Answer:
1. DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
2. both
Explanation: Since errors can occur when DNA replicates itself, mutations can occur in both asexually and sexually reproducing organisms.
Answer:
k = 4,92x10⁻³
Explanation:
For the reaction:
AB₂C (g) ⇄ B₂(g) + AC(g)
The equilibrium constant, k is defined as:
![k = \frac{[B_{2}][AC]}{[AB_2C]}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B%5BB_%7B2%7D%5D%5BAC%5D%7D%7B%5BAB_2C%5D%7D)
<em>(1)</em>
Molar concentration of the species are:
[AB₂C]: 0,0840mol / 5L = <em>0,0168M</em>
[B₂]: 0,0350mol / 5L = <em>0,0070M</em>
[AC]: 0,0590mol / 5L = <em>0,0118M</em>
Replacing this values in (1):
![k = \frac{[0,0070][0,0118]}{[0,0168]}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B%5B0%2C0070%5D%5B0%2C0118%5D%7D%7B%5B0%2C0168%5D%7D)
<em>k = 4,92x10⁻³</em>

An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions.
<h3>What is the difference between ionic equation and net ionic equation?</h3>
- A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.
- A molecular formula has two or more atoms bonded together, whereas a chemical formula can only refer to one atom. They are both elements, and their chemical symbols are unchanged.
- An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions. It is similar to a molecular equation in that it expresses compounds as molecules.
3FeSO4(aq) + 2K3PO4(aq) = Fe3(PO4)2(s) + 3K2SO4(aq)
ionic equation : 3Fe(2+)(aq) + 3SO4(2-)(aq)+ 6Na(+)(aq) + 2PO4 (3-) (aq) → Fe3(PO4)2(s)+ 6Na(+) + 3SO4(2-)(aq)
net ionic equation: 3Fe(2+)(aq) + 2PO4 (3-)(aq) → Fe3(PO4)2(s)
K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s)
net ionic equation for K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s).
2HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2
ionic equation : CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O()
