Which of the following correctly shows the flow of energy in a food chain

Answers

Answer 1

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers, than finally after death of an organism, to decomposers

Answer 2

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

What is food chain?

The sequence of events within an ecosystem known as a "food chain" occurs when one live organism eats a different organism, which is then eaten by a larger organism. A food chain is created by the transfer of energy as well as nutrients from one creature to another at various trophic levels. A food web is comprised of numerous linked food chains.

The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers from the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain.  A food web and a food chain are similar, but a food web seems far bigger. The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

Therefore, the direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

Astronomers observed that the orbit of Uranus was not uniform. Therefore, they hypothesized the existence of another planet. This is an example of scientific investigation being led by _____.

Inductive Reasoning
Deductive Reasoning

Answers

Answer:

This is an example of scientific investigation being led by inductive reasoning.

Explanation:

Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.

The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.

How many molecules of CO2 are contained in 4.40g of CO2

Answers

Answer:

6.02 x 10²²molecules

Explanation:

Given parameters:

Mass of CO₂  = 4.4g

Unknown:

Number of molecules in CO₂  = ?

Solution:

To find the number of molecules in the given mass, we have to find the number of moles in the compound first;

   Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of CO₂  = 12 + 2(16) = 44g/mol

Insert the parameters and solve;

   Number of moles  = [tex]\frac{4.4g}{44g/mol}[/tex]   =  0.1mol

  1 mole of a substance contains 6.02 x 10²³molecules

  0.1 mole of CO₂ will contain 0.1 x 6.02 x 10²³molecules

                                                 = 6.02 x 10²²molecules

Determine which equations you would use to solve the following problem: Calculate the amount of heat needed to change 20.0 g of ice at -10.0°C to water at 89.0°C.

Answers

Answer:

Q = 4019.4 J

Explanation:

Given data:

Mass of ice = 20.0 g

Initial temperature = -10°C

Final temperature = 89.0°C

Amount of heat required = ?

Solution:

specific heat capacity of ice is 2.03 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT =  89.0°C - (-10°C)

ΔT = 99°C

Q = 20.0 g ×2.03 J/g.°C × 99°C

Q = 4019.4 J

Answers

Answer: Carbon

Explanation:

electronegativity decreases when you go down a column

The study of chemical bonds is called chemistry.

The correct answer is carbon.

The more negative charge present on an atom shows the electronegativity.

The attraction of the nucleus to the proton is also referred to as electronegativity.

The smaller the radius more the electronegativity.

Hence, the correct answer is Carbon as it has fewer atoms and a smaller radius.

When David reacts 13.8 grams of hydrogen gas with excess oxygen, 87.0 grams of water are formed. Calculate his percent yield of water.

Answers

Percent yield = 70%

Further eplanation

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

2H₂ (g) + O₂ (g) → 2H₂O (g)

mass of H₂O (theoretical) :

[tex]\tt mass=mol\times MW(mol~ratio~H_2O\div H_2=2\div 2)\\\\mass=(\dfrac{2}{2}\times \dfrac{13.8}{2})\times 18~g/mol\\\\mass=124.2~g[/tex]

Note: The correct question is given below:

Which best describes why NH4+ can form an ionic bond with Cl-?

Its outermost shell gains one or more electrons from Cl-.

Its positive charge is attracted to the negative charge of Cl-.

It has a negative charge that is spread over the entire ion.

It has a nitrogen atom that is strongly attracted to Cl-.

Its positive charge is attracted to the negative charge of Cl-.

Explanation:

An ammonium ion is a positively charged ion which is composed of a molecule of ammonia and a hydrogen ion which are in a coordinate covalent bond due to the lone pair of electrons of the nitrogen atom in the molecule ammonia. The chloride ion however, has an extra electron which gives it a negative charge.

An ionic bond is formed between two oppositely charged ions by a transfer of electrons from one atom to another. It usually occurs between non-metals and metals. However, that formed between ammonium ion and chloride ion is between non-metals entirely.

Due to electrostatic attraction between the oppositely charged ions, an ionic bond is formed between ammonium ion, NH4+, and chloride ion, Cl-.

What is the pressure inside a 2.0 L bottle filled with 0.25 mol of carbon dioxide gas at 25 °C?

Answers

3.1atm

Explanation:

Given parameters:

Volume of gas = 2L

Number of moles  = 0.25mol

Temperature  = 25°C = 25 + 273  = 298K

Pressure of the gas = ?

Solution:

To solve this problem, we use the ideal gas equation.

This is given as;

       PV  = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas  constant  = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

          P  = [tex]\frac{nRT}{V}[/tex]
