Clorox, Windex, and Wd-40
Answer:
because its hard as a rock, rn
Explanation:
<span>CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair.</span>
Answer:
The answer to your question is 8.2 g of TiF₄
Explanation:
Data
Theoretical yield = ?
mass of Ti = 5 g
mass of F₂ = 5 g
Balanced chemical reaction
Ti(s) + 2F₂ (g) ⇒ TiF₄(g)
Process
1.- Calculate the Molar mass of reactants and products
Ti = 48 g
2F₂ = 2( 19 x 2) = 76 g
TiF₄ = 48 + 76 = 124 g
2.- Calculate the limiting reactant
theoretical proportion Ti/F₂ = 48/76 = 0.63
experimental proportion Ti/F₂ = 5/5 = 1
Conclusion The limiting reactant is F₂ because the experimental proportion was lower than the theoretical proportion.
3.- Calculate the theoretical yield using the mass of F₂
76 g of F₂ --------------- 124 g of TiF₄
5 g of F₂ --------------- x
x = (5 x 124) / 76
x = 8.15 g of TiF₄
The correct answer is (c) It would have lower ionization energies than K and a lower electronegativity value than K
Explanation- The unknown element belongs to the alkali metals of periodic table. The alkali metal atoms have the largest size in a particular period of the period of periodic table. With the increase in the atomic number, the atom becomes larger.
Atomic radius decreases --> ionization energy increase---->Electronegativity increases. We can use this flow chart to compare the IE and EN of the element. As K have lower radii than the unknown element, so the IE and EN of K will be greater than the unknown element.
