Answer: Option (b) is the correct answer.

Explanation:

As the given reaction is as follows.

          2H_{2} + O_{2} \rightarrow 2H_{2}O

So, when we decrease the temperature for this reaction then there will be decrease in kinetic energy of reactant molecules. As a result, less number of collisions will take place.

Hence, there will be decrease in rate of chemical reaction.

Thus, we can conclude that in the given reaction decreasing the temperature would also decrease the rate of reaction.

Ammonia and oxygen react to form nitrogen monoxide and water. Construct your own balanced equation to determine the amount of NO
stiv31 [10]

Answer:

NO would form 65.7 g.

H₂O would form 59.13 g.

Explanation:

Given data:

Moles of NH₃ = 2.19

Moles of O₂ = 4.93

Mass of NO produced = ?

Mass of  produced H₂O = ?

Solution:

First of all we will write the balance chemical equation,

4NH₃ + 5O₂   →   4NO + 6H₂O

Now we will compare the moles of NO and H₂O with ammonia from balanced chemical equation:

NH₃  :   NO                                   NH₃  :   H₂O

4     :    4                                          4    :      6

2.19   :    2.19                                 2.19  : 6/4 × 2.19 = 3.285 mol

Now we will compare the moles of NO and H₂O with oxygen from balanced chemical equation:

O₂  :   NO                                               O₂ :   H₂O

5     :    4                                                  5     :    6

4.93   :   4/5×4.93 = 3.944 mol               4.93  : 6/5 × 4.93 = 5.916 mol

we can see that moles of water and nitrogen monoxide produced from the ammonia are less, so ammonia will be limiting reactant and will limit the product yield.

Mass of water = number of  moles × molar mass

Mass of water = 3.285 mol × 18 g/mol

Mass of water = 59.13 g

Mass of nitrogen monoxide  = number of  moles × molar mass

Mass of nitrogen monoxide = 2.19 mol × 30 g/mol

Mass of nitrogen monoxide = 65.7 g

velikii [3]

Answer:

Explanation:

The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.

Two solid blocks are HEATED to the temperatures show. The blocks are placed so they touch. Which diagram shows the DIRECTION HEA
Setler [38]

Answer:

Heat flows from the block at high temperature to the one with lower temperature

Explanation:

The direction of heat flow is from a body at higher temperature to one with a lower temperature.

  • Temperature gradient determines the way and manner in which heat is dissipated.
  • As a system tend to increase entropy, it ensures that heat moves from hotter body to a colder body.
  • Heat movement here is by conduction as the body touches.
  • When both bodies reaches the same temperature, thermal equilibrium is established.
