Answer:
a) O²⁻ + H₂O <-----> OH⁻ + OH⁻
Acid = H₂O
Base = O²⁻
Conjugate Acid = OH⁻
Conjugate Base = OH⁻
b) HClO₄ + H₂SO₄ <-----> ClO₄⁻ + H₃SO₄⁺
Acid = HClO₄
Base = H₂SO₄
Conjugate Acid = H₃SO₄⁺
Conjugate Base = ClO₄⁻
c) NH₃ + HNO₃ <--> NH4⁺ + NO₃⁻
Acid = HNO₃
Base = NH₃
Conjugate Acid = NH4⁺
Conjugate Base = NO₃⁻
Explanation:
- Acids are molecules or ions capable of donating a proton (H⁺).
- Bases are molecules or ions that readily accept the H⁺ from acids.
- Conjugate Acids, according to the Brønsted–Lowry acid–base theory, are chemical compounds formed after the reception of a proton (H⁺) from an acid by a base.
- Conjugate Bases, Brønsted–Lowry acid–base theory, are the leftovers from when acids donate their proton (H⁺).
Answer:
The answer is: higher temperature/ more kinetic energy/ more space between particles/ higher volume
Explanation:
The osmium with a density of 22.6g/cm3 has a volume in cm3 of 0.965 cm3
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
Applying the density formula and isolating the volume (v), we get:
ρ = m/v
v = m / ρ
v = 21.8 g / 22.6g/cm3
v = 0.965 cm3
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
