A double arrow shows that the reaction is reversible, it represents an equilibrium in which the products on the right can react together and produce the left hand side. A chemical equation without a double arrow isn't reversible and can only go in one direction.
A double arrow indicates a reversable or an equilibrium reaction.
It means that the reaction is reversible, such as that in the production of ammonia in the haber process
An equation with a one-way arrow indicates the the reaction occurs in one direction. An equation with an arrow pointing in both directions indicates that the reaction is reversible.
The chemical name is "methane" while the formula is "CH4".
An equation needs to be balenced to demonstrate the Law of Conservation of Mass, which states that in chemical reaction the total mass of the products is equal to the total mass of the reactants. This, simply put, means that what you start out with, you have to end with, even though it can be in a different order (making it (a) different substance(s) then what substance(s) you began with).
the weak chemical attraction is Hydroden bond while the stronger one is the Ionic bond
A change of state is a physical change while a chemical change is not
Co2 is the chemical name for carbon dioxide which is soluble in water, while Po43 is the chemical name for Phosphate,
In a chemical equation left hand side elements regarded as a Reactants , while right hand side is regarded as a products.
Lots of practice is needed. Not just mental practice, but written practice is needed.

Of course, equations are going to be studied in arithmetic while in elementary school. A different kind of equations will be studied in algebra and calculus in high school.
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
it must be cleared that while writing a chemical equation... it must be in symbols of that element then the numbers of the atoms used in the reaction must be equated to both the sides that is it must be equal to right hand side as well as left hand side... we need to remember the symbols of that element
A math equation uses variables and numbers, while a chemical equation uses compounds and mole ratios.

The chemical equations for the processes are opposites of each other. The chemical equation for photosynthesis is: solar energy + 6CO2 + 6H2O ---> C6H12O6 + 6O2 The chemical equation for cellular respiration is: C6H12O6 + 6O2 ---> 6CO2 + 6H2O + energy. The ONLY difference is that photosynthesis uses sunlight while cellular respiration produces energy in the form of ATP. :)
While it was common in some types of medieval warfare to use flaming arrows, it was uncommon to use them against human targets. Most often "Fire Arrows" were used to light structures and vehicles on fire.
The main difference in the equations is that electrical forces can be attractive or repulsive, while gravitational forces are always attractive.
