What Two Processes Occur At The Mid Ocean Ridge?

Answers

Answer 1

Answer:

ridge push and slab pull

Explanation:

there are two processes through to be responsible for the spreading seen at mid ocean ridges and there is some uncertainty as to which is dominant. ridge push occurs when the weight of the ridge pushes at the rest of tectonic plate away from the ridge often towards a subduction zone. hope this helped

why do astronauts on the moon seem like they're "Walking on springs" while on earth we are firmly attached to the ground

Answers

Because of the moon's considerably lower gravity. The moon's gravity is about 1/4 as strong as the earth's gravity.
Our muscles a built to carry us on the earth. The astronauts are used to walking on earth so when they push forward with their legs they tend to use the same amount of energy which is 4 times more than needed. That push causes them to rise, Newton's second law

what is rusting of iron?​

Answers

Answer:

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Unlike rust, which can flake off the surface of iron and steel objects, the layer of aluminium oxide does not flake off.

Explanation:

Rusting = oxidation reaction
Iron = reacts with oxygen and water to form hydrated iron oxide, we then start to see rust.
This prevents the metal from coming in any contact with air. Hope this helps :)

The complete combustion of acetic acid, HC2H3O2(I) to form water, H2O(I), and CO2(g), at constant pressure releases 871.7 kJ of heat per mol of acetic acid.
Write a balanced thermochemical equation if 5.0g of acetic acid will be used in the reaction.
HC2H3O2(I) + O2 --- H2O(I) + CO2(g) H= -871.7 kJ

Answers

Answer:

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Explanation:

We know that 5.0 g of acetic acid will contain, 5.0g/60 g/mol = 0.083 moles of acetic acid

Now from the reaction equation;

1 mole of acetic acid evolved -871.7 KJ of heat

0.083 moles of acetic acid will evolve 0.083 * -871.7 = -72.35 KJ

For 5.0 g of acetic acid, we can write;

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

This chemical equation represents the combustion of propane. When correctly balanced, the coefficient for water
is
16.
2.
8.
4.

Answers

Answer:

4

Explanation:

The following equation, which depicts the combustion of propane, is given in this question as follows:

C3H8 + 02 → CO2 + H2O

However, this equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product side. To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both side correlates.

The balanced equation is as follows:

C3H8 + 502 → 3CO2 + 4H2O

Therefore, the coefficient for water (H2O) after balancing the equation is 4.

The study of chemicals is called chemistry.

The correct answer is D.

The equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product sides.

To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both sides correlates.

After balancing the equation is as follows:

[tex]C_3H_8 + 50_2 → 3CO_2 + 4H_2O[/tex]

Hence, the correct answer is 4 which shows the balanced water.

Hydrazine, N2H4, and hydrogen, H2O2, have been used as rocket propellants. They react according to the equation:

H2O2 + N2H4 → N2 + H2O

a. How many moles of N2 are formed from 0.0250 moles of N2H4? (0.0250)

b. How many moles of H2O2 are required if 1.35 moles of H2O is to be produced? (0.675)

c. How many moles of H2O are formed if 1.87 moles of N2 is produced? (7.48)

Answers

Explanation:

The equation of the reaction is;

H2O2 + N2H4 → N2 + H2O

Upon balancing the reaction, we have;

N2H4 + 2H2O2 → N2 + 4H2O  

a. How many moles of N2 are formed from 0.0250 moles of N2H4?

From the equation of the reaction;

1 mol of N2H4 produces 1 mol of N2

0.0250 mol of N2H4 would produce x mol of N2

1 = 1

0.0250 = x

x = 0.0250 * 1 / 1 = 0.0250 mol

b. How many moles of H2O2 are required if 1.35 moles of H2O is to be produced?

From the equation of the reaction;

2 mol of H2O2 produces 4 mol of H2O

x mol of H2O2 produces 1.35 mol of H2O

2 = 4

x = 1.35

x = 1.35 * 2 / 4 = 0.675 mol

c. How many moles of H2O are formed if 1.87 moles of N2 is produced?

The relationship between H2O produced and N2 is;

For every 1 mol of N2 produced, 4 mol of H2O is produced

1.87 mol of N2 produced, how many moles of H2O is produced?

1 = 4

1.87 = x

x = 1.87 * 4 / 1 = 7.48 mol

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass

Answers

answer: 11,200 g

step by step explanation:

D= M/V
M= DV
M= (13.6 g/cm^3) (825cm^3)
M= 11,200 g

The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.

What is density ?

Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.

Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.

Give that, volume of the object = 825  cm³

density =  13.6 g/cm³

Mass = volume × density

m = 825  cm³ ×  13.6 g/cm³ = 11220 g

Therefore, the mass of the object is 11220 g.

- Structural formular: This shows how th atoms in te compound are connected to each other.

- Molecular formular: This shows the actual number of atoms of element present in the compound

- Empirical Formular: This is the simplest formular of a compound. It basically shows the number of atoms in simple ration to each other.

In the laboratory you dissolve 12.7 g of silver fluoride in a volumetric flask and add water to a total volume of 125. mL. What is the molarity of the solution?​

Answers

Answer:

Molarity = 2.4 M

Explanation:

Given data:

Mass of silver fluoride = 12.7 g

Volume of water = 125 mL (125 mL× 1 L /1000 mL = 0.125 L)

Molarity of solution = ?

Solution:

Number of moles of silver fluoride:

Number of moles = mass/molar mass

Number of moles = 12.7 g/ 41.98 g/mol

Number of moles = 0.30 mol

Molarity:

Molarity = number of moles of solute / volume in L

Molarity = 0.30 mol / 0.125 L

Molarity = 2.4 M

The proton number of barium (Ba) is 56. It is in Group II of the periidic table how many electrons would you expect a barium atom to contain in its outer energy level?

Answers

Answer:

A barium atom would be expected to contain 2 electrons in its outer energy level.

Explanation:

The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.

The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.

That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

A barium atom would be expected to contain 2 electrons in its outer energy level.

3. A sample of neon gas has a volume of 1.2 L at 28.5°C. What will the volume be at 125°C it the
pressure remains constant?

Answers

Answer:

1.58L

Explanation:

Given parameters:

Initial volume  = 1.2L

Initial temperature  = 28.5°C  = 28.5 + 273  = 301.5K

Final temperature  = 125°C  = 125 + 273  = 398K

Unknown:

New volume  = ?

Solution:

Volume and temperature relationship is resolved using the Charles's law.

The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the the pressure is constant".

So;

       [tex]\frac{V1}{T1}[/tex]    = [tex]\frac{V2}{T2}[/tex]  

V1 is the initial volume

T1 is the initial temperature

V2 is the new volume

T2 is the new temperature

             [tex]\frac{1.2}{301.5}[/tex]    = [tex]\frac{V2}{398}[/tex]    

              301.5V2  = 477.6
