Answer:
There is no chemical symbol for paper since it is not an element but rather a mixture of several different compounds. Mixtures in two or more phases are heterogeneous mixtures.
Explanation:
<span>The most efficient way to determine whether a reaction is an exothermic chemical reaction is to use a temperature probe.
Given that an exothermic chemical reaction is going to release heat, using an instrument such as a thermometer or a temperature probe to see the change in temperature would be the best way in order to determine the type of the chemical reaction.

1031.9 K is the the kelvin temperature required for 0.0140 mol of gas to fill a balloon to 1.20L under 0.988 atm a pressure.
Explanation:
Data given:
number of moles of the gas = 0.0140
volume of the balloon= 1.20 litres
pressure of the gas = 0.988 atm
Kelvin temperature =?
R = 0.08206 L.atm/mole K
Formula used of ideal gas Law:
PV = nRT
putting the values in the equation after rearranging it:
T =
=
T = 1031.9 K
In the equation when the pressure is in atm, volume in litres, Gas constant has a value of 0.08206 L.atm/mole K and number of moles as moles the temperature unit is in Kelvin.
Answer: Here are the complete options.
A spontaneous process is one that occurs very quickly. A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium. A spontaneous process is one that occurs without continuous input of energy from outside the system. A process is spontaneous if it must be continuously forced or driven.
The correct option is
A spontaneous process is one that occurs without continuous input of energy from outside the system.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium
Explanation:
spontaneous process is one that occurs without continuous input of energy from outside the system and occur on its own because spontaneous processes are thermodynamically favorable characterized by a decrease in the system's free energy, they do not need to be driven by an outside source of energy. Which means that the initial energy is higher than the final energy.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium which will result to The sign of ΔG will change from positive to negative (or vice versa) where T = ΔH/ΔS. In cases where ΔG is: negative
Answer:
Jenna should: Verify the data by running the experiment several more times
Explanation:
Verifying your data can be done by running multiple trials to ensure that the results that come out was not due to other errors such as calculation mistakes, procedural errors, and the like. This will rule out other extraneous factors that could have unintentionally influenced the outcome of the experiment.
