Venus

Venus is the second planet from the Sun and Earth's closest planetary neighbor. Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid.

A 20.00 g mixture of magnesium and zinc metal reacting with excess hydrochloric acid produced 1.152 g of hydrogen gas. what is t
mafiozo [28]

percentage of zinc= 5.985/20 X 100= 29.5%

let x represents zinc and y be magnesium so

Zinc(s) + 2HCl(aq) -----> ZnCl2(aq) +  H2(g)

Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)

1.152 g of hydrogen gas=( x/65.3 + y/24.305) 20

= 3.08 x10^-2 + 0.8295-8.30

=x=5.985

y= 4.015

percentage of zinc= 5.985/20 X 100= 29.5%

The hydrogen gas escapes, so the two products of Zinc Chloride and Magnesium Chloride will then react with Silver Nitrate. Again, I combine both of the reactions

39. Which bond is least polar?<br> A) As-C1<br> B) Bi-CI<br> C) P-CI<br> D) N-C1
garik1379 [7]

Answer:

D) N-Cl.

Explanation:

The electronegativity of the elements in Group 5 (N. P As and Bi) decreases as we go down the Group so N is the most electronegative and chlorine is less able to draw electrons away from N than from the other elements in Group 5.

Zina [86]

answer= 0.912 L or 912 mL

M(KClO3) =  122.55 g/mol

3.00 g KClO3 * 1  mol/122.55 g = 3.00/122.55 mol =0.02449 mol                

                          2KCIO3(s)=2KCI(s) + 3O2(g)

from reaction      2 mol                         3 mol

given                   0.02449 mol              x

x = 0.02449*3/2 =0.03673 mol O2

T = 24 + 273.15 = 297.15 K

PV = nRT

V= nRT/P = (0.03673 mol*0.082057 L*atm/K*mol*297.15 K)/0.982 atm =

= 0.912 L or 912 mL
