Answer:
Answer is A
Explanation:
What type of reaction present on this equation 2mgl + mn(so) → 2mgso + mnl
The type of reaction present in the equation(2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄) is a double displacement reaction.
Balanced chemical reaction2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄
The reactant of the reaction is on the left side while the product of the reaction is on the right side.
Double displacement (Metathesis)Double displacement is a kind of reaction in which the two reacting compounds exchange their radicals or ions to form two new compounds. The anions and cations of the two different molecules switch places to form a new compound.
The reaction type is a double displacement reaction because the cations (mg and mn) and anions(so₃²⁻ and l⁻) switch positions.

Calculate the ph when 20.0 ml of 0.150 m koh is mixed with 20.0 ml of 0.300 m hbro (ka = 2.5 × 10⁻⁹)
The pH of the solution is 10.74. the pH refers to the hydrogen ion concentration. It is a measure of the acidity of the solution.
What is pH?pH is the degree of acidity or alkalinity of a solution.
The equation of the reaction is;
KOH + HBrO ==> KBrO + H2O
The number if moles of KOH =20.0 ml x 1 L / 1000 ml x 0.150 mol/L = 0.003 moles KOH
The number of moles of HBrO = 20.0 ml x 1 L / 1000 ml x 0.300 mol/L = 0.006 moles HBrO
Since the reaction is 1:2;
[BrO-] = 0.003 mols / 0.04L = 0.075M
Now the pH, is obtained from;
KBrO + H2O ==> KOH + HBrO
BrO- + H2O ==> HBrO + OH-
Kb of BrO- = 1x10-14 / 2.5x10-9 = 4x10-6
Kb = 4x10-6 = [HBrO][OH-] / [BrO-]
From the ICE table;
4x10^-6 = (x)^2 / 0.075
x = 5.48x10-4 M = [OH-]
pOH = -log 5.48x10-4 M = 3.26
pH = 14 - pOH
pH = 10.74

block x of mass m slides across a horizontal surface where friction is negligible. block x collides with block y of mass 2m that is initially at rest, as shown in figure 1. after the collision, both blocks slide together with a speed vs , as shown in figure 2.
The kinetic energy of the two-block system with the given masses before the collision is determined as ³/₂Mvs².
Kinetic energy of the blocks before collisionThe kinetic energy of the blocks before the collision is calculated as follows;
For a negligible friction effect, the kinetic energy of the two - block system after the collision is equal to the kinetic energy before the collision.
K.E(initial) = K.E(after)
K(after) = ¹/₂(m₁ + m₂)vs²
K(after) = ¹/₂(m + 2m)vs²
K(after) = ¹/₂(3m)vs²
[tex]K.E(after) = \frac{3}{2} Mv_s^2[/tex]
Thus, the kinetic energy of the two-block system with the given masses before the collision is determined as ³/₂Mvs².

A jar contains five black balls and seven white balls. two balls are drawn sequentially, but the first ball is replaced before the second drawn. the probability of drawing two white balls, given that at least one of the balls is white, is 7/17.
The probability both balls are black, given that the first one is black, is gotten as; ⁵/₁₂
What is the probability of Selection?
By using the probability of an event formula,
There are 5 black balls out of a total of 12 balls, so the probability of obtaining a black on a single draw is ⁵/₁₂, and the probability of obtaining a white is ⁷/₁₂
Since the balls are drawn with replacement, the two draws are independent events.
Use Multiplication and Union Rules to obtain the following probability:
P(F) = P(B, B) + P(B, W)
P(F) = (⁵/₁₂ * ⁵/₁₂) + (⁵/₁₂ * ⁷/₁₂)
P(F) = ⁵/₁₂
