Answer:

The smallest tiny particles of matter which can't be divided further is called atom, i.e., an atom is the smallest building block of matter. For example: Sodium (Na), Hydrogen (H), Oxygen (O), etc.

The smallest particle of a chemical element that can exist.

------An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. ... The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons. A proton is positively charged.

Liquid octane (CH) has a density of 0.7025 g/mL at 20 °C. Find the true mass (murue) of octane when the mass weighed in 18 air i

Goshia [24]

Explanation:

According to Buoyance equation,

m = $[m' \times \frac{1 - \frac{d_{a}}{d_{w}}}{1 - \frac{d_{a}}{d}}]$

where, m = true mass

m' = mass read from the balance = 17.320 g

$d_{a}$ = density of air = 0.0012 g/ml

$d_{w}$ = density of the balance = 7.5 g/ml

d = density of liquid octane = 0.7025 g/ml

Now, putting all the given values into the above formula and calculate the true mass as follows.

m = $[m' \times \frac{1 - \frac{d_{a}}{d_{w}}}{1 - \frac{d_{a}}{d}}]$

= $[17.320 g \times \frac{1 - \frac{0.0012 g/ml}{7.5 g/ml}}{1 - \frac{0.0012 g/ml}{0.7025}}]$

= $17.320 g \times 0.999850$

= 17.317 g

Thus, we can conclude that the true mass of octane is 17.317 g.

How is ionic radius<br> measured?

worty [1.4K]

Answer:

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. The type of atomic radius being measured here is called the metallic radius or the covalent radius depending on the bonding.
