All of the following statements are true except:

Schist is an example of metamorphic rock.
Metamorphic rocks are formed under heat and pressure.
All metamorphic rocks come from parental rocks.
Metamorphic rocks can also be formed in ocean floors.

Answers

Answer:

Metamorphic rocks can also be formed in ocean floors.

Explanation:

The ocean floor is made up predominantly of basalts and are derived by the cooling an solidification of magma in this environment.

The ocean floor is made up primarily of igneous rocks and some sediments that have been deposited from the surface. Also, materials from deep within the subsurface can reach the ocean floor where they cool and solidify to form igneous rocks. Schists are examples of metamorphic rocks as well as gneiss.

How does energy change matter?

Answers

Answer:

Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

The double replacement reaction

Further explanation

Given

Reaction if Na₂S + HCl

Required

Type of reaction

Solution

The double replacement reaction occurs when there is a displacement of the cations and anions of the reactants involved in the reaction to form two new compounds.

The general formula for this reaction :

AB + CD ⇒ AD + CB

At the bottom of the reaction, it is shown the number of atoms of each compound in the reactants and products which indicates the application of the law of conservation of mass, that the number of atoms in the reactants will be the same as the number of atoms in the product, so the reaction is said to be in a balanced state.

Which type of wave is shown in the image?

Answers

The answer will be a semestic wave

The type of wave is shown in the image is transverse wave and the correct option is option B.

What are Transverse waves?

A transverse wave is a wave in which particles of the medium vibrate at right angles, or perpendicular, to the direction that the wave travels.

Transverse waves commonly occur in elastic solids, oscillations, in this case, are the displacement of solid particles from their relaxed position, in the direction perpendicular to the propagation of the wave.

Transverse waves can travel through empty space as electromagnetic waves or be mechanical waves.

Therefore, The type of wave is shown in the image is transverse wave and the correct option is option B.

if input energyis 100J and useful is 70J what is the waste energy

Answers

Answer:

waste energy = 30 J

Explanation:

Given that.

Input energy = 100 J

Useful energy = 70 J

We need to find the amount of waste energy.

Waste energy = total energy - used energy

= 100 J - 70 J

= 30 J

Hence, 30 J of energy is waste energy.

Answers

The law of conservation of mass is directly represented in a balanced chemical equation.

What is the law of conservation of mass?

In chemistry, the law of conservation of mass says that in a closed or isolated system, matter cannot be created or destroyed in a chemical reaction.

For example: If we burn wood, the mass of ashes and gases is equal to the mass of wood before burning.

Thus, the Law of conservation of mass represent a balanced chemical equation.

M
Shift it to the left toward the reactants.
Pr
Equally create more products and reactants.
Da
Ро
It would have no effect.

Answers

Answer:

Shift it to the left toward the reactants

Explanation:

The direction of movement of a reaction at equilibrium has been explained by a man called HENRY LOUIS in his principle. According to this principle, a reaction will shift in response to a stress on equilibrium. The stress can either be effects of temperature, pressure, concentration etc on the reaction equilibrium.

- An addition of a reactant or product will cause the reaction to shift towards the opposite direction of the substance added. For example, in this question, the following reaction was given:

A + B ----> C + D

C is a product, meaning that if more of product C were added to this reaction, the reaction will shift towards the left (reactant side) because there are now more products. In other words, the reactants will be favored if there is an increase in the concentration of the products.

Answer:

Number of moles = 0.51 mol

Explanation:

Given data:

Mass of CO₂ = 22.4 g

Number of moles = ?

Solution:

Number of moles of CO₂:
