A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
Answer:
The answer to your question is: letter A
Explanation:
a) A + B ⇒ AB + heat It is an exothermic reaction because heat is released.
b) A + BΔ ⇒ AB It heat added to the reactants , then it is an endothermic reaction.
c) heat + BC ⇒ B + C It's an endothermic reaction because heat is added to the reactants.
d) B + heat + CD ⇒ BD + C It's and endothermic reaction because heat is added to the reactants.
mass of Cl₂ = 8.61 grams
Explanation:
We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.
number of moles = volume / 22.4 (L / mole)
number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Cl₂ = 0.123 × 71 = 8.61 grams
