Answer:
Ca3(PO4)2
Explanation:
Ca3(PO4)2 or calcium phosphate is insoluble in water.
Answer: The molarity of the base solution is 0.22 M.
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 0.1994 M
= volume of solution = 38.87 ml
= molarity of 
solution = ?
= volume of solution = Final reading - Initial reading = 36.18 - 1.16 = 35.02 ml
= valency of = 1
= valency of = 1
Therefore, the molarity of the base solution is 0.22 M.
Answer:
Carbon and phosphorus
Explanation:
The atoms of carbon and phosphorus are most likely to gain electrons from the given choices .
The reason for this is because, both carbon and phosphorus are non-metals. Most non-metals usually accept electrons.
Metals are usually electron donors .
- Metals are known for their electropositivity which is their ability to lose electrons.
- Non-metals are electronegative and will tend to have a strong affinity for electrons.
Answer:
See explanation
Explanation:
If we look at the structure of X, we will discover that X is an organic compound. The compound will certainly have a much lower melting point than sand.
This is because, sand is composed of high melting point inorganic materials.
Hence, even though the researcher accidentally spilled some sand into the the beaker containing the crystalline substance X, he does not need to be perturbed since the melting point of X is much lower than that of sand
