Calculate the number of oxygen atoms and its mass in 50g of CaCo3<br>​
xz_007 [3.2K]

The number of oxygen atoms = 3

Mass = 24 g

<h3>Further explanation</h3>

The formula of a compound shows the composition of the constituent elements

CaCO₃ is composed of 3 types of elements, namely Ca, C and O

The amounts of each of these elements in the compound CaCO₃:

  • Ca = 1
  • C = 1
  • O = 3

So the number of oxygen atoms = 3

mass of Oxygen :

\tt mass~O=\dfrac{3\times Ar~O}{MW~CaCO_3}\times mass~CaCO_3\\\\mass~O=\dfrac{3\times 16}{100}\times 50=24~g

Referring to the article, which of the following is associated with the use of genetic engineering to clone farm
malfutka [58]

D. All of the given statements are true in context of animal cloning.

Explanation:

Cloning is the method in which a similar genetic copy is produced.

Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.

Mostly successfully cloned animals in live are cattle,sheep,goats...

Scientists have also cloned rats,mice,rabbits,horses...

This animal cloning is used for farming by the farmers which gives acceleration in their crop production.

Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.

The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.

What is the Lewis structure for Iodide?
jasenka [17]

Answer:

In the Lewis structure for IF5 you'll need to put a total of 12 valence electrons on the Iodine atom in order to draw the Lewis structure. Remember that Iodine (I) can hold more than eight valence electrons. For the IF5 Lewis structure, calculate the total number of valence electrons for the IF5 molecule

Suppose we have a compound that is 4.330 % Li, 22.10 % Cl, 39.89 % O, and 33.69 % H2O. What is the compounds formula?
amid [387]

The  formula   of compound is   LiClO4.3H2O


      <em><u>calculation</u></em>

  • <em><u>  </u></em>find the mole  of  each element

        that is  moles for Li,Cl,O and that of H2O

  • moles = % composition/ molar mass

       For Li = 4.330/ 6.94 g/mol=  0.624 moles

             Cl=22.10/35.5=0.623  moles

           39.89/16 g/mol =2.493  moles

           H20=  33.69/18 g/mol=  1.872  moles

  • find  the mole ratio  by  dividing each moles by smallest number of mole ( 0.624 moles)

        that  is  for  Li= 0.624/0.623=  1

                             Cl= 0.623/0.623=1

                             O = 2.493/0.623 =4

                          H2O= 1.872/0.623=3

<h3>Therefore the formula=LiClO4.3H2O</h3><h3 />

Which of the following factors could you change in a system and not change its induced EMF?
krok68 [10]
The options attached to the question above are listed below:
A. Magnetic field.
B. Type of wire.
C. Velocity of the wire.
D. Length of the wire in the field.

ANSWER
The correct option is B.
The factors that determine the induced current in a system are: the number of wires in the coil, the strength of the magnetic field and speed of armature rotation [speed of cutting]. Generally, the induced electromotive force across a conductor is equal to the rate at which magnetic flux is cut by the conductor. The type of wire used does not affect the induced EMF.
