Do you think that a synthetic Diamond should be treated like a natural Diamond? Why or why not?

1 answer:

8 0

No, because a natural diamond is a feat of nature and it is amazing how nature made the intricate structure in a diamond. synthetic diamonds are created in laboratory conditions, so it feels less 'amazing' that the diamond was created because each diamond doesn't feel so unique.

However, the molecular structure of both synthetic and natural diamonds are identical, so it is nearly impossible to tell the difference (if you don't know which is which).

An enzyme can catalyze a reaction with either of two substrates, S1 or S2. The Km for S1 was found to be 2.0 mM, and the Km, for

disa [49]

Answer:

101

Explanation:

Provided that

$S_1 = S_2 = same\ V_{max}$

And,

$S_1\ k_M = 2.0mM\\S_2\ k_M = 20mM$

Now we expect the same

{S} (0.1mM)

This determines that $S_1$ generates a higher rate of product formation as compared to the $S_2$

So we can easily calculate the $V_{max}$ for either of $S_1$ or $S_2$ as we know that Tube 1 is $S_2$ and tube 2 is $S_1$

As we know that

$V_0 = V_{max}\ {S} / (K_M + {S})$

As the rates do not include any kind of units so we do not consider the units for $V_{max}$

Now the calculation is

$0.5 = V_{max} (0.1\ mM) / (20\ mM + 0.1\ mM)$

$V_{max} = 0.5 (20.1\ mM) / 0.1\ mM$

= 100.5

How much carbon dioxide (CO2). Is in our atmosphere?

Brut [27]

: Atmospheric Carbon Dioxide. The global average atmospheric carbon dioxide in 2017 was 405.0 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.

For each of the four single-displacement reactions, describe what happened in rachel well. if a chemical reaction occured, write

Ad libitum [116K]

Answer:

Explanation:

Single replacement:

It is the reaction in which one elements replace the other element in compound.

General equation:

AB + C → AC + B

1) zinc and Copper sulfate

Zn + CuSO₄ → ZnSO₄ + Cu

Zinc is more reactive than copper it displaces the copper from copper sulfate and form zinc sulfate.

2) Aluminium and Copper sulfate

2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu

Aluminium is more reactive than copper it displaces the copper from copper sulfate and form aluminium sulfate.

3) Zinc and silver nitrate

Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag

zinc is more reactive than silver it displaces the silver from silver nitrate and form zinc nitrate.

4) copper and silver nitrate

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag

copper is more reactive than silver it displaces the silver from silver nitrate and form copper nitrate.
