Answer : The correct option is "record 10.00 ml in the notebook after using it."
Explanation :
If an instrument has "10 mL TD" written on it, that means the instrument is meant To Deliver (TD) 10 mL of volume.
Therefore the option that has 5.00 mL is not correct.
"+/- 0.01 mL" indicates the precision of the instrument. We know that no measurement is 100% accurate and there is always some uncertainty associated with any measurement.
Here, 0.01 indicates the uncertainty in the measurement.
When we have 0.01 mL , that means the instrument can record precisely to the hundredths place.
The more the significant figures, the greater is the accuracy of the measurement.
Therefore when we use an instrument that has "+/- 0.01 mL" written on it, we should record the reading as 10.00 mL
Answer: a piece of pure matter which we can see from our naked eye is termed as a substance
Explanation:
every substance has physical and chemical properties like;
diamond ,water ,pure sugar ,table salt e.t.c
an element is a substance made up of same type of atoms having same atomic number[protons],and cannot be easily decomposed in to a single substance by ordinary chemical reaction example,.....
gold,copper,zinc and some are in liquid form like mercury,bromine and some are in gases for example, hydrogen ,oxygen, nitrogen
Answer:
moles of glucose
<u>2.3166 moles of glucose</u>
<u></u>
Explanation:
The balance reaction for the formation of glucose is :
here , CO2 = carbon dioxide
H2O = water
C6H12O6 = glucose
O2 = Oxygen
According to this equation :
6 mole of CO2 = 6 mole of H2O = 1 mole of C6H12O6 = 6 mole of O2
We are asked to calculate the mole of Glucose from carbon dioxide.
So,
6 mole of CO2 produce = 1 mole of C6H12O6
1 mole of CO2 will produce =
moles of glucose
13.9 moles of CO2 will produce :
=2.3166 moles of glucose
Note : first , Always calculate for one mole (By dividing)
. After this , multiply the answer with the moles given.
Always write the substance whose amount is asked(glucose) to the right hand side
