Answer:

Option D. ZnCl₂ and H₂

Explanation:

From the question given above, the following equation was obtained:

2HCl + Zn —> ZnCl₂ + H₂

Products =?

In a chemical equation, reactants are located on the left side while products are located on the right side i.e

Reactants —> Products

Now, considering the equation from the question i.e

2HCl + Zn —> ZnCl₂ + H₂

The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.

Thus, option D gives the correct answer to the question.

The puppies have different colored noses because of reccesive and dominant genotypes.

Genotypes are represented by letters, capital being dominant and lowercase being recessive.

For example, lets say t = pink nose and T = black nose.

If the parents have black noses, then they will pass on T genotypes.

But, they also have hidden pink nose genotypes.

These hidden genotypes are passed on to the puppies, one of the puppies gets more black nose genotypes.

If a puppy gets tt, they will have a pink nose.

If they get TT, they will have a black nose

If they get Tt, they will also have a black nose.

Because the black nose is dominant, its more likley for the puppies to end up with a black nose.

How many moles of iron(III) hydroxide precipitate will form when 2.7 moles of aqueous sodium hydroxide reacts completely with ex
aalyn [17]

Answer:

0.9 mole of Fe(OH)3.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

Fe(NO3)3 + 3NaOH —> Fe(OH)3 + 3NaNO3

Now, we can determine the moles of iron (III) hydroxide formed from the reaction as follow:

From the balanced equation above,

3 moles of NaOH reacted to produce 1 mole of Fe(OH)3.

Therefore, 2.7 moles of NaOH will react to produce = 2.7/3 = 0.9 mole of Fe(OH)3.

Therefore, 0.9 mole of Fe(OH)3 is produced from the reaction.
