Answer: the new pressure will be 300mmHg

Explanation:

V1 = 30L.

V2 = 50L

P1 = 500mmHg

P2 =?

P1V1 = P2V2

30 x 500 = P2 x 50

P2 = (30 x 500) / 50

P2 = 300mmHg

Steve and Meg are doing an experiment where they need to make 37 grams of Fe2O3. How many grams of Fe would they need ?

Anna11 [10]

Answer:

25.9g

Explanation:

Molecular mass of Fe₂O₃ = (56 * 2) + (16 * 3)

= 112 + 48 = 160

Let's follow the unitary method now

In 160g Fe₂O₃ , there is 112 g Fe

In 1 g Fe₂O₃ , there is 112 / 160 g Fe

In 37 Fe₂O₃ , we need 112 * 37 / 160

= 25.9 g Fe

irinina [24]

Answer:

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

Sulphurdioxide

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

Incomplete combustion produce harmful gases.

Explanation:

Carbon reacts with atmospheric oxygen to form carbondioxide as well as sulphur dioxide.

The chemical equations are as follows.

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

Sulfur dioxide is very harmful to the environment to cause acid rains.

This harmful gas mix with rain water to form sulphuric acid.

The balanced chemical equation for the reaction that produces harmful environmental effects is as follows.

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

$SO_{3}(g) +H_{2}O(l) \rightarrow H_{2}SO_{4}(l)$

In the absence of proper amount of oxygen required for combustion, incomplete combustion will take place which will result in formation of more carbondioxide an other harmful gases.

irina [24]

Answer:

c. in a mixture of gases like air, the total pressure is the sum of the individual partial pressures of the gases in the mixture.

Explanation:

<em>Dalton law is also known as Dalton's law of partial pressure. It simply explains that the total pressure exerted by a mixture of gases in a container is the sum of the individual gas pressure (partial pressure) exerted by each of the gases.</em>

Hence, the correct option is C.
