B. It is a covalent bond because electrons are being shared
C. It is an ionic bond because electrons are being transferred
D. It is a covalent bond because electrons are being transferred.

please answer this no links please!!

Answers

Answer 1

Based on the nature of the types of chemical bonding, the example illustrates covalent bonding because electrons are shared between the carbon and hydrogen atoms.

Chemical bonding

Chemical bonding or combination occurs when atoms of elements combine to form products.

Chemical bonding can either be;

ionic bonding orcovalent bonding

Covalent bonding

Covalent bonding involves a sharing of electrons by the atoms of elements involved.

Since the example shows electrons being shared between carbon and hydrogen atoms, the example illustrates a covalent bonding because electrons are shared between the atoms.

Write a balanced chemical equation for the standard formation reaction of solid calcium oxide (CaO).

Answers

Answer:

2Ca +O2 ----------> 2CaO ( Balanced Reaction)

The balanced chemical equation for the standard formation reaction of solid calcium oxide (CaO) is

Ca + O2 --> CaO2

Heya are balanced equations?

A balanced chemical equation is an equation in which the the number of atoms of each elements on both the reactant and products sides are equal.

Calcium oxide is an alkaline which is solid at room temperature and is formed by the reaction of one atom of calcium and two atoms of oxygen.

Therefore, the balanced equation of formation reaction of solid calcium oxide (CaO) is Ca + O2 --> CaO2.

How long does it take for a car driving at 10m/s to move 200m?
A.
0.05 seconds
B.
2 seconds
C.
20 seconds
D.
2000 seconds

Answers

C. 20s

Explain:
10=1
200=?
200/10=20

The time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.

What is speed?

Speed is defined as a measurement of the length of time it takes for an object to travel a certain distance.

The SI unit of speed is m/s, and speed is defined as the ratio of distance to time.

A change in speed is an example of acceleration because it is a change in velocity. Acceleration could be for positive or negative. Deceleration is another name for negative acceleration.

There are four types of speed.

Uniform speedVariable speedAverage speedInstantaneous speed

Speed can be expressed as

Speed = Distance / Time

Given, Distance = 200 m

Time = 10 m/s

Speed = 200m / 10m/s

= 20 seconds

Thus, the time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.

Taking into accoun the STP conditions and the ideal gas law, the correct answer is option e. 63 grams of O₂ are present in 44.1 L of O2 at STP.

First of all, the STP conditions refer to the standard temperature and pressure, where the values used are: pressure at 1 atmosphere and temperature at 0°C. These values are reference values for gases.

On the other side, the pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:

P×V = n×R×T

where:

P is the gas pressure.V is the volume that occupies.T is its temperature.R is the ideal gas constant. The universal constant of ideal gases R has the same value for all gaseous substances.n is the number of moles of the gas.

Then, in this case:

P= 1 atmV= 44.1 Ln= ?R= 0.082 [tex]\frac{atmL}{molK}[/tex]T= 0°C =273 K

Replacing in the expression for the ideal gas law:

1 atm× 44.1 L= n× 0.082 [tex]\frac{atmL}{molK}[/tex]× 273 K

Solving:

[tex]n=\frac{1 atm x44.1 L}{0.082\frac{atmL}{molK}x273K}[/tex]

n=1.97 moles

Being the molar mass of O₂, that is, the mass of one mole of the compound, 32 g/mole, the amount of mass that 1.97 moles contains can be calculated as:

[tex]1.97 molesx\frac{32 g}{1 mole}[/tex]= 63.04 g ≈ 63 g

Finally, the correct answer is option e. 63 grams of O₂ are present in 44.1 L of O2 at STP.

We mix 88 grams of oxygen gas with 33 grams
of argon gas in a volume of 2400 mL at 62◦C.
What will be the final pressure of the gas
mixture?

Answers

The final pressure of the gas mixtures is 72.48 atm.

The given parameters;

mass of the oxygen = 88 gramsmass of the argon, = 33 gramsvolume of the gaseous mixture, V = 2400 mL = 2.4 L

The number of moles of the gases is calculated as follows;

[tex]number \ of \ moles \ of \ oxygen = \frac{88}{16} = 5.5 \ moles\\[/tex]

[tex]number \ of \ moles \ of \ argon = \frac{33}{40} = 0.825 \ moles\\[/tex]

The total number of moles of the gas mixture;

= 5.5 + 0.825

= 6.325 moles

The final pressure of the mixture is calculated as follows;

PV = nRT

[tex]P = \frac{nRT}{V} \\\\P = \frac{6.325\ mol \times (0.0821 \ L.atm/mo.K) \times (62+273)}{2.4 \ L} \\\\P = 72.48 \ atm[/tex]

Thus, the final pressure of the gas mixtures is 72.48 atm.
