<u>Answer:</u> The density of the cube of metal is 8.91g/cm^3

<u>Explanation:</u>

To calculate the volume of cube, we use the formula:

V=a^3

where,

a = edge length of cube

Edge length of cube = 1.2 cm

Volume of cube = (1.2)^3=1.728cm^3

To calculate density of a substance, we use the equation:

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

We are given:

Mass of cube = 15.4 g

Volume of cube = 1.728cm^3

Putting values in above equation, we get:

\text{Density}=\frac{15.4g}{1.728cm^3}=8.91g/cm^3

Hence, the density of the cube of metal is 8.91g/cm^3

The turnover number is defined as the maximum number of substrate molecules that can be converted into product molecules per uni
Nataliya [291]

Answer:

Explanation:

turn over number = R max / [E]t   = K2

From given , R max = 249 * 10 ^ -6 mol. L^-1

T [E]t = 2.23 n mol. L^-1

           =   2.23 * 10^-9 mol. L^-1

Putting values in above equation,

=          111.65 * 10^3           S^-1

Turn over number is maximum no of substrate molecule that can be converted into product molecules for unit time by enzyme molecule.

Which is a reactive nonmetal???
ololo11 [35]
Sodium is very reactive but it’s a metal, and the problem asks specifically for a non-metal.
Silicone is technically reactive, but not super reactive.
Argon is a nonmetal, however it is an inert gas. It doesn’t react with anything.

We’re left with Chlorine, which is a non-metal in group 7, a highly reactive group, on the periodic table.

Part B
sashaice [31]

The anticodons corresponding to the codons on the mRNA (from part A) is 5' CGA - AAA - GUU 3'.

<h3>What are anticodons?</h3>

Anticodons are nucleotide sequences on tRNA molecules that are complementary to the codons found on mRNA molecules.

The anticodons on tRNA molecules determine the amino acid that is carried by the tRNA.

Just like codons, anticodons occur in triplets of nucleotide sequences.

Considering the codons on the mRNA molecule:

3’ GCT | TTT | CAA | AAA ’5

The complementary anticodon will be:

5' CGA - AAA - GUU 3'
