Answer:

Covalent

Explanation:

Using an electronegativity chart, such as the attached one, you see that Nitrogen (N) has an electronegativity value of 3.0. Because both molecules are the same, 3.0-3.0=0. Therefore, because the electronegativity value difference is 0, the bond must be covalent.

Which reactions are oxidation-reduction reactions? check all that apply. fes(s) 2hcl(aq) â†’ h2s(g) fecl2(g) agno3(aq) nacl(aq)

Dafna1 [17]

oxidation-reduction reactions are -

2C3H6(g) + 9O2(g) → 6CO2(g) + 6H2O(g)
Fe2O3(s) + 3CO(g) → 2Fe(l) + 3CO2(g)

For reaction,

2C3H6(g) + 9O2(g) → 6CO2(g) + 6H2O(g)

On reactant side:

Oxidation state of Carbon = +2

Oxidation state of Oxygen = 0

On product side:

Oxidation state of Carbon = +4

Oxidation state of Oxygen = -2

Here, carbon's oxidation state is rising from +2 to +4. As a result, it is oxidizing and the oxygen's oxidation state is decreasing from 0 to -2. As a result, it is decreasing.

For reaction,

Fe2O3(s) + 3CO(g) → 2Fe(l) + 3CO2(g)

When reacting:

Iron's oxidation state is +3.

Carbon's oxidation state is +2.

On product side:

Iron's oxidation state is zero.

Carbon's oxidation state is +4.

Here, carbon's oxidation state is rising from +2 to +4. As a result, it is being oxidized and the iron's oxidation state is changing from +3 to 0. As a result, it is decreasing.

Velocity , Both , Or Acceleration??

ycow [4]

Acceleration is the rate of change and is constantly positive

The answers for Acceleration:
m/s^2
Change in velocity over change in time

Velocity is the speed of the object but also involves direction can be both negative and positive

The answers for Velocity:
m/s
Can be positive or negative
Change in displacement over change in time

Both Acceleration and Velocity:
A rate of change

The fuel used in many disposable lighters is liquid butane, C4H10. Butane has a molecular weight of 58.1 grams in one mole. How

labwork [276]

First convert grams to moles using molar mass of butane that is 58.1 g

3.50g C4H10 x (1 mol C4H10)/(58.1g C4H10) = 0.06024 mol C4H10 

Now convert moles to molecules by using Avogadro’s number

0.06024 mol C4H10 x (6.022x10^23 molecules C4H10)/(1 mol C4H10) = 3.627x10^22 molecules C4H10

And there are 4 carbon atoms in 1 molecule of butane, so use the following ratio:

3.627 x 10^22 molecules C4H10 x (4 atoms C)/(1 molecule C4H10)
= 1.45 x 10^23 atoms of carbon are present
