Answer:
Yes
Explanation:
The genetic testing is also called as the DNA testing. It is mainly used for identifying the changes in the DNA sequence or the chromosomes structure. It can also measure the results in the genetic changes.
Couples those who are planning to start a family should go for a genetic testing so as to minimize a risk in the upbringing or growth of their offspring. By doing a genetic testing a couple can well know the conditions of the baby that could affect them. The result from a genetic testing can help to plan better before starting a family. Therefore, it is advisable for couples to go for a genetic testing so that they plan better by knowing the conditions.
Answer:
1.52V
Explanation:
Oxidation half equation:
2Al(s)−→2Al^3+(aq) + 6e
Reduction half equation
3Sn2^+(aq) + 6e−→3Sn(s)
E°cell= E°cathode - E°anode
E°cathode= −0.140 V
E°anode= −1.66 V
E°cell=-0.140-(-1.66)
E°cell= 1.52V
D. Sometimes it is necessary to put forth new theories to explain experimental results,
Explanation:
Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.
Theories are explanation of scientific observations.
- Most scientists are critical and creative thinkers.
- They must be able to come up with a wide range of possible explanation to explain their findings.
- The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
- Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

Answer:
<u>Potential energy is</u> the stored energy in an object or thing, while <u>kinetic energy is</u> the energy which an object contains because of a particular motion.
Explanation:
<span>Answer: 0.00649M
The question is incomplete,
</span>
<span>You are told that the first ionization of the sulfuric acid is complete and the second ionization of the sulfuric acid has a constant Ka₂ = 0.012
</span>
<span>
With that you can solve the question following these steps"
</span>
<span>1) First ionization:
</span>
<span>
H₂SO₄(aq) --> H⁺ (aq) + HSO₄⁻ (aq)
Under the fully ionization assumption the concentration of HSO4- is the same of the acid = 0.01 M
2) Second ionization
</span>
<span>HSO₄⁻ (aq) ⇄ H⁺ + SO₄²⁻ with a Ka₂ = 0.012
</span>
<span>Do the mass balance:
</span>
<span><span> HSO₄⁻ (aq) H⁺ SO₄²⁻</span>
</span>
<span /><span /><span> 0.01 M - x x x
</span><span>Ka₂ = [H⁺] [SO₄²⁻] / [HSO₄⁻]</span>
<span /><span>
=> Ka₂ = (x²) / (0.01 - x) = 0.012
</span><span />
<span>3) Solve the equation:
</span><span>x² = 0.012(0.01 - x) = 0.00012 - 0.012x</span>
<span /><span>
x² + 0.012x - 0.0012 = 0
</span><span />
<span>Using the quadratic formula: x = 0.00649
</span><span />
<span>So, the requested concentratioN is [SO₄²⁻] = 0.00649M</span>
