Answer:

It decreases as the concentration of products decreases.

It increases as the concentration of products increases.

Explanation:

the equilibrium reaction is

$N_{2}(g)+O_{2}(g)2NO(g)$

As per equilibrium,

a) there will be no effect of pressure change on the equilibrium as the number of gaseous molecules are same on both the side of reaction.

b) there will be no effect of addition of inert gas on the equilibrium as the number of gaseous molecules are same on both the side of reaction.

c) the reverse reaction rate can be increased by

i) decreasing the concentration of reactants

ii) increasing the concentration of products

False

Explanation:

Mendeleev was the first scientist to arrange the element in such a periodic order but there was a mistake that he arranged in increasing order of mass.
Today we use the periodic table given by Henry Mosley where atomic no is first priority

Calculate the magnitude and direction (i.e., the angle with respect to the positive H-axis, measured positive as counter-clockwi

r-ruslan [8.4K]

The graphics in the attachment is part of the question, which was incomplete.

Answer: Fr = 102N and angle of approximately 11°.

Explanation: From the attachment, it is observed that from the three forces acting on M, two are perpendicular. So to find them, we have to show their x- and y- axis components. From the graph:

Fx = 70+40-10 = 100

Fy = 40-20 = 20

Now, as the forces form a triangle, the totalforce is:

Fr = $\sqrt{Fx^{2} +Fy^{2} }$

Fr = $\sqrt{10400}$

Fr = ≈ 102N

To determine the angle requested, we use:

arctg H = $\frac{Fy}{Fx}$

arctg H = $\frac{20}{100}$

H = tg 0.2 ≈ 11°.

Plan an investigation using solid and liquid water to show that thermal energy is not the same as temperature.

algol [13]

The investigation using solid and liquid water to show that thermal energy is not the same as temperature is:

Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

<h3>What is the response to the experiment above?</h3>

The response is No, because the lake is known to have a lot more particles than the glass of water and so they will not have the same thermal energy.

Note that the temperature is seen as the an average and thermal energy is seen to be the total. A glass of water can be able to have the same temperature as what we call Lake Superior, but the lake has a lot of thermal energy due to the fact that the lake has a lot of water molecules.

So the investigation using solid and liquid water to show that thermal energy is not the same as temperature is Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

How did max planck contribute to the modern atomic theory?

Igoryamba

Answer:

Planck made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized our understanding of atomic and subatomic processes, just as Albert Einstein's theory of relativity revolutionized our understanding of space and time
