Answer:
See below, please
Explanation:
Because the mole ratio
Now, at the beginning
Mole m(CH4) =4 mol, m(O2) = 5 mol
If O2 gas is fully reacted, used up,
Need m(CH4) = 2.5 mol
Hence, the mole of CH4 left
m(CH4) = 4-2.5=1.5 mol
That means
At the end of the reaction,
m(CH4) =1.5 mol
m(O2) = 0 mol
Molarity is equal to the moles of solute over liters of
solvent. In getting the molarity of HCl, you must know the formula for two
solutions which is equal to M1V1 = M2V2. (2.00 M HCl)V1
= (20.0 milliliters) (1.00
M NaOH) and you have the volume of 10
millimeters of HCl.
In the diagram, an activity which is happening to the temperature at Point B is that: C. The temperature is not rising because the heat is being used to break the connections between the molecules.
<h3>What is matter?</h3>
Matter can be defined as any physical object or body that has both mass and takes up space. This ultimately implies that, the mass of a physical object measures the amount of matter the object contains.
<h3>What is heat?</h3>
In Science, heat is sometimes referred to as thermal energy and it can be defined as a form of energy that is transferred from a physical object (body) to another due to a difference in temperature.
By critically observing the diagram, we can reasonably infer and logically deduce that matter has dynamic states depending on the composition of its atoms and at point B the temperature remained constant (not rising) because the quantity of heat generated is used for breaking any form of connection between the molecules.

Protons and neutrons have similar mass. Electrons are smaller than a proton or a neutron. An atomic scientist was studying an atom and through experimentation found that the total negative charge of the area surrounding the nucleus is -9.
Energy flows into an ecosystem in the form of light and exits in the form of heat
