Describe the smell of Na+ and H+
KIM [24]

Answer:

Sodium ion ( Na+) is known to have no smell at all but however appears salty which is the reason why the compound Sodium Chloride has the same type of taste.

Hydrogen ions ( H+) are known to have no taste which implies it being tasteless. It is also important to note that it has no smell too when perceived (odorless).

One compound that contributes to the "seashore smell" at beaches in Hawaii is dictyopterene D', a component of a brown edible se
Luba_88 [7]

Answer:

Explanation:

There are few simple rules in organic chemistry which a person must learn.

1. In predicting a structure from ozonolysis, number of oxygen present in products must be counted. In this particular example, there are 2+3+1 = 6 oxygen atoms are present in three molecules. This means that there should be at least three confirmed double bonds must be present in the molecule of Dictyopterene.

2. There are in total of 3+5+3 = 11 carbon atoms present, making 2^11 = 2048 possible structures for this particular structure. But since there are three double bonds present, this will reduce the number of possible structures as well.

3. Questions also says that when fully hydrogenated, the molecule generates Butylcycloheptane. That means that our base molecule is Butylcycloheptane and this molecule contains at least three double bonds.

So, first we draw the molecule of butylcycloheptane. After this, we think of were double bonds could be present. We do have the products. Let's make their structures first. I have also mentioned the possible breakup where the ozonolysis has occured by color code. You can see them in the reference image attached.

Part 1 out of 2: There is only one chiral carbon present in the molecule and have two possible isomers. Cis and Trans. Only one stereogenic carbon is present, that's why two possible isomers. Image attached.

Gaseous methanol (CH4O) reacts with oxygen gas to produce carbon dioxide gas and liquid water. Balanced the equation using the l
NikAS [45]

Answer:

The sum of the coefficients in the balanced equation is 11

Explanation:

A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.

The balance reaction of combustion for methanol is:

2CH₃OH (l) + 3O₂(g) →  2CO₂(g)  +  4H₂O (g)

Coefficients from stoichiometry are 2, 3, 2 and 4

Sum =  2 + 3 + 2 + 4 = 11

Write a balanced chemical equation for the standard formation reaction of solid chromium(iii) nitrate crno33 .
Drupady [299]

Explanation:

Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.

Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.

2Cr(s)+3N_2(g)+9O_2\rightarrow 2Cr(NO_3)_3(s)

A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate

Cr(s)+\frac{3}{2}N_2(g)+\frac{9}{2}O_2\rightarrow Cr(NO_3)_3(s)
