Mass of each atom of carbon = 12
No of carbon atom = 6
Total mass of carbon atom = 12 X 6 = 72
Mass of each atom of hydrogen = 1
No of hydrogen atom = 12
Total mass of hydrogen atom = 1 X 12 = 12
Mass of each atom of oxygen = 16
No of oxygen atom = 6
Total mass of oxygen atom = 16 X 6 = 180
Total: 180 g / mole glucose
No of atoms = 200 g glucose / 180 g/mole glucose * 6.022 X 10^23 molecules glucose/mole glucose * 24 atoms/molecule glucose
= 16.044 X 10^24 atoms are present in 200 grams of glucose
Hope it helps!!!
Lidocaine is used as a local anesthetic and cardiac depressant. when lidocaine reacts with HCL, the tertiary amine reacts with HCL to form an amine salt of lidocaine hydrochloride. This reaction reaction can be represented as
Answer:
=0.1293 J
Explanation:
The heat increase is the change in energy for the water ΔH.
ΔH=MC∅ where M is mass, C is the specific heat capacity for water and ∅ is the change in temperature.
M=0.7892g
C(for water) =4.2 J/g°C
∅=0.039 °C
ΔH=0.7892g×4.2 J/g°C×0.039°C
=0.1293 J
The amount of heat energy added to cause the 0.039°C temperature increase is 0.1293 Joules.
Answer:
<h2>The answer is option A</h2>
Explanation:
To find out if the object sink or float in water we must first find the density of the object
From the question
mass of object = 2 g
volume = 4 mL
The density is
We have the answer as
0.5 g/mL
The object will float on water since it's density is less than that of water which is
1.0 g/mL
Hope this helps you
For the empirical formula I got H28C1
I’m not sure how to do the others sorry
