Answer:
Potassium
Explanation:
The symbol for the element with a mass number of 169 is Tm for Thulium.
The letters to unscramble are S, Si, Tm, P, Au, and o.
The mystery element is Potassium.
Hope that helps.
Answer:
Theoretical yield: 16.68g Limiting reactant: Ti %yield=97.12%
Explanation:
Balanced reaction : Ti(s) +2 Cl2 (g) -> TiCl4(s)
g of substance = # of mole x molar mass
# of mole= g of substance/molar mass
%yield= actual yield x100/ theoretical yield
Ti is limiting reactant since it has the smallest amount of moles- 0.08795 causing it to run out first
In the equation given above, the oxidizing agent is FeO.
An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide.
Data:
Molar Mass of Nickel = 58,7 g/mol
Solving:
58,7 g → 1 mol
y -------→ 2.63 mol
Solving: (They are proportional measures, the rule of three is made (directly proportional)
multiply cross
M (NaCl) = n × M = 3.75 × 58.5 =
219.375 g
M (NaCl) = 23 + 35.5 = 58.5 g/mol
