Answer:
H₂SO₄
Explanation:
A Brønsted acid is a proton donor. It loses protons.
This equation may be easier to understand if we write it ionically.
We see that the H₂SO₄ has lost two protons to become SO₄²⁻, so it is a Brønsted acid.
In Thompson's model, an atom is made of protons and electrons. Protons carry simplest positive charge, while electrons carry simplest negative charge thus being the simplest negative particle in an atom.
Depends if the reaction is endo or exo thermic
Endothermic reaction
Increasing the temperature will shift the equilibrium to the right-hand side of the equilibrium. to oppose the change in temperature.
Exothermic reaction
Increasing the temperature will shift the equilibrium to the left-hand side of the equilibrium. to oppose the change in temperature.
Hope that helps
None. Ammonium has no <span>π bonds at all so it can't have any resonance. </span>
The correct answer is option A.
D = M/V
The density of a substance is the ratio of its mass to its volume.
Density = mass / volume
or D = M/V
The unit of density is gram per milliliter or g/ml, when mass is expressed in gram or g and the volume is expressed in milliliter ml.
If we know the mass and volume of a substance we can calculate its density using the formula for density.
