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

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-.

For a certain chemical reaction, the bond energy of the reactants is 43 kJ, and 35 kJ of energy is released. For energy to be conserved, what is the bond energy of the products?

Answers

Answer:

78kJ

Explanation:

Energy change = Energy in (reactants) - Energy out (products)

According to this question, energy is released, meaning that the reaction is EXOTHERMIC. Hence, the energy change will be negative (-) i.e bond energy of reactants is greater than bond energy of products.

Energy in = bond energy of reactants = 43kJ

Energy out = bond energy of products = ?

Energy change of exothermic reaction = -35kJ

Therefore;

-35kJ = 43kJ - x

x = 35kJ + 43kJ

x = 78kJ

The bond energy of the products is 78kJ.

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.

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

Answers

Answer:

3.1atm

Explanation:

Given parameters:

Volume of gas = 2L

Number of moles  = 0.25mol

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

Unknown:

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]  

 Now insert the parameters and solve;

         P  = [tex]\frac{0.25 x 0.082 x 298}{2}[/tex]   = 3.1atm

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

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.
