As soon as the metal gets into the water a temperature transfer will start between both of them resulting in
1. Metal will cool down.
2. Some water will get evaporated.
3. Temperature of water will rise.
4. As the metal gets into the water, a sound like chissssss will be heard.
Hope it helps.
Don't be shy and say thx.<span />
Answer:
0.091 mol/L
Explanation:
Molarity of a substance , is the number of moles present in a liter of solution .
M = n / V
M = molarity ( unit = mol / L or M )
V = volume of solution in liter ( unit = L ),
n = moles of solute ( unit = mol ),
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the data of the question , it is given that ,
w = 1.5 g
V = 220 mL
Since ,
1 mL = 1/1000L
V = 0.220 L
As we known , the mass of bleach NaOCl is ,
m = 74.44 g/mol
from the above equation , moles can be calculated as -
n = w / m
n = 1.5g / 74.44 g/mol
n = 0.0201 mol
Molarity of the solution is calculated as ,
M = n / V
M = 0.0201 mol / 0.220 L
M = 0.091 mol/L
Each part of the body of an animal is made up of cells.
Answer:
Kp = P(SO2) * P(O2) / P(SO3)
Explanation:
The equation is given as;
SO3(g) --> SO2(g) + O2(g)
In the pressurer equilibrium constant expression, only the gaseous entities are considered.
It is given as;
Kp = P(products) / P(reactants)
Product are SO2(g) and O2(g)
Reactant is SO3(g)
Kp = P(SO2) * P(O2) / P(SO3)
