why aren't granite, copper, or petroleum found everywhere on earths surface
Answers
Answer: The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.
Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.
What is earth surface ?The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.
The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.
Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.
Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

(B) Plants undergo neither photosynthesis nor cellular respiration.
(C) Plants undergo photosynthesis but not cellular respiration.
(D) Plants undergo cellular respiration but not photosynthesis.
I'll give you Brainliest.
Answers
—Evidence—
-Plants carry our both the processes, thus generating food and energy. In fact, cellular respiration is carried out continuously throughout their life, while photosynthesis is only carried out during the hours when sunlight is available.
-Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
- Plants have mitochondria and can perform cellular respiration.

which element has the highest electrical conductivity (h) (Mg) (CL) (He)
Answers
4. He
Conductivity is the measure of the ease at which an electric charge or heat can pass through a material.A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.Electrical conductivity tells us how well a material will allow electricity to travel through it.Usually metals are good conductors of electricity.1. Chlorine is a non metal thus it will have the lowest electrical conductivity.
2. As a plasma, helium's electrons and protons are not bound together, resulting in very high electrical conductivity, even when the gas is only partially ionized.
3. Hydrogen is also electrically conductive above certain temperatures.
4. Since, magnesium is a metal thus it is also electrically conductive in nature but less than hydrogen and helium.
Therefore, Helium will have the highest electrical conductivity.

Choose whether each statement is a scientific hypothesis, theory, or law. The pressure a gas exerts on a container increases as the temperature increases because the particles in the warmer gas move faster and collide with the walls of the container with more force.
Answers
Answer:
1) theory
2) law
3) hypothesis
Explanation:
edge 2021
A scientific hypothesis is a proposition that can be determined by experiments. If the gas container is heated, then the pressure inside will increase as shown by the hypothesis.
What is a scientific theory?A scientific theory is a statement that has been tested by a thorough experiment and by following the experimental procedure to evaluate the results. The increase in temperature increases pressure because particle moves rapidly shown in theory.
A scientific law is a statement that is proven true by repeated experiments. As the temperature of the gas increases the pressure also increases showing the law of the ideal gas equation.
Therefore, scientific theory, law, and hypothesis are different.

in the reaction :N2 + 3H2----2NH3 how many grams of H2 are needed to produce 1 mole on ammonia
Answers
The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.
Calculation of the number of grams:Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams
So it be like
[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]
= 1.52 g Hz
Hence, The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

A gas at 1.5 atm had pits ressure decreased to 0.50 atm producing a new volume of 750 ml what was its original volume
Answers
Answer:
The original volume of the gas is 0.001 mL
Explanation:
This easy excersise can be solved by the law for gases, about pressure and volume; the volume of a gas is inversely proportional to the pressure it exerts.
We can propose the rule by this formula:
P₁ / V₁ = P₂ / V₂
We replace data given: 1.50 atm / V₁ = 0.50 atm / 750 mL
As the rule says, that volume is inversely proportional, and the pressure was decreased, volume must be lower than 750 mL.
1.5atm / (0.5 atm / 750mL) = V₁
V₁ = 0.001 mL
