Answer:
CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)
Explanation:
The solvay process is an important process in the chemical industry. In this process, ammonia gas is first dissolved in concentrated brine to form a mixture known as ammoniacal brine. This solution is made to trickle down the tower. A counter stream of carbon dioxide is forced up the tower. The two substances react to form sodium hydrogen trioxocarbonate IV. This substance is only slightly soluble and separates out as a solid sludge. The product is now dried and heated to give sodium trioxocarbonate IV.
The overall reaction of the process can be given as;
CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)
Calcium chloride is merely a by-product.
Al2O3 has a higher melting point than Na2O. This is because the ionic bond between Al3+ ions and O2- ions is stronger than that between Na+ and O2-. The charge on the Al3+ ion is larger than that of the Na+ ion
Answer:
The answer is NO
Explanation:
In every compound, the sum of oxidation number between the elements is 0.
- In NO, nitrogen acts with +2 and oxygen as usual acts with -2
- In N₂O₃, nitrogen acts with +3 and oxygen, -2
- In NO₂, nitrogen acts with +4, and oxygen -2
- In N₂O, nitrogen acts with +1, and oxygen -2
Answer:
D.
Explanation:
The hypothesis was that speed would increase with the addition of mass from passengers. The data shows that when passengers/mass are added, speed decreases.
