All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
<h3>What is Endothermic reaction?</h3>
Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.
In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.
Therefore, All of the energy from the reactants will be lost to the surroundings.
The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.

Precise is the close proximity of repeated measurements. In order to be precise, you need two or more measurements.
Accurate is the close proximity to the real (or expected) measurement.
<u>For Example: </u>
You are at the grocery store buying watermelons. The sign says that the watermelons all weigh 2 lbs. You weigh 3 of them on the scale next to the watermelon display. Their weights are 1.77, 1.80, and 1.82.
→ The <u>scale is precise</u> because it weighs all 3 of them at nearly the same value.
→ The <u>scale is not accurate </u> because their weights are not close to the expected value of 2.0
You take one of the watermelons to the cashier. The scale at the checkout counter weighs it as 1.99. The scale at the checkout counter is accurate. You cannot determine the precision of the scale at the checkout counter because you have no other values to compare it to.
Answer: Precise CANNOT be determined by one measurement.
Accurate CAN be determined by one measurement.
Hi there!
Th' balanced chemical reaction :-
C₃H₈ + 5 O₂ —--→ 3 CO₂ + 4 H₂O
Follow th' steps :-
To calculate amnt. of C₃H₈
3.25 g C₃H₈ × 3 mol CO₂ × 44.00964 g CO₂ mol⁻¹
Divide th' above by :
44.0956 g C₃H₈ mol⁻¹ × 1 mol C₃H₈
The answer after calculations = 9.73 g CO₂
Hence,
9.73 g of CO₂ will be produced when 3.25 g C₃H₈ is consumed.
~ Hope it helps!
It does not affect the melting point but it might affect your ability to see the melting point
