Which diagram illustrates that matter is always conserved in a chemical reaction?

Answers

Answer:

Only the third option has the same number of each size and color circles on either side of the arrow.

Explanation:

I believe it represents the dissolution of two molecules of hydrogen peroxide into two water molecules and an oxygen gas molecule.

The first one balances oxygen but changes sulfur with either carbon or nitrogen

The second one needs 5 oxygen gas pairs instead of a single one on the left to balance the right side. Represents oxidation of a propane molecule if given enough oxygen.

The fourth one has an extra nitrogen on the left side. The hydrogen is balanced. Making amonia.

. The artificial sweetener NutraSweet is a chemical called aspartame (C14H18N2O5). What is (a) its molecular mass (in atomic mass units)? (3) (b) the mass (in kg) of an aspartame molecule?​

Answers

The molecular mass, in atomic mass unit, of aspartame would be 294 amu while the mass, in kg, of an aspartame molecule would be 0.294 kg

Aspartame has the chemical formula C14H18N2O5

C = 12, H = 1, N = 14, O = 16

(a) Molecular weight = (12x14) + (1x18) + (14x2) + (16x5)

                                  = 168 + 18 + 28 + 80

                                    = 294 amu

(b) Mass of 1 molecule of aspartame = mole x molar mass

                                    = 1 x 294

                                        = 294 g

Converting 294 g to kg = 294/1000

                                         = 0.294 kg

One of your classmates, in a fit of unrestrained ego, jumps onto a lab table:
a) Draw a qualitative force diagram for the table. Use marks on the vectors to show the balance of forces.
b) Your classmate’s mass is 65 kg and the table weighs 0 N. Calculate the normal force on the table by the floor. Show your work!
c)Find the mass of the table

Answers

The equilibrium condition allows finding the results for the forces of the system are

      a) The free body diagram is in the attachment

      b) The normal force is N = 737 N

      c) The mass of the table is  10.2 kg

Newton's second law indicates that the net force is proportional to the product of the mass and the acceleration of the bodies, in the special case that the acceleration is zero, it is called the equilibrium condition

          ∑ F = 0

Where the bold letters indicate vectors, F is the external forces

a) A free body diagram is a scheme of the forces without the details of the bodies, in the attachmentt we see a free body diagram of the system.

b) The reaction force of the ground is applied in each of the legs of the table, in general this force has the same magnitude in each leg, therefore in Newton's second law we can place it as a single force

             N = N₁ + N₂ + N₃ + N₄₄

Let's apply the equilibrium condition

                N -  [tex]W_m -w_{table}[/tex] = 0

                N =  [tex]W_m +w_{table}[/tex]

                N = [tex]M_m g + w_{table}[/tex]  

They indicate the pose of the boy is 65 kg, for the weight of the table of a laboratory table is approximately 100 N

                N = 65 9.8 + 100

                N = 737 N

c) To calculate the mass of the table we use the relation

                W = [tex]m_{table}[/tex] g

                [tex]m_{table} = \frac{w_{table}}{g}[/tex]

                [tex]m_{tabble}= \frac{100}{9.8}[/tex]  

               [tex]m_{table}[/tex]e = 10.2 kg

In conclusion using the equilibrium condition we can find the results for the forces are

      a) The free body diagram is in the attachment

      b) The normal force is N = 737 N

      c) The mass of the table is  10.2 kg

At the temperature [tex]10^{7}K[/tex] the hydrogen atoms fuse to form helium thus a large amount of heat is produced and stars are formed.

What causes a star to form?

Due to gravitational pull the particles and the molecules of gases become condense and by which it becomes hot. The process goes unless the temperature of the core becomes 10,000,000K.

At this temperature, the fusion takes place and energy is released.

[m/s] = A [s]³ - B [s]

A ball is dropped from a tower that is 206 m high, How long does it take to reach the ground?

Answers

It will take 6.42 s for the ball that is dropped from a height of 206 m to reach the ground.

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

Height (H) = 206 m

Time (t) =?

NOTE: Acceleration due to gravity (g) = 10 m/s²

The time taken for the ball to get to the ground can be obtained as follow:

H = ½gt²

206 = ½ × 10 × t²

206 = 5 × t²

Divide both side by 5

[tex]t^{2} = \frac{206}{5}\\\\ t^{2} = 41.2[/tex]

Take the square root of both side

[tex]t = \sqrt{41.2}[/tex]

t = 6.42 s

Therefore, it will take 6.42 s for the ball to get to the ground.

Does a paddle boat’s wheel rotate clockwise or counterclockwise? PLS HELP

Answers

Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.

Knowing of and understanding propeller walk is important when maneuvering in small spaces. It can be used to one's advantage while mooring off, or it can complicate a maneuver if the effect works against the pilot.

Calculate the kinetic energy of a 70 kg person moving at a speed of 5m/s

Answers

Answer:

875 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]k = \frac{1}{2} m {v}^{2} \\ [/tex]

m is the mass

v is the velocity

From the question we have

[tex]k = \frac{1}{2} \times 70 \times {5}^{2} \\ = 35 \times 25 \\ = 875[/tex]

We have the final answer as

875 J

Hope this helps you

Answer:

[tex]\boxed {\boxed {\sf 875 \ Joules}}[/tex]

Explanation:

Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula:

[tex]KE= \frac{1}{2}mv^2[/tex]

The mass of the person is 70 kilograms and they are moving at a speed of 5 meters per second.

m= 70 kg v= 5 m/s

Substitute these values into the formula.

[tex]KE= \frac{1}{2} (70 \ kg )(5 \ m/s)^2[/tex]

Solve the exponent.

(5 m/s)² = 5 m/s * 5 m/s = 25 m²/s²

[tex]KE= \frac{1}{2}(70 \ kg)(25 \ m^2/s^2)[/tex]

Multiply the numbers in parentheses.

[tex]KE= \frac{1}{2} (1750 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]KE= 875 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 875 kg*m²/s² is equal to 875 Joules.

[tex]KE= 875 \ J[/tex]

The person has 875 Joules of kinetic energy.
