Answer:
Dalton's law is fulfilled, since the elements in each compound of the example are related to each other in different proportions forming two different compounds; so for case a) and b) you have 15.54% and 9.323% P respectively for each compounds, that are equivalent to 0.2912 g P for every g Cl and the other produced 0,1747 g P for every g Cl.
Explanation:
Dalton's Law ( law of multiple proportions):
When two or more elements combine to give more than one compound, a variable mass of one of them joins a fixed mass of the other, and the first is related to canonical and indistinct numbers.
a) for the compounds A:
⇒ 0.2912 g P / gCl * ( 35.45 g CL / mol CL) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.1554 g P / g PCl
⇒ % P = 0.1554 * 100 = 15.54 %
b) for the compunds B:
⇒ 0.1747 g P / g Cl * ( 35.45 g Cl / mol Cl ) * ( mol Cl / mol PCl ) * ( mol PCl / 66.427 g PCl ) = 0.09323 g P / g PCl
⇒ % P = 9.323 %
Answer:
3. atoms, ions, or molecules
Explanation:
A crystal is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Hope this helps!
Answer:
The heat capacity of the calorimeter or of the reaction mixture may be used to calculate the amount of heat released/absorbed by the chemical reaction. The amount of heat released or absorbed per gram or more of the reactant can then be calculated from the mass of the reactants.
-Quinn
Answer:
16kg/s
Explanation:
The formula for acceleration is [ a = f/m ] where f = force and m = mass
a = 4/0.25
a = 16
Best of Luck!
