Answer:
3Li2CO3 + Ca3(PO4)2 → 2Li3PO4 + 3CaCO3
3,1,2,3 are the coefficients.
Explanation:
Li2CO3 + Ca3(PO4)2 → Li3PO4 + CaCO3
Balanced equation is :
3Li2CO3 + Ca3(PO4)2 → 2Li3PO4 + 3CaCO3
ΔG > 0
is always true for the freezing of water.
Explanation:
- The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
- The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
- Entropy will decline elsewhere, provided it increases by at least as much elsewhere.
Answer:
NaCl will only conduct electricity in solutions
Explanation:
For electrical conduction, free mobile electrons as seen in most metals must be present or ions which are charged particles must be available for solutions and molten substances.
- Sodium chloride is an ionic compound without free mobile electrons or ions despite being ionic.
- It will maintain a subtle and unique charge stability when in solid form.
- In solid, the ions are not free to move and remain locked up in the solid mass.
- When introduced into a solution, the ions becomes free to move and this will aid electrical conduction.
Answer:
Anion is negatively charged particle.
Calcium +2. Its cation
Oxygen -2
Explanation:
An anion is a charged particle with a negative charge. Anions has charge of -1
Oxygen require two electrons to complete its octet and hence its charge is -2
Calcium is a cation and has a positive charge of +2
I don't know your options but maybe this bit of information will help, the boiling point of water is 212<span>°</span>F so at that temperature it will likely just start evaporating
