P. Cyanide is toxic to clover plants because they use cytochrome c oxidase for electron transport in the mitochondria.
The correct option is B.
Where is cyanide found?Various bacteria, fungi, and algae have the ability to produce cyanides. Tapioca, spinach, willow shoots, almonds, string beans, fruit seeds, and car fumes are other items that contain cyanides.
What goods include cyanide?Smoking cigarettes and the byproducts of the combustion of synthetic fibers, including plastics, contain cyanide. Combustion products are chemicals that are released while combustion. The paper production, textiles, and plastics all use cyanide. The chemicals used it to develop pictures include it. Unfortunately, cyanide is not like other materials. By utilizing this approach, you simply cannot develop a natural tolerance to cyanide.

The number placed in front of a formula is called a coefficient. The small number within a chemical formula is called a subscript. Why do we adjust coefficients when balancing chemical equations and not subscripts?
[tex]\huge \boxed{\mathcal {\gray { A nswer :}}}[/tex]
While balancing the chemical equations, the sub scripts aren't changed because by changing sub script we actually change the compound formed, hence coefficients are changed so the compound remains the same.
for example : ( for understanding )
in balancing the given reaction,
H2 + O2 =》H2O
if we change Oxygen's sub script in " H2O "
we get,
H2O + O2 =》H2O2
but here the compound formed isn't water, it is "H2O2" (hydrogen peroxide), so we can't change the sub script.
but by changing the coefficient, we get :
2 H2 + O2 =》2 H2O

Determine which of the following statements is true.
A. A catalyst causes equilibrium to be reached faster without changing the position of the equilibrium.
B. A catalyst causes the reaction to move more slowly so that the equilibrium position can be precisely adjusted.
C. A catalyst raises the activation energy of a reaction.
D. A catalyst speeds up the rate of the forward reaction which moves the equilibrium towards the products.
Answer:
A
Explanation:
A catalyst speeds up a reaction by lowering the required activation energy, so it's not B. Like previously stated, the catalyst lowers the activation energy required, so it's not C either. This leaves us with A. Just to double check, does a catalyst speeds up a reaction? Yes! So like it says in A, a catalyst causes the equilibrium to be reached faster. Have a nice day! :)
Catalysts speed up a chemical reaction by causing equilibrium to reach quickly while maintaining the equilibrium's position. Thus, option A is true.
What are catalysts?
A catalyst increases the reaction rate by decreasing the activation energy of the reaction. As the minimum energy required by the reactants for the reaction is decreased the rate of the formation of products increases.
During the reaction, the catalyst remains unchanged and does not undergo any chemical change. It can increase the reaction rate of both irreversible and reversible reactions.
In an equilibrium reaction, the catalyst can increase the rate of both forward and reverse reaction by reaching the reaction equilibrium at a faster rate and can move the reaction toward the products as well as a reactant.
Therefore, the catalyst causes equilibrium to be reached faster.

What is the pH of a solution with an OH- ion concentration of
1.25E-4?
PLEASE HELP ASAAPPOPPP
Answer:
10.1 M
Explanation:
Applying,
pH = -log(H⁺).................... Equation 1
But,
[H⁺][OH⁻] = 1×10⁻¹⁴................ Equation 2
Where [H⁺] = Hydrogen ion concentration, [OH⁻] = Hydroxyl ion concentration.
From the question,
Given: [OH⁻] = 1.25×10⁻⁴ M
Substitute into equation 2
[H⁺][1.25×10⁻⁴] = 1×10⁻¹⁴
[H⁺] = 1×10⁻¹⁴/1.25×10⁻⁴
[H⁺] = 0.8×10⁻¹⁰ M
[H⁺] = 8×10⁻¹¹ M
Also, Substitute the value of [H⁺] into equation 1
pH = -log[8×10⁻¹¹]
pH = 10.1 M

The same amount of heat is added to a 10-g sample of each of the following metals. If each metal is initially at 20.0°C, which metal will reach the highest temperature? show your work
A. gold 0.129 J/(g °C)
B. beryllium 1.82 J/(g °C)
C. calcium 0.653 J/(g °C)
D. copper 0.385 J/(g °C)
Answer: A
Explanation:
A
Heat is the product of the mass, specific heat, and delta temperature. The gold metal will reach the highest temperature. Thus, option A is correct.
What is specific heat?Specific heat (c) is the heat required by a substance to get heated a unit mass by a unit of temperature. The specific heat is given as,
[tex]\rm c = \rm \dfrac{Q}{m \times \Delta T}[/tex]
Here, Q is the heat applied, m is the sample's mass and delta T is the change in the temperature.
The value of heat applied is the same for all the metals, so a change in temperature is calculated as,
[tex]\rm \Delta T = \rm \dfrac{Q}{c . m }[/tex]
From this, it can be said that the temperature is inversely related to the specific heat of the metal and hence the metal having the smallest c will have the highest change in the temperature.
Therefore, gold (c = 0.129 J/(g°C)) will reach the highest temperature.

How many atoms in 13.88 mole of lead? (Round to 3 sig figs)
Answer:
8.36 x 10^24 atoms/molecules
Explanation:
Avagadro's Number: 6.02214076 × 10^23
Avagadro's Number shows the number of molecules in 1 mole of substance. In this case, if there is 13.88 moles of lead, we multiply 13.88 by Avagadro's number:
(6.02214076 × 10^23)(13.88) = 8.358536 x 10^24 = 8.36 x 10^24

Solution A has a pH of 2.0. Solution B has a pH of 5.0. Which solution is more acidic? Based on the H+ ion concentrations in the two solutions, how many times more acidic?
Answer:
Solution A is 1,000 times more acidic than Sol. B
Explanation:
for pH values we use scientific notation:
-log10 c (where c is the hydrogen ion concentration) is used to notate pH value (think of it as a unit)
ie:
10^-2 is sol A 10^-5 is sol B
5-2 is 3
10^-3 = 1000
there's a diff of 1,000 between the solutions.
The acidity or alkalinity of a solution depends on the hydronium ion concentration and hydroxide ion concentration. Here the solution A of pH 2.0 is more acidic than the solution of pH 5.0.
What is pH?The pH of a solution is defined as the negative logarithm to the base 10 of the value of the hydronium ion concentration in moles per litre. When the pH of the solution is less than 7 it is acidic whereas when pH is greater than 7, it will be basic.
The pH of the solution is calculated by the equation:
pH = - log [H₃O⁺]
Then the concentration of H₃O⁺ is:
[H₃O⁺] = 10⁻pH
At pH = 2.0, [H₃O⁺] = 10⁻² = 0.01
At pH = 5.0, [H₃O⁺] = 10⁻⁵ = 0.00001
Thus here the Solution A is 1,000 times more acidic than Solution B.

Explanation:
Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present. An increase in carbon, for example, will increase the strength but decrease the ductility.

Explanation:
The number of oxidation states in the metal, M = One oxidation state
The formula of the compound formed by the metal, M = MHCO₃
We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1
Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;
The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.
I have 2.000 moles of potassium (K). How many grams of potassium chloride (KCl) can I make?
Answer:
You can make 149.1g of KCl
Explanation:
1 mole of potassium chloride, KCl, contains 1 mole of potassium, K. That means, with 2.000 moles of K we can make 2.000 moles of KCl. To solve this question we must convert these moles of KCl to mass in grams using its molar mass (Molar mass KCl = 74.5513g/mol):
