Answer:
because the acid properties of aspirin may be problematic.
Answer:
See explanation
Explanation:
Temperature is defined as a measure of the average kinetic energy of the molecules of a body.
When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.
When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid
250 --> 125 --> 62.5 --> 31.25
each arrow equals one half life, so 3 half lives
14 days/ 3 half lives =
4.67 days = half life
Answer: 2
Explanation: bencause they are changing
Answer:
0.16mole
Explanation:
To solve this problem, we are going to assume that the number of moles of carbon to be determined is that at STP, standard temperature and pressure.
The number of moles of a substance at STP is given as;
Number of moles = 
Given volume = 3.5L
Now, insert the parameters;
Number of moles = 
= 0.16mole
