Answer:

true

Explanation:

Ground state electron configurations are the foundation for understanding molecular bonding, properties, and structures. From the electrons in an atom, to the differing orbitals and hybridization, the ground state electron configuration sheds light on many different atomic properties.

Which statement below correctly describes how amino acids join?

Shtirlitz [24]

Answer:

Amino acids join by linking the acid group of one amino acid to the amino group of another.

Explanation:

Amino acids are organic molecules that form the basic molecules for making proteins and there are. An amino acid comprises of an acidic carboxyl (-COOH) functional group and an amino group (-NH2) as well as a side an organic side chain (R group).

In the formation of proteins, several amino acids join together by the formation of peptide bonds between each amino acids to form a long polypeptide. These peptide bods are formed by the linking of the acidic carboxyl group of one amino acid to the amino group of another amino acid, during this process water is removed.

This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea

Arisa [49]

Explanation:

The given reaction is as follows.

$E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P$

Here, [E] = triose phosphate isomerase = 0.1 $nm = 0.1 \times 10^{-9}m$

[S] = Dihydroxy acetone phosphate = 5 $\mu m = 5 \times 10^{-6}m$

[P] = Glyceraldehyde-3-phosphate = 2 $\mu m = 2 \times 10^{-6}m$

Therefore, velocity of the reaction will be as follows.

v = $\frac{d[P]}{dt}$ = $\frac{K_{2}[E][S]}{K_{M} + [S]}$

where, $K_{M}$ = Michaelic menten constant = $\frac{K_{1} + K_{2}}{K_{1}}$

v = $\frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}$

= $30 \times 10^{-9} m$

or, = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

Find the initial temperature of 45.0g of water if its final Temperature after submerging a metal with the mass of 8.5g is 22.0°C

Korolek [52]

The initial temperature of the water that resulted in the final temperature of the water-metal mixture is 20.7 ⁰C.

"Your question is not complete, it seems to be missing the following information;"

the specific heat capacity of the metal is 0.45 J/g⁰C.

The given parameters;

mass of water, $m_w$ = 45 g
final temperature of the water, $t_w$ = 22 ⁰C
mass of the metal, m = 8.5 g
initial temperature of the metal, t = 82 ⁰C.
specific heat capacity of the metal, c = 0.45 J/g⁰C.

The initial temperature of the water will be calculated by applying the principle of conservation of energy;

heat gained by water = heat lost by metal

$Q_{water} = Q_{metal}$

$m_wc_w \Delta t_w = mc\Delta t$

where;

$c_w$ is the specific heat capacity of the water = 4.184 J/g⁰C.

Substitute the given values;

45 x 4.184 x (22 - t) = 8.5 x 0.45 x (85 - 22)

4142.16 - 188.28t = 240.98

188.28t = 4142.16 - 240.98

188.28t = 3901.18

$t = \frac{3901.18}{188.28} \\\\t = 20.7 \ ^0 C$

Thus, the initial temperature of the water that resulted in the final temperature of the water-metal mixture is 20.7 ⁰C.

Meaning of rust and rusting

Yuki888 [10]

Answer:a reddish- or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation, especially in the presence of moisture.

Explanation: so basically rusting happens when a metal comes in contact with moisture and air, at a brown, dirty metal coat forms on it.
