A certain compound is made up of one phosphorus (P) atom, three chlorine (Cl) atoms, and one oxygen (O) atom. What is the chemic
yulyashka [42]

Answer: PCl₃O

Explanation:

1) The chemical formula tells the composition of a compound in terms of the ratio of number of atoms of each element that consitutes such compound.

2) You use the chemical symbol for each kind of atom (element) and subscripts to the right of each symbol to tell the number of atoms of each element.

3) For example, O₂ means two atoms of oxygen. Al₂O₃ means two atoms of aluminum and 3 atoms of oxygen.

4) Therefore, PCl₃O means a ratio 1 : 3 : 1 for phosphorus, chlorine, and oxygen.

Hence, PCl₃O is the chemical formula of your compound.

Which forces involve nonpolar molecules?
Elanso [62]
The answer is London dispersin forces and dipole-induced dipole forces.

The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction. This force is found in any compound and is the weakest atraction force between atoms or molecules.

Those temporay dipoles are not like the dipoles that form the polar molecules, because the polar molecules are the result of permanent dipoles.

Given 1kg=2.20 lbs, how many kilograms are in 125 lbs?<br> (Metric conversion)
Nadya [2.5K]

Answer:

56.82 Kg

Explanation:

Given data:

1 Kg = 2.20 lbs

Number of kilogram in 125 lbs = ?

Solution:

lbs is used for pound. lb is abbreviation of libra. It is Latin word meaning balance.

Both kilogram and pounds are units of mass. Pound is smaller unit than kilogram.

one Kg = 2.20 lbs

Number of kg in 125 lbs:

125 lbs × 1 Kg/2.20 lbs

125 lbs.Kg/2.20 lbs

56.82 Kg

Give the stoichiometric coefficient for oxygen when the following equation is balanced using the lowest, whole-number coefficien
Mademuasel [1]

Answer: 2 \cdot CH_{4} O (l)+3 \cdot O_{2}(g) \rightharpoonup 2 \cdot CO_{2}(g) + 4 \cdot H_{2}O(l)

Explanation:

Let consider that one mole of diatomic oxygen is used. So, the stoichometric can be modelled by using three variables:

x \cdot CH_{4} O (l)+O_{2}(g) \rightharpoonup y \cdot CO_{2}(g) + z \cdot H_{2}O(l)

Where x,y,z are the required variables.

Now, three equations are constructed from the number of elements involved (Carbon, Hydrogen and Oxygen):

Carbon

x=y

Oxygen

x+2=2\cdot y + z

Hydrogen

4\cdot x = 2 \cdot z

The coefficients can be found by solving the abovementioned 3 x 3 Linear System:

x = \frac{2}{3}, y = \frac{2}{3}, z = \frac{4}{3}

The whole-number coefficients are determined by multiplying every coefficient by 3, then:

2 \cdot CH_{4} O (l)+3 \cdot O_{2}(g) \rightharpoonup 2 \cdot CO_{2}(g) + 4 \cdot H_{2}O(l)
