b. It has a fixed volume and shape.
c. It has high energy and expands to fill the container.
d. It has a fixed volume and varied shape.
For this case, the first thing we are going to do is define a reference system.
We define the vertical axis of the reference system, pointing upwards.
Therefore, doing summation of forces in vertical direction we have:
Then, since we want the net force to be equal to zero, then:
From here, we clear the force that we must apply on the object:
The positive sign means that the force points upwards.
Answer:
to create a net force of zero on the object you must apply:
33 Newton upwards.
Explanation:
because 9 is more than 1.5 and the more water, the more heat
Answer:
a) NaOH volume at the equivalence point is 100 ml.
b) NaOH volume at the equivalence point is 45 ml.
Explanation:
To calculate the concentration of acid, we use the equation given y neutralization reaction:
where,
are the n-factor, molarity and volume of acid.
are the n-factor, molarity and volume of base
a) If a 0.100 M NaOH (aq) solution is used to titrated with 50.0 mL of 0.200 M HBr(aq).
We are given:
Putting values in above equation, we get:
b) If a 0.100 M NaOH (aq) solution is used to titrated with 30.0 mL of 0.150 M (aq).
We are given:
Putting values in above equation, we get:
