Explanation:
Number of moles of NaOH = 0.3868 L × 1.707 M = 0.660 moles
Reaction of Al^3+ and OH^-
Al^3+(aq) + 3OH^-(aq) -----> Al(OH)3(s)
If 1 mole of Al3+ reacts with 3 moles of OH^-
x moles of Al^3+ reacts with 0.660 moles of OH^-
x = 1 × 0.660/3
x= 0.22 moles
Mass of Al^3+ = 0.22 moles × 27 g/mol = 5.94 g of Al^3+
Co^2+(aq) + 2OH^-(aq) ----> Co(OH)2(s)
1 mole of Co^+ reacts with 2 moles of OH^-
x moles of Co^2+ reacts with 0.660 moles of OH^-
x = 1 × 0.660/2 = 0.33 moles
Mass of Co^2+ = 0.33 moles × 59 g/mol = 19.47 g
Answer: A. aldolase
Explanation:
Phosphofructokinase, is an enzyme which is vital in the regulation of fermentation. It is involved in the glycolysis process.
When it experiences a mutation that was being interfered with the substrate binding, we should note that the enzyme that is going to be most immediately impacted in terms of accessing substrate is aldolase.
There are 5.66 moles of hydrogen in the sample of talc(hydrated magnesium silicate).
Given,
Talc formula is
moles of magnesium = 8.5 moles
The stoichiometry of magnesium and hydrogen is 3 : 2,
So 3 moles of magnesium is equivalent to 2 moles of hydrogen.
Then 8.5 moles of magnesium is equivalent to =5.6666 moles
<h3>Talc </h3>
Talc(hydrated magnesium silicate), often known as talcum, is a type of clay mineral made up of hydrated magnesium silicate, having the formula Mg3Si4O10(OH)2. Baby powder is made of powdered talc, frequently mixed with corn starch. This mineral serves as a lubricant and thickening agent. It serves as a component in paint, pottery, and roofing materials. It serves as a key component in many cosmetics. It can be found as foliated to fibrous aggregates and in a remarkably uncommon crystal form. It is foliated with a two-dimensional platy form, has a flawless basal cleavage, and an irregular flat fracture.
Talc(hydrated magnesium silicate), the softest mineral, is assigned a value of 1 on the Mohs scale of mineral hardness, which is based on scratch hardness comparisons.

The answer is SiO2
Since silicon has four valence electrons and each oxygen has 2, for every 1 silicon there must be 2 oxygen to fill in both element's outer shells satisfactorily. An alternative way to figure out the chemical formula is to simply swap the charges.
Silicon is a -4 and oxygen is a -2.
Oxygen's charge is brought down into subscript and set as the number of silicons in the chemical formula, making silicon Si2. Silicon's charge is brought down to make the number of oxygens in the chemical formula O4. The formula we have currently is Si2O4. Simplify it to get the empirical formula (divide by 2) and you get SiO2.
