Answer : The energy removed must be, 29.4 kJ
Explanation :
The process involved in this problem are :
The expression used will be:
where,
= heat released for the reaction = ?
m = mass of benzene = 94.4 g
= specific heat of solid benzene =
= specific heat of liquid benzene =
= enthalpy change for fusion =
Now put all the given values in the above expression, we get:
Negative sign indicates that the heat is removed from the system.
Therefore, the energy removed must be, 29.4 kJ
Answer:
Explanation:
Given information:
A designed dialysis unit consists of a large no of small hollow fibers,
Considering the one fiber,
By using the volume of blood, we have :
where:
L = 30cm = (30× 10) mm = 300 mm
Volume = 80 ml = 80 × 10³ mm
From the above equation, making D the subject, we have:
D² = 339.53
D = 18.43 mm
D = 1.843 cm
However, suppose we consider the laminar flow, the pressure loss in a single fiber can be determined as follows:
where;
Recall:
Finally, the number of needed to be used =
=
= 539.35
Landslides happen when it rains making the ground heaver and more likeable to a landslide.
The answer is <span>D. Nonvascular plants. These plants are usually very short and can't grow to be very tall. A good example is moss.
