Answer:
15.5 km
Explanation:
1.55 x 10^4 m means 1.55 x 10000 = 15,500 m
1 km = 1000 meters
To convert to km we divide by 1000
So 15,500/1000
= 15.5 km
Answer:
D.) molecule
<h3>When the same or different atoms combine together they for a molecule</h3>
Answer:
The volume will be 6, 67 L
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T:
P1xV1/T1 = P2 x V2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((1,5 atm x5 L/300K)x400K)/1,5 atm
V2=6, 67 L
Answer:
D. Solution A has more concentrated acid than solution B and acid in solution A is also a weaker acid than that in solution B.
Explanation:
As it has been said in the question that the volume to reach the equivalence point of the solution A is twice the volume of solution B, this is because the acid in the solution A is more concentrated than B that's why more NaOH was required to reach to the equivalence point.
Since the pH at the equivalence point was greater for solution A that means the acid in solution A was a weak acid that's why the pH raised more as the NaOH was added to the solution.
