Answer:
A
Explanation:
They both need to lose 2 electrons to form ions
Answer:
2 tall 2 short.
Explanation:
If 1 is tall, and 1 is short, 50% would be tall, and the other 50% would be short.
I think it’s because from earth things may appear smaller smaller in space where in actuality in space it can be way larger
To solve this we assume
that the gas is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant temperature and number of moles of the gas
the product of PV is equal to some constant. At another set of condition of
temperature, the constant is still the same. Calculations are as follows:
P1V1 =P2V2
P2 = P1 x V1 / V2
P2 = 2.0 x 1.5 / 3
<span>P2 = 1 atm</span>
Answer:
The correct answer is B) HOOCCH2CH2COOH(aq)
Explanation:
Both Ka1 and Ka2 are low, so the acid will dissociate only slightly into HOOCCH2CH2COO- ions and even more slightly into -OOCCH2CH2COO- ions. The concentration of hydronium ions (H₃O⁺) will be consequently low. The species that will be in the highest concentration will be HOOCCH2CH2COOH (the weak acid not dissociated).
