8. The density of an iron nail is the same as the density of an iron frying pan. Explain

1 answer:

6 0

A pure iron frying pan will have the same density as a pure iron anything under the same conditions, however pure iron is rarely used to make things. As their is carbon and traces of various metals, so the density will typically be slightly different, you can lower the density of the item with slightly higher density by heating it but leaving the lower density item cooler. Density is property of material that is independent of shape, volume, size and mass.

How much water should be added to 85 mL of 0.45 M HCI to reduce the concentration to 0.20 M?

valkas [14]

Answer:

106.25 mL

Explanation:

For this, we can use

C1×V1=C2×V2

C1 = 0.45

V1 = 85

C2= 0.20

V2= ?

0.45 × 85 = 0.20 × V2

V2= (0.45 × 85)/0.20

V2=191.25mL

To find the amount of water added, subtract V1 from V2

191.25 - 85 =106.25mL

0.68 moles of calcium to calcium atoms

Oksanka [162]

$0.68 \: moles \: calcium \times \frac{6.02 \times {10}^{23} \: calcium \: atoms }{1 \: mole \: calcium} \\$

The (( mole calcium ))s are simplified so the answer is based on the number of calcium atoms.

$0.68 \times 6.02 \times {10}^{23} = 68 \times {10}^{ - 2} \times 602 \times {10}^{ - 2} \times {10}^{23} \\$

$= 68 \times 602 \times {10}^{ - 4} \times {10}^{23} = 40936 \times {10}^{19} \\$

$calcium \: atoms = 40936 \times {10}^{19} \\$

Explain why the production of a gas in this experiment is or is not different from the formation of water vapor in the heating c

den301095 [7]

The production of a gas is different because unlike the heating curve, there was no heat applied to this experiment, and the experiment was a chemical reaction.

<h3>What is a Heating curve?</h3>

This shows the relationship between the temperature of the heating system and the air temperature in the outer environment.

The chemical reaction emitted heat as against the other which involved heat application which is why water formation in this curve was different.
