Answer:
7.01 mol CH4
Explanation:
STP means standard temperature and pressure, so they are basically telling you that the gas is at 1 atm and 273 K (0 degrees celsius). Now that we have the pressure, volume, and temperature we can use the ideal gas law and solve for n or moles
PV=nRT
n=PV/RT
n=(1)(157)/(0.08206)(273)
n=7.0081 (round to 3 sigfigs)
n=7.01 mol
H is positive 1 and o is negative 2 so 3+b-6=0 and solve for b to get b=3
Changes in the independent variable lead to changes in the dependent variable during an experiment.
<h3>What is the independent variable?</h3>
The dependent and independent variable
In experiments, two variables are necessary to derive the cause of one factor over the other. These are the independent and dependent variables.
The independent variable can be altered, manipulated and changed in an experimental study.
The effect of such manipulation is observed on another variable which is the dependent variable.
The dependent variable when changes such a change can be recorded to derive the outcome of the experiment.
Hence changes in the independent variable lead to changes in the dependent variable during an experiment.

Answer:
Electrons in a metal that aren't bonded with only one atom
Answer:
Explanation:
In this problem,
we will determine the enthalpy at the end of heat input and we get the condition is the super heated state.
so the entropy change will be due to latent heat at 150 kPa and also due to temperature change at the super heated state.
All the temperature, enthalpy is evaluated with the help of the steam table.
mass is calculated with the help of a specific volume at initial condition.
