HCI+CaCO3=CaCl2+H2O+CO2​

Chemistry
1 answer:
Nookie1986 [14]4 years ago
5 0

Answer:

2 HCl + CaCO3  = CaCl2 + H2O + CO2

Explanation:

On the right side we have 2xCl, to get the same amount we will multiply HCl on the left side by 2.

This will give us 2xH on the left side; we also have 2xH on the right side ( in H2O).

On both sides we have 1x Ca; 1x C.

On the left side we have 3XO (in CaCO3), on the right side we have 1O in H20 and 2xO in CO2, so 3x O on the right side as well.

The reaction is balanced.

Pine trees slightly prefer slightly acidic soil. What happens if the pH changes to above 7?​
egoroff_w [7]

Answer:

The trees' growth might be affected

Explanation:

A pH above 7 indicates that the soil is no more acidic and that it had turned basic or alkaline in nature. This may affect the functioning of enzymes as this value is very far from optimum pH value. Thus growth is affected.

1. Determine whether or not the equation below is balanced. If it isn’t balanced, write the balanced form. Also, identify the re
strojnjashka [21]

Answer:

- Not balanced.

- Reactants: Zn  and HCI .

- Products: ZnCl₂ and  H₂.

- Substitution reaction.

Explanation:

Hello,

In this case, for the given reaction:

Zn  +  HCI  →  ZnCl₂ +  H₂

We can see that it is not balanced due to the fact that at the left side we have one hydrogen atom whereas at the right side two, taking into account the number must be same as well as chlorine. Thus, in order to balance we write:

Zn  +  2HCI  →  ZnCl₂ +  H₂

And that is enough. Moreover, we can see that the chemical species at the left side of the equation are the reactants and those at the right side the products, thus we have:

Reactants: Zn  and HCI .

Products: ZnCl₂ and  H₂.

Finally, since we can see that the chlorine is at the reactants with hydrogen, but at the end with the zinc, and the initial zinc is alone as well as the yielded hydrogen we can infer this is a substitution reaction.

Best regards.
