Explanation:

There will be three peaks. The relative masses of each of the peaks is shown below;

1H - 1H peak will have a mass of 2*1.00783 amu = 2.01566 amu

1H -2H peak will have a mass of 1.00783 amu + 2.01410 amu = 3.02193 amu

2H - 2H peak will have a mass of 2*2.01410 amu = 4.0282 amu

The 2H - 2H peak is the smallest while 1H - 1H peak is the largest.

Answer:

c and o

Explanation:

Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.

The pair of elements that could not react to form an ionic compound is C and O. Thus option B is correct.

Ionic compounds are formed by the electrostatic interaction of the metal atom with a non-metal. The ionic bonds are weaker bonds and are easily dissociated in the water.

The ionic compounds can be:

The pair of elements that could not react to form an ionic compound is C and O. Thus option B is correct.

Answer:

1 g

Explanation:

The following data were obtained from the question:

Original amount (N₀) = 32 g

Time (t) = 71.5 days

Half-life of phosphorus (t½) = 14.3 days

Amount remaining (N) =?

Next, we shall determine the rate of disintegration. This can be obtained as follow:

Half-life of phosphorus (t½) = 14.3 days

Decay constant (K) =?

K = 0.693 / t½

K = 0.693 / 14.3

K = 0.0485 /day

Finally, we shall determine the amount remaining as illustrated below:

Original amount (N₀) = 32 g

Time (t) = 71.5 days

Decay constant (K) = 0.0485 /day

Amount remaining (N) =?

Log (N₀/N) = Kt/2.303

Log (32/N) = 0.0485 × 71.5 / 2.303

Log (32/N) = 3.46775 / 2.303

Log (32/N) = 1.5058

Take the antilog of 1.5058

32/N = antilog (1.5058)

32/N = 32.05

Cross multiply

32 = N × 32.05

Divide both side by 32.05

N = 32 / 32.05

N = 0.998 ≈ 1 g

Thus, the amount remaining after 71.5 days is approximately 1 g.

The half-life of a radioactive substance refers to the time taken for the substance to Decay to half of its initial size. Hence, the mass of the substance left after 71.5 days is 1 gram.

After 14.3 days ;

After 14.3 × 2 = 28.6 days :

After 14.3 × 3 days = 42.9 days :

After 14.3 × 4 days = 57.2 days :

After 14.3 × 5 days = 71.5 days :

Hence, the mass of the sample left after 71.5 days would be 1 gram.

Explanation:

put it in your own words

Answer:

Ar, P, Si, Mg, Na

Explanation:

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Na>Mg>Si>P>Ar is the order of increasing atomic radius.

Elements are the simplest substances which cannot be broken down using chemical methods.

Atomic radii vary in a predictable way along or across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus we can say that helium is the smallest element, and francium is the largest.

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Hence, Na>Mg>Si>P>Ar is the order of increasing atomic radius.
