What occurs if two objects at different temperatures are in contact?

Chemistry
1 answer:
Marat540 [252]3 years ago
8 0

Answer:

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter to the colder object until equilibrium is reached and the bodies reach thermal equilibrium (i.e., they are at the same temperature). ... Heat is a form of energy, whereas temperature is not.

Your veterinarian is administering a sedative to your 50 pound dog. The sedative is mixed in saline solution. Unfortunately the
Olin [163]

Answer:

26.25 mL

Explanation:

This is a dilution problem. First, let us calculate the volume of final solution needed:

The dog weighs 50 pounds and the sedative is administered at 0/7 ml per pound. Hence:

50 x 0.7 = 35 mL

A total volume of 35 mL, 2.5% solution of the sedative will be needed.

But 10% solution is available. There needs to be a dilution with saline water, but what volume of the 10% solution would be diluted?

initial volume = ?

final volume = 35 mL

initial concentration = 10%

final concentration = 2.5%

Using dilution equation:

initial concentration x initial volume = final concentration x final volume

initial volume = \frac{final concentration*final volume}{initial concentration}

                     = 2.5 x 35/10 = 8.75 mL

Hence, 8.75 mL of the 10% pre-mixed sedative will be required.

But 35 mL is needed? The 8.75 mL is marked up to 35 mL with saline water.

35 - 8.75 = 26.25 mL

<em>Therefore, 26.25 mL of saline water will be added to 8.75 mL of the 10% pre-mixed sedative to give 2.5%, 35 mL needed for the dog.</em>

Convert 8.43 x 1024 atoms of carbon to moles of carbon.
Sindrei [870]

Answer: 14.0 moles of carbon.

Explanation: Using the Avogadro's number,

6.02 x 10^23 atoms -----> 1 mole of carbon .

8.43 x 10^24 atoms ----> 8.43 x 10^24/ 6.02 x 10^23 = 14.0moles of carbon.
