Answer:

Physical changes that occur as car ages are the paint of the car started to get fade and car tires start losing its grip.

Chemical changes that occur as a car ages is the element O (Oxygen) and Al (Aluminum) react with one another to form Al2 O3 (rust).

When the car ages Most Common physical and chemical Car Problems and car complaints are discussed below:

Excessive Oil Consumption.
Radiator Leaks.
Cracked Windshield.
Malfunctioning Sensors.
Paint Problems.
Dead Battery.

These are some most common car ages issues which are discussed above.

How important is the resonance structure shown here to the overall structure of carbon dioxide?

Tcecarenko [31]

1. Resonance structures are a better description of a Lewis dot structure .

2. Best resonance structure is the one with the least formal charge.

EXPLAINATION OF RASONANCE STRUCTURE OF CARBON DIOXIDE

1.Carbon dioxide has three resonance structures .

2. The CO2 molecule has a total of 16 valence electrons ,

1C = 4 electrons

2O= 12 electrons

three resonance structures for CO2

1. The atoms in all three resonance structures have full octets;

structure 1 will be more stable because it has no separation of charge.

2. Structures 2 and 3 show charge separation caused by the presence of formal charges on both oxygen atoms.

Show the calculation of the mole fraction of each gas in a 1.00 liter container holding a mixture of 8.65 g of CO2 and 4.32 g of

Vlad1618 [11]

Answer:

0.745 and 0.245

Explanation:

Mole fraction (χ) is the number of moles of a component divided by the total number of moles in a mixture.

We must calculate the moles of each component.

Let CO₂ be Gas 1 and SO₂ be Gas 2.

1. Calculate the moles of each gas.

$\text{n} _{1} = \text{8.65 g} \times \dfrac{\text{1 mol}}{\text{44.01 g}} = \text{0.1965 mol}\\\\\text{n} _{2} = \text{4.32 g} \times \dfrac{\text{1 mol}}{\text{64.06 g}} = \text{0.067 44 mol}$

2. Calculate the total moles.

$n_{\text{tot}} = \text{n}_{1} + \text{n}_{2} = \text{0.1965 mol} +\text{0.067 44 mol} = \text{0.2640 mol}$

3. Calculate the mole fraction of each component

$\chi_{1} =\dfrac{0.1965}{0.2640} = \mathbf{0.745}\\\\\chi_{2} =\dfrac{0.06744}{0.2640} = \mathbf{0.255}$

Please help me with this, thank you so much

Basile [38]

I can’t answer the exact thing, but I know how to do it. One of the nitrogen bases always pairs with a different one, so once you know what pairs with what you just write it down. If you need more help just ask :) tip: one base will only join with a different one. One won’t join to multiple (from what I know as of now)
