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:

The stable nuclei can be identified if the count of proton and neutron are same then nuclei will be stable.
What is stable Nuclei?That kind of nuclei which posses identical number of proton and neutron as well can be referred as stable nuclei. For example: The isotope of carbon [tex]C^{12}[/tex] has 6 proton and 6 neutron as well. Hence it might be considered as stable nuclei.

Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 1Number of atoms on product side are as follows.
Al = 1Cl = 1Cs = 1To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.
Hence, now the equation will be as follows.
[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 3Number of atoms on product side are as follows.
Al = 1Cl = 3Cs = 3Thus, we can conclude that this equation is balanced.

Barium + Aluminum nitrate —> makes what ?
Answer:
Aluminum sulfate with barium nitrate to produce burin and aluminum nitrate
Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]
Chemical reactions are essential natural processes that take place and are in charge of the innumerable alterations and transformations we experience every day. They include the forming and breaking of chemical bonds between atoms, which causes the atoms to be rearranged to produce new compounds with various properties. The concepts of mass and energy conservation control chemical processes. The idea of balanced chemical equations came about because the total number of atoms of each element involved in a reaction stays constant both before and after the reaction. Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Write two paragraphs about what would happen if your whole body was put in a low pressure environment ?
Answer:
Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. This statement is true.
What are conifers ?Conifers are a type of gymnosperm plants bearing cone like structures in which the seeds are located. Don't be fooled by the fact that coniferous woods are widespread around the world. Some of the wildest trees in the world can be found there.
Hyperion, a coastal redwood tree, is the tallest tree in the world, reaching a height of 379 feet, equivalent to a 35-story structure. From Siberia to Canada, coniferous rainforest biomes can be found. They have cold winters and warm to hot summers.
Temperatures in coniferous forests are quite low all year long. Summertime temperatures range from -7°C to 21°C, while the average wintertime temperature ranges from -54°C to -1°C. Hence, the statement is true.

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.

The difference between the potential energy of the products and the potential energy of the reactants is *
Change in entropy
Heat of reaction
Activation energy
Reaction complex
Answer: Heat of reaction
Explanation:
Change in entropy is the difference between the entropy of products and the entropy of reactants.
Heat of reaction is the energy released or absorbed during the course of the reaction. It is difference between the potential energy of the products and the potential energy of the reactants.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
Reaction complex is the short lived intermediate formed when reactants are coverted to products.

The pressure in a car tire is 178 kPa at 37°C. After a long drive, the pressure is 275 kPa. What is
the new temp of the air in the tire, assuming the volume is constant?
Answer:
T₂ = 478.93 K
Explanation:
Given that,
Initial pressure, P₁ = 178 kPa
Initial temperature, T₁ = 37°C = 310 K
Final pressure, P₂ = 275 kPa
We need to find the new temp of the air in the tire, assuming the volume is constant. We know that,
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{275\times 310}{178}\\\\T_2=478.93 K[/tex]
So, the new temperature is equal to 478.93 K.

Argon has a pressure of 34.6 atm. It is transferred to a new tank with a volume of 456 L and pressure of 2.94 atm. What was the volume of the original container?
Answer:
38.75 L
Explanation:
From the question,
Applying Boyles Law,
PV = P'V'....................... Equation 1
Where P = Original pressure of the Argon gas, V = Original Volume of Argon gas, P' = Final pressure of Argon gas, V' = Final Volume of Argon gas.
make V the subject of the equation
V = P'V'/P.................... Equation 2
Given: P = 34.6 atm, V' = 456 L, P' = 2.94 atm.
Substitute these values into equation 2
V = (456×2.94)/34.6
V = 38.75 L

If the hydroxide ion concentration of a solution is 3.26 x 10-6 M, is it an acidic or a basic solution?
Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.
