that causes molten rock in the mantle layers to move. It moves in a pattern called a convection cell that forms when warm material rises, cools and eventually sink down. As the cooled materials sink down, it is warmed and rises again.

Can a combination reaction be a redox reaction ?
saul85 [17]

Answer:

Yes A redox reaction can be a combination reaction.

Two elements are mixed in a combination reaction to produce a single product.

Explanation:

Example: water formula

2H2 + O2 → 2H2O

Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.

2H2 + O2 → 2H2O

80 liters of oxygen is collected over water at 50.0 degrees Celsius. The atmospheric pressure during the collection was 96.00 kp
vlabodo [156]

Answer:

The value of partial pressure of oxygen P_{O_{2} } = 83.66 K pa

Explanation:

Volume of oxygen = 80 liters

Temperature = 50°c

The total pressure = 96 K pa

The partial pressure of water at 50°c is calculated from the tables.

P_{H_{2}O } = 12.344 K pa

The total pressure is given by

P_{total} = P_{H_{2}O } + P_{O_{2} }

Put all the values in the above equation we get

96 = 12.344 + P_{O_{2} }

P_{O_{2} } = 96 - 12.344

P_{O_{2} } = 83.66 K pa

This is the value of partial pressure of oxygen.
