Large hydrocarbons have what characteristics?

Chemistry
1 answer:
QveST [7]3 years ago
5 0
The answer is D because large hydrocarbons have a higher number of carbon which means an increase in boiling point and also rate of flow decreases, so they become solids.

Please help me, I really don't want to fail but I don't know how to do this
Brrunno [24]

Answer:

A)

<u>4, 7, 4, 6</u>

B)

<u>12 moles</u>

Explanation:

NH_{3}(g) + O_{2}(g) \: → NO_{2} + H_{2}O(g)

__↑______↑

8.00 mol | 14.00 mol

________________

NH_{3}(g) + O_{2}(g) \: → NO_{2} + H_{2}O(g)

You can turn this into a system of variables which are solvable.

To do this, create variables for the coefficients of each compound in the reaction respectively.

a(NH_{3}(g)) + b(O_{2}(g)) → \\c(NO_{2}) + d(H_{2}O(g))

Because to be balanced, the count of atoms in each element of the compound correspond to the coefficient of the variable in that compound so that the count of the left (reactant) side is set equal to the right (product) side.

a corresponds to the coefficient of the first compound, b corresponds to the coefficient of the second compound, c corresponds to the coefficient of the third compound, and d corresponds to the coefficient of the fourth compound.

(Reactant = Product)

Reactant: 1a [N] Product: 1c.

Reactant: 3a [H] Product: 2d.

Reactant: 2b [O] Product: 2c + 1d.

Thus the system is:

1a = 1c

3a = 2d

2b = 2c + 1d.

Then just use the substitution methods to solve.

What is the mass number of an atom that has six protons , six electrons and eight neutrons
Tresset [83]

Answer:

14

Explanation:

Given parameters:

Number of protons  = 6

Number of electrons  = 6

Number of neutrons = 8

Unknown:

Mass number  = ?

Solution:

The mass number of an atom is the sum of protons and neutrons in an atom;

 Mass number  = number of protons + number of neutrons

 Mass number  = 6 + 8  = 14
