A 5.0-gram sample of zinc and a 50.-milliliter sample of hydrochloric acid are used in a chemical reaction. Which combination of these samples has the fastest reaction rate?(1) a zinc strip and 1.0 M HCl(aq)
(2) a zinc strip and 3.0 M HCl(aq)
(3) zinc powder and 1.0 M HCl(aq)
(4) zinc powder and 3.0 M HCl(aq)

Answers

Answer:

(4) zinc powder and 3.0 M HCl(aq)

Explanation:

First consider the equation of reaction:

Zn + 2HCl --> ZnCl_2 + H_2

1 mole of Zinc requires 2 moles of HCl for reaction.

mole of zinc = mass/molar mass = 5.0/65.38 = 0.0765 mole

0.0765 mole of zinc will require: 0.0765 x 2 = 0.1530 mole HCl

Mole of 1.0 M HCl = Molarity x volume = 1 x 0.05 = 0.05 mole

Mole of 3.0 M HCl = 3 x 0.05 = 0.15

Hence, the 3.0 M HCl is what will give the required number of mole.

Zinc in powder form will react faster compared to in strip because the former has higher surface area for reaction.

Therefore, zinc powder and 3.0 M HCl will give the fastest reaction rate.

The correct option is option 4.
The answer is Zine powder and 3.0 M HCl (aq)

Decomposition of potassium chlorate (KClO3) produces potassium chloride (KCl) and pure oxygen (O2). The balanced equation for the reaction is as follows.mc017-1.jpg
What volume of oxygen gas is released at STP if 10.0 g of potassium chlorate is decomposed? (The molar mass of KClO3 is 122.55 g/mol.)
0.914 L
1.83 L
2.74 L
3.66 L

Answers

1.    The balanced reaction would be:

2KClO3 --> 2KCl + 3O2


We are given the amount of potassium chlorate for the reaction. This will be the starting point of our calculation. 

10.0 g KClO3 ( 1 mol KClO3 / 122.55 g KClO3) (3 mol O2 / 2 mol KClO3) = 0.1224 mol O2

V = nRT/P =0.1224 mol O2 x 273 K x 0.08206 atm L/mol K / 1 atm
V=2.74 L

Answer:

third option 2.74L

A solution that is a 4 on pH scale is a

Answers

a pH scale runs from 1 to 14 with 7 being neutral.

1-6 has base like properties
8-14 has avid line properties

since this solution has a pH scale of 4.... the solution is basic
A solution that is 4 on pH scale is an acid. A pH scale is used to measure whether a solution is an acid or a base. the pH scale is numbered between 0 to 14. 7 is the neutral point of this scale. Any solution having a pH of 7 is a neutral solution. Acidity of a solution increases as the reading in the scale decreases from seven towards zero. The basic nature of the solution increases as the pH level of the solution increases from 7 towards 14. The acidic nature of a solution having pH value of 3 is ten times more acidic than a solution having pH value of 4. The same thing is same while comparing basic solutions as well.

a gas in a balloon at constant pressure has a volume of 120.0 mL at -123°C. What is the volume at 27.0°C?

Answers

The law that can be applied here is Charle’s Law which states that for a fixed mass of gas and at constant pressure, the volume is directly proportional with the absolute temperature. It is represented by the equation of V1/T1=V2/T2. Since there is no negative volume, we will change the temperature into Kelvin, (-123+273=150K) and (70+273=300K). plugging in the values, V2 = (300K)(120mL/150K) we get a volume of 240mL.

Magnesium burns with a very bright light. When the flame goes out, a White powder is left behind. what is the word equation for this reaction.

Answers

When magnesium is burned, it reacts with oxygen in air not with the fire. The fire is the energy needed for the reaction to happen. Magnesium reacts with oxygen forming magnesium oxide. The light emitted from the reaction is because the reaction produced a lot of heat.

I WILL GIVE BRAINLIEST!Pentan-2-ol was heated with an acidified solution of potassium dichromate. Name the product(s) of this reaction.
A) Pentanoid acid
B) Pentanal
C) Pentan-2-one
D) Propanoic acid and ethanoic acid

Answers

Answer:

C) Pentan-2-one

Explanation:

The product of the reaction of pentan-2-ol with acidified potassium dichromate is pentan-2-one.

Pentan-2-ol is a secondary alcohol, and secondary alcohols are oxidized to ketones by acidified potassium dichromate. The reaction is as follows:

CH3CH(OH)CH3 + K2Cr2O7 + H2SO4 → CH3COCH3 + Cr2(SO4)3 + K2SO4 + H2O

Propanoic and ethanoic acids are not products of this reaction.

Therefore, the answer is (C).
