Answer:

because water wets stuff expect for fire.

Answer:

The meaning of wet is covered or saturated with water or another liquid, showing that is a glass is covered in water it is considered wet.

Explanation:

Answer:

Option A. KCl (aq)

Option D. Mg(OH)₂(s

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

MgCl₂(aq) + KOH(aq) —>

In solution, MgCl₂(aq) and KOH(aq) will dissociate as follow:

MgCl₂(aq) —> Mg²⁺(aq) + 2Cl¯(aq)

KOH(aq) —> K⁺(aq) + OH¯(aq)

MgCl₂(aq) + KOH(aq) —>

Mg²⁺(aq) + 2Cl¯(aq) + 2K⁺(aq) + OH¯(aq) —> 2K⁺(aq) + 2Cl¯(aq) + Mg(OH)₂ (s)

MgCl₂(aq) + KOH(aq) —> 2KCl (aq) + Mg(OH)₂(s)

Thus, the products of the above reaction are: KCl(aq) and Mg(OH)₂(s)

Thus, option A and D gives the correct answer to the question.

Answer:

Correct answer-C 5.3g

Explanation:

Molarity = no. of moles of solute/ volume of of solution in litre

olarity = no. of moles of solute/ volume of of solution in litreno of moles of solute = 0.125×0.25=0.03125

olarity = no. of moles of solute/ volume of of solution in litreno of moles of solute = 0.125×0.25=0.03125one mole AgNO3 weighs 169.87 gm,

olarity = no. of moles of solute/ volume of of solution in litreno of moles of solute = 0.125×0.25=0.03125one mole AgNO3 weighs 169.87 gm,so the mass of 0.03125 moles of AgNO3 = 0.03125×169.87= 5.3084g

The grams of AgNO₃ are needed to prepare 0.125 M solution in 250 mL of water is 5.3 grams.

Moles is a unit which is used to define any amount and it is calculated as:

n = W/M, where

W = required mass

M = molar mass

Given molarity of AgNO₃ = 0.125 M

Volume of water = 250mL = 0.25L

moles (n) from the molarity (M) will be calculated as:

n = M × V

n = (0.125)(0.25) = 0.0312 moles

Now we calculate the mass of AgNO₃ by using the above formula as:

W = (0.0312mol)(169.87g/mol)

W = 5.30 g

Hence option (c) is correct.

Answer:

Blood is liquid and red, just like a red river. And for humans without blood there is no life because there is nothing to transport nutrients and oxygen to the body cells. Hence blood is the red river of life.

Answer:

i think its because of how the blood is one of the main reasons we are alive today. And without it we'd die

Answer:

Q.1

Given=

V1=6.5ltr

P1=191.0kPa

T1= 750.pK

P2= 101.3kpa

T2= 298K

V2=?

Combined gas law: P1V1/T1 = P2V2/T2

 Use the gas laws for pressure, volume and temperature calculations

Now,

191.0×6.5/750= 101.3×V2/298

V2 = 191.0×6.5×298/750×101.3

On solving further

V2 = 4.86 ltr!

4.86 volume with the steam occupy in the atmosphere!

Q.2

Scientific Reasoning:-

Temperature is directly to proportional to the pressure in second scenario the temperature was reduced to nearly half of the first one hence the pressure also decreased simultaneously, and we all know according to charles law The volume of a given gas sample is directly proportional to its absolute temperature so the decreasing temperature affected the amount of volume that decreased!
