Answer:
im not sure, are you sure?
Answer: I believe the correct answer is C. 41 degrees Fahrenheit.
Explanation: Time and temperature are the most essential elements for monitoring the growth of disease-causing bacteria in food. The temperature danger zone lies between 40 degrees Farenheit and 140 degress Fahrenheit.

A perfect gas, commonly known as an ideal gas, would be a gas that, in physical behavior, conforms towards the general gas law, which would be a <u><em>specific, idealized relationship between pressure, volume, and temperature,</em></u> and further calculation can be defined as follows:
For question a:

The answer to number 11 is 76.04 g!! I have attached a picture showing you my work. You want to go from mass to moles, so i first wrote down the info that we know- 2.00 mol. I then determined the mass of H2O2 in one mol
I did this by looking at the periodic table and looking at the atomic mass (bottom number) for each element and it’s quantity.
I then multiplied 2.00 by 38.03 because the bottom number on the fence post (1 mol) cancels out! I hope this helps you!
Answer:
In the case of an exothermic reaction, the reactants are at a higher energy level as compared to the products, as shown below in the energy diagram. In other words, the products are more stable than the reactants. Overall Δ H ΔH ΔH for the reaction is negative, i.e., energy is released in the form of heat.
