All the reactions given are single displacement reactions and can only occur if the metal is more reactive than the metal in the salt. In the first equation, silver is much less reactive than sodium so no reaction occurs. Same goes for the other 2. However the last equation will occur as iron is more reactive than copper and will displace it out of solution, forming copper metal and iron nitrate. Therefore the 4th reaction will form products

Use the particle theory to explain,liquid to soild process
hjlf

The liquid to solid process  using the particle theory is as below


  • The process  that involve  change    of liquid to solid  is known as  Freezing
  • It involve  change from a high energy state to lower energy
  • The constant  temperature at  which  a liquid change to solid by giving  out heat energy is called freezing point  of the liquid
  • when  liquid are cooled  the thermal energy  of  particles  decrease.
  • The cohesive forces  between  the  particles strengthen  to such extent  that particles  can have relative motion with each other and they occupy the fixed position, thus liquid is converted to solid

Solve for y in the following problem: 5.3 x 10- (y)(2y)
weqwewe [10]

Answer:

The value of y = 5.1478

Explanation:

The linear equation is an equation obtained when a linear polynomial is equated to zero. When the solution obtained on solving the equation is substituted in the equation in place of the unknown, the equation gets satisfied.

The given equation: 5.3 x 10- (y)(2y) = 0

⇒ 53 - 2y² = 0

⇒ 2y² = 53

⇒ y² = 53 ÷ 2 = 26.5

⇒ y = √26.5 = 5.1478

Carbon dioxide is a...
Marina86 [1]

Answer: Option B) Pure Substance &

Compound

Explanation:

Carbon dioxide is a compound because it is formed when one carbon atom and two oxygen atoms chemically combined together.

C(s) + O2(g) ---> CO2(g)

Also, CO2 is a pure substance because it is natural and cannot be broken down easily or separated by physical methods.

A sample of a pure compound that weighs 60.3 g contains 20.7 g Sb (antimony) and 39.6 g F (fluorine). What is the percent compos
Volgvan

Answer:

The percent composition of fluorine is 65.67%

Explanation:

Percent Composition is a measure of the amount of mass an element occupies in a compound. It is measured in percentage of mass.

That is, the percentage composition is the percentage by mass of each of the elements present in a compound.

The calculation of the percentage composition of an element is made by:

percent composition element A=\frac{total mass of element A}{mass of compound} *100

In this case, the percent composition of fluorine is:

percent composition of fluorine=\frac{39.6 g}{60.3 g} *100

percent composition of fluorine= 65.67%

<u><em>The percent composition of fluorine is 65.67%</em></u>
