Which of these features of Earth's crust are caused by the shifting of tectonic plates?
A
mid-ocean ridges
B
desert sand dunes
С
arctic glaciers
D
continental shelves

Answers

Answer 1
I’m pretty sure it’s A mid-ocean ridges
Answer 2

To solve this we must be knowing each and every concept related to  tectonic plates. Therefore, the correct option is option A among all the given options.

What is  tectonic plates?

The lithosphere, which includes the crust and topmost mantle, is divided into portions by tectonic plates. Numerous dangers, including volcanic eruptions, earthquakes, and tsunamis, are caused by the relative movement of tectonic plates.

Because of the makeup of the rocks inside the plates, tectonic plates can float on the mantle. This reduces their density relative to the mantle. Granite rock, which contains quartz, feldspar, as well as other relatively light materials mostly comprised of silicon and aluminum, makes up the continental crust. Mid-ocean ridges, earth's crust are caused by the shifting of tectonic plates.

Therefore, the correct option is option A.

What is the net charge of a nitrogen atom with 8 electrons

Answers

Answer:

– 1

Explanation:

From the question given above, we obtained the following:

Electron = 8

Net charge of nitrogen =.?

Nitrogen has atomic number of 7. This also means that nitrogen has 7 proton because atomic number of an element is the equal to number of protons in the atom of the element.

Thus, we can obtain the net charge of nitrogen with 8 electrons by calculating the difference between the protons and electrons of the nitrogen atom. This can be obtained as follow:

Proton = 7

Electron = 8

Net charge = Proton – Electron

Net charge = 7 – 8

Net charge = – 1

Therefore, the net charge of the nitrogen atom with 8 electrons is – 1

Why do atoms always contain the same number of electrons and protons?

Answers

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.

Answer:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

Q1.What is the mass of 5 moles Of 1.Mg 2.CaCO3 Q2. Calculate the number of atoms in 10g of Na Q3.calculate the number of molecules in 10g of NaCl Q.4.What is Avogadro's number? How many number of atoms are present in 4g of Oxygen?

Answers

Answer:

Explanation:

Q1) as we know that moles=given mass/molar mass

     mass of 5 moles of Mg is

mass =moles*molar mass

mass=5*24

mass=120 g

mass of 5 moles of CaCO3 is

mass= moles*molar mass

mass=5*100=500

Q2) number of atoms in 10 g Na

first we need number of moles of sodium

moles =mass/molar mass

moles=10/23=0.43

now we know that moles=number of atoms /avogadro number

for number of atom the formula become

number of atom=moles*avogadro number

number of atom=0.43*6.023*10^23=2.6*10^23

Q3)number of molecule in 10 g of NaCl

again we need number of moles of NaCl

moles=given mass/molar mass

moles=10/58.5=0.17

now number of molecules=moles*avogadro number

number of molecules=0.17*6.023*10^23=1.02*10^23

Q4) avogadro number is the number of particles(atoms,molecules,ions) present in one mole of a substance its value is 6.023*10^23

Q5)Number of atoms in 4g of oxygen

again we need number of moles of oxygen

moles=mass/molar mass

moles=4/16=0.25

now number of atoms=moles*avogadro number

number of atoms=0.25*6.023*10^23 =1.5*10^23

If a substance has a mass of 12.50 g and takes up 3.4 mL of space, what is the density?

Answers

Answer:

The answer is

3.68 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

[tex]density = \frac{12.50}{3.4} \\ = 3.676470588...[/tex]

We have the final answer as

3.68 g/mL

After 24 hours, she observed how many bacteria were present.
Identify the independent and dependent variables.​

Answers

Answer:

The independent variable is type of gel and the dependent variable is the number of bacteria.

Explanation:

An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable. In the plant experiment shown above, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not. The scientists change the amount of the independent variable (the fertilizer) to observe the effects on the dependent variable (plant growth). An experiment needs to be run simultaneously in which no fertilizer is given to the plant. This would be known as a control experiment. In any experiment, other factors that might affect the dependent variable must be controlled. In the plant experiment, what factors do you think should be controlled? (Hint: What other factors might affect plant growth?)

6. An alloy of iron contains 75.0% iron and 25.0% other elements. How many grams of iron are present in 150. g of the alloy?

Answers

Answer:

108.5

Explanation:

half of 150 is 75 and half of that is 32.5. Add that to 75 and you'll get your answer

112.5 g of iron is present in the alloy.

From the question given above, the following data were obtained:

Percentage of iron (Fe) = 75%

Percentage of other elements = 25%

Mass of the alloy = 150 g

Mass of iron (Fe) =?

The mass of the iron present in the alloy can be obtained as follow:

[tex]Percentage = \frac{mass of element }{total mass }\\\\[/tex]

75% = [tex]\frac{mass of Fe}{150}[/tex]

[tex]0.75 = \frac{mass of Fe}{150}\\\\[/tex]

Cross multiply

Mass of Fe = 0.75 × 150

Mass of Fe = 112.5 g

Therefore, 112.5 g of iron is present in the alloy.
