An exothermic reaction is one that, through either light or heat, releases energy.
It can be expressed simply as:
reactants --> products + energy
The potential energy at the end of the reaction is always lower than at the beginning of the reaction.
An endothermic reaction is a reaction that absorbs energy from its surroundings.
It is essentially reactants + energy ----> products.
Hope this helps,

Answer:
The limiting reactant is NaC₂O₄ and the yield of this reaction is 69.52%.
Explanation:
NaC₂O₄ + UO₂(NO₃)₂ + 3H₂O → UO₂(C₂O₄).3H₂O + 2NaNO₃
m (NaC₂O₄) = 0.4031 g MW = 134 g/mol ∴ n = 3.0 mmol
m (UO₂(NO₃)₂) = 1.481 g MW = 396.05 g/mol ∴ n = 3.74 mmol
m (UO₂(C₂O₄).3H₂O) = 1.073 g MW = 412.094 g/mol ∴ n = 2.60 mmol
The limiting reactant is NaC₂O₄
The yield can be given by (2.60/3.74).100% = 69.52%
Answer:
just because of the air
Explanation:
big / the answer is volume stays the same
Whether it floats or sinks depends on how much the charcoal weighs and how much water is used in the experiment. If the object is heavier than the water, it will sink. If it is lighter, it will float.
