Answer:
equals
Explanation:
<h3>it means that forward reaction equals to reverse reaction</h3>
True that in the preindustrial era, settlements were more likely to be near sources of surface water than in the industrial era. The main reason being that during the preindustrial era people were dependent mostly on irrigation. For irrigation people were dependent on surface water. This was the main and basic reason.
Soda ash which is also referred to as sodium carbonate with a chemical formula (NaCO3) has the following chemical formula
The melting point of 851 degrees
The molecular weight of 105.98
Its density at 25 degrees is =2.53 g/cm^3
Its specific heat capacity at 25 degrees = 0.249 cal/gm/ 0c
Answer:
The correct answer to this is
e. all of the above
Explanation:
An hypothesis is a proposal to solve or answer a new or strange phenomenon that is not suitably explained by current scientific knowledge. The outcome of an hypothesis is not predetermined. An hypothesis can be termed a scientific hypothesis only when the statements of the hypothesis can be tested also known as the testability of the hypothesis. Hypothesis are normally focused on observations that are unexplained by current scientific theories
Answer : The boiling point of water increases, 
Solution : Given,
Moles of solute (sugar) = 4 moles
Mass of solvent (water) = 1 Kg
i = 1 for sugar
Formula used :
Where,
= elevation in boiling point
= elevation constant
m = molality
= moles of solute (sugar)
= mass of solvent (water)
i = van't Hoff factor
Now put all the given values in this formula, we get the elevation in boiling point of water.
Therefore, the elevation in boiling point of water is
