Answer:
<h2>Physics</h2>
Explanation:
This definition was given by Isaac Newton.
He defined three "Laws of Motion" that describe what happens when forces act on objects
Answer:
Removing O₂, means removing one of the reactants and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Explanation:
The principle that explains how changes in temperature, Concentration and Pressure of reactants or products of a reaction at equilibrium affect the equilibrium position of the reaction is the Le Chatelier's principle.
The Principle explains that a system/process if a system/process which is at equilibrium is disturbed/perturbed/constrained by one or more changes (in concentration, pressure or temperature), the system would shift the equilibrium position to counteract the effects of this change.
Removing O₂, means removing one of the reactants (changing its concentration) and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Given parameters:
Mass of rock = 14g
Volume of rock = 12cm³
Unknown:
Density of the rock = ?
Density of a substance is the amount of substance it contains per unit volume. Mathematically, this can be expressed as;
Density =
Now simply input the parameters and solve;
Density = = 1.17g/cm³
Density of the rock that Jack has is 1.17g/cm³
