Nitrate ions 
and potassium ions 
.
<h3>Explanation</h3>
Potassium dichromate undergoes a double-decomposition reaction with barium nitrate to produce barium dichromate and potassium nitrate. The reaction is possible due to the low solubility of barium dichromate that precipitate out of the solution readily after its production.
Start with the balanced chemical equation for this process:
Rewrite the chemical equation as an ionic one; express all soluble salts- those with state symbol (aq)- as their constituting ions while leaving the insoluble (s) intact.
and 
are found on both sides of the equation by the same quantity. The two ions thus took no part in the net reaction and act as spectator ions.
Answer:
A. ionizing energy increases
Answer:
The ways that mutation can affect an organism include:
Changing the physical characteristics of the organism.
It can impact the way that the DNA is able to code the genetic information.
Also, mutation can lead to the death of an organism.
What is mutation?
Mutation simply means a change in the DNA sequence of an organism. It can result from DNA copying mistakes that were made during the cell division.
Mutation can affect an organism as it changes the phenotype of the organism. It can also impact the way that the DNA is able to code the genetic information and lead to the death of an organism.
Answer:
.562 mol (with respect to signifigant figures)
Explanation:
to find moles we must use concentration to cancel liters.
2.250 mol/L x .250 L = .5625 mol
Answer:
1.D) CH4 + 2O2 → CO2 + 2H2O
2C)2,1,2
3.D)SIO2 + 4HF → SIF4 + 2H2O
4.D)2As + 6NaOH → 2Na3AsO3 + 3H2
5.C)SiCI4 + 2H2O → SiO2 + 4HCI
Explanation:
equal number of atoms of each elements in both the sides of the chemical equation is required to have an equation in balanced state.
