Carbon-13 is an isotope of carbon. The atomic number of carbon is 6. How many neutrons does carbon-13 have?

Answers

Answer 1

Answer: Neutrons = mass no. - atomic no. Therefore depending on your periodic table (mine says 12 for mass number) so you do (mass no. - 6 = 6 or 7 ) depending again if you use 12 or 13

Which of these statements about enzymes is NOT true? - If enough substrate is added, the normal Vmax of a reaction can be attained even in the presence of a competitive inhibitor.
- When [S] << Km, the reaction is second order and V0 depends on [S] and [Et].
- Their kcat is a second order rate constant.
- The lower their Km, the better they recognize their substrate, but the lower their reaction rate.
- When [S] << Km, V0 depends on [S] and [Et].

Answers

Answer:

1. True. 2. True. 3. Not true. 4. True. 5. True

Explanation:

1. Yes, because if the amount of substrate i much greater than of competitive inhibitor then the probability of substrate to bind to ferment is much higher than of inhibitor (if we have noncompetitive inhibitor it damages the structure of active site and the substrate concentration does not have a role in reaction rate).

2. Yeah, because then the michaelis-menten equation will transform into [tex} V0=(kcat*[E]*[S])/Km [/tex] and it is a second order equation.

3. No, because it is measured in sec-1 and that means it is 1 rate constant.

4. True, if the lower Km the better is binding and due to that rate is slower because it's harder for substrate to unbind.

5. The same as question two.

Which statement best describes the collisions of gas particles according to the kinetic-molecular theory? a. When particles pass close enough to one another, their attractions pull them together, and then they bounce apart with no gain or loss of energy.
b. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
c. When particles pass close enough to one another, their attractions pull them together, and then they bounce apart with a loss of energy.
d.As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with a loss of energy.

Answers

Answer:

b. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Explanation:

Kinetic - molecular theory -

According to this theory , gas is considered to be as a large number of very small particles , which moves randomly , and due to this randomness collisions occurs , as the particles collide with each other and the wall of the container .

During these collisions , there is no loss or gain of energy , there is only transfer of energy .

Answer:

As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Describe several uses for plastic and explain why plastic is a good choice for these properties

Answers

Plastics are used in almost all spheres of life for diverse purposes because of their beneficial properties. The uses of plastics include the following:

1. Plastics are used in the manufacturing of various items that we use in our homes such as television, phones, radio, vacuum cleaners, chairs, bowls plates, tables, etc.

2. Plastics are used in the food industry for packaging of foods.

3. Plastics are used in the transport industry for various purposes in the manufacture of cars, trains, aeroplanes, hydroplanes, ships, satellites, etc.

4. Plastics are also used in the medical and pharmaceutical industries for various purposes.

Manufacturers are able to use plastics for various purpose because of their properties, which include: resistance to corrosion, resistance to chemicals, low thermal conductivity, color variability, high strength to weight ratio, resistance to shock, durability, low toxicity, ready availability, cheap, etc.

Plastic is used in several in the worlds toys, bags and products. Its a good choice for these properties because plastic is a low cost and is very durable and flexible allowing it to ease the process of making these products.
