Please help me it’s due tmrw 1. In this section, you read about firefighters cleaning
up a hazardous spill of a base. This is the chemical
reaction they used:
H3PO4 + 3 KOH → K3PO4 + 3 H2O

(a) What type of reaction is this?

(b) Write the general equation for this kind of
reaction. Compare the equation above with the
general equation.

(c) Name the reactants

D) Name the products

a. double replacement

b. AB + CD ⇒ AD +CB

c and d

H₃PO₄ : Phosphoric acid

KOH : Potassium hydroxide

K₃PO₄ : Tripotassium phosphate

H₂O : water

Given

Reaction

H₃PO₄ + 3 KOH → K₃PO₄ + 3 H₂O

Required

Type of reaction

General equation

Name of reactants and product

Solution

Double replacement reaction : Cations and anions of different compounds switch places

It can also be said as a neutralization reaction because it produces water(reaction between an acid and a base)

AB + CD ⇒ AD +CB

H₃PO₄ : Phosphoric acid

KOH : Potassium hydroxide

K₃PO₄ : Tripotassium phosphate

H₂O : water

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
