Answer:

M_{acid}=5.484x10^{-3}M

Explanation:

Hello,

By using the following formula, which comes from the assurance of the equivalence point:

M_{acid}*V_{acid}=M_{base}*V_{base}\\M_{acid}=\frac{M_{base}*V_{base}}{V_{acid}}

We just simply compute the acid's concentration (molarity), turning out into:

M_{acid}=\frac{0.2000M*22.62mL}{825mL} \\\\M_{acid}=5.484x10^{-3}M

Best regards.

What is the action of a catalyst
AfilCa [17]

Answer: A catalyst is a substance that speeds up the rate of a chemical reaction without being used up and remains chemically unchanged itself .

Explanation: For a reaction to take place the particles must collide with enough energy for bonds to break and reaction to occur .

BUT when a catalyst is present the reactants are able to react in a way that requires less energy ,leading to more successful collision so the reaction speeds up without the chemical composition of the catalyst being affected

NOTE: the catalyst must be chosen to suit the particular reaction

Anarel [89]

Answer:

In this diagram, the phenomenon moving from medium A which represents water to medium B that represents air is called refraction.

Explanation:

Refraction takes place when light passes through a water surface due to its refractive index which is 1.33. Air possesses a refractive index of about 1. Looking at the phenomenon moving between medium A and B, it seems to bend at the water's surface. This happens because of the bending of the light rays as they move from the water to the air. The time when the rays reach the eyes, the eyes trace them back as straight lines or lines of sight. These lines divide at a higher position than where the actual rays originated. This causes the phenomenon to appear higher and the water to appear shallower than what it is in reality.

stich3 [128]
A monkey needs to use more force and strength than a bat when swinging and they can get more momentum to push forward. and bat needs shorter limbs so they don’t have much weight to carry when they are flapping their wings. they will go faster with less mass in their arms.
