Answer is: 48,25 torr.
Raoult's Law: p = x(solv) · p(solv)
p - <span>vapour pressure of a solution.
</span>x(solv) - <span>mole fraction of the solvent.
</span>p(solv) - <span>vapour pressure of the pure solvent.
</span>n(ethanol) = 950g ÷ 46,07g/mol = 20,62 mol.
x(solv) = moles of solvent ÷ total number of moles
x(solv) = 20,62 ÷ 21,77 = 0,965.
p = 0,965 ·50,0 torr = 48,25 torr.
Answer:
Light , heat , and sound are examples.
When someone pees in the pool this can cause the PH to change and when you put other chemicals in the pool, this can also change the PH in the pool.

Answer:
3 I'm in college so I know this stuff my guy
Explanation:
sus
Answer:
Antimony - metalloid
Tungsten- Transition metal
Argon - Noble gas
Iron - Transition metal
Bromine- Halogen
Cesium- Alkali metal
Cerium- lanthanide
Uranium - Actinide
Calcium- Alkaline earth metal
Lithium - Alkaline metal
Explanation:
Lithium is an alkaline metal because it belongs to group 1 of the periodic table. This is the general name for the group.
Calcium is an alkaline earth metal as it belongs to group 2 of the periodic table. This is the general name of the group.
Uranium is an actinide as it belongs to the second series of the f block
Cerium is the second element in the lanthanide series after lanthanum
Cesium belongs to group 1 and hence is an alkaline metal.
Bromine is a halogen as it belongs to group 7 of the periodic table
Iron is a transition metal as it belongs to the first series of transition metals
Argon is s noble gas as it belongs to group 18
Tungsten is s transition element and it belongs to the third series
Antimony is a metalloid
