To solve this questions you first need to find the number of moles of barium phosphate you have. The molar mass of barium phosphate is 601.93g/mol.
24.4/601.83 = 0.0402 moles barium phosphate
Then you need to use avagadro’s number, 6.022 x 10^23, which is the number of molecules or formula units in a mole.
6.022 x 10^23 * 0.0402 = 2.42 x 10^22 formula units
Answer:
aplha particle is the answer
I think the correct answer from the choices listed above is option B. Polymerization is the process of forming c<span>omplex molecules by the bond formation between monomers. There are two types of this process which are the addition and condensation polymerization.</span>
Answer:
Electronegativity in group 1 decreases as we go from Lithium to Francium.
Explanation:
Electronegativity is defined as the tendency of an element to attract an electron pair towards itself.
In a group generally this tendency decreases from top to bottom as the size of the atom increases and hence the positive nucleus get far from the outer orbital.
In the same way group 1 elements i.e. from Lithium to Francium electronegativity decreases.
Answer:
Chemical formula of the precipitate is Fe(OH)₃
Explanation:
Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociates in water. Carbonate ions is a weak base and combines with water to form hydroxide ions (OH⁻), as follows
CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻
Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed together, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.
