which is proton(24),neutron (28) and electrons(24)
Answer:
1100 millimeters
Explanation:
1 mole of isopentyl alcohol = 22.4L = 22.4×1000 mL = 22,400L
0.050 moles of isopentyl alcohol = 0.050 × 22,400mL = 1120mL = 1100mL (to two significant figures)
Answer:
32km/hr
Explanation:
The question asks to calculate the average speed for a boat.
Mathematically, the average speed is the total distance divided by the total time
Let’s get the total distance traveled:
That would be 70km + 26km = 96km
Now the total time taken would be 3 as the boat did not move at all for an hour.
The average speed is thus 96/3 = 32km/hr
Answer:
D. none of the above
Explanation:
A. is wrong because pressure and volume have an inverse relationship. When one increases the other decreases, this is not an option.
B. is wrong because temperature and volume have a proportional relationship. One one goes up, the other goes up or vice versa.
C. is wrong because volume cannot increase the then decrease at the same time.
