B. Mixture, because the noodles, chicken, and chicken broth are mixed together.
Answer:
The procedure with the simple calorimeter to compare the energy released by different fuels is described below in detail.
Explanation:
If the response delivers heat (rxn < 0), then heat is consumed by the calorimeter (calorimeter > 0), and its temperature improves. Conversely, if the response consumes heat (rxn > 0), suddenly heat is carried from the calorimeter to the arrangement (calorimeter < 0), and the temperature of the calorimeter drops.
Answer:
y = -2.5 + x
Explanation:
Given the data:
__X____Y
$20 __$17.50
$21 __ $18.50
$22__ $19.50
$23__ $20.50
Using a linear regression calculator :
The linear regression model obtained is :
y = -2.5 + x
Where ; - 2.5 = intercept ; gradient / slope = 1
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat
Explanation:
When Sean cook meals with propane he use a combustion reaction:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat
When propane (C₃H₈) is reacted with oxygen (O₂) produces carbon dioxide (CO₂), water (H₂O) and heat.

I don’t know what the “cheater” way is, however you can easily judge how many valence electrons an element has by looking at its group number on the periodic table.
Bonding in chemistry is completely and totally due to electrons. Every element wants 8 electrons in its outer shell in order to be stable. This is what we call the “Octet Rule”.
