How many liters of water can be formed if 1.65 liters of ethylene are consumed
alexandr1967 [171]
Ethylene Burns in the presence of O₂ to produce CO₂ and H₂O vapors;

                               C₂H₄  +  3 O₂   →   2 CO₂  +  2 H₂O

According to equation, 

22.4 L (1 mole) C₂H₄ reacts completely to produce  =  44.8 L (2 moles) of H₂O

So, 

1.65 L of C₂H₄ on complete reaction will produce  =  X L of H₂O

Solving for X,

                                  X  =  (1.65 L × 44.8 L) ÷ 22.4 L

                                  X  =  3.3 L of H₂O

What will be the effect on the solubility of BaF2 if the following changes are made: increasing temperature; adding NaF; adding
borishaifa [10]

In BaF₂ the solubility will decreases on adding NaF

the solubility will increases on adding HCl

<h3>SOLUBILITY OF BARIUM FLUORIDE</h3>
  • Increase in temperature will increase the solubility of the solid.
  • By adding NaF - decrease the solubility of BaF₂
  • By adding HCl - increase the solubility of BaF₂

<h3>BARIUM FLUORIDE</h3>
  • It is colourless solid that occur as rare mineral
  • It is corroded by moisture
  • It is used in window of IR spectroscopy

Hence the barium fluoride the solubility decreases on adding NaF and increases on adding HCl.

Rus_ich [418]

Answer:

Following are the responses to the given points:

Explanation:

Form the above-given question, it indicates that the bromate ion green ionizes in water to form a green-blue solution, therefore the before adding the HCL it indicator was in anionic from hence it is written as In^{-} therefore the HCL is mixed which the anion is protonated to give HIN

Complete this brønsted-lowry reaction placing each product by its appropriate label. hso4- + hcn
Yuri [45]

Answer : The balanced reaction is, HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-

Explanation :

According to the Brønsted-lowry concept, a substance is known as acid if it can donate a proton and as a base if it can accept a proton.

The given substance may be a molecule of an ion. The reaction of an acid with the base constitutes the transfer of a proton from acid to the base.

The balanced reaction will be,

HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-

In this reaction, HCN is an acid and is donating a proton to the base HSO_4^- and both are the reactants. H_2SO_4 is the conjugate acid of HSO_4^- and CN^- is the conjugate base of HCN and H_2SO_4\text{ and }CN^- are the products.

Hence, the balanced reaction is, HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-
