Answer:The correct option is, 100 ml Graduated cylinder.
Explanation:Graduated cylinder : It is measuring cylinder that is used to measure the volume of a liquid. It has a narrow cylindrical shape. The marked line drawn on the graduated cylinder shows the amount of liquid that has been measured.
Erlenmeyer flask : It is also called as a conical flask or titration flask. It is a laboratory flask that has flat bottom, a conical body and a cylindrical neck. It is commonly used for the titration.
Beaker : It is a type of laboratory equipment that has cylindrical shape and it is used for the mixing, stirring, and heating of chemicals.
As per question, the graduated cylinders are more accurate and precise than Erlenmeyer flasks and beakers.
percentage of zinc= 5.985/20 X 100= 29.5%
let x represents zinc and y be magnesium so
Zinc(s) + 2HCl(aq) -----> ZnCl2(aq) + H2(g)
Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)
1.152 g of hydrogen gas=( x/65.3 + y/24.305) 20
= 3.08 x10^-2 + 0.8295-8.30
=x=5.985
y= 4.015
percentage of zinc= 5.985/20 X 100= 29.5%
The hydrogen gas escapes, so the two products of Zinc Chloride and Magnesium Chloride will then react with Silver Nitrate. Again, I combine both of the reactions

Yes
Methane also is the chief constituent of natural gas, which contains from 50 to 90 percent methane (depending on the source), and occurs as a component of firedamp (flammable gas) along coal seams.
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire

The answer is D, the attractive force between them decreases.
Although the volume that the particles take up generally increases when going from solid to liquid, particles themselves never change their size. It’s the attractive force that decreases and doesn’t pull the particles together as tightly when a solid changes to liquid.
