Newton's second law of motion uses the formula which states that a force will cause a mass to accelerate. (f = m •

Makovka662 [10]

Newton's second law of motion can be formally stated as follows:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

This verbal statement can be expressed in equation form as follows:

a = Fnet / m

A 46.9 gram sample of a substance has a volume of about 3.5 centimeters3. It is solid at a room temperature of 23ºC. Out of the

horrorfan [7]

Answer : (C) Hafnium is the most likely identity of the given substance.

Solution : Given,

Mass of given substance (m) = 46.9 g

Volume of given substance (V) = 3.5 $Cm^{3}$

First, find the Density of given substance.

Formula used :

$Density=\frac{\text{Mass of given substance}}{\text{Voume of given substance}}$

Now,put all the values in this formula, we get

$Density=\frac{46.9 g}{3.5 Cm^{3} }$ = 13.4 g/ $Cm^{3}$

So, we conclude that the density of given substance (13.4 g/ $Cm^{3}$ ) is approximately equal to the density of Mercury and Hafnium (13.53 and 13.31 g/ $Cm^{3}$ respectively).

According to the question the substance is solid at room temperature but Mercury is liquid at room temperature. So, Mercury is not identical to the given substance.

Another element i.e, Hafnium is the element whose density is approximately equal to the given substance and also solid at room temperature. And we know that the melting point of solid is high.

So, Hafnium is the most likely element which is the identity of the given substance.

the atomic mass of magnesium is 24 daltons and the atomic number is 12. a. how many electrons does an electrically neutral magne

vekshin1

Atomic Mass will be 23 the new magnesium formed will be its isotope of magnesium.

We know that,

In stable condition

Number of electrons = Number of protons

Atomic number represents number of proton .

So, here number of proton is 12

Therefore, number of electron is 12

We know that -

Atomic mass = number of protons +Number of neutron

So if magnesium loses one neutron i.e. new number of neutron is 11

then its atomic mass changes.

New atomic mass will be

Atomic mass = $12 + 11$

Atomic mass = 23

This new element with atomic mass 23 and atomic number 12 is the isotope of magnesium.
