If enough heat was REMOVED from B, it would change into ____________.

Answers

Answer 1

Answer:

If enough heat was REMOVED from B, it would change into A.

An exothermic reaction is a reaction that releases energy, this energy is usually in the form of heat. An endothermic reaction is a reaction that absorbs energy to take place.

To bring molecules together requires the release of energy, that is, an exothermic reaction.

Thus, if heat were removed from B, it would turn into A, with molecules closer together, in the solid state.

a mixture of oxygen, hydrogen, and nitrogen gases exerts a total pressure of 282 kpa. if the partial pressures of oxygen and hydrogen are 110 kpa and 106 kpa respectively, what is the partial pressure exerted by nitrogen?

Answers

Answer : The partial pressure of $N_2$ is, 66 Kpa

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

$P_T=p_(N_2)+p_(O_2)+p_(H_2)$

where,

$P_T$ = total partial pressure = 282 Kpa

$P_(N_2)$ = partial pressure of nitrogen = ?

$P_(O_2)$ = partial pressure of oxygen = 110 Kpa

$P_(H_2)$ = partial pressure of hydrogen = 106 Kpa

Now put all the given values is expression, we get the partial pressure of the nitrogen gas.

$282Kpa=p_(N_2)+110Kpa+106Kpa$

$p_(N_2)=66Kpa$

Therefore, the partial pressure of $N_2$ is, 66 Kpa

pressures oxygen and hydrogen + pressure nitrogen

110 Kpa + 106 Kpa = 216 Kpa

Partial pressure:

total pressure - exerted by nitrogen:

282 Kpa - 216 Kpa

= 66 Kpa

A force of 1 700 N is applied to a 1 300 kg car. what is the magnitude of acceleration of the car?

Answers

Hello!

Answer:

$\Large \boxed{\sf 1.30 m/s^2}$

Explanation:

→ The force applied to an object is equal to:

$\sf a = F / m$

Where:

- a is the acceleration

- F is the force

- m is the mass

→ So, the acceleration of the car is equal to:

$\sf a = F / m \n\n= 1700 N / 1300 kg\n\n \approx 1.30 m/s^2$

Conclusion:

The acceleration of the car is 1.30m/s².

Explanation:

acceleration is directly proportional to the force and inversely proportional to the mass of the object

a=f/m

=1700/1300

Which term describes this reaction? CH3Br(aq) + OH-(aq) -> CH3OH(aq) + Br-(aq) A. addition B. condensation C. elimination D. substitution

Answers

Answer is: D. substitution.

Substitution reaction or single displacement reaction is a chemical reaction in which one functional group in a chemical compound is replaced by another functional group.

Balanced chemical reaction: CH₃Br(aq) + OH⁻(aq) → CH₃OH(aq) + Br⁻(aq).

In this balanced chemical reaction hydroxy group OH⁻ replaced one atom of bromine (Br⁻) in methyl bromide (CH₃Br).

Answer : The correct option is, (D) Substitution reaction.

Explanation :

Addition reaction : It is a type of reaction in which a molecule combined with the another molecule to give a new larger molecule.

The general representation of this reaction is,

$A+B\rightarrow C$

Condensation reaction : It is a type of reaction in which two molecules combine to form a larger molecule and also producing a smaller molecule such as water.

$R_1-OH+H-OOCR_2\rightarrow R_1-O-COR_2+H_2O$

Elimination reaction : It is a type of reaction in which the loss of elements from the starting material to form a double bond in the product.

The general representation of this reaction is,

$HR_1-R_2X+B\rightarrow R_1=R_2+HB^++X^-$

Substitution reaction : It is a type of reaction in which one functional group is replaced by the another functional group.

The general representation of this reaction is,

$AB+C\rightarrow AC+B$

(B and C are the two different functional groups)

In the given reaction, Br (functional group) is replaced by the hydroxide ion (functional group). So, this reaction is a substitution reaction.

Hence, the given reaction is a substitution reaction.

What is the most polar?

A) C-N
B) C-O
C) C-C
D) C-Cl
E) C-F

Answers

I would say that the most polar is E) C-F, because polarity is proportional to the difference in electronegativity. Since carbon is the same in each molecule, you need to focus on non-carbon atom, which is the most polar.

What is the ∆G for the following reaction under standard conditions (T = 298 K) for the formation of NH4NO3(s)? 2NH3(g) + 2O2(g) NH4NO3(s) + H2O(l)Given:
NH4NO3(s): ∆Hf = -365.56 kJ ∆Sf = 151.08 J/K.
NH3(g): ∆Hf = -46.11 kJ ∆Sf = 192.45 J/K.
H2O(l): ∆Hf = -285.830 kJ ∆Sf = 69.91 J/K.
O2(g): ∆Hf = 0.00 kJ ∆Sf = 205 J/K.

Answers

∆G = ∆H - T∆S

NH3: ∆G = -46.11x10^3 - (298)(192.45) = -103460.1 J
O2: ∆G = 0 - (298)(205) = -61090 J
NH4NO3: ∆G = -365.56x10^3 - (298)(151.08) = -410581.84 J
H2O: ∆G = -285.830x10^3 - (298)69.91) = -306663.18 J

∆Grex = ∆Gproducts - ∆Greactants
∆Grex = (-410581.84 + -306663.18) - (-103460.1/2 + -61090/2)
∆Grex =-634969.97 J/mol = -634.97 kJ/mol
