define open and closed circuit​

Answers

Answer 1

Answer:

An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.

Answer 2
Open circuit allows current to pass through
Closed circuit doesn’t allow current to pass

We can verify the properties as follows;

1) Sour taste - Put some soda on your tongue

2) Corrode metals - Put a little soda on a clean metal surface

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Does Soda show acidic properties?

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

Calcium carbonate (limestone) decomposes when heated.
Caco, + CaO + CO2

b) Calculate the volume of carbon dioxide produced if 10 grames were decomposed.​

Answers

Explanation:

Equation -

CaCO₃ → CaO + CO₂

molecular masses of -

CaCO₃ = 40+12+16×3 = 100 g/mol

CaO = 40+16 = 56 g/mol

CO₂ = 12+16×2 = 44 g/mol

Now,

If 100 g of CaCO₃ is decomposed then it produces 56 g of CaO and 44g of CO₂

Then,

If 1 g of CaCO₃ is decomposed then it produces 56/100g of CaO and 44/100g of CO₂

Now,

Here in question, 10g of CaCO₃ is decomposed

It means, It produces

56/100 × 10 = 56/10 = 5.6 g of CaO and

44/100 × 10 = 44/10 = 4.4 g of CO₂

Now,

we get that 10 g of CaCO₃ on burning produces 4.4 g of CO₂

we need to calculate volume of 4.4 g of CO₂

mole = mass/Gram molecular mass

Then,

mole = 4.4/44 = 0.1

Now,

volume = mole × 22.4 (in Litres)

= 0.1 × 22.4 = 2.24 L

Hence,

2.24 L of CO₂ will be produced when 10g of CaCO₃ decomposed.

What is an ecosystem?

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.

lonic bonds tend to form between two atoms with what characteristics?​

Answers

Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

Explanation:

Ionic bonds tend to form between two atoms with a high electronegativity difference.

Explanation:

An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compounds

So, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

The diagram above shows the distribution of speeds for a sample of N2(g)
at 25°C
. Which of the following graphs shows the distribution of speeds for a sample of O2(g)
at 25°C
(dashed line) ?

Answers

Answer:

A

Explanation:

The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.

Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.

Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.

For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

What is the chemical equation?

A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.
