How many atoms are in 2.5 moles of Br?

Chemistry
1 answer:
Illusion [34]3 years ago
6 0

The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*1026 atoms in a liter of water. Now we know enough to answer your question.

Hope this helps

Which of the following statements is false concerning the formula of a compound?
aalyn [17]

Answer:

B. The number of atoms in a molecular formula is always greater than the number of atoms in an empirical  formula.

Explanation:

It is not always true that the number of atoms in a molecular formula is always greater than the number of atoms in an empirical formula.

The chemical formulae of a compound are of two main types;

  • The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio.
  • The molecular formula shows the actual ratio of the atoms in a compound.

Sometimes the number of atoms in the molecular and empirical formula can be the same.

Also, the number of atoms in the molecular formula is always greater than that of the empirical formula when they are not the same.

how would you write equation to show how buffers H2CO3 and NaHCO3 behave when (a) HCl is added and (b) NaOH is added.
Vlad1618 [11]
<span>H2CO3 <---> H+ + HCO3-
NaHCO3 <---> Na+ + HCO3-

When acid is added in the buffer, the excess H+ of that acid reacts with HCO3- to form H2CO3, and due to this NaHCO3 dissociates into HCO3- to attain the equilibrium. and hence there is no net effect of H+ due to pH remain almost constant. when a base is added to the buffer, the OH- ion of base react eith H+ ion present in buffer, then to attain equilibrium of H+ ion, the H2CO3 dissociates to produce H+ ion, but now there is the excess of HCO3- due to which Na+ ion react with them to attain equilibrium of HCO3-. hence there is again no net change in H+ ion due to which pH remain constant.....</span>
