This is one of the explanations I could think of,
Many reactions are incomplete and the reactants are not completely converted to products. Understandably due to loss in the process or inefficiency of the chemical reaction
Physical conditions like temperature and pressure affect state of matter. ... When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
Answer:
0.15 L= 150 ml
Explanation:
barium choride = BaCl₂
0.51 M = 0.51 mol BaCl₂/ 1 L solution
1 mol is equal to 1000 times a mmol:
0.51 mol = 0.51 x 10³ mmol= 510 mmol
As you know that the solution has 510 mmol BaCl₂ per liter, you can use the following simple calculation to obtain the volume in which there are 75 mmol BaCl₂:
510 mmol BaCl₂ ------ 1 L
75 mmol BaCl₂--------- X
X=
= 0.147 L ≈ 0.15 L
Answer:
185 gms o NaBr
Explanation:
Na Br mole weight = 22.989 +79.904 = <u>102.893 gm/mole</u>
1.083 x 10^24 molecules / 6.022 x 10^23 molecules / mole = <u>1.798 moles</u>
102.893 * 1.798 = 185 gms
