Ionic  bond  are  formed  between  a   metal  and  a  non  metal  while  covalent  bonds  are  formed  between  two  non  metals.
        ionic  compounds  include
    Na-cl,  Mg-Br,  Ca-s,  Ba-F  (are  ionic  since their  bond  is  between a  metal  and  non metal)

covalent  bonds  include
 O-H,  N-O,  C-H,  F-F,  N-H ,  C-O,  F-F ( are  covalent  since  their  bond  is  between  two  non  metal

A metal pellet with a mass of 100.0 g, originally at 116°C, is dropped into a cup of water, initially at
Alina [70]

Answer:

C, 42g

Explanation:

In thermal equilibrium, both bodies (metal pellet and water) both have the same final temperature (46.3°C).

Assuming no heat is lost to surroundings,

the energy lost from metal pellet = energy gained for water

Since E = mc∆T

(energy = mass x specific heat capacity x temperature change)

mc∆T (metal pellet) = mc∆T (water)

100 x 0.568 x (116-46.3) = m 4.184 (46.3 - 23.8)

3958.96 = 94.14m

m = 42g

L and D forms of a molecule are what kind of isomers?
kotegsom [21]

Answer:

enantiomers

Explanation:

L and D stand for levorotatory and dextrorotatory respectively. A levorotatory molecule will rotate the plane of plane polarised light left and a dextrorotatory molecule will rotate the plane of plane polarised light right.  L and D molecules are non superimposable mirror image of each other. Therefore they are also known as enantiomers.

A 3.82 g piece of limestone contains 2.62 g of CaCO3
Kobotan [32]

Considering the definition of percentage by mass, the mass percentage of CaCO₃ is 68.59%.

<h3>What is mass percentage</h3>

The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.

In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

mass percentage=\frac{mass of solute}{mass of solution}x100

<h3>Mass percentage of CaCO₃</h3>

In this case, you know:

  • mass of CaCO₃: 2.62 grams
  • mass of limestone: 3.82 grams

Replacing in the definition of mass percentage:

mass percentage=\frac{2.62 grams}{3.82 grams}x100

<u><em>mass percentage= 68.59 %</em></u>

Finally, the mass percentage of CaCO₃ is 68.59%.
