Single and double replacement reactions practice WS CuCl2 + F2 » CuF2 + Cl2

Chemistry
1 answer:
Lapatulllka [165]3 years ago

CuCl2+F2—>CuF2+Cl2.
This is a single replacement because there is one compound and one element. Picture Cu as ‘A’ Cl2 as ‘B’ and F2 as ‘C.’ So AB+C—>AC+B. A and B “broke up” and that resulted to A going with C to create the compound CuF2 leaving Cl2 alone.

From the standards of the conversions of units:
1 in^3 = 0.01638 liters

To convert 320 in^3 into liters, we will simply use cross multiplication as follows:
displacement = (320 x 0.01638) / 1
                      = 5.2416 liters

What is the most likely result of the pollution of a fresh water resource?
Troyanec [42]

Answer:

Loss of biodiversity in the wetlands.

Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.

Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.

Solution A has a pH of 3 and solution Z has
igor_vitrenko [27]
PH of a solution is -ln[H3O+] so,in case of A pH=3 or,-log[H3O+]=3 or,[H3O+]=10^-3 in case of B pH=6 pr,-log[H3O+]=6 or, [H3O+]=10^-6 so,hydronium ion concentration in solution A /the hydronium ion concentration in solution Z =10^-3/10^-6 =1000 2) Ca(OH)2+2 HNO3=Ca(NO3)2+2 H2O so the answer is 2.
