Which energy resource produces the least amount of air pollution?
coal
natural gas
oil
hydropower
Answer:
hydropowered
Explanation:
took the test
Hydropower is the energy source that produces the least amount of air pollution. Therefore, the correct option is option D.
What is energy?Energy is The capacity or ability to do tasks, such as the ability to forcefully move an object. Energy can exist in a multitude of forms and can change from one to another, including thermal, mechanical, chemical, and nuclear energy. The flow of electric charges known as electrons is what generates electrical energy.
Energy is utilised to make a wide range of goods, power transportation, and power the appliances we use to heat and light our houses. The production of electricity is the main purpose of these various energy sources. All of these many energy sources contribute to the electrical power reserve that is then distributed to various locations via high-powered lines. Hydropower is the energy source that produces the least amount of air pollution.
Therefore, the correct option is option D.

Why was Wegener’s theory of continental drift almost completely discarded?
A. It didn’t explain how continents fit together.
B. It didn’t explain how mountains formed.
C. It wasn’t supported by fossil evidence.
D. It didn’t have a mechanism for how drift occurred.
Which of the following is evidence that the continents were once part of a supercontinent called Pangaea?
A. Island Arcs
B. Deep ocean trenches
C. Glacier scrapings
D. Mid-ocean ridges
Answer:
1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
Answer:
1. D
2. C
Explanation:
1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.
2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
How many grams of Na2SO4 can be produced from 423.67 g of NaCl?
Mass of Na2SO4= 514.18 grams
Further explanationGiven
423.67 g of NaCl
Required
mass of Na2SO4
Solution
Reaction
2NaCl + H2SO4 → Na2SO4 + 2HCl
mol NaCl :
= 423.67 g : 58.5 g/mol
= 7.24
From the equation, mol Na2SO4 :
= 1/2 x mol NaCl
= 1/2 x 7.24
= 3.62
Mass Na2SO4 :
= 3.62 mol x 142,04 g/mol
= 514.18 grams
Describe what happens to a liquid's molecules as it boils and changes into a gas.
Answer:
the particels becomes loose and wild, making gas happen when it is heated up
Liquids evaporate faster as they heat up and more particles have enough energy to break away. The particles need energy to overcome the attractions between them. At this point the liquid is boiling and turning to gas.
Jimmy's Chemical reaction/ Recipe for making Grilled chese sandwiches is given below: 1 slice of cheese + 2 slices of bread = 1 Grilled chese sandwich ( mole ratio is, 1:2:1) If Jimmy has the following amounts of ingredients (reactants/ reagents) : 10 slices of cheese 30 hslices of bread Answer the questions below in your submission: a) What is the limiting reagent/reactant? b) what is the excess reactant? c) True or false? The number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.
Answer:
See explanation
Explanation:
We have been told in the question that the equation of the reaction is; 1 slice of cheese + 2 slices of bread = 1 Grilled cheese sandwich ( mole ratio is, 1:2:1) .
Then the reagents are 10 slices of cheese 30 slices of bread. It then follows that 10 slices of cheese should be combined with 20 slices of bread according to the mole ratio.
However, we have 30 slices of bread and 10 slices of cheese so cheese is the limiting reactant while bread is the reactant in excess.
Yes, the number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.

4. How many moles of H, would be
produced from 47 grams of H2SO4?
2A1 +3H,504 → Al2(SO4)3 +3H2
Answer:
0.48 moles of H₂ are produced.
Explanation:
Given data:
Number of moles of H₂ produced = ?
Mass of H₂SO₄ = 47 g
Solution:
Chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Number of moles of H₂SO₄ :
Number of moles = mass/molar mass
Number of moles = 47 g/ 98 g/mol
Number of moles = 0.48 mol
Now we will compare the moles of H₂SO₄ and H₂
H₂SO₄ : H₂
3 : 3
0.48 : 0.48
Thus, 0.48 moles of H₂ are produced.

According to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.
According to the given chemical equation, 70.906 g of chlorine gives 117 g sodium chloride, thus, 2.4 g of sodium chloride will be produced, when 2.4×70.906/117= 1.45 g of Cl₂ reacts.
Thus, according to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.
