Describe in detail how you would determine the density of a potato that is too large to fit into a graduated cylinder. (Hint: Th
Mnenie [13.5K]

Answer:

The density of a potato is \dfrac{M}{V'}

Explanation:

Given that,

A potato that is too large to fit into a graduated cylinder.

Let us consider the mass of potato is M and volume of entire potato is V'.

The volume of water is V.

We know that,

Density :

The density is equal to the mass divided by volume.

In mathematically,

\rho=\dfrac{m}{V}

Where, m = mass

V = volume

We need to calculate the volume of potato

Using formula for volume

V'=V''-V

Where, V' = volume of potato

V''=Volume of combine water and potato

V = volume of water

We need to determine the density of a potato

Using  formula of density

Density\ of\ potato=\dfrac{Mass\ of\ potato}{volume\ of\ entire\ potato}

Put the value into the formula

\rho=\dfrac{M}{V'}

Hence, The density of a potato is \dfrac{M}{V'}

How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

What was concluded about the structure of the atom as the result of the gold foil experiment? 1)a positively charged nucleus is
motikmotik
It's 2) a positively-charged nucleus is surrounded by mostly empty space (aka Rutherford's Model). 

Most of the atom's mass is inside the nucleus (which contains protons [+] and neutrons [0 charge]), while the electrons [-] "float" around the nucleus like clouds. This is why it's said that the atom is 'mostly empty space'.
