Answer:
Dissociation factor = 1.8
Explanation:
Data provided in the question:
Molecular weight of the Procaine hydrochloride = 273
Number of ions contained, n = 2
Fraction Dissociating, α = 80% = 0.8
Now,
the dissociation factor 'i' is given as:
i = 1 + α × ( n - 1 )
on substituting the respective values, we get
i = 1 + 0.8 × ( 2 - 1 )
or
i = 1 + ( 0.8 × 1 )
or
i = 1.8
The scale will read <u>112 grams.</u>
Why?
Since we already know the percent error of the scale (12%) and we also know the mass of the block that is placed on the scale, we can calculate what will be the read of the scale by using the following formula:

We can see that the scale will read 112 grams.
Let's verify that we are right by using the following formula to verify if the obtained value for the scale read will be 12%:

Hence, we can see that the scale will read <u>112 grams.</u>
Have a nice day!
Answer:
a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)
b). The reaction chemical reaction is balanced from the number of moles of reactants and products
Explanation:
Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.
It is a chemical reaction taking place in green plant to produce food which it uses to survive.
Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.
The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2
The products are C6H12O6 O2
and the reactants are CO2 + H20 + (solar (light) energy)
The reaction chemical reaction is balanced from the number of moles of reactants and products
