<span>the ionization constant, Ka, for and indicator, HIn, is 1.0x10^-8. The color of the unionized form is red and the color of the ionized form is yellow. What is the color of the indicator in a solution whose pH is 4.6? (Hint: the color of an indicator can be estimated by considering the ratio of [HIn]/[In]. If the ratio is equal to or greater than 10, the color will bet hat of the unionized form. If the ratio is equal to or smaller than 0.1, the color will be that of the ionized form.
</span><span>Ka=[H+][A-]/[HA]
substitute for pH and find the value of A-/HA.

</span><span>so it'd just be 1x10^-8 divided by 4.6</span>
H has a charge of +1, and O has a charge of -2. In this case, C in C7H12 would have a charge of -12/7 to balance it out. Meanwhile, C in CO2 would have a charge of +4. Since the charge of C went from negative to positive, this implies that C lost electrons, which is indicative of oxidation (and thus it was the reducing agent). Therefore, C7H12 was the reducing agent, while O2 was the oxidizing agent.
Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.
Hope it Helps. :)

The answer to #1 is A. The answer to number 4 is that identical twins are from one egg and fraternal twins are from two different eggs. I'm sorry I don't know the other ones.
