Due to thermodynamics, heat has higher energy particles and colder temperatures have lower energy particles. Heat is always transferred to lower temperatures. Energy can transfer as heat, not cold. For example, when you put ice cubes in room temperature water, the water transfers energy as heat to the ice cubes, making the cubes warmer. The two temperatures come into equilibrium. And if the water is cold, there is an absence of heat.
The answer to 12 is that she would continue moving until something stopped her, i.e gravity
the answer to 13 is gravitational force. the gravitational force is stopping the chair from moving by pulling it down creating friction
Answer:
K = 0,00000135 = 1.35 * 10^-6
Explanation:
Step 1: Data given
The equilibrium constant, K, for any reaction is defined as the concentrations of the products raised by their coefficients divided by the concentrations of the reactants raised by their coefficients. In this case, the concentrations are given as partial pressures.
The partial pressures of H2O = 0.0500 atm
The partial pressures of H2 = 0.00150 atm
The partial pressures of O2 = 0.00150 atm
Step 2: The balanced equation
2H2O(g) ⇆ 2H2(g) + O2(g)
Step 3: Calculate K
K = [O2][H2]² / [H2O]²
K = 0.00150 * 0.00150² / 0.0500²
K = 0,00000135 = 1.35 * 10^-6
<h2><em>It is True that every bronsted-lowry acid is also a lewis acid </em></h2>
Answer:
The molarity is 6, 25M
Explanation:
A solution molar---> moles of solute ( in this case, magnesium oxide) in 1 L of solution :
0,8L solution-----5 moles solute
1 L solution----x=(1 L solutionx 5 moles solute)/0,8L solution= 6,25 moles solute---> 6,25M
