Does adding coefficients to a chemical equation disobey the law of define proportions?
No
How do you speed up a chemical equation?
adding heat using a catalyser
Is a chemical equation balanced by changing or adding?
The subscripts determine what the chemicals are, you have to change the amount of the reactants/products rather than change what the reactants/products actually are eg O2 is oxygen gas, if you wanted 4 of them to balance it it would have to be 2 O2 otherwise it wouldn't be oxygen gas any more.
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
Which one step is not a step used for balancing chemical equation?
Adding or removing atoms or molecules from the chemical equation is not a step used for balancing a chemical equation. The steps typically involved are: writing the unbalanced equation, balancing the atoms of each element, and adjusting coefficients to ensure mass is conserved.
Does adding coefficients to a chemical equation disobey the law of definite proportion?
No, adding coefficients to a chemical equation does not disobey the law of definite proportion. The coefficients simply represent the relative number of moles of each substance involved in the reaction and do not alter the proportion of elements present in the compounds.
Is adding water to lemonade physical or chemical change?
Physical because, the lemonade dissolves into the water, without creating any of the chemical changing results.
What are the ways rates of chemical change can be changed?
Rate of chemical change can be altered by 1. Changing the temperature. 2. Changing the pressure (if gases are involved). 3. Changing the particle size of a solid reactant. 4. Changing the concentration of a dissolved reactant. 5. Adding a suitable catalyst.
When balancing a chemical equation what do you adjust?
You adjust the coefficients in front of each molecule to balance the number of atoms on both sides of the equation. You should not change the subscripts within a molecule when balancing a chemical equation.
Can you count the number of atoms in a chemical equation?
Yes, you can count the number of atoms in a chemical equation by taking into account the subscripts of each element within the formula. The subscripts represent the number of atoms of each element present in the molecule. By adding up the total number of each atom on both sides of the equation, you can determine the total number of atoms in the chemical equation.
What is the word equation for adding copper(2) oxide to sulphuric acid?
The chemical reaction is:CuO + H2SO4 = CuSO4 + H2O
Is Ca plus CI2 - CaCI2 a balnced equation?
this can be trick balancing equations but this one is easy. the correct equation is CaCO3--> CaO+CO2. CaO plus CO2 does equal CaCO3 because you are adding the single Oxogen atom in CaO to the double Oxygen atom in CO2. basic maths makes it 1+2=3. Easy!!
