What are the benefits and drawbacks to having a pouring temperature that is much higher than the metal’s melting temperature?

Chemistry
1 answer:
Mashcka [7]3 years ago
3 0

Answer:

The main advantage would be that with the pouring temperature being much higher, there is very little chance that the metal will solidify in the mould while busy pouring. This will allow for moulds that are quite intricate to still be fully filled. The drawbacks, though, include an increased chance defects forming which relates to shrinkage (cold shots, shrinkage pores, etc). Another drawback includes entrained air being present, due to the viscosity of the metal being low because of the high pouring temperature.

How many moles of H2O are produced form 2.11 mole of oxygen?
aivan3 [116]

Answer:

4.22 mol H₂O

Explanation:

Step 1: Write the equation for the synthesis of water

2 H₂ + O₂ ⇒ 2 H₂O

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to H₂O is 1:2.

Step 3: Calculate the moles of water produced from 2.11 moles of oxygen

We will use the previously established molar ratio.

2.11 mol O₂ × 2 mol H₂O/1 mol O₂ = 4.22 mol H₂O

What would happen to the air pressure on Earth's surface if the density of Earth's atmosphere were to suddenly double?A. The air
Sladkaya [172]

Answer:

B. The air pressure would increase 2X

Explanation:

Pressure = density × acceleration due to gravity × height

p = ρ × g × h

Pressure is force per unit area

p = F/a

Density is mass per unit volume

Pressure is directly proportional to density hence, any change in the density of a body directly affects the change in pressure of the body and vice versa.
