Can the arrow in chemical equation indicate which compounds have greater mass?

No, the arrow indicates which way the reaction proceeds, often with 2 arrows being used pointing in both directions indicating the reaction is in equilibrium. The compound's mass can be calculated using the molecular mass of the compound from the periodic table.

How is a catalyst like platinum different from an enzyme?
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
What statements must be true of an equation before you can use the quadratic formula to find the solutions?
That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.
What are some compounds that contain an alkali metal?
An alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases (compounds with pH greater than 7) that dissolve in water. chemical compound is a substance consisting of two or more elements chemically bonded together in a fixed proportion by mass
Which one out of N2 and NH3 have greater value of a and which one will have greater value of b?
In vanderwaal's Equation 'a' measures the intermolecular force of attraction and 'b' measures the volume of the molecule. N2 has greater volume (due to it's larger size) and hence 'b' is greater for N2. NH3 has greater dipole moment and hence 'a' is greater for NH3.
What is the change of enthalpy associated with the combustion of one mole of pentane The chemical equation is C5H12 8 O2 yields 5 CO2 6 H2O?
The enthalpy associated with pentane is roughly 1 to 1 when combustion in a vacuum chamber, if you combustion it outside you will have a greater rate of loss from the pentane.
When you have a chemical change is the mass of what you start with less equal or greater than what you end with?
If the equation is balanced, the mass will be the same on each side of the equation. Matter cannot be created or destroyed.
What does it indicate if the mean is greater than the standard deviation?
It does not indicate anything if the mean is greater than the standard deviation.
Can every element in the periodic table can be used to make compounds?
No, there are no known compounds of helium or neon, and theory suggests there are unlikely to be any such compounds. For some of the "artificial" elements with atomic number greater than 100 no compounds can be made, simply because the atoms undergo radioactive decay too quickly for any chemical characterisation or reaction.
Why ions with charges greater than 3 are seldom found in ionic compounds?
This is because the ionisation energy is too large for releasing the third electron to form chemical compounds or the electron affinity is too low for gaining the third electron when forming a chemical compound which will result in a low lattice energy to stabilise the ion.
When is b greater than 25 in this equation?
That depends on the equation and the question which have not been given.
What is the chemical equation for the reaction of acetic acid and potassium hydroxide?
Water, potassium and acetate ions. If you're adding equal amounts of both, the final solution will have a pH greater than 7.
What is a equation product greater than 1?
2*3 =
Can ionic compounds dessolve in water?
Ionic compounds can only be dissolved in water if the energy of hydration is greater than latice energy of that compound
What properties can be used to form ionic compounds?
electronegativity. the greater the difference in electronegativity of the elements the greater the likelihood of them forming ionic bonds.
How would you write a number plus three is greater than seven in a equation?
?+3(greater than sign) 7
What is the significance when the constant is greater than the universal gravitational equation?
There is no significance at all.
How is an equation different from an inequality?
In an equation, what is to the left of the equals sign equals what is to the right. In an inequality, the left side is either less than, greater than, less than or equal to, or greater than or equal to the right side.
