Answer:
Molality is 0.40 m
Explanation:
Molality is a sort of concentration that indicates the moles of solute dissolved in 1kg of solvent.
To determine molality we need the moles of solute, and the mass of solvent in kg so:
We convert the mass of solvent from g to kg:
740 g . 1kg/1000g = 0.740 kg
We know the moles, so we can determine molality
Molality (mol/kg) = 0.295 mol/ 0.740kg = 0.40 m
Answer:
34- Solid
35-Metals form metallic bonds releasing one or more valence electrons to form a common electron reservoir which contains free mobile elactrons who will conduct electricity well.
36 When the cation is formed electrons are removed and the effective positive neuclear charge increases and it makes the remaining electrons accumulate around the neucleous making the cationic radius smaller than that of the atom
I believe the end result is still 83 moles since there is never an amount of sulfur atoms added to the initial amount, but rather oxygen and water is repeatedly added to it. To find it's weight, first find the molar mass of H2SO4:
H2 + S + O4 = 2.00 + 32.1 + 64.0 = 98.1 g/mol
and mass = (98.1 g/mol)(83 mol) = 8142.3 g
rounded to 8.1 x 10^3 g assuming 100% yield?
Answer:
Aye bro you from discovery too
Explanation:
Answer:
BaCl2-- Barium dichloride✔️, the dash (-) has the problem.
Fe2O3-- Iron(iii)oxide✔️, it's not Iron(ii)oxide.
CsNO2-- it's Cesium nitrogen dioxide✔️, not Cesium nitrate.
Mg(HCO3)2-- Magnesium hydrogen carbonate✔️, not magnesium(II) bicarbonate
