Answer:
The answer to your question is letter D.
Explanation:
A. Has a fixed volume This is not the right answer, liquids and gases take the shape of the container in which they are.
B. Particles stay in a fixed position This answer is wrong, this characteristic is of solids but not of liquids and gases.
C. No particle movement This characteristic is also of solids, in liquids and gases the particles can move.
D. Takes the shape of the container. This is the right answer, liquids and gases take the shape of the container.
if i am correct it shall be 12. because i am thinking, 1 mole = 1 ar.
Answer:
The Answer should be Endothermic reaction
Explanation:
Reactions in which energy is absorbed are called Endothermic reactions.
Balance Chemical Equation,
2 CO + O₂ → 2CO₂
Acc. to this reaction,
88 g (2 mole) of CO₂ was produced when = 56 g (2 mole)of CO was reacted
So,
24.7 g of CO₂ will be produced by reacting = X g of CO
Solving for X,
X = (56 g × 24.7 g) ÷ 88 g
X = 2.26 g ÷ 88 g
X = 0.0257 g of CO
Result:
0.0257 g of CO is required to be reacted with excess of O₂ to produce 24.7 g of CO₂.
The balanced half reactions are
4 Fe2+ ====> 4 Fe3+ + 4 e-
<span>MnO42- + 8 H+ + 4 e- ===> Mn2+ + 4 H2O
The net ionic equation is
4 Fe2+ + </span>MnO42- + 8 H+ ===> 4 Fe3+ + Mn2+ + 4 H2O<span />
