They're based on hydrogen.

Answer:

Hydrogen

Explanation:

Standard reduction potential is a measure of the tendency of an atom to attract electrons and get reduced. Higher the reduction potential i.e. more positive the value greater will be the tendency to get reduced. These values are measured at 298 K and 1 atm and expressed in terms of volts.

The standard reduction potential of Hydrogen is taken as zero and the values of all other elements are deduced based on hydrogen. These are tabulated in the thermochemical reduction potential table. The reduction equation for hydrogen is:

H2(g) + 2e-  → 2H+           where E⁰ = 0.00 Volts

Do all mutations affect the STRUCTURE of proteins ? Do all mutations affect the FUNCTIONS of proteins??
finlep [7]

Answer:

1. No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development.

2. No. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

What is the hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4.
Maksim231197 [3]

The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7.

pH= -log[H+] - (i)

10^-3=H2So4

H+= 2×10-3

here ,

h2so4 ——— 2[H+] + so4^2-

thus [H+]= 2*10^(-3) because hydrogen ion has two moles

pH= -log[H+]

pH= -log(2×10^-3)

pH= 3-log2

pH= 3-log2pH= 2.7

The pH is 2.7

<h3>What is pH?</h3>

PH is the degree of alkalinity and acidicity in a solution.

Therefore, The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7

How many milliliters of ammonium sulfate solution having a concentration of 0.218 M are needed to react completely with 62.6 ml
BartSMP [9]

Answer:

330 mL of (NH₄)₂SO₄ are needed

Explanation:

First of all, we determine the reaction:

(NH₄)₂SO₄  +  2NaOH →  2NH₃  +  2H₂O  +  Na₂SO₄

We determine the moles of base:

(First, we convert the volume from mL to L) → 62.6 mL . 1L/1000 mL = 0.0626L

Molarity . volume (L) = 2.31 mol/L . 0.0626 L = 0.144 moles

Ratio is 2:1. Therefore we make a rule of three:

2 moles of hydroxide react with 1 mol of sulfate

Then, 0.144 moles of NaOH must react with (0.144 .1) /2 = 0.072 moles

If we want to determine the volume → Moles / Molarity

0.072 mol / 0.218 mol/L = 0.330 L

We convert from L to mL → 0.330L . 1000 mL/1L = 330 mL
