1) D = 13.6 g / mL
2)ethyl alcohol weighs 158g
3)ρ
_copper = 8.9 g 
Explanation:
1)
D = m / V
=306.0 g / 22.5 mL
D= 13.6 g / mL
2)
density = mass / volume
mass = density × volume
=0.789g /ml × 200.0 ml
M=158g
Ethyl alcohol weighs 158g
3)
ρ (density) = Mass / Volume
ρ
_copper = 1896 g / 8.4cm × 5.5cm × 4.6cm
= 1896g / 212.5
ρ
_copper=8.9 g
Answer:
Na
Explanation:
because sodium has 1 electrons so it loses it to be stable and so have positive charge of 1
I believe it’s evaporation?
If by classical you mean formula name it is CrPO4<span>.</span>
The procedural steps in order to get iodinate salicylamide are as follows:
- It begins first at a laboratory.
- Secondly, one has to dissolve salicylamide in ethanol.
- Then one has to add sodium iodide.
- Later on, one has to add sodium hypochlorite to the ice cold solution of salicylamide and sodium iodide.
- Thereafter one has to sodium thiosulfate.
- It is better to Acidify by a person adding about 10% of HCl.
- The one has to collect the crude product through the use of vacuum filtration.
- Lastly one then Recrystallize from hot ethanol.
<h3>What is Electrophilic aromatic substitution?</h3>
The Electrophilic aromatic substitution is known to be a kind of an organic reaction where an atom is said to be added or attached to a kind of aromatic structure (that is made up of hydrogen) is said to be replaced by an electrophile.
