The balanced chemical equation is: CH4 + 2O2 -> CO2 + 2H2O. In this reaction, one molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.
How many grams of Cu(NO3)2 are needed to produce 1.00 L of a 0.500 M solution?
To make a 0.500 M solution of Cu(NO3)2, you'll need 0.500 moles in 1.00 L of solution. The molar mass of Cu(NO3)2 is 187.56 g/mol, so you would need 93.78 grams of Cu(NO3)2 to make 1.00 L of a 0.500 M solution.

A number placed in front of a chemial formula in a chemical equation is called?
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
Glucose + Oxygen -> Carbon dioxide + Water
This is the balanced chemical equation for the cellular respiration process in living organisms, where glucose and oxygen react to produce carbon dioxide and water, releasing energy that is vital for cellular processes.
Chemical equation for burning fossil fuels?
The general chemical equation for burning fossil fuels such as gasoline is:
(C_{n}H_{m} + O_{2} \rightarrow CO_{2} + H_{2}O + heat), where (n) and (m) represent the number of carbon and hydrogen atoms in the fossil fuel molecule, respectively.
Why is mass conserved in chemical equation?
Mass is conserved in chemical reactions because the total number of atoms of each element before and after the reaction remains the same. This means that no atoms are created or destroyed during a chemical reaction, only rearranged into different molecules. This principle is known as the law of conservation of mass.
2Li(s) + Br2(g) -> 2LiBr(s)
False. In a chemical equation, the total mass of the products is equal to the total mass of the reactants due to the law of conservation of mass. The mass of individual atoms may change during a chemical reaction, but the total mass remains constant.
P4 (s) + 6Cl2 (g) -> 4PCl3 (l)
What do Chemical equations show or describe?
Chemical equations show the reactants involved in a chemical reaction, the products formed, and the stoichiometry or proportions in which they react. They provide a concise way to represent what happens in a chemical reaction.

What is a subscript in a balanced chemical equation?
A subscript in a balanced chemical equation indicates the number of atoms of an element present in a molecule. It is a small number that appears at the bottom right of the element's symbol. Balancing the equation ensures that the number of atoms of each element is the same on both sides of the equation.
Carbon dioxide (CO2) belongs in the blank space of the chemical equation, as when fossil fuels burn, they produce carbon dioxide along with water and release heat as a byproduct. The balanced equation is typically represented as Fossil fuel + O2 + H2O + heat -> CO2 + H2O.
Ask us anythingWhat are state symbols in a chemical equation?
State symbols in a chemical equation indicate the physical state of the reactants or products. The common symbols are (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water). These symbols help provide more information about the reaction conditions.
The balanced equation for the reaction is: Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g).
To calculate the mass of HCl consumed, you need to know the molar mass of HCl (approximately 36.46 g/mol) and the molar ratio between HCl and Mg in the balanced equation (2 moles of HCl per 1 mole of Mg).
Once you have the moles of Mg given, you can use the mole ratio to calculate the moles of HCl consumed, and then convert that to mass using the molar mass of HCl.
Chemical equations written with symbols and formulas provide precision and clarity in representing the reactants and products involved in a reaction. They also allow for easy stoichiometric calculations and a more concise way of expressing chemical reactions.
What are the products of CO2 plus 2H2O plus energy?
The products of the reaction between CO2, 2H2O, and energy depend on the specific conditions. In the presence of chlorophyll and sunlight, the products could be glucose and oxygen through the process of photosynthesis. In other conditions, the products could potentially include carbon monoxide, hydrogen gas, and water through a process like the reverse water-gas shift reaction.
What is ka for h3bo3(aq) h plus (aq) plus h2bo3-(aq)?
The equilibrium constant expression for the reaction you provided would be ( K_a = \frac{[H^+][H_2BO_3^-]}{[H_3BO_3]} ). However, the specific value of ( K_a ) for this reaction would depend on the concentrations of the species involved in the particular experimental conditions.

A chemical equation for alkene reaction with bromine water in tetra chloride?
Alkene + Bromine water in tetrachloromethane (CCl4): CnH2n + Br2 -> CnH2nBr2
Why are chemical equations balanced?
Chemical equations are balanced to satisfy the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element present in the reactants must be equal to the number of atoms of the same element in the products. Balancing ensures that the reaction equation accurately represents the substances involved and the quantities of each element present.
