Answer:
24g of NaOH are required
Explanation:
Molarity, M, is an unit of concentration widely used in chemistry defined as the ratio between moles of solute (In this case, NaOH), and volume of solution in liters.
We can find the moles of NaOH and its mass with the volume and desired concentration as follows:
<em>Moles NaOH:</em>
400.0mL = 0.400L * (1.50mol / L) = 0.600 moles NaOH
<em>Mass NaOH -Molar mass: 40.0g/mol-:</em>
0.600 moles * (40.0g / mol) =
<h3>24g of NaOH are required</h3>
Answer:
The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.
Explanation:
Hope that made sense!
Answer: The system will try and offset the change.
Explanation: Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in a direction to minimize the effect.
Thus if temperature is increased, the reaction will shift in a direction where temperature is decreasing and vice versa. Similarly if pressure is increased, the reaction will shift in a direction where pressure is decreasing and vice versa.
The question is incomplete, complete question is:
A fluid occupying 
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V =
Density of the fluid = D
Specific volume is the reciprocal of the density :
Specific volume of the fluid = 
2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft
Specific volume of the fluid :
3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft
Specific volume of the fluid :
