8Which Of The Following Statements Is FALSE About The Diagrams Above?Diagram B Is A Mixture Of Compounds.Diagram

Answers

Answer 1

Answer:

Diagram B is a mixture of compounds

Explanation:

The false statement about any of the diagram is that diagram B is a mixture of compounds.

Diagram is not a mixture of compounds. It is a single compound in gaseous state .

A compound is a combination of elements in a definite grouping. The properties of the compound is distinct from that of the element that combines to form it. Therefore, since we just a black and yellow circle, the diagram is a compound and nothing more. The other descriptions are perfect.

What is the balanced equation for KOH+CO2—>K2CO3+H2O

Answers

The balanced equation :

2KOH+CO₂⇒K₂CO₃+H₂O

Further explanation

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

KOH+CO₂⇒K₂CO₃+H₂O

give coeffiecient

aKOH+bCO₂⇒K₂CO₃+cH₂O

make equation

K, left=a, right=2⇒a=2

H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1

O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1

the equation becomes :

2KOH+CO₂⇒K₂CO₃+H₂O
