How many moles of hydrogen gas(H2) are needed to react with 15 moles of chlorine gas

Chemistry
1 answer:
NNADVOKAT [17]3 years ago
4 0

Answer:

15 moles of hydrogen gas are needed to react with 15 moles of chlorine gas.

Explanation:

The balanced reaction is:

H₂ (g) + Cl₂ (g) → 2 HCl (g)

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of the compounds participate in the reaction:

  • H₂: 1 mole
  • Cl₂: 1 mole
  • HCl: 2 moles

Then you can apply the following rule of three:  If 1 mole of Cl₂ reacts with 1 mole of H₂, 15 moles of Cl₂ with how many moles of H₂ does it react?

moles of H_{2} =\frac{15 moles of Cl_{2} *1mole of H_{2}}{1moles of Cl_{2}}

moles of H₂= 15

Answer:

The wavelength the student should use is 700 nm.

Explanation:

Attached below you can find the diagram I found for this question elsewhere.

Because the idea is to minimize the interference of the Co⁺²(aq) species, we should <u>choose a wavelength in which its absorbance is minimum</u>.

At 400 nm Co⁺²(aq) shows no absorbance, however neither does Cu⁺²(aq). While at 700 nm Co⁺²(aq) shows no absorbance and Cu⁺²(aq) does.

Which of these describes something a civil engineer would design?
pishuonlain [190]

Answer:

<em>The correct option is B) a bridge to connect two landmasses over a stretch of water.</em>

Explanation:

A civil engineer is a person who deals with the designing and construction of infrastructure projects like the construction of roads, buildings, bridges, airports, tunnels etc. Civil engineering is one of the most oldest disciplines in engineering and it is broken into many sub-disciplines. A civil engineer might work for a private or a government-based organization. Hence, among the options mentioned in the question, the construction of a bridge is the most likely function of a civil engineer.
