Answer:
30.63 °C will be the final temperature of the water.
Explanation:
Heat lost by iron will be equal to heat gained by the water
Mass of iron = 
Specific heat capacity of iron = 
Initial temperature of the iron = 
Final temperature = 
=T
Volume of water = 300 ml
Density of water = 1 g/mL
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = =T
On substituting all values:
we get, T = 30.63°C
30.63 °C will be the final temperature of the water.
Answer:
Avogadro's Law
Explanation:
Avogadro's number (6.23 x 10^23)
Avogadro's law states that the volume and number of moles are proportional if pressure and temp remain constant.
Answer:
The answer is " salt".
Explanation:
Hey there!
When any acids and base react with eachother, they forms water and respective salts.
For example:
HCl + NAOH = NACl + H2O.
