balance this
C3H3N + O2 ⇒ C + H2O + N2

Answers

Answer 1

Answer:

4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

Explanation:

The given reaction equation is expressed as:

        C₃H₃N   +    O₂    →   C  +   H₂O    +     N₂

The problem here entails balancing of the chemical reaction.

 So;

assign letters a,b,c,d and e as coefficients that will balance the expression:

 

            aC₃H₃N   +    bO₂    →   cC  +   dH₂O    +     eN₂

Conserving C :  3a  = c

                   H :   3a  = 2d

                   N :    a = 2e

                   O:    2b  = d

let a  = 1, c  = 3, e  = [tex]\frac{1}{2}[/tex]  , d  = [tex]\frac{3}{2}[/tex]  , b  =  [tex]\frac{3}{4}[/tex]

    Multiply through by 4;

          a  = 4, b  = 3, c  = 12 , d  = 6 and e  = 2

                4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

As the radius of a star increases, how do you think its mass might change?

Answers

Answer:

by wind

Explanation:

As the radius of the star increases, the mass will also increase.

This is all about the relationship between the radius and mass of stellar main sequence stars.

Now, usually they are expressed in solar units and as such as seen in the graph image attached, the relationship between the radius(R) and mass(M) of a main-sequence star is seen by the curve attached. It is clear that the higher the radius becomes, the larger the mass of the star also becomes.

To clarify this also, we have a mass - lumosity relationship formula where given as;

L = [tex]M^{3.5}[/tex]

Where;

M is mass

L is lumosity

We know from basics of stellar main sequence stars, that a larger radius gives a much brighter lumosity.

From the mass-lumosity formula, we see that Increase in lumosity is directly proportional to an increase in mass. Therefore in the same vein, we can say that increase in radius is directly proportional to an increase in mass.

3. How many grams of oxygen are needed for the
complete combustion of 11 grams of propane, C3H8?
C3H8 + 5 O2 + 3 CO2 + 4 H2O

Answers

Answer:

Mass = 40 g

Explanation:

Given data:

Mass of oxygen needed = ?

Mass of propane = 11 g

Solution:

Chemical equation:

C₃H₈ +5O₂   →     3CO₂ + 4H₂O

Number of moles of propane:

Number of moles = mass/molar mass

Number of moles = 11 g/ 44.1 g/mol

Number of moles = 0.25 mol

now we will compare the moles of propane and oxygen.

              C₃H₈        :          O₂

                  1           :            5

                0.25      :            5/1×0.25 = 1.25 mol

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 1.25 mol × 32 g/mol

Mass = 40 g

In the reaction Cu(s) + 2 AgNO3(aq) -> 2 Ag(s) + Cu(NO3)2(aq) how much Ag can be produced from 49.1 g of copper

Answers

Answer:167.9 g Ag

Explanation: 1 mol Cu + 2 mol AgNO3 = 2 mol Ag + 1 mol Cu(NO3)2

63.55 g Cu —> 2*107.688 g Ag

So 49.1 g Cu —> (49.1/63.55)*2*107.688 = 167.9 g Ag

The complete combustion of acetic acid, HC2H3O2(I) to form water, H2O(I), and CO2(g), at constant pressure releases 871.7 kJ of heat per mol of acetic acid.
Write a balanced thermochemical equation if 5.0g of acetic acid will be used in the reaction.
HC2H3O2(I) + O2 --- H2O(I) + CO2(g) H= -871.7 kJ

Answers

Answer:

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Explanation:

We know that 5.0 g of acetic acid will contain, 5.0g/60 g/mol = 0.083 moles of acetic acid

Now from the reaction equation;

1 mole of acetic acid evolved -871.7 KJ of heat

0.083 moles of acetic acid will evolve 0.083 * -871.7 = -72.35 KJ

For 5.0 g of acetic acid, we can write;

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Which best describes the effect of a ecosystem when populations of white-tailed deer are overhunted by people in an area?

A. It disrupts the balance between predators and prey
B. It decreases the amount of producers
C. It directly increases the population of decomposers
D. It decreases competition for food among carnivores

Answers

Answer:

A. It disrupts the balance between predators and prey

Explanation:

The effect on the ecosystem when populations of white  - tailed deer are overhunted is that it disrupts the balance between predators and prey within the ecosystem.

The whited - tailed deer is the usually the prey. The carnivores are the cats and other flesh eating animals. When the deer is over-hunted, there are more predators compared to prey. This leads to a serious imbalance and a high level of competition for the scarce prey.

The molecular weight of KMnO4 is 158 g/mol. If you wanted to make 500 mL of a 0.1M stock solution of KMnO4, how much solid KMnO4 would you need to add before filling mL flask of water?

Answers

Solid KMnO₄ needed = 7.9 g

Further explanation

Given

MW KMnO₄ = 158 g/mol

500 mL(0.5 L) of a 0.1M stock solution of KMnO₄

Required

solid KMnO₄

Solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Input the value :

n = M x V

n = 0.1 M x 0.5 L

n = 0.05 mol

Mass KMnO₄ :

= mol x MW

= 0.05 x 158 g/mol

= 7.9 g

The solid KMnO₄ a person need to add before filling water flask will be:

"7.9 g".

Molecular weight

According to the question,

Molecular weight of KMnO₄ = 158 g/mol

Volume of solution = 500 mL or,

                                = 0.5 L

Molarity = 0.1 M

We know the relation,

Molarity, M = [tex]\frac{n}{V}[/tex]

or,

→ n = M × V

By substituting the values,

     = 0.1 × 0.5

     = 0.05 mol

hence,

The mass of KMnO₄ will be:

= mol × Molecular weight

= 0.05 × 158

= 7.9 g

Thus the response above is appropriate.

Radio waves are used to transmit information on various channels. What is the wavelength of a radio wave having the frequency of 5.40 × 1010 Hz?

1. Analyze the Problem

ν = and c = Unknown: λ =

You know that because radio waves are part of the electromagnetic spectrum, their speed, frequency, and wavelength are related by the formula c = λν.

Answers

Answer:

5.56×10¯³ m

Explanation:

From the question given above, the following data were obtained:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

The velocity of electromagnetic wave, frequency and wavelength are related according to the equation:

Velocity (c) = wavelength (λ) × frequency (v)

c = λv

With the above formula, the wavelength of the radio wave can be obtained as follow:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

Velocity (c) = 3×10⁸ m/s

c = λv

3×10⁸ = λ × 5.4×10¹⁰

Divide both side by 5.4×10¹⁰

λ = 3×10⁸ / 5.4×10¹⁰

λ = 5.56×10¯³ m

Thus, wavelength of the radio wave is 5.56×10¯³ m

Substance X has a specific heat capacity that is twice as large as Substance Y. If both samples ended up at the same change in temperature from the same amount of energy added, what is the relationship between the masses of the two samples? Explain.

Answers

Answer:

Substance X has a smaller mass

Explanation:

The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.

 The specific heat capacity is given as:

         C  = [tex]\frac{H}{m x change in temperature}[/tex]

We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.

If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass
