1 answer:

7 0

The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be $P_{4} O_{10}$ <u>(tetra phosphorus decoxide)</u>

<u />

Chemical element symbols, numbers, and other symbols, such as parentheses, dashes, brackets, commas, plus as well as minus signs, are used to represent the chemical quantities of the atoms that make up a certain chemical compound and molecule.

It is given that the number of P atom is 4 and 10 oxygen . Decoxide mean

any oxide with ten oxygen molecules per molecule.

Typically, a molecular molecule consists of two or even more nonmetal components. Molecular compounds are characterized by employing the stem of the primary element's term plus the suffix -ide, followed by the second element. The count of atoms in a molecule is specified using numerical prefixes.

Therefore, The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be $P_{4} O_{10}$ <u>(</u><u>tetra phosphorus decoxide)</u>

A cube has the following dimensions: 7 cm x 8 cm x 10 cm and has a density of 45 g/cm3. Calculate the mass.

gizmo_the_mogwai [7]

Density = Mass / Volume
Mass = Density * Volume
Mass = 45 * 7 * 8 * 10
Mass = 25,200 grams

How many moles of gas are there in a 50. 0 l container at 22. 0 °c and 825 torr?

2.2311 moles of gas are there in a 50. 0 l container at 22. 0 °c and 825 torrs.

<h3>What is an ideal gas?</h3>

An Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.

Assuming the gas is ideal, we can solve this problem by using the following equation:

PV = nRT

Where:

P = 825 torr ⇒ 825 / 760 = 1.08 atm

V = 50 L

n = ?

R = 0.082 atm·L·mol⁻¹·K⁻¹

T = 22 °C ⇒ 22 + 273.16 = 295.16 K

We input the data:

1.08 atm x 50 L = n x 0.082 atm·L·mol⁻¹·K⁻¹ x 295.16 K

And solve for n:

24.20312

n = 2.2311 mol

Hence, 2.2311 moles of gas are there in a 50. 0 L container at 22. 0 °c and 825 torrs.

Most atoms follow the octet rule meaning they need ------ electrons to fill their valence shells. One important exception is H w

Serggg [28]

Answer:

The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.

Explanation:

All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.
