β 11y agoThe first law of thermodynamics states that energy cannot be created or destroyed, only changed in form. As such, the balanced chemical equation is typically represented as ΞU = Q - W, where ΞU is the change in internal energy of the system, Q is the heat added to the system, and W is the work done by the system.

β 14y agoThere is no chemical equation for the first law of thermodynamics, which is that energy can be neither created nor destroyed. This is a more general principle than any chemical equation.
To balance a chemical equation with parentheses, treat the entire compound within the parentheses as a single entity. Balance the elements inside the parentheses first before balancing the rest of the equation. Remember to distribute the coefficients outside the parentheses to all elements within it.
One website where you can balance chemical equations is https://www.webqc.org/balance.php. It provides a user-friendly platform to input the chemical equation and automatically balance it for you.
First off, you decide the product (becomes easier after a while of doing chemistry). The product is H2O (water). O2+H2=>H2O, but this is not stochiometrically balanced, so you have to change the amount of H2O's on the right side of equation and then to balance the amount of hydrogens. If you add a 2 in front of both, you get O2 + 2H2 => 2H2O
To balance the combustion reaction for E-10, which contains 10% ethanol and 90% gasoline, first write the chemical equation for ethanol combustion: C2H5OH + O2 -> CO2 + H2O. Then, adjust the coefficients of each compound in the equation to ensure that the number of atoms of each element is the same on both sides of the equation.
To balance a chemical equation, start by counting the number of each type of atom on both sides. Adjust coefficients to make the number of atoms of each element equal on both sides. Begin by balancing elements that appear in only one reactant and one product, then proceed to balance the more complex molecules. Remember to preserve the law of conservation of mass while balancing the equation.
Jean Beguin was the first iatrochemist to balance a chemical equation.
balance the equation. calculate moles of product.
The first step in solving a stoichiometry problem is to balance the chemical equation to ensure the number of atoms of each element is the same on both sides.
The reactants should be written first in a chemical equation, followed by an arrow indicating the direction of the reaction, and then the products.

The first step in stoichiometry is to balance the chemical equation by ensuring that the number of atoms of each element is the same on both sides of the equation. This is essential for accurately determining the stoichiometry of a reaction.
To balance the chemical equation between hydrochloric acid (HCl) and sodium carbonate (Na2CO3), you first write the unbalanced equation: HCl + Na2CO3 -> NaCl + H2O + CO2. Then you balance the equation by ensuring the same number of each type of atom on both sides of the equation, which in this case would be: 2HCl + Na2CO3 -> 2NaCl + H2O + CO2.

To balance the reaction between H3PO4 and NaOH, first write out the chemical equation: H3PO4 + 3 NaOH -> Na3PO4 + 3 H2O Now, each element must have the same number of atoms on both sides of the equation for it to be balanced. Adjust the coefficients in front of each compound to achieve this balance.
To balance this chemical equation: KβCOβ + BaClβ β 2KCl + BaCOβ First, balance the cations on each side of the equation, then balance the anions. Then, make sure the number of atoms of each element is the same on both sides.
