Select the correct equalities for the units shown.
elena-14-01-66 [18.8K]

Answer

1. 1cm=10mm, 1kg=1000g and 12in=1 ft

2. 50mm=5cm

    48 in =4ft

     36ft=12 yd

     2.5m=250cm

     1000mL= 1 L

Explanation

if 1cm=10mm then 5cm=?

5×10=50mm

if 12 in =1ft then 48in=?

48/12 =4 ft

if 1m=100cm, then 2.5m=?

2.5×100= 250cm

and when know from capacity that 1000mL is equivalent to 1 liter.

aluminum bronze contains 92.0% of copper and 8.0% aluminum. what maximum mass of aluminum bronze can be prepared from 73.5g of c
slega [8]
The answer is 79.9 g.

Copper takes 92.0% of aluminum bronze and it is a limiting factor. We have aluminum in excess, so we need to make a proportion.
If 73.5 g of copper are 92.0%, how many g of aluminum bronze will be 100%:
73.5 g : 92.0% = x : 100%.
x = 73.5 g : 100% * 92.0%
x = 79.9 g

Therefore, from 73.5 g of copper and 6.4 g of aluminum (since 79.9 g - 73.5 g = 6.4 g), maximum 79.9 g of aluminum bronze can be prepared.

solubility of gas solutes in water as temperature increases such as CO2 or O2 gas and explain why using the collision theory.
ludmilkaskok [199]

Answer:

See explanation

Explanation:

When a substance is heated, its average kinetic energy increases as the molecules move faster owing to the supply of energy. The solvent molecules are able to collide more frequently with the solute molecules and dislodge them so that the solute can dissolve in the solvent.

However, when a gaseous solute is dissolved in a liquid; as the temperature is increased and solvent molecules are able to collide more frequently with the solute molecules and dislodge them, gas molecules dissolved in the liquid are more likely to escape to the gas phase and not return due to the increase in their kinetic energy.

Hence, solubility of gas solutes in water decreases as temperature increases.
