Answer:

A radical is a group of atoms behaving as a unit in a number of compounds where as an element is a species of atoms having the same number of protons in their atomic nuclei.

Answer:

A radical is an atom, ion, or molecule that has unpaired electrons. An element is a substance made up of the same type of atoms. To be rather brief, a radical is an atom, while an element is made up of equal atoms.

What is the [OH^+] ina solution that has a pH=4.02

lana [24]

Answer is: concentration of hydroxide ions [OH⁻] is 1.047·10⁻¹⁰ M.
pH = 4.02.
pH = -log[H⁺].
[H⁺] = 10∧(-pH).
[H⁺] = 10∧(-4.02).
[H⁺] = 9.54·10⁻⁵ M; equilibrium concentration of hydrogen cations.
[H⁺] · [OH⁻] = 1·10⁻¹⁴ M².
[OH⁻] = 1·10⁻¹⁴ M² ÷ 9.54·10⁻⁵ M.
[OH⁻] = 1.047·10⁻¹⁰ M; equilibriom concentration of hydroxide anions.

What 2 groups can carbon bond with?

pochemuha

Carbon can form four covalent bonds. Covalent bonds are chemical bonds that form between nonmetals. In a covalent bond, two atoms share a pair of electrons. By forming four covalent bonds, carbon shares four pairs of electrons, thus filling its outer energy level and achieving stability.

A sample of hydrogen gas at 1.50 atm and constant volume is heated from 0∘C to 150∘C. What will be the final pressure of the gas

Julli [10]

Answer:

2.32

Explanation:

For the resolution of the problem one of the laws of Charles - Gay Lussac must be used, in which it is stated that if a certain amount of gas is kept at a constant volume (as in this case), its pressure will be directly proportional to its absolute temperature. Mathematically, it can be written as follows:

$\frac{P}{T} = Constant$ ⇒to constant V

In the case of the statement, that we have an initial system (P₁ and T₁) and an final system (P₂ and T₂), the equation can be written:

$\frac{P1}{T1} = \frac{P2}{T2}$

It can be rearranged to clear P₂ which is what needs to be calculated, then:

$P2=\frac{P1 . T2}{T1}$

It would only be necessary to convert the temperature units from ° C to K, to have the absolute temperature values. If T (K) = t (° C) + 273.15, then:

T₁ = 0 + 273.15 = 273.15 K

T₂ = 150 + 273.15 = 423.15 K

Now, you can replace the values to the equation and calculate P₂

$P2 = \frac{1.50 atm . 423.15K}{273.15 K} = 2.3237atm$ ≅ 2.32 atm

As the statement requests the result with three significant figures and no units, the answer is that the final pressure is 2.32
