Answer:
The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
Explanation:
Given data:
Mass of metal = 37 g
Volume of metal = 20cm³
Which metal is this = ?
Solution:
We will solve this problem by using density formula. After finding density we will check from literature which metal has a density similar to our calculated density.
d = m/v
d = 37 g/ 20cm³
d = 1.85 g/cm³
The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
The first one is right and so is eight you have to add them together to see if they go together if they dont add what is missing
Every chemical reaction requires a reactant, also called a reagents.
The rate of evaporation would decrease because of
the formation of bonds between the soap and the water.
So, no. Regular water evaporates faster than soapy water
Hello!
The formula for Copper (II) Phosphate is
Cu₃(PO₄)₂
To know how to write this formula we go from left to right. First, Copper (II). It means that the formula has the Cu⁺² ion. Now, Phosphate means that the compound has the PO₄⁻³ ion. Now we combine this two ions, giving to each one the coefficient with the number of the electric charge of the other (e.g. to Cu⁺² we'll give the charge of PO₄⁻³ which is 3 and the result will be Cu₃⁺²).
The combination gives us the result Cu₃(PO₄)₂
Have a nice day!
