Answer:
what you are putting on the concrete and how thick the concrete is.
Explanation:
If you want to but a house on a slab of concrete for a base, you will probably need a little more than you would for a sidewalk. If it is thicker, you will be able to hold more on it than you would if you spread it out thinly.
Answer:
![H_2(g)+O_2(g)\rightarrow H_2O_2(g)](https://tex.z-dn.net/?f=H_2%28g%29%2BO_2%28g%29%5Crightarrow%20H_2O_2%28g%29)
Explanation:
Hello!
In this case, since the formation reaction of a compound is undergone when the pure elements composing it are combined, for gaseous hydrogen peroxide, gaseous diatomic hydrogen and oxygen (standard state) must be combined in order to obtain the gaseous hydrogen peroxide as shown below:
![H_2(g)+O_2(g)\rightarrow H_2O_2(g)](https://tex.z-dn.net/?f=H_2%28g%29%2BO_2%28g%29%5Crightarrow%20H_2O_2%28g%29)
Whereas it is proved there are two hydrogen and oxygen atoms at each side of the chemical equation and therefore it is balanced.
Best regards!

In order to find density, you need to divide mass/volume

Let us study about this reaction </h2>
Explanation:
This given reaction is a chemical reaction that is : Double decomposition reaction .
In this reaction , there is a reaction between two compounds in which they mutually interchange their ions .
That is :
AB +CD ---> AC +BD
Similarly in this we have :
Na3PO4+KOH—->NaOH + K3PO4
The double decomposition reaction is either :
Precipitation reaction : resulst in the formation of ppt .
Neutralization reaction : results in the formation of neutral substance
