The general formula of an acid is HX where H+ acts as the cation while X can be a halogen (Cl-, Fl-, Br-, etc) and acts as the anion. There are also cases where X is an ion like SO42-, which brings two atoms of H in the formula. Strong acids dissociate completely while weak acids do not.
Answer:
Explanation:
iron is element number 26 this means that it has 26 number of electron and proton in its atomic structure so its atomic number is 26
Answer: 2.0 moles of oxygen are needed to completely react with 1.0 mole of CH4 as shown in the balanced equation.
Explanation:
Stoichiometry is a fundamental tool and skill to determine the relative quantities that the chemicals react with. it determines the quantity of one substance to a quantity of another substance or substances. Stoichiometry is relating of one chemical substance to another using a balanced chemical reaction is called stoichiometry. Also, it is very important to predict what will occur and how much is produced through knowing the coefficients of moles of reactants and products.
Mole s defined as the mass of the substance divided by its molar mass.
As shown from the balanced equation every mole of methane(CH4) needs to react with 2.0 moles of oxygen(O2) to produce 1.0 mole of carbon dioxide(CO2) and 2.0 moles of hydrogen peroxide(H2O2).
You would die. Nothing would work. Every single cell in your entire body would fail, and you would cease living in an instant.
Answer: 1) endothernic
2) Yes absorbed
Explanation:
Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and 
for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
