“Spark” or “trigger” are not synonyms for a precipitate.

A precipitate doesn’t cause anything so it can’t “spark” or “trigger” anything.

A precipitate is a solid that forms during a chemical reaction, so I would go with “solid” as your synonym.

How many grams of carbon dioxide are created from the complete
ololo11 [35]

Answer:

<u>167.2 g</u>

Explanation:

Known

VC4H10 = 21.3

T = 0.00 C (convert to Kelvin: 273 K)

P = 1.00 atm

Unknown

m = ?g

1. <u>Write the balanced chemical equation</u>

1 C4H10 + 1O2  ----->  4 CO2 + 5 H2O

2. <u>Find the volume ratio of Carbon Dioxide to Butane </u>

1 C4H10   4 CO2  = 4 volumes CO2 / 1 volume C4H10

3.<u> Multiply by the known volume of n (butane)</u>

21.3 L C4H10  x  4 volumes CO2 / 1 volume C4H10 = 85.2 L C4H10

4. <u>Use ideal gas law</u>

PV = nRT   solve for n  ----> n = PV/RT

n= (1.00 atm) (85.2 L) / (0.0821 L atm/mol K) (273)  = 3.80 mol CO2

5.<u> Find molar mass of CO2</u>

1 C x 12 + 2 O x 16 = 44.00

6. <u>Multiply the ideal gas law solution (3.80) by molar mass CO2 (44.00)</u>

3.80 mol CO2 x 44.00 g CO2

= 167.2 g CO2

Which of the following is least likely to dissolve in the polar solvent water?
s2008m [1.1K]
<span>Like dissolves like and unlike repels like. This applies to the polarity of the solutions. Polar dissolves polar and non-polar does not mix with polar solutions. In this case, the polar substance that can mix with water. Sugar and salt can be dissolved through agitation. Oil which is nonpolar is immiscible in water. Hence answer is D. </span>

Calculate the concentration of IO−3 in a 1.65 mM Pb(NO3)2 solution saturated with Pb(IO3)2 . The Ksp of Pb(IO3)2 is 2.5×10−13 .
lara31 [8.8K]

Answer:

See explaination

Explanation:

1) Pb(NO3)2 => Pb2+ + 2 NO3-

[Pb2+] = [Pb(NO3)2] = 7.56 mM = 7.56 x 10-3 M

Pb(IO3)2 <=> Pb2+ + 2 IO3-

Ksp = [Pb2+][IO3-]2 = 2.5 x 10-13

7.56 x 10-3 x [IO3-]2 = 2.5 x 10-13

[IO3-] = 5.75 x 10-6 M ≈ 5.8 x 10-6 M

(2) [Pb2+] = 1.7 x 10-6 M

Ksp = [Pb2+][IO3-]2 = 2.5 x 10-13

1.7 x 10-6 x [IO3-]2 = 2.5 x 10-13

[IO3-] = 3.83 x 10-4 M

[IO3-]from Pb(IO3)2 = 2 x [Pb2+]

= 2 x 1.7 x 10-6 = 3.4 x 10-6 M

[IO3-]from NaIO3 = [IO3-] - [IO3-]from Pb(IO3)2

= 3.83 x 10-4 - 3.4 x 10-6

= 3.80 x 10-4 M

NaIO3 => Na+ + IO3-

[NaIO3] = [IO3-]from NaIO3

= 3.80 x 10-4 M ≈ 3.8 x 10-4 M
