2Ag +(aq) + SO4 2-(aq)----->Ag2SO4 (s)
Answer:
103.2 g of AgCl can be made in the reaction
Explanation:
We state the reaction to analyse the problem:
AlCl₃ + 3AgNO₃ → 3AgCl + Al(NO₃)₃
We convert the mass of chloride to moles:
32 g . 1mol/ 133.34g = 0.240 moles
Ratio is 1:3. See the stoichiometry
1 mol of aluminum chloride can produce 3 moles of AgCl
Then, 0.240 will produce (0.240 . 3)/1= 0.720 moles.
We convert the moles to mass: 0.720 mol . 143.32g/1mol = 103.2 g
The answer is sublimation.
Sublimation is the chemical process whereby a solid turns into a gas without first becoming a liquid.
The word sublimation comes from the Latin word sublimare which means "raised to a higher status."
Examples of sublimation include surface layer of snow and ice turning into steam or fog without melting and dry ice which is the solid form of carbon dioxide which also undergoes sublimation.
The low temperature and sublimation makes dry ice an effective coolant or cooling agent . One of its main advantages is that it has a lower temperature than water ice and also does not leave any residue.
Answer:
M (third main energy level)
Explanation:
The third main energy level bears the first appearance of the 'd' sublevel. The principal quantum number(n) depicts the main energy levels in which an orbital is located. It takes values of n=1,2,3,4,5..... and it can be represented by the shells k,l,m,n.......
The subshells in these main orbitals are represented by s,p,d and f. For the K shell, the principal quantum number is m and its sublevel notations are s,p and d. This is where the d-sublevel first appears.
