Answer:
d
Explanation:
Generally, it is transported through pipes so I think statement d is incorrect.
The ore contains 55.4% calcium phosphate (related to the mineral apatite) so the amount of Ca3(PO4)2 is 55.4%x=1000g so x=1000/0.554= 1.805kg. Now for the % of P in this amount of calcium phosphate, use all the masses of the elements in Ca3PO4= Ca=40.078 x 3= 120.23 and (PO4)2= (30.974+64)2=189.95 (NB oxygen is 16 mass x 4 =64) so the total mass is 310.2 and we have 61.95 of P (Pmass x 2) so 61.95/3102.= 0.19 or 19% P. So of the 1.805 x 0.19= 0.34kg of phosphorus.
Answer:
The answer is
<h2>22 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 44 g
volume = 2 mL
The density of the liquid is
We have the final answer as
<h3>22 g/mL</h3>
Hope this helps you
1. CaS
2. Nitrogen forms an anion with a -3 charge.
3. S
4. Ca2N3
5. Mg3N2. Magnesium nitride
6. CaO. So 1,1
7. 2- O2- (2- is super scripted). It is also an anion, which is a negatively charged ion.
8. That would be aluminum iodide AlI3, also called aluminum triiodide.
9. LiCI
These should be correct. Hope I helped. ^~^
An increase in pressure increasing the billing point is an example of a physical property.
- The term "boiling point" describes the temperature at which a liquid, which is being boiled, changes from a liquid to a vapor when its pressure equals that of its environment.
- Physical changes are those that take place when a material's structure is the same both before and after the change.
- When a substance is changed into another chemical substance, this is known as chemical transformation.
- When describing the state of a physical system, a substance's physical qualities are those that can be measured.
- A substance's characteristic that is seen in a chemical reaction is referred to as a chemical property.
As it demonstrates the physical state, the increase in pressure with boiling point is an example of a physical property.
