Answer:
bro what Is this like I dont even kno
We can find the number of moles of PH₃ using ideal gas law equation
PV = nRTwhere
P - standard pressure - 101 325 Pa
V - volume - 250 x 10⁻⁶ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 273 K
substituting the values in the equation
101 325 Pa x 250 x 10⁻⁶ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 273 K
n = 0.011 mol
therefore mass of PH₃ = 0.011 mol x 34 g/mol = 0.374 g
mass of PH₃ is 0.374 g
Answer: Synthesis
0.84 moles of oxygen
25 moles of
Explanation:
The balanced chemical equation is:
This is a synthesis reaction as one product is formed by combination of two reactants.
According to stoichiometry :
a. 2 moles of require = 3 moles of
Thus 0.56 moles of require= of
b. 4 moles of give = 2 moles of
Thus 50 moles of give = of
My boy this is to easy it’s true
A concentrated acid<span> has a relatively large amount of solute dissolved in the solvent. A </span>dilute acid<span> has a relatively smaller amount of solute dissolved in the solvent. In a solution of a strong </span>acid<span> there would be solvated ions present, but no associated molecules present.</span>
