Answer:
The third one from the left–the graduated cylinder.
Explanation:
The laboratory apparatus that gives an <em>"accurate" </em>or <em>"precise" </em>measurement of a liquid's volume is the<em> graduated cylinder</em>. All you have to do is to pour the liquid into the cylinder and read its measurement using the calibrated scale.
The graduated cylinder comes in different sizes, which means the scale divisions will depend on its size. When reading the measurement, it is important to take note to read at the <u><em>bottom of the meniscus</em></u> because it gives the most accurate volume.
Hey there!
The molar mass of magnesium is 24.305 grams.
The molar mass of an element is the same as the atomic mass of an element, but measured in grams.
It's on the periodic table underneath the element symbol.
Hope this helps!
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.
