Answer: The chemical equations are given below.
Explanation:
A balanced chemical reaction follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
Single displacement reaction is defined as the reaction in which more reactive metal displaces a less reactive metal from its chemical reaction.
General equation representing single displacement reaction follows:
C is more reactive element than element A.
The reactivity of metals is judged by the series known as reactivity series. Elements lying above in the series are more reactive than the elements lying below in the series.
- 1. When solid lead metal is put in the beaker of 0.043 M
solution.
Lead lies below in the reactivity series than iron. Thus, it will not replace iron from its chemical reaction.
- 2. When solid iron metal is put in the beaker of 0.044 M
solution.
Iron lies above in the reactivity series than lead. Thus, it will easily replace lead from its chemical reaction.
Hence, the chemical equations are given above.
Delta S reaction= Delta S products- Delta S reactants
don't forget to mulitiply by coefficients
also
here is a really slow way to do it
you know the moles of gas increased
so Delta S is positive
so its B or D
then just do the units digit to see which one match up
Answer:
-
Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Everything dead would just keep piling up and up and up and nothing would ever go away! The Earth would be like a giant landfill! <span />
The number of feet the track star ran is 4921.26 feet
<h3>Conversion scale </h3>
We can convert meter to feet by using the following conversion scale:
0.3048 meter = 1 feet
<h3>How to cconvert 1500 meters to feet</h3>
The following data were obtained from the question:
- Distance (in meter) = 1500 meter
- Distance (in feet) =?
We can convert 1500 meter to feet as illustrated below:
0.3048 meter = 1 feet
Therefore,
1500 meter = (1500 meter × 1 feet) / 0.3048 meter
1500 meter = 4921.26 feet
Thus, 1500 meter is equivalent to 4921.26 feet
