What is the valence number of HCO3-.​

Chemistry

-1 is the answer

So it requires one cation (i.e. positively charged ion). So according to this, its valency is -1. A hydrogen carbonate ion has the formula HCO3-, so the valency of a hydrogen carbonate ion is -1.

Cyclopropane is more reactive than most cycloalkanes. What factors lead to cyclopropane being less stable than the other cycloal
maw [93]

Answer: The factor that lead to cyclopropane being less stable than the other cycloalkanes is the presence of a RING STRAIN.

Explanation:

In organic chemistry, the end carbon atoms of an open aliphatic chain can join together to form a closed system or ring to form cycloalkanes. Such compounds are known as cyclic compounds. Examples include cyclopropane, cyclobutane, cyclopentane and many among others.

Cyclopropane is less stable than other cycloalkanes mentioned above because of the presence of ring strain in its structural arrangement. The ring strain is the spatial orientation of atoms of the cycloalkane compounds which tend to give off a very high and non favourable energy. The release of heat energy which is stored in the bonds and molecules cause the ring to be UNSTABLE and REACTIVE.

The presence of the ring strain affects mainly the structures and the conformational function of the smaller cycloalkanes. cyclopropane, which is the smallest cycloalkane than the rest mentioned above, contains only 3 carbons with a small ring.

madam [21]

When sulfur reacts with zinc metal is forms a compound known as zinc sulfide.

<h3>Name of the elements</h3>

The names of the elements that make up the compound will be determined from the atomic mass of the elements.

<h3>Which element has atomic number 30</h3>

The element that atomic number of 30 is zinc and it has oxidation number of +2.

<h3>Which element has atomic number 16</h3>

The element that atomic number of 16 is sulfur and it has oxidation number of -2.

<h3>Chemical reaction between sulfur and zinc metal</h3>

Zn²⁺ + S²⁻  --------> ZnS

Thus, when sulfur reacts with zinc metal is forms a compound known as zinc sulfide.

A student must make a 3 m acid solution using a 5 m acid solution. which of these is the safest way to make the solution?
weqwewe [10]
The motivation to abstain from adding water to concentrated acids is that, with a few acids, amid weakening, a considerable measure of warmth is discharged, by adding the corrosive to the water, the generally extensive measure of water will retain the warmth. On the off chance that you added water to concentrated corrosive when you initially beginning pouring the water, it could get sufficiently hot for the little measure of water that was filled all of a sudden bubble and splatter corrosive on you. Concentrated sulfuric corrosive is most famous for doing this, not all acids get that hot on weakening, but rather in the event that you make a propensity for continually adding the corrosive to water for every one of them, you can't turn out badly.
