Answer:
89.6 L of CO₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2CH₃OH + 3O₂ —> 2CO₂ + 4H₂O
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Next, we shall determine the number of mole CO₂ produced by the reaction of 6 moles of O₂. This can be obtained as follow:
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Therefore, 6 moles of O₂ will react to produce = (6 × 2)/3 = 4 moles CO₂.
Thus, 4 moles CO₂ were obtained from the reaction.
Finally, we shall determine the volume occupied by 4 moles CO₂. This can be obtained as follow:
1 mole of CO₂ occupied 22.4 L.
Therefore, 4 moles CO₂ will occupy = 4 × 22.4 = 89.6 L
Thus, 89.6 L of CO₂ were obtained from the reaction.

Miniature golf is a game in which players hit a golf ball with a club, which causes the ball to roll along the flat ground. Three golf balls with the same mass were rolling on the ground. Each ball was hit by a golf club, but not from the same direction. All the golf balls changed speed as a result of being hit. Use the information in the diagram to answer.
Which golf ball(s) experienced the strongest force when hit? How do you know?
Answer:
The green golf ball because it changed speed the most.

How many joules of heat are absorbed to raise the temperature of 125 grams of water at 1 atm from 35°C to its boiling point, 100.°C.
Answer:
33962.5 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 125 g
Initial temperature (T₁) = 35 °C
Initial temperature (T₂) = 100 °C
Specific heat capacity (C) = 4.18 J/gºC
Heat (Q) absorbed =?
Next, we shall determine the change in temperature. This can be obtained as follow:
Initial temperature (T₁) = 35 °C
Initial temperature (T₂) = 100 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 100 – 35
ΔT = 65 °C
Finally, we shall determine the heat absorbed. This can be obtained as follow:
Mass (M) = 125 g
Change in temperature (ΔT) = 65 °C
Specific heat capacity (C) = 4.18 J/gºC
Heat (Q) absorbed =?
Q = MCΔT
Q = 125 × 4.18 × 65
Q = 33962.5 J
Therefore, the heat absorbed is 33962.5 J

True or False: A pendulum when started swinging, will swing for ever without stopping unless you stop it. Be sure to explain your answer.
well, yes it will continue to swing but not forever. it will just a long time but eventually stop. the reason is because of the air resistance which will continue to damp the motion until the bob stops

If H2O is removed from this reaction, what will happen?
2H2 + 02 32H20
O A. The equilibrium will not change.
B. The reaction will be reactant-favored.
O C. The reactants will react to produce more H20.
D. The product-favored reaction will stop.
Answer:
C. The reactants will react to produce more H2O.
Explanation:
According to Principle of Equilibrium, the reaction would move in such a way to annul any change imposed on a system at equilibrium.
In this question, the change is removing H2O from the reaction system. To counter this change, more H2O has to be produced.
The correct option is;
C. The reactants will react to produce more H2O.
A mixture of PCl5(g), PCl3(g), and Cl2(g) is in a 1.00 L reaction vessel. The total pressure of the reaction system is 1.40 atm at equilibrium. Then the volume of the reaction vessel is reduced from 1.00 L to 0.50 L and equilibrium is re-established at constant temperature. What is the total pressure of the system at this point?
Answer:
The total pressure immediately after the volume reduction is 2.8 atmospheres
Explanation:
The question parameters are as follows;
The initial volume of the reaction vessel, V₁ = 1.00 L
The initial pressure of the reaction system, P₁ = 1.40 atm
The final volume of the reaction system, V₂ = 0.50 L
With the assumption that the gas mixture behaves as an ideal gas, and the temperature is constant, by Boyle's law we have;
P₁·V₁ = P₂·V₂
Where;
P₁ = The initial pressure in the reaction vessel
V₁ = The initial volume in the reaction vessel
P₂ = The total final pressure in the reaction vessel after the reduction in the vessel volume
V₂ = The final volume in the reaction vessel
∴ P₂ = P₁·V₁/V₂
From which we have;
P₂ = 1.40 atm × 1.00 L/(0.50 L) = 2.8 atm
The total final pressure in the reaction vessel, P₂ = 2.8 atm.
i just need an explanation :) so the problem was " what is the mass of 5 molecules of water(H2O) , in grams?" my teacher said the answer is 1.50 x 10^-22 but i dont understand why. why is it not 1.50 x 10^24, why is the exponent negative?
Answer:
Explanation:
The exponent is negative because water molecules are absolutely tiny. You can't see a molecule of water on the palm of your hand with your naked eyes, right? If a the mass of a molecule was 1.50 x 10^24, it'd be HUGE... like absolutely massive (possible the size of your city). Molecules are just tiny, tiny particles

Write the answer in scientific notation when you multiply 2 x 104 by 3 x 104.
Answer:
6× 10⁸
Explanation:
We need to find the multiplication of 2 x 10⁴ by 3 x 10⁴.
2 x 10⁴ × 3 x 10⁴
= (3 × 2) x 10⁴ x 10⁴
= 6 x 10⁴ x 10⁴
= 6 × 10⁴⁺⁴
= 6× 10⁸
Hence, the required answer is 6× 10⁸.

Can anyone explain dipoles in chemistry?
Answer:
See explanation
Explanation:
A dipole refers to a bond in which its two ends have opposite charges. A dipole results from a large difference in electronegativity between two atoms in a bond.
For instance, consider the bond between hydrogen and chlorine in HCl. The electronegativity of hydrogen is 2.2 while that of chlorine is 3.16. The significant electronegativity difference between the two atoms leads to a charge separation.
A partial positive charge appears on the atom that is less electronegative (hydrogen) while a negative charge appears on the more electronegative atom (chlorine).
This charge separation occurs because the shared electrons of the bond are more closely attracted to chlorine making it partially negative compared to hydrogen. A dipole moment now exists in the H-Cl bond hence the molecule is said to have a dipole.
