balancing the eqn: 2CaO + 2H2O → 2Ca(OH)2

so two Ca(OH)2 are produced.

two things combine to form a single compound so its synthesis reaction.

ans is Two molecules of Ca(OH)2 should be produced during the synthesis reaction.

There are 2 Ca, 4 H (2*2) and 4 O (2+2) on the left hand side. So there should be the same number of atoms 2Ca and 4(O+H) on the right hand side.  The reaction is a synthesis (making something new), rather than a decomposition (destroying something).


The answer is Two molecules of Ca(OH)2 should be produced during the synthesis reaction.

How are minute and seconds are related to degrees
jekas [21]

These minutes are further divided into sixty parts called seconds. The words minute and second used in this context have no immediate connection to how those words are usually used as amounts of time. In a full circle there are 360 degrees. Each degree is split up into 60 parts, each part being 1/60 of a degree.

What is an ion? Describe and give an example.
Goshia [24]
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.

19) What is the molarity of a KOH solution if 200 ml of the solution contains 0.6 moles KOH?
zloy xaker [14]

Answer: 3M

Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute KOH = 0.6 moles

V_s = volume of solution in ml= 200 ml

Now put all the given values in the formula of molarity, we get

Molarity=\frac{0.6moles\times 1000}{200ml}=3mole/L

Therefore, the molarity of solution will be 3M.
