What mass of oxygen can be obtained from heating 258.77 g of potassium chlorate?

Chemistry
1 answer:
Taya2010 [7]4 years ago
6 0

Answer:

101.35 g

Explanation:

The balanced equation for the reaction is:

2KClO3 ----> 2KCl  + 3O2

So 2 moles of KClO3 produces 3 moles of Oxygen

Using the molar masses:

245.09 g KClO3 produces 95.994 g of  oxygen.

258.77 g produces 95.994 * 258.77 / 245.09 = 101.35 g (answer).

The following is the reaction showing the complete neutralization of calcium hydroxide (a base) with phosphoric acid:
vodka [1.7K]

9.17 milliliters (mL) of the acid are needed to completely neutralize the base in this reaction.

<h3>What is a neutralization reaction</h3>

A neutralization reaction is a reaction between an acid and a base to produce a salt and water only.

The process of reacting given volume of acids or bases to determine the concentration or volume of either the acid or base required for neutralization is known as titration in volumetric analysis.

The formula to determine the volume of the acid required is given below:

\frac{C_{a}V_{a}}{C_{b}V_{b}} = \frac {N_{a}}{N_{b}}

where V_{a is the volume of acid required

V_{a} = \frac {C_{b}V_{b}N_{a}}{C_{a}N_{b}}

Concentration of base, Cb = (3.51/74)/0.75 = 0.063 M

Vb = 50. 0 mL

Ca = 0.229 M

Na = 2

Nb = 3

Va = (0.063 * 50 * 2)/(0.229 * 3)

Va = 9.17 mL

In conclusion, the volume of the acid is determined from the concentration, volume and mole ratio of the reaction.

What happens when uranium-238 absorbs a neutron?
Usimov [2.4K]

Answer:

B. It becomes plutonium-239.

Explanation:

When uranium  - 238 absorbs a neutron, it creates and becomes plutonium - 239 atom.

 This is a nuclear fission process in which a radioactive nucleus is bombarded with a neutron:

  ²³⁸₉₂U    +     ¹₀n   →      ²³⁹₉₂Pu

The plutonium produced is not stable and it immediately disintegrates further.

A ball has a mass of 10grams and displaces 12mL of water will the ball sink or not
Over [174]

Answer:

The ball will not sink

Explanation:

Mass of ball = 10g

Volume of water = 12mL

= 12 cm³

Density of ball = mass/volume

= 10/12

= 0.83g/cm³

Density of water = 1g/cm³

Density of ball < Density of water

(Correct me if i am wrong)
