Explain how an electric car might still run on fossil fuels.
Answer:
Explanation:
When you use electricity to charge your car, you can integrate renewable resources like solar into the fueling process. Without solar, your electric vehicle is still effectively running off of fossil fuels – it's just the fossil fuels utilized at the power plant and not within your engine.
Fossil fuels include substances like natural gas, coal, and oil. It is possible for electric cars to run on these fossil fuels. Fossil fuels like coal are burnt up to generate electricity. So when cars run on electricity, they are indirectly tapping into fossil fuels.
As the world continues to seek measures to reduce carbon emissions, electric cars are gradually becoming an option. While it is true that these fossil fuels might not be used directly on electric cars, they still find use indirectly in these cars. When coal is burnt up at the power plant to generate electricity, electric cars tap into fossil fuels indirectly.Learn more here:

What are the types of changes that occur when matter is heated ? Which of these changes produce new substances ?
When you heat something, you add energy to it. This causes the particles to move faster and farther apart. Heating solids turns them into liquids. Turning a solid into a liquid is called melting. Chemical Changes are also called Chemical Reactions. Chemical reactions involve combining different substances. The chemical reaction produces a new substance with new and different physical and chemical properties.
If a reaction releases 675,000 Joules, how many kcal does it release?
Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Explanation:
According to the standard conversion,
[tex]1 Joule = 0.000239006 kcal[/tex]
Therefore, 675,000 Joules will be converted into kcal as follows.
[tex]1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal[/tex]
Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Fluorine will be most reactive with gold.
What is fluorine?
Of almost all of the elements, fluorine seems to be the most electronegative as well as reactive. Fluorine would be a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen would that be. It produces oxygen and even the incredibly corrosive hydrofluoric acid when it combines strongly with water.
What is reactive?Reactivity would be a substance's capacity to chemically combine with several other substances. Iron, for instance, reacts vigorously with oxygen.
As you move down the group, the halogens, which are non-metal elements in Group 7, become less reactive. In contrast to the alkali metals within Group 1 of the particular periodic table, this trend is the opposite. One of the most reactive elements in Group 7 was fluorine.

Which forces of attraction do you think are stronger, the attractions that are broken or the new attractions that are formed? Explain your reasoning. *
Answer: The forces of attraction are stronger in new attractions that are formed.
Explanation:
When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.
During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.
Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.

I have 130 L of gas in a piston at a temperature of 250°C. If I cool the gas
until the volume decreases to 85 L, what will the temperature of the gas be?
This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally. Here, we are given the new volume of the gas after cooling, and we want to determine to what temperature the gas was cooled.
To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for T2, which we can obtain by rearranging the equation into T2 = V2T1/V1. Given V1 = 130 L, T1 = 250 °C (523.15 K), and V2 = 85 L:
T2 = (85 L)(523.15 K)/(130 L) = 342 K or 68.9 °C. If sig figs are to be considered, since all the values in the question are given to two sig figs, the answer to two sig figs would be either 340 K or 69 °C.
Gases show great uniformity in their behaviour irrespective of their nature. The concept Charles's law is used here to determine the new temperature of the gas. The new temperature of the gas is 341.96 K.
What is Charles's law?At constant pressure, the volume of a given mass of gas is directly proportional to the temperature on Kelvin scale. The absolute scale of temperature is introduced by the scientist Charles. The temperature at which gases supposed to have zero volume is called the absolute temperature.
Mathematically the Charles's law can be expressed as:
V = constant × T
V / T = constant
For two different gases, the equation is:
V₁ / T₁ = V₂ / T₂
T₂ = V₂T₁ / V₁
85 × 523 / 130 = 341.96 K
Thus the new temperature of the gas is 341.96 K.

What is the freezing point, in °C, of a solution made with 1.31 mol of CHCl₃ in 530.0 g of CCl₄?
Answer:
-96.6°C
Explanation:
Given:
moles CHCl3 = 1.31 molmass CCl4 = 530.0 gmass CCl4 = 530.0 g * (1 kg / 1000)
mass CCl4 = 0.5300 kg
First calculate the molality (m) of the solute, which is the moles of solute divided by the kg of solvent ([tex]\frac{moles}{kg}[/tex]):
molality CHCl3 = (mass moles CHCl3) / (mass CCl4 in kg)
molality CHCl3 = (1.31 mol) / (0.5300 kg)
molality CHCl3 = 2.471698m
Decrease in freezing point of solvent = (Kf) * (molality of solute)
Decrease in freezing point of CCl4 = (Kf) * (molality CHCl3)
Decrease in freezing point of CCl4 = (29.8°C/m) * (2.47m)
Decrease in freezing point of CCl4 = 73.6566°C
Then use the molality of the solute to calculate the change in freezing point and subtract the change from the original freezing point.
Freezing point of solution =
(freezing point of pure solvent) - (Decrease in freezing point)
Freezing point of solution = (-22.9°C) - (73.66°C)
Freezing point of solution = -96.6°C

Explanation:
The weight of the elephant is 4500 kg, and the area of the sole of one of its legs is 1700 cm2. Calculate the pressure of the elephant on the ground.
Answer:
64852.94 N/m²
Explanation:
From the question,
P = F/A.................... Equation 1
Where P = Pressure of the Elephant on the ground, F = Weight of the Elephant, A = Area of the sole of the four legs.
But,
F = mg.............. Equation 2
Where m = mass of the elephant, g = acceleration due to gravity
Substitute equation 2 into equation 1
P = mg/A............ Equation 3
Given: m = 4500 kg, A = (1700×4) cm² ( The elephant has four legs) = 6800 cm² = 0.68 m²
Constant; g = 9.8 m/s²
Substitute these values into equation 3
P = (4500×9.8)/0.68
P = 64852.94 N/m²

Calculate how many moles of SO2 can be produced with when given 75 grams of CS2.
Now calculate how many moles of SO2 can be produced with when given 96 grams of O2.
Which one is the limiting reactant (75 grams of CS2 or 96 grams of O2)? How do you know?
Answer:
1. 9600 moles
2. 4096 moles
Explanation:
CS2 + 3 O2=> CO2 + 2 SO2
1. The ratio for CS2: SO2 is :
1:2
If there are 75g of CS2 then there are:
75 × 2= 150g of SO2
Moles = mass × Mr
Moles = 150 × 64
Moles = 9600
2. The ratio for O2 : SO2 is:
3:2
If there are 96g of O2 then there are:
96 × 2/3 = 64g of SO2
moles = mass × Mr
Moles = 64 × 64
Moles = 4096

A solution has [OH-]=3.5*10^-6. Based on that, what must be true about this solution?
Answer:
Option B. It is a basic solution.
Explanation:
To know which option is correct, let us calculate the pH of the solution.
First, we shall determine the pOH of the solution. This is illustrated below:
Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶
pOH =.?
pOH = –Log [OH¯]
pOH = –Log 3.5×10¯⁶
pOH = 5.5
Finally, we shall determine the pH. This can be obtained as follow:
pOH = 5.5
pH =?
pH + pOH = 14
pH + 5.5 = 14
Collect like terms
pH = 14 – 5.5
pH = 8.5
The pH scale reads as follow:
0 to 6 => Acidic
7 => Neutral
8 to 14 => Basic
Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.
