Answer:
Enzyme.
Explanation:
Enzymes act as a catalyst in all reaction but remain unchanged by the process.
B) oxygen, because oxygen is the only element that is in both chemical formulas.
Answer:
0.8988
Explanation:
To calculate the fractional saturation of hemoglobin , the formula used is
YO_2=
now putting the values
YO_2=
=
=0.8988
Therefore, fractional saturation of hemoglobin= 0.8988
where
YO_2= fractional saturation of hemoglobin
pO_2= partial pressure of oxygen
p50= is the pO_2 at which hemoglobin is 50% saturated
The correct answer here would be A because its chemical name is sodium carbonate which is more basic than sodium bicarbonate, if you added soda ash to the solution then that would increase the ph of the solution

Looking at the formula, 1 mole of KIO3 and 5 moles of KI will react and produce moles of iodine molecules or 6 moles of iodine atoms. So first, determine the number of moles of KIO3 and KI provided
moles KIO3 = 0.0121 * 0.097 = 0.0011737 mol
moles KI = 0.0308 * 0.017 = 0.0005236 mol
The limiting reactant is KI at 0.0005236 mol so divide by 5 and multiply by 6 to get the number of moles of iodine atoms.
0.0005236 / 5 * 6 = 0.00062832 mol
Lookup the atomic weight of iodine which is 126.90447
And multiply that by the number of moles of iodine produced
126.90447 g/mol * 0.00062832 mol = 0.079736617 g
Rounding to 4 decimal places gives 0.0797 g</span>
