Answer:

C) 4

Explanation:

The reaction :

C (s) + 2H₂ (g) ⇒ CH₄ (g)

12g 4g 16g

Hence, based on this we can say that : 2 moles of hydrogen gas are needed to produce 16g of methane.

For 32g of methane

Number of moles of H₂ = 32/16 × 2
Number of moles of H₂ = 4

A minimumenergy of 7.21x10-19 J is required to produce the photoelectric effect in chromium metal.

forsale [732]

Answer:

2.085 x 10^-20 J

Explanation:

minimum energy required to produce photoelectric effect in chromium is given as hf = 7.21 x 10^-19 J

The work function of chromium Ф = 4.37 eV = 7.00151 x 10^-19 J

The minimum energy required to eject an electron from from a chromium metal E = ?

From E = hf - Ф

substituting values, we have

E = (7.21 x 10^-19) - (7.00151 x 10^-19)

E = 2.085 x 10^-20 J

The solubility of KClO3(s) in water increases as the

algol [13]

Answer: option (1) solubility of the solution increases.


Justification:


The solubility of substances in a given solvent is temperature dependent.


The most common behavior of the solubility of salts in water is that the solubiilty increases as the temperature increase.


To predict with certainty the solubility at different temperatures you need the product solubility constants (Kps), which is a constant of equlibrium of the dissolution of a ionic compound slightly soluble in water, or a chart (usually experimental chart) showing the solubilities at different temperatures.


KClO₃ is a highly soluble in water, so you do not work with Kps.


You need the solubility chart or just assume that it has the normal behavior of the most common salts. You might know from ordinary experience that you can dissolve more sodium chloride (table salt) in water when the water is hot. That is the same with KClO₃.

The solubility chart of KlO₃ is almost a straight line (slightly curved upward), with positive slope (ascending from left to right) meaning that the higher the temperature the more the amount of salt that can be dissolved.
