The scientific process has to adapt to what the experiment is.
Answer:
See explanation
Explanation:
A word equation tries to depict a chemical reaction in words. Letters rather than only chemical formulas are used to show the reaction equation.
Now we want to write a word equation that shows the reaction of sodium hydroxide solution and aluminium sulphate solution:
Alumunium sulphate + sodium hydroxide ------>Aluminium hydroxide + sodium sulphate
V₁/T₁ = V₂/T₂ = const
T₁=11+273=284K
V₂=3V₁
V₁/T₁=3V₁/T₂
T₂=3T₁
T₂=3*284=852K
t₂=852-273=579°C
Answer:
mercury, magnesium, water and gasoline.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
The liquid with higher density will sink in bottom while the liquid with lower density will float.
In given samples,
density of water = 1 g/mL
density of mercury = 13.6 g/mL
density of gasoline = 0.70 g/mL
density of magnesium = 1.7 g/mL
So on the basis of given density values mercury will sink in bottom then above it magnesium will present than water and above on these three gasoline will present.
The new volume of the soccer ball is 9 litres when temperature inside the can was 25°C and pressure remained constant.
Explanation:
Data given:
initial volume of the ball, V1 = 3.6 litres
temperature of the field, initial temperature, T1 = 10°C
temperature in the trash can, final temperature, T2 = 25 °C
pressure =constant throughout
volume of the ball when in trash can, final volume V2 =?
From the data given:
Charles' Law will be applied to know the volume of the ball in the can:
putting the values in the equation after rearranging it:
V2 = 
V2 = 
V2 = 9 litres
The volume will be increased to 9 litres when ball will go inside the trash can.
