The collision of oceanic plates and any other plates in which the oceanic plate slides beneath the other plate creates the biggest earth quakes. Most of these earth quakes occur beneath the sea or oceans and can cause volcanic eruptions as well. Tsunami is another oceanic event that occurs due to earth quakes occurring due to shifting of plates beneath the sea.

In an ecosystem, the  physical characteristics of an organism are genetically passed down  from one generation to another.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explanation:

Using Charles law;

V1/T1 = V2/T2

Convert your temperatures to kelvin;

20+273=298k

60+273=333k

Then put the values the formula stated above

300/333 = V2/298

Answer:

0.664 g are formed by the reaction.

Explanation:

First of all, we determine the reaction:

Mg + CO₂  →  MgO  + CO

We need to determine the moles of the CO₂ by the Ideal Gases Law.

We convert to L, the volume → 400 mL = 0.4L

T° → 23°C + 273 = 296K

P . V = n . R .T

n = P . V / R .T

n = (1 atm . 0.4L) / (0.082 . 296K) → 0.0165 moles

Moles of Mg → 2.5 g . 1mol / 24.3g = 0.103 moles

As ratio is 1:1, CO₂ is the limiting reactant.

For 1 mol of Mg, we need 1 mol of gas

Then, for 0.103 moles of Mg, we need 0.103 moles of gas, but we only have 0.0165 moles.

If we see the product side, ratio is also 1:1

0.0165 moles of CO₂ must produce 0.0165 moles of MgO.

We convert the moles to mass → 0.0165 mol . 40.3 g /1mol = 0.664 g

non-Metals:

Nitrogen.

Oxygen.

Helium.

Sulfur.

Chlorine.

Explanation/Answer:

Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.

Answer:

Answer:

If nitrogen = 30.4% then oxygen = 100-30.4 = 69.6%

divide each % value by atomic mass

N = 30.4/14 = 2.17

O = 69.6/16 = 4.35

Divide each y smaller:

N = 2.17/2.17 = 1

O = 4.35/2.17 = 2

Explanation:

"The empirical Formula will be [tex]NO_{2}[/tex]."

What is empirical formula?

In chemistry, an empirical formula is the simplest thought of the entire number quantity of atoms in a molecule.

It is given that N = 30.4%.

The % of O can be determined as: 100-30.4%= 69.65.

Now, after dividing % value with atomic mass, we get.

Mass of  N= 14 and Mass of O = 16.

N= 30.4/14= 2.17

O = 69.6/ 16= 4.35

It can be seen that N has less number as compared to O . So, divide each with 2.17.

N= 2.17/2.17 = 1

O = 4.35/2.17=2

So the empirical formula will be [tex]NO_{2}[/tex].

Answer:

124g  

Explanation:

The concept stoichiometry is used here to determine the mass of Na₂O. The grams of Na₂O required to produce 1.60 x 10² grams of NaOH is  124 g.

The stoichiometry is an important concept of chemistry which help us to use the balanced chemical equation to calculate the amounts of reactants and products. The stoichiometric coefficient is the number of molecules that can participate in the reaction.

The balanced equation is:

Na₂O + H₂O → 2NaOH

1 mole of Na₂O is required to react with 1 mole of  H₂O to give 2 moles of NaOH.

62 g of Na₂O produces 80 g of NaOH.

1 g of NaOH is produced from 62/80 g of Na₂O .

1.6 × 10² g of NaOH will require 62 × 1.6 × 10² g / 80 g of Na₂O = 124 g Na₂O

Thus the grams of Na₂O required to produce 1.6 × 10² g of NaOH is 124 g.

Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.

The statement that represents a distinguishing difference between rocks and minerals is as follows:

Thus, the correct option for this question is B.

A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.

Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.

A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.

Therefore, the correct option for this question is B.

Answer:  1.505 * 10^24 atoms

========================================================

Work Shown:

1 mole = 6.02 * 10^23 atoms

2.5*(1 mole) = 2.5*(6.02 * 10^23 atoms)

2.5 moles = (2.5*6.02) * 10^23 atoms

2.5 moles = (15.05) * 10^23 atoms

2.5 moles = (1.505 * 10^1) * 10^23 atoms

2.5 moles = 1.505 * (10^1*10^23) atoms

2.5 moles = 1.505 * 10^(1+23) atoms

2.5 moles = 1.505 * 10^24 atoms

This is true for any element. This value is an approximation since there are roughly 6.02 * 10^23 atoms in 1 mole of any element.

Explanation:

A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.

Answer:

A. Enthalpy of the reaction

Explanation:

A Thermochemical equation is a balanced stoichiometric chemical equation that indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by ΔH, a this term which stands for the enthalpy change, ΔH.

The Enthalpy of Reaction or Heat of Reaction is the amount of energy in the form of heat transferred during a chemical reaction that occurs at a constant pressure. It is useful for calculating the amount of energy per mole either released or produced in a reaction, therefore is unit is kJ/mol.

In a reaction where energy is absorbed by the reactants during the formation of products, ΔH is positive. On the other hand, in a reaction where energy is released by the reactants during the formation of products, ΔH is negative.

The enthalpy change, ΔH of reactions are determined experimentally under standard conditions of 1 atm and 25 °C (298.15K). Enthalpy can be measured experimentally through the use of a calorimeter. A calorimeter is an isolated system which has a constant pressure and in which heat loss to the surroundings is minimal.
