What is the name of this hydrocarbon?

2,3-dimethylpentane
3,4-dimethylbutane
3,4-diethylpentane
2,3-diethylbutane

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

hcl + naoh → h2o + nacl

explanation:

hcl + naoh → h2o + nacl   is the reaction that is correctly balanced.

however, pcl3 + h2 → ph3 +3hcl, 2ca+ 3cl2 → cacl3, and c5h12 + 5o2 → 5co2 + 6h2o are not correctly balanced.

explanation:

rutherford's experiment showed that the atom does not contain a uniform distribution of charge.
