Yes.
Explanation:
Yes, I agree with Bryce and his lab partner because titration is completed when the solution changes its colour. Add chemical from the burette until the solution change its colour so then calculate the amount of chemical is used from the burette and the time at which the titration is completed. Always be careful for calculating the titration in order to get accurate data of the solution.
The answer is B. A guitar generally produces sound waves that propagate when the strings are strummed. The strings are displaced through the vibrations caused by contact of the hand and the guitar. You will also notice the vibrations by looking closely to the string. Wave particles continuously collide with each other to make a sustaining or prolonging sound.

Explanation: Metals' atoms are closely bonded in a crystal lattice. In metallic bonds, the electron cloud boundaries of atoms touch each other. Many nonmetals occur as diatomic molecules. The electron clouds of these two bonded nonmetal atoms overlap .
The moles of nitrogen in 0.30 mole of caffeine is calculated as follows
write the chemical formula = C8H10N4O2
for this case from the chemical formula we have 4 atoms of nitrogen in caffeine
therefore moles of nitrogen in caffeine = 4 x0.30 =1.2 moles
Answer:
53,600 centimeters
Explain; kilo=1000
hecta=100
deca=10
unite=0(meter,leter,
deci=0.1
centi=0.01
milli=0.001
0.536 kilo is opposite of 536,000 milli
