Explanation:
Factory wastes are usually acidic and they pose serious environmental challenges.
If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.
On land, the acid can enter into the soil and prevent plant growth.
Acid discharge can enter the groundwater system and render it unfit for use.
Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.

During a neutralization reaction phosphoric acid reacts with potassium hydroxide to produce potassium phosphate and water, the reaction occurs with a 64.9% yield.
A neutralization reaction is a chemical process in which an acid and a base combine to produce salt and water as the end products. In a neutralization process, a mixture of H+ ions and OH- ions results in the formation of water.
Potassium phosphate and water are created when potassium hydroxide and phosphoric acid combine. The reaction's balanced equation is as follows: K3PO4(aq) + 3H2O = 3KOH(aq) + H3PO4(aq) (l) If six moles of potassium hydroxide react, phosphoric acid is used in the reaction.

Answer:
4.2 x 10⁴ mL
Explanation:
Data Given:
Density (d) of air = 1.19 x 10⁻³g/mL
Mass of the air (m) = 50 g
Volume of the air (V) = ?
Solution:
Formula will be used
d = m/V
As we have to find volume so rearrange the above equation
V = m/d . . . . . . . . . . . (1)
Put values in above equation 1
V = 50 g / 1.19 x 10⁻³g/mL
V = 4.2 x 10⁴ mL
So,
volume of dry air = 4.2 x 10⁴ mL

Concept: Chemical Analysis
- You need to start by graphing the data and then analyzing it.
- We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.
- The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.
- *I have confidence you can graph that*
