Answer:
well according to salesman they take out all and out all bacteria that is in the water that the water filters installed in the systems already don't take out so in other wordsthere and the water filter takes that out
There are many properties to substances.
I'll list some examples below:
- Mass
- Volume
- Density
- Conductivity
- Malleability
- Boiling point
- Melting point
- Heat capacity
Hope this helps! :3
Answer:
option c
Explanation:
E = hf
E= energy
h = Planck constant
f = frequency
E = 6.6 X 10^-34 X 4 X 10^14
E = 2.64 X 10^-19J
the answer is c, more heat is being released.
Answer:
Molality = 0.43 m
Explanation:
Given data:
Mass of barium sulfide = 25.4 g
Mass of water = 349 g (349 g/1000 = 0.349 Kg)
Molality of water = ?
Solution:
Number of moles of barium sulfide:
Number of moles = mass/molar mass
Number of moles = 25.4 g/169.39 g/mol
Number of moles = 0.15 mol
Molality:
Molality = number of moles o f solute/ Kg of solvent
Molality = 0.15 mol / 0.349 Kg
Molality = 0.43 m
