Formaldehyde (h2co) reacts with oxygen to form co2 and h2o. how many moles of co2 will be produced from reacting 2 moles of h2co
bogdanovich [222]
Answer:
            2 mol of CO₂

Solution:

The reaction is as follow,

                              H₂CO  +  O₂     →     CO₂  +  H₂O

According to this equation,

                         1 mole of H₂CO produces  =  1 mole of CO₂
So,
                   2 moles of H₂CO will produce  =  X moles of CO₂

Solving for X,
                      X  =  (2 mol × 1 mol) ÷ 1 mol

                      X  =  2 mol of CO₂

What happens to the reaction c2h6 + 137 kj when the temperature of the reaction is increased?
Solnce55 [7]

The answer is it shifts right. This could be explained by Le Chatelier's principle. It states that that when a system experiences a commotion (such as absorption, temperature, or heaviness variations), it will answer to reinstate a new equilibrium state. This just means that if there is an energy added, the reaction is trying to remove it again by going to the right.

Click the "draw structure" button to launch the drawing utility. under certain reaction conditions, 2,3−dibromobutane reacts wit
REY [17]

Answer:

Explanation:

According to this. Let's analize the possible products a, b and c.

First, the problem states that we have 2 eq. of base, For this case, let's assume it's KOH. Now, As we are doing a reaction with base, means that this reaction can only take places under conditions of SN2 and E2, a fast reaction that is taking place in only 1 step.

With this in mind, let's analyze product a. This states that it has two sp hybridized carbon, in other words, a triple bond between two carbons. So the product is with no doubt, an alkyne.

Product b has only one sp hybridized carbon, which means that this carbon should cannot be an alkyne because we need two carbon atoms. The only way to have one atom of C sp hybridized, is with two double bonds, so product b would have to a alkene with two double bonds.

Product c do not have sp hybridized carbon, therefore, it only has two double bonds in two different Carbon atoms, so it's another alkene with two double bonds, but in two different atoms of carbon.

Picture attached show the product a, b and c. Hope this can help

How does a catalyst increase the rate of a reaction?
Norma-Jean [14]

Answer:

C) It provides a lower activation energy for the reaction is the correct answer.

Explanation:

  • A catalyst increases the rate of the chemical reaction by lowering the activation energy for a reaction.
  • Catalyst is used to increase the reaction rate, it remains unchanged in the chemical reaction and it does not change the equilibrium constant.
  • Activation energy is a minimum amount of energy required to initiate the reaction.
