What mass of oxygen is required to completely react with 2 moles of ch4
Firlakuza [10]
The balanced reaction that describes the reaction between methane and oxygen to produce water and carbon dioxide is expressed CH4  + 2 O2 = CO2 +2H2O. Hence for 2 moles of methane used, 4 moles of oxygen are needed to react completely.

What is the percent rate of change in function y = \((0.99)^x\)? Determine whether the function represents exponential growth or
storchak [24]

Answer: The correct answer is 1%: exponential decay.

Explanation: We are given a function:

y=(0.99)^x   ...(1)

To determine the percentage rate of change in function, we compare the given function with the general form of exponent function, which is:

y=a(1+r)^x    ...(2)

Comparing both the equations, we get:

1+r=0.99

r=-0.01

We take 'r' in percentage, so converting this above value in percentage, we get:

r=-0.01\times 100=-1\%

As the value of 'r' is negative, it means that the exponent is decaying, so the percentage rate of change in function will be 1% and it will be exponential decay.

Read the lab procedure for a controlled experiment that looks at the effect of heat on the circumference of bicycle tires.
gavmur [86]

The last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).

<h3>What is an experiment?</h3>

The essence of an experiment is to be able to establish a cause and effect relationship. It is only when we carry out a carefully controlled experiment that we can say that x causes y because the data would support our findings.

After, we have carried out an experiment, the next step is to put the evidences together and then try to arrive at a logical conclusion for the experimental procedure.

Thus the last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).

The equilibrium-constant expression depends on the ________ of the reaction. Group of answer choices temperature stoichiometry m
slavikrds [6]

Answer:

temperature and mechanism

Explanation:

Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:

<h3>k=Ae^{\frac{-E_{a} }{RT} }</h3>

where k=equilibrium constant

          A=pre-exponential factor

          E_{a}=Activation energy

          T=temperature

          R=Universal gas constant

<h3>It is clear that k depends only on temperature and activation energy.</h3>

Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.
