Answer:

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal.

What will the ratio of ions be in any compound formed from a group 1a and a group 7a nonmetals?

julsineya [31]

Group 1a elements (the first column on the left side of the Periodic table) always release one electron to form positive ions with a charge of +1. Group 7a nonmetals (the second to the last column on the right side- the rightmost column are the noble gases) always desire to gain one electron to form negative ions with a charge of -1.
Since their charges are equal and opposite, they will always combine in a 1:1 ratio.

Determine the number of atoms in 5.88 moles sodium.

ozzi

1 mole ------------ 6.02x10²³ atoms
5.88 moles ---- ?

atoms = 5.88 * 6.02x10²³ / 1

= 3.539x10²⁴ atoms

How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 30.6 moles of water vapor?

belka [17]

H₂ + CO₂ ⇄ CO + H₂O

1 mol H₂ - 1 mol H₂O
x mol H₂ - 30.6 mol H₂O

x=30.6*1/1=30.6 mol (theoretically)

There are eight consitutional isomers with the molecular formula C4H11N.

Dmitriy789 [7]

Answer:

See figure 1

Explanation:

We have to remember that in the isomer structures we have to change the structure but we have to maintain the same formula, in this case $C_4H_1_1N$ .

In the formula, we have 1 nitrogen atom. Therefore we will have as a main functional group the amine group.

In the amines, we have different types of amines. Depending on the number of carbons bonded to the "N" atom. In the primary amines, we have only 1 C-H. In the secondary amines, we have two C-N bonds and in the tertiary amines, we have three C-N bonds.

With this in mind, we can have:

-) Primary amines:

1) n-butyl amine

2) sec-butyl amine including 2 optical isomers

3) isobutyl amine

4) tert-butyl amine

-) Secondary amines:

5) N-methyl n-propyl amine

6) N-methyl isopropyl amine

7) N, N-diethyl amine

-) Tertiary amines:

8) N-ethyl N, N-dimethyl amine

See figure 1

I hope it helps!
