Which quantity must be determined experimentally in order to determine the bonding atomic radius of an atom?.

1 answer:

7 0

Only by measuring the separation between the nuclei of two contacting atoms and halving that distance can one determine the radius of an atom. The illustrations show how the environment around an atom can cause it to have a varied radius, even if it is the same atom.

<h3>How can the atomic size of an element be determined?</h3>

By measuring the distance between the two atoms after two are united, we may determine the atomic size of the new molecule. The third technique for determining an element's atomic size is to create a single covalent link between two atoms and measure the space between them.

Atomic radii in the periodic table change from left to right across a row and from top to bottom along a column. Because of these two patterns, the periodic table's bottom left corner contains the biggest atoms, while the upper right corner has the smallest.

According to the law of constant composition, how many grams of oxygen does this isolated sample contain?

KatRina [158]

The Mass of oxygen in isolated sample is 8.6 g

<h3>What is the Law of Constant composition?</h3>

The law of constant composition states that pure samples of the same compound contain the same element in the same ratio by mass irrespective of the source from which the compound is obtained.

Considering the given ascorbic acid samples:

Laboratory sample contains 1.50 gg of carbon and 2.00 gg of oxygen

mass ratio of oxygen to carbon is 2 : 1.5

Isolated sample will contain 2/1.5 * 6.45 g of oxygen.

Mass of oxygen in isolated sample = 8.6 g

In conclusion, the mass of oxygen is determined from the mass ratio of oxygen and carbon in the compound.

If you added 15,000 calories to 2.0 L of water that was at 25.0 degrees C, what temperature would it be at when you finished?

rewona [7]

<u>Answer:</u>

<em>When we finish, the temperature would be 32.5℃</em>

<u>Explanation:</u>

Density of water = mass/volume

So,

Mass of water = Density × Volume

$\\\\$=1.0 \times 2.0 L$\\\\$=1.0 \frac{g}{m L} \times 2000 m L$\\\\$\quad=2000 g$$

$Q=m \times c \times \Delta T$

where

$\Delta T$ = Final T - Initial T

Q is the heat energy in calories

c is the specific heat capacity (for water 1.0 cal/(g℃))

m is the mass of water

plugging in the values

$15000 \mathrm{Cal}=2000 \mathrm{g} \times 1.0 \frac{\mathrm{cal}}{\mathrm{g}^{\circ} \mathrm{C}} \times \Delta T$

$\\$\Delta T=\frac{15000 \mathrm{cal}}{2000 \mathrm{g} \times \frac{1.0 \mathrm{cal}}{g^{\circ} \mathrm{C}}}$\\\\$\Delta T=7.5^{\circ} \mathrm{C}$$

Final T = ∆T + Initial T

= 7.5℃ + 25℃ = 32.5℃ (Answer).
