Answer:
More reactant forms.
Explanation:
Given reaction is,
⇒per mole
This is an Exothermic Reaction,(ΔE=-57.3KJper mole)
We know the equilibrium point of all Exothermic reactions moves leftward and more reactant is formed at the equilibrium.
<u>Reason:</u>
As heat is being produced in the reaction the additional heat(57.3KJpermole) can be <u>thought of as a product</u> of the reaction.
So,if you increase the temperature ,you provide heat energy,
(in other words heat energy is given) and hence the concentration of the products increases.
So, with respect to LeChateliers Principle,
As the concentration of products is increased by external means,more of the reactants are produced at the equilibrium of the reaction.
Therefore amount of reactants increases as <u>more reactant forms.</u>
The kinetic energy at the top of the rock trajectory is 43.57 Joules
The kinetic energy formula and the procedure we will use is:
K.E. = 1/2 m (v*cosθ)²
Where:
- v = speed
- m = mass
- θ = angle
- Joules = Kg m²*s²
Information of the problem:
- v = 32 m/s
- m = 0.145 Kg
- θ = 40°
Applying kinetic energy formula we get:
K.E. = 1/2 m (v*cosθ)²
K.E. = 1/2 * 0.145 kg (32 m/s*cos40°)²
K.E. = 1/2 * 0.145 kg *(24.513 m/s)²
K.E. = 1/2 * 0.145 kg *600.91 m²/s²
K.E. = 87.132 kg m²/s² / 2
K.E. = 43.57 Joules
<h3>What is kinetic energy?</h3>
It is the energy possessed by a body due to its relative motion. It is usually expressed in Joules (J).

Answer:
Binding Energy = 2.24 eV
Explanation:
First, we need to find the energy of the photon of light:
E = hc/λ
where,
E = Energy of Photon = ?
h = Plank's Constant = 6.626 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of light = 400 nm = 4 x 10⁻⁷ m
Therefore,
E = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(4 x 10⁻⁷ m)
E = (4.97 x 10⁻¹⁹ J)(1 eV/1.6 x 10⁻¹⁹ J)
E = 3.1 eV
Now, from Einstein's Photoelectric Equation:
E = Binding Energy + Kinetic Energy
Binding Energy = E - Kinetic Energy
Binding Energy = 3.1 eV - 0.86 eV
<u>Binding Energy = 2.24 eV</u>
Explanation:
Radius of a charged particle is given by
r=mv / Bq
= k/ q
where k = m v / B is a constant.
i.e. more is the magnitude of charge, less is the radius.
(inversely proportional)
From the diagram r_3 > r_2 > r_1 (more the curvature, less is the radius)
( although drawing is not given i am assuming the above order, however, one can change the order as per the diagram. The concept used remains the same)
therefore, q_1 > q_2 > q_3
.
Answer:
There is an entity to which we have given the name dark energy which contributes to the total density but which we cannot detect by the usual methods.
