5°C?
Answers
According to the information of the graph we can infer that if the water were cooled to 5°C the reaction time would be close to 30 seconds.
What would the reaction time be if the water were cooled to 5°C?To establish what would the reaction time be if the water were cooled to 5°C we have to analyze the information of the graph specially the trend. In this case, we have to take into account where are located the point that relate time and temperature.
In this case, the trend is more time with less temperature. So if the water were colled to 5°C, the time would be close to 30 seconds.

a. The dissociation constant of the weak acid HF is K₂ = [H][F]. If at equilibrium
Ka
[HF]
the concentrations of H* and F are each 2.6 x 10-3 M and the concentration of
HF is 0.010 M, what is K₂ for HF? (3 points)
Answers
Answer:
6.76*10^-4 , or 6.8*10^-4 if you consider sig figs
Explanation:
This is a bit of a confusing question, since it incorrectly states that the acid disassociation constant is simply [H+][F-].
Ka = [H+][F-]/[HF] , so plugging in the values, we get
\(K=\frac{[2.6*10^{-3}][2.6*10^{-3}]}{[0.01]}\\K=\frac{[2.6*10^{-3}]^2}{[0.01]}\\K=0.000676=6.76*10^{-4}\)
If we were to use the equation in the question, Ka=[H+][F-], we would get the answer 6.76 * 10^-6 , which is not the Ka for HF
Nigeria experiences several more hours of daylight in summer than in winter. Which statement helps explain this observation?
Answers
Answer:
Earth is tilted on its axis
Explanation:
Whenever Earth is tilted on its axis, the tilt of the earth's rotational axis causes Nigeria to have longer days in the summertime, beginning in June, compared to the winter period. The tilting of the earth also causes Nigeria to experience longer nights in the winter.
The earth’s axis of rotation is tilted at an angle of 23.5 degrees compared to the earth's orbital plane. Such tilting of the earth is what causes Nigeria to experience longer hours during the day in the summer when the Northern Hemisphere is titled toward the sun starting around June 20 or 21.
4. The temperature of a fixed mass of gas in a rigid container is decreased from 127.00
degrees Celsius to 27.0 degrees Celsius. The initial pressure was 1.5 atm. Which is
closest to the new pressure after cooling?
A) 0.5 atm
B) 1 atm
C) 2 atm
D) 2.5 atm
Can you explain how you got the answer as well ?
Answers
Answer:
B) 1 atm
Explanation:
According to Gay-Lussac's law, the pressure of a given amount of gas at constant volume is directly proportional to its temperature (in Kelvin). This is mathematically expressed as:
P₁/T₁ = P₂/T₂
From the problem, we have the following data:
P₁= 1.5 atm
T₁= 127 °C + 273 = 400 K
T₂= 27 °C + 273 = 300 K
Thus, we calculate P₂ - final pressure - as follows:
P₂ = P₁/T₁ x T₂ = (1.5 atm)/(400 K) x 300 K = 1.125 atm
Therefore, the option which is closest to the new pressure after cooling is B) 1 atm

dioxide in an electrical arc furnace with carbon:
calculate the yield:
Si0, + C - 2C0 + Si
Answers
SiC + 2CO = Si02 + 3C (7).
2C + SiO = 2C + CO (8). A typical submerged-arc furnace process involves adding a nearly stoichiometric mixture of silica and carbon.
How do we figure out yield?
You may get the percent yield using the following formula to express the effectiveness of a reaction: Yield percentage is calculated as (actual yield/theoretical yield) multiplied by 100. A 90% percent yield means that 10% of the resources were lost and that the reaction was 90% efficient (they failed to react, or their products were not captured).
Divide the theoretical yield by the experimental yield. Calculate the percent yield by multiplying this value by 100.

Answers
Answer:
3,5-dimethyl-2-octene
Explanation:
The parent chain will be choosen based on the highest value. In this case, if we count from top to bottom, we'll get seven carbon, however if we count from the second carbon, going left and then down, we'll get eight carbon. So the parent chain is octene
The double bond is located at the second carbon and the methyl groups are located on carbon 3 & 5. Since there are two methyl groups, we add di- in front of methyl to indicate two methyl groups present.
Note: The functional group has to be prioritise and it needed to be a part of the parent chain. In this case, the functional group is the double bond. (alkene)

The mixture of NH4Cl and CH3NH2 in aqueous solution would be an effective buffer solution.
How to determine the mixture that would be an effectiveThe mixture of HCOOH and NaHCOO would be an effective buffer solution. The other options would not be effective buffer solutions because they either do not contain a weak acid and its conjugate base or the pKa values of the weak acid and its conjugate base are too far apart.
A buffer solution is a solution that resists a change in pH upon addition of small amounts of acid or base.

A sample of neon gas has a volume of 7.2 mL at a pressure of 1.5atm. What is the pressure exerted by the gas if the volume is increased to 28.8 mL at constant tempature
Answers
The pressure exerted by the neon gas, when the volume is increased from 7.2 mL to 28.8 mL at constant temperature, can be calculated using Boyle's Law. The pressure exerted by the neon gas, when the volume is increased to 28.8 mL at constant temperature, is 0.375 atm.
Boyle's Law states that at constant temperature, the product of the pressure and volume of a gas remains constant. Mathematically, it can be expressed as P₁V₁ = P₂V₂. This law allows us to calculate the change in pressure when the volume changes.
In this case, the initial volume (V₁) is given as 7.2 mL, and the initial pressure (P₁) is 1.5 atm. The final volume (V₂) is 28.8 mL. By substituting these values into Boyle's Law equation, we can solve for the final pressure (P₂).
When we perform the calculations, we find that the pressure exerted by the neon gas, when the volume is increased to 28.8 mL, is 0.375 atm. As the volume increases, the pressure decreases due to the inverse relationship between pressure and volume.
Using Boyle's Law: P₁V₁ = P₂V₂
Given:
Initial volume (V₁) = 7.2 mL
Initial pressure (P₁) = 1.5 atm
Final volume (V₂) = 28.8 mL
To find the final pressure (P₂):
P₂ = (P₁ * V₁) / V₂
= (1.5 atm * 7.2 mL) / 28.8 mL
= 0.375 atm
Therefore, the pressure exerted by the neon gas, when the volume is increased to 28.8 mL at constant temperature, is 0.375 atm.

which type of substance would be best for use in a cooling system a gas with a low specific heat, a liquid with a low specific heat, a liquid with a high specific heat, a solid with a high specific heat
Answers
When choosing a substance for use in a cooling system, we want a substance that can absorb a large amount of heat without undergoing a significant temperature change. This is where the specific heat capacity of a substance comes into play.
The specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of one unit of mass of the substance by one degree Celsius (or Kelvin). A substance with a high specific heat capacity requires more heat to raise its temperature by a certain amount than a substance with a low specific heat capacity. Therefore, a substance with a high specific heat capacity would be best for use in a cooling system.
Out of the options given, a liquid with a high specific heat would be the best choice for use in a cooling system. Liquids have a higher specific heat than gases, which makes them better at absorbing and storing heat. Additionally, liquids have a higher thermal conductivity than solids, which means they can more efficiently transfer heat from one location to another.
Moreover, among the liquids, water is a commonly used coolant due to its high specific heat capacity, which means it can absorb a large amount of heat without undergoing a significant temperature change. Additionally, water has a high boiling point, which makes it effective at absorbing heat from high-temperature sources without boiling and evaporating.
In summary, a liquid with a high specific heat, such as water, would be the best choice for use in a cooling system due to its ability to absorb and store heat efficiently.
