Pharmacists sometimes measure medicines in the unit of "grains," where 1 gr = 65 mg. The label on a bottle of aspirin reads "Asp

viva [34]

Answer:

325mg of Aspririn

Explanation:

First you should note the information that the problem gives you:

- The bottle of Aspirin has 5gr (grains)

- 1gr(grain) = 65mg (miligrams)

Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:

-First you should put the quantity you need to convert:

$5grAspirin$

-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:

$5grAspirin*\frac{}{1grAspirin}$

-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:

$5grAspirin*\frac{65mgAspririn}{1grAspirin}$

-Finally you multiply numerators and divide by denominators:

$5grAspirin*\frac{65mgAspririn}{1grAspirin}=325mgAspririn$

Which one of these is most likely to gain electrons and which one is most likely to lose electrons? (And please explain why)

Lelu [443]

Answer:

(I). The most likely to lose electron is Rubidium

(II). The most likely to lose electron is Bromine

Explanation:

Given that,

Radium, Indium, Phosphorus, Tellurium, Bromine and Rubidium

We know that,

Metal :

They atom which to lose electron these is called metal.

When the atom loses the electron then the positive charge come on the atom.

The most likely to lose electron is Rubidium

Non metal :

They atome which is gains electron. It is called non metal.

So, we can say that, the non metal gains electron.

When the atom gains the electron then the negative charge come on the atom.

The most likely to gain electron is Bromine

Hence, This is required answer.
