Hey there! Hello!

The best answer I can give to you is that it depends. It depends on the way that the volume is being increased and if it's being increased along with the mass.

Volume represents the amount of space a substance, object, etc. takes up. Density represents the amount mass found in a given measurement of volume. Taking these definitions into account, we can see that volume directly correlates with the measurement of density.

Think of two buckets, one with one gallon of a substance and the other with two gallons of a substance. Both samples of the substance will have the same density, since mass was being added in addition to volume. Take a look at the example:

Bucket 1:
Mass of Substance = 1kg
Volume of Substance = 3cm^3
Density of Substance= 1/3 kg/cm^3

Bucket 2:
Mass of Substance = 3kg
Volume of Substance = 6cm^3
Density of Substance= 3/6 kg/cm^3 = 1/3 kg/cm^3

If we simply add substance, the mass and volume will increase together at a fixed rate, meaning that the most simplified version of the density fraction will always be the same.

But there's another part to this. You can increase or decrease the temperature of a sample, making volume increase/decrease and the mass stay the same. When you evaporate water, it turns to steam, which takes up much more space than it did as water. But nothing has been created or destroyed, so the mass stays the same. This would make the density change along with the volume.

I hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)

This question is about iron three of the raw material added to a blast furnace used to extract iron from henatite are coke hemat

IrinaVladis [17]

Answer: The fourth material that is added to the blast furnace is HOT AIR which provides OXYGEN for used for combustion of carbon (Coke).

Explanation:

Iron is the second most abundant metal found in the earth's crust after aluminium. It is not found in the free metallic state but are extracted from rocks which are rich in iron that contains other materials. These are known are iron ores and the most common iron ores are haematite ( Fe2O3).

Iron can be extracted from its ore with the used of blast furnace. The materials used for extraction of iron includes:

--> Coke

--> haematite( iron ore)

--> limestone and

--> Hot air.

The iron ore is first roasted in air so that iron(III)oxide is produced. The iron(III)oxide is then mixed with coke and limestone and heated to a very high temperature. Hot air is introduced into it from the bottom of the furnace. The coke is oxidizes the the oxygen in the hot air blast to liberate carbondioxide.

In the following reaction, how many grams of ammonia (NH3) will react with 27.8 grams of nitric oxide (NO)? 4NH3 + 6NO → 5N2 + 6

Rzqust [24]

4NH₃ + 6NO → 5N₂ + 6H₂O

mol of NO = $\frac{mass of NO}{Molar Mass of NO}$

= $\frac{27.8 g}{30.01 g / mol}$

 = 0.93 mol

Based on the balance equation mole ratio of NH₃ : NO is 4 : 6
= 2 : 3

If mol of NO = 0.93 mol

then mol of NH₃ = $\frac{0.93 mol * 2}{3}$

= 0.62 mol

Mass of ammonia = mol × molar mass

= 0.62 mol × 17.03 g/mol

= 10.54 g

Therefore B is the best answer
