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

actant(s) and product(s) in this equation. Finally, label this as one of the five types of reactions: combination, decomposition, substitution, double replacement, or reversible.

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.

Distinguish(solid,liquid,gas)​
amm1812

Answer:

Explanation:

A solid, at a given temperature, has a definite volume  

and shape which may be affected by changes in  

temperature. Solids usually increase slightly in size  

when heated (expansion)  and usually  

decrease in size if cooled (contraction).A liquid, at a given temperature, has a  

fixed volume and will take up the shape of any  

container into which it is poured. Like a solid, a  

liquid’s volume is slightly affected by changes in  

temperature.

A gas, at a given temperature, has neither a definite  

shape nor a definite volume. It will take up the shape  

of any container into which it is placed and will  

spread out evenly within it. Unlike those of solids  

and liquids, the volumes of gases are affected quite  

markedly by changes in temperature.

Define climate and weather. What is climate change? Why is it important to know about climate change?
olga55 [171]

Answer:

It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.

Weather is the state of the atmosphere at any given time and place.

Climate is the long-term average of the weather in a given place
