Colonialism made African colonies dependent by introducing a mono- cultural economy for the territories. It also dehumanized African labour force and traders. It forced Africans to work in colonial plantations at very low wages and displaced them from their land

Answer:

It is often necessary to start campfire with many pieces of kindling rather than large logs because it is easier to ignite smaller pieces than larger pieces. Imagine wanting to light up a pile of clothes and a small piece of a shirt. Which ignites faster? The piece of a shirt, because it is smaller and more likely to burn very quickly. Additionally, people criss-cross these tiny pieces of wood to enable more surface area and to allow more oxygen to pass through. As you know, oxygen is necessary for a flame to ignite.

Answer:

There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.

Explanation:

option (B) is right

Metals used in batteries undergo a chemical reaction with the electrolyte and free the electrons. The flow of electrons produces the electric current.

An electric battery can be described as a source of electric power containing of one or more electrochemical cells with external connections.

The positive terminal of the battery is the cathode and its negative terminal is the anode. The negative terminal can be denoted as the source of electrons that will flow via an external electric circuit to the positive terminal.

A redox reaction transforms high-energy reactants into lower-energy products, and the free-energy difference provides the external circuit as electrical energy.

Each cell of the battery contains two half-cells connected in series by an electrolyte containing metal cations. One half-cell includes an electrolyte and the negative electrode and the other half-cell includes an electrolyte and the positive electrode. Cations are reduced at the cathode, while metal atoms are oxidized at the anode.

Explanation:

1) With the advent of the quantum theory came the idea that the path of a moving electron can not be exactly determined. We can only talk about the probability of finding the electron within a given region in space.

2) Using the De Broglie's relation;

λ = h/mv

Where;

λ = wavelength

h = Plank's constant

m = mass

v = velocity

λ = 6.6 * 10^-34/2.05 x 10^7 * 7.85 x 10^3

λ = 4.1 * 10^-25 m

Answer:

3.52 x 10^24 molecules x `1mol/6.02 x 10^23 molecules = 5.85 moles of H2O.

Explanation:

Answer:

When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.

Hope this helps you out! Have a nice day! :)

Answer:

50 moles of many mango seeds = 2.107.10²⁴ mango

Further explanation

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule

With  Avogadro's number

N = number of gas particles

No = Avogadro number (6.02.10²³)

n = number of moles

n= N/No

3.50 moles of many mango seeds are comparable to

N mango seeds= 3.5 x 6.02.10²³

N mango seeds=2.107 x 10²⁴..

Answer:

5.3g of MgO would be produced

Explanation:

Based on the chemical reaction:

2Mg(s) + O₂(g) → 2MgO(s)

1 mole of Mg reacts per mole of oxygen.

To solve this question we need to convert the mass of each reactant to moles in order to find limiting reactant using the chemical equation:

Moles Mg -Molar mass: 24.305g/mol-:

3.8g Mg * (1mol / 24.305g) = 0.1563moles Mg

Moles O₂ -Molar mass: 32g/mol-:

2.1g O₂ * (1mol / 32g) = 0.0656 moles O₂

For a complete reaction of 0.0656 moles of O₂ are required:

0.0656 moles O₂ * (2 mol Mg / 1mol O₂) = 0.132 moles Mg

As there are 0.1563 moles of Mg, Mg is the excess reactant and O₂ the limiting reactant.

0.0656 moles O₂ produce:

0.0656 moles O₂ * (2 mol MgO / 1mol O₂) = 0.132 moles MgO

The mass is -Molar mass MgO: 40.3g/mol-:

0.132 moles MgO * (40.3g / mol) =

5.3g of MgO would be produced

Gravity helps show a cause and effect by demostarting how one object will have an effect on another object.

Explanation:

If you bounce a ball, it will fly back up, but it will fall down again because of gravity. The cause is GRAVITY and the effect is the ball FALLINg. Now, because o fgravity, when the ball bounces up again, it will only bounce 1/2 the hieght, having another cause and effect. As gravity pushes down on objects, the more an object is effected by it, the more presure it will have.
