Answer:
Option C = 200 mL
Explanation:
The volume of liquid remain same because students just transfer the liquid from the graduated cylinder with the capacity 250 mL to the graduated cylinder having the capacity of 500 mL. The volume of the liquid will remain same either it is in the large graduated cylinder or in a small graduated cylinder.
Answer:
D-Molten rock cools and turns solid
Answer:
V = 38.48 L
Explanation:
Given that,
No. of moles = 1.5 mol
Pressure, P = 700 torr
Temperature, T = 15°C = 288 K
We need to find the volume of the gas. The ideal gas equation is given by :
, R = L.Torr.K⁻¹.mol⁻¹
So, the required volume is equal to 38.48 L.
Answer:
A "squeaky" pop sound is heard.
Explanation:
When a metal reacts with hydrochloric acid, it produces the metal chloride (salt) and further liberates hydrogen gas which is a colourless and odourless gas.
Equation of the reaction
M(s) + HCl(aq) --> MgCl(aq) + H2(g)
A burning splint test is carried out for the identification of gases in the laboratory. A characteristic property of Hydrogen gas is that it gives a distinctive 'squeaky pop' sound.
Hydrogen is easily ignited, as it is flammable over a wide range of concentrations in air.
