Answer:
188.5g of dextrose are needed
Explanation:
In Weight per volume percentage - %(w/v) -, the concentration is defined as the mass of solute in grams -In this case, dextrose-, in 100mL of solution.
As you want to prepare 725mL of a 26.0% (w/v) solution. you need:
725mL * (26g / 100mL) = 188.5g of solute =
<h3>188.5g of dextrose are needed</h3>
Explanation:
Modeling crustal deformation is a very important process that helps to study plate interaction that clearly can be used to predict the likelihood of an earthquake.
Earthquake is a sudden displacement or movement with the earth that transmits elastic energy.
- Earthquakes can have shallow or deep focus depending on their location and the terrain.
- Movement on the earth are mostly noticeable along plate margins.
- This results in a world-wide movement of the broken slabs of the earth moving on the weak asthenosphere.
- It is impossible to go deep within the lithosphere to identify unstable earth.
- The uneven distribution of stress is very important in this process.
- As plate moves, the lithosphere deforms creating stresses in some area and relieving other places of stress.
- Continuous collection of stress data using strain mapping gives important parameters that can be modeled.
- Areas with high amount of stress and more movement have the highest tendency of producing earthquakes.
- A computer model is used to carry out this prediction.
- Some other factors contributes to the rapid movement but stress are by far the most important of all.
- By this, we can easily and readily hypothesize the causes of an earthquake and possible measures to mitigate it.

During a phase change the temperature does not change since all of the heat is being absorbed in order to break the intermolecular forces. Due to that, the formula will not need to have T in it and is actually q=nΔH(v).
n=the number of moles (in this case 2.778mol of water since you divide 50g by 18g/mol).
ΔH(v)=the molar heat of vaporization (in this case 40.7kJ/mol).
q=the heat that must be absorbed
q=2.778mol×40.7kJ/mol
q=113.1kJ
Therefore the water needs to absorb 1.13×10²kJ.
I hope this helps. Let me know if anything is unclear.
Answer:
it is good for thermoelectric power plant cooling
it means that there is a lot of salt in the water
Someone would remove salt from water to be able to drink it
lastly, salt can be removed from water with reverse osmosis systems

hello your question is incomplete the options are missing
Determine the resultant velocity for the plane when it is travelling
i) To the east
ii) To the west
answer :i) 270 i
ii) -150 i
Explanation:
velocity of Airplane = 210 m/s
wind velocity = 60 m/s to the east
The resultant velocity for the plane when it is travelling
let the velocity of the wind = V2
velocity of the plane = v1
i) The resultant velocity for the plane when travelling to the east
Vr = V2 i + V1 i
Vr= 60i + 210i = 270i
ii) resultant velocity when the plane is travelling to the west
Vr = - V1 i + V2i
= -210i + 60 i = -150 i
