NeX [460]

Answer:

Fe2S3 + 4HCl —> 2H2S + 2FeCl2 + S

Explanation:

From the question, we were told that:

Iron(III) sulfide reacts with hydrochloric acid to produce hydrogen sulfide and iron(II) chloride.

Please note that elemental sulphur is produced along with this reaction. The equation for the reaction is given below:

Fe2S3 + HCl —> H2S + FeCl2 + S

Now, we can balance the equation as shown below:

There are 3 atoms of S on the left side of the equation and 2 atoms on the right. It can be balance by putting 2 in front of H2S as shown below:

Fe2S3 + HCl —> 2H2S + FeCl2 + S

Now, we have 4 atoms of H on the right side and 1atom on the left side. It can be balance by putting 4 in front of HCl as shown below:

Fe2S3 + 4HCl —> 2H2S + FeCl2 + S

Also, there are 4 atoms of Cl on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of FeCl2 as shown below:

Fe2S3 + 4HCl —> 2H2S + 2FeCl2 + S

Now, we can see that the equation is balanced

What should be the effect of losing ones sight on the ability to digest food

One mechanism is enzyme induction.

Enzymes are proteins, which are metabolically expensive to produce. It makes evolutionary sense that your body makes less digestive enzymes such as lactase and sucrase when they're not needed. If your diet changes, your body can gradually increase the production of some enzymes through a process of enzyme induction.

For example, the production of lactase enzyme can be increased in some lactose-intolerant individuals by feeding them lactose . Also, studies in rats have shown that other carbohydrate-digesti<span>Your body makes more of what it needs, and less of what it doesn't need--brilliant!</span>ng enzymes, such as sucrase-isomaltase, trehalase, and maltase-glucoamylase--can be induced by hydrocortisone administration.

You are asked to perform a reaction by dissolving hypochlorous acid in water. Based on your understanding of acids, you understa

AnnZ [28]

According to the principle of chemical equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium refers to the equilibrium which exists between chemical species in a reaction such that the rate of forward and backward reactions are the same.

Since the reaction is in equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase ad equilibriumwill shift to the right of the reaction.

a person measures the mass of an 8 cm3 block of brown sugar to be 12.9 g. What is the density of the brown sugar.

Maksim231197 [3]

From the information we have, this block of brown sugar has a volume of 8cm3

The mass of the block is 12. 9 grams.

We need to find out the density of the sugar.

For a solid material the formula for calculating density is given as:

Density = mass / volume

Therefore we simply fit in the above given values into this formula, so:

Density = 12.9 / 8

Density = 1.61

Therefore the density of the block of sugar is 1.61g/ml
