Li2O.. Because Li is +1 and O2 is -2
hram777 [196]3 years ago
3 0

Explanation:

Atomic number of lithium is 3 with electronic distribution 2, 1. So, to attain stability lithium loses 1 electron and becomes Li^{+} ion.

Atomic number of oxygen is 8 with electronic distribution 2, 6. So, to attain stability oxygen needs to gain two electrons and thus becomes O^{2-} ion.

Therefore, a neutral molecule will have charges balanced between the combining atoms.

Hence, when lithium and oxygen atoms combine together then they will form compound Li_{2}O.

notsponge [240]

Pole

Explanation:

A magnetic pole is the point on a magnet where a magnet effect is strongest. Around a magnet, there are magnetic fields.

  • The magnetic fields are force fields that leaves the north poles and enters through the south.
  • The pole is where magnetic effects are the strongest.
  • It is around the pole that the strongest magnetic effect on a magnet or magnetic material is felt.
  • The strength of magnetic fields are strongest at the poles.

Calculate the value deltaG°​
atroni [7]

Answer:

ΔG=ΔG0+RTlnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG=ΔG0 . Under equilibrium conditions, Q=K and ΔG=0 so ΔG0=−RTlnK . Then calculate the ΔH and ΔS for the reaction and the rest of the procedure is unchanged.

A 11.97g sample of NaBr contains 22.34 % Na by mass. Considering the law of constant composition (definite proportions), how man
kap26 [50]
<h3>Answer:</h3>

2.125 g

<h3>Explanation:</h3>

We have;

  • Mass of NaBr sample is 11.97 g
  • % composition by mass of Na in the sample is 22.34%

We are required to determine the mass of 9.51 g of a NaBr sample.

  • Based on the law of of constant composition, a given sample of a compound will always contain the sample percentage composition of a given element.

In this case,

  • A sample of 11.97 g of NaBr contains 22.34% of Na by mass
  • Therefore;

A sample of 9.51 g of NaBr will also contain 22.345 of Na by mass

  • But;

% composition of an element by mass = (Mass of element ÷ mass of the compound) × 100

  • Therefore;

Mass of the element = (% composition of an element × mass of the compound) ÷ 100

Therefore;

Mass of sodium = (22.34% × 9.51 g) ÷ 100

                         = 2.125 g

Thus, the mass of sodium in 9.51 g of NaBr is 2.125 g
