A temperature change in a reaction indicates a “( physical change)”
Answer:
its true hope this helped :)
3% = 0.3
.03*540 = 16.2
540-16.2 = 523.8
Meaning 16.2 milliliters alcohol and 523.8 milliliters water. If my math is correct.
Answer:
As it is possible to observe in the drawing of the resonance structure of nitromethane, both oxygen atoms have the same negative charge.
Explanation:
A resonance structure is the molecular bonding system in which a hybrid, called a resonance, is formed from two or more Lewis structures that have different electronic distributions.
The resonance effect is given by the delocalization of electrons, which are not at a fixed point but are distributed homogeneously in the molecule as we can see in the nitromethane, providing stability. So the more resonance structures the molecule has, the more stable it will be.
Answer:
A. Neopentane.
B. 2,2-dimethyl-propane.
Explanation:
Hello,
In this case, for the given compound we can spell out two possible names:
A. Neopentane: it is, because the molecule has five carbon atoms wherein there is a central one, bonded to the other four.
B. 2,2-dimethyl-propane: it is, because we find two methyl radicals at the second carbon.
Regards.
