Answer:
16.54 mL
Explanation:
From the question;
- Density of mercury of 13.6 g/mL
- Mass of the mercury metal is 225 g
We are needed to determine the volume of the mercury metal;
We need to know that;
- Density is given by dividing the mass of a substance by its volume.
That is;
Density = Mass ÷ Volume
Rearranging the formula;
Volume = Mass ÷ Density
Therefore;
Volume = 225 g ÷ 13.6 g/mL
= 16.54 mL
Thus, the volume of the mercury needed is 16.54 mL
Answer:
A. Iodine (falls in the same group as chlorine)
Explanation:
Their roots trap and stabilize the sediment, which not only helps improve water clarity and quality, but also reduces erosion and buffers coastlines against storms. Sea grass can further improve water quality by absorbing nutrients in runoff from the land.
Answer:
Try using Ptable or chemicalaid
Explanation:
Ptable is a great website that shows you a dynamic periodic table. It can show you which elements are Halogens, Alkali metals, transition metals, noble gases, and etc!
Chemicalaid is a nice website to find out more information about specific elements, it also lists every element on the periodic table.
Answer:
Metals conduct electricity because the electrons inside the metal are relatively free to move. So when electricity is pass through metals, electrons carry electricity and spread it all over the metal. The mobility of electrons is the reason why metals conduct electricity.
