The number of energy levels to which an electron can jump depends on the amount of energy the electron possesses. Each energy level has a specific amount of energy an electron needs to have before it can be in there. So, if an electron doesn't have enough energy to be in that energy level then it won't jump to that higher level.

Answer:

amount of the energy that the electron absorbs.

Explanation:

According to Bohr's postulates, electron present in the energy levels can jump to their higher energy levels on absorbing energy and also come back to their orbital by the radiating the absorbed energy.

Thus, the number of the energy levels to which the electron can jump depends upon the amount of the energy that the electron absorbs.

What are fluids? Why are they so called?

navik [9.2K]

Answer:

Liquids and gases are called fluids because they can be made to flow, or move.

 In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container. So that they're called fluids.

Calculate the molarity of a solution of sodium hydroxide, naoh, if 23.64 ml of this solution is needed to neutralize 0.5632 g of

GuDViN [60]

The molarity of NaOH needed is calculated as follows
calculate the moles of KhC8h4O4

that is moles = mass/molar mass of KhC8h4O4(204.22 g/mol)

=0.5632g /204.22g/mol= 2.76 x10^-3 moles

write the equation for reaction

khc8h4O4 + NaOH ---> KNaC8h4O4 + H2O

from the equation above the reacting ratio of KhC8h4O4 to NaOh is 1:1 therefore the moles of Naoh is also 2.76 x10^-3 moles

molarity of NaOh = (moles of NaOh / volume ) x 1000

that is { (2.76 x10^-3) / 23.64} x100 =0.117 M

How many of the following statements about silver acetate, AgCH3COO, are true? i) More AgCH3CoO(S) will dissolve if the pH of th

shutvik [7]

Answer:

All three statements are true

Explanation:

Solubility equilibrium of silver acetate:

$AgCH_{3}COO\rightleftharpoons Ag^{+}+CH_{3}COO^{-}$

If pH is increased then concentration of $H^{+}$ increases in solution resulting removal of $CH_{3}COO^{-}$ by forming $CH_{3}COOH$ . Hence, according to Le-chatelier principle, equilibrium will shift towards right. So more $AgCH_{3}COO$ will dissolve
If $AgNO_{3}$ is added then concentration of $Ag^{+}$ increases in solution resulting shifting of equilibrium towards left in accordance with Le-chatelier principle. So less $AgCH_{3}COO$ will dissolve
Insoluble precipitate of AgOH is formed by adding NaOH in solution resulting removal of $Ag^{+}$ . So, more $AgCH_{3}COO$ will dissolve

Hence all three statements are true

1 How many moles of solute are in:

Sonbull [250]

Moles of solute for both a and b are the same = 1 mol

<h3>Further explanation</h3>

Given

a 500 cm³ of solution, of concentration 2 mol/dm³

b 2 litres of solution, of concentration 0.5 mol/dm³

Required

moles of solute

Solution

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

Can be formulated :

$\large \boxed {\bold {M ~ = ~ \dfrac {n} {V}}}$

V = 500 cm³ = 0.5 L

M = 2 mol/L

n=moles = M x V

n = 2 mol/L x 0.5 L

n = 1 mol

V = 2 L

M = 0.5 mol/L

n=moles = M x V

n = 0.5 mol/L x 2 L

n = 1 mol

The image shows two opposite forces acting on a rolling cart, what can we say is true about the effect on the forces on the cart

bonufazy [111]

Question options:

1. It cannot be determined without knowing which man is stronger.

2. The forces are unbalanced, and net force on the cart moves it to the left.

3. It cannot be determined because one man is taller than the other.

4. The forces are unbalanced, and net force on the cart moves it to the right.

Answer:

2.The forces are unbalanced, and net force on the cart moves it to the left.

Explanation:

In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.

It is because the person on the right side exerting force (50N) toward the left, rolling cart will moves to the left.
