The answer to this question would be: 10132 mm= 33.2 ft
In this question, the density of mercury is 13.6 times of water which mean the mercury mass is also 13.6 times more than water. The pressure is directly influenced by mass, so the water height should be much higher than mercury. The calculation should be: 745mm * 13.6/1= 10132 mm= 33.2 ft
A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
Answer:
The answer is false.

Answer : The correct option is, (C) 6
Explanation :
Oxidation-reduction reaction : It is a reaction in which oxidation and reduction reaction occur simultaneously.
Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.
The given unbalanced chemical reaction is,
Half reactions of oxidation and reduction are :
Oxidation : ......(1)
Reduction : .......(2)
In order to balance the electrons, we multiply equation 1 by 2 and equation 2 by 3, we get:
Oxidation : ......(1)
Reduction : .......(2)
The overall balanced chemical reaction will be:
From this reaction we conclude that the electrons are getting transferred from iron to iodine and the number of electrons transferred are 6 electrons.
Hence, the correct option is, (C) 6
