Ca(s) + 2H+(aq) + [ Cl-(aq) ] --> H2(g) + Ca2+(aq) + [ Cl-(aq) ]
So you would say that a Calcium atom has reacted with 2 hydrochloric acid molecules to produce Hydrogen gas (H2) and calcium chloride in a quantitative reaction. (Chloride ion [ Cl-(aq) ] is not changed, it is called a 'tribune' ion)
2 HCl + CaCO3 -> CaCl2 + H2O + CO2 In words, two moles of hydrochloric acid reacts with one mole of calcium carbonate to yield one mole of calcium chloride, one mole of water, and one mole of carbon dioxide.
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
Here is the BALANCED symbol reaction Eq'n. 2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g) In words; Two moles of hydrochloric Acid (HCl) reacts with one mole of calcium carbonate (CaCO3) to produce one mole of calcium chloride(CaCl2), one mole of water(H2O), and one mole of carbon dioxide(CO2). Further symbols ;- (aq) = aqueous ( in solution). (s) = solid (l) = liquid NB for all acid and carbonate reactions, the products are a 'salt' , water and carbon dioxide. (g) = gas.
First of all vinegar has the chemical name of Ethanoic(Acetic) acid, and its formula is CH3COOH. The BALANCED reaction eq'n is 2CH3COOH(aq) + CaCO3(s) = Ca(CH3COO)2(aq) + H2O(l) + CO2(g) In words ; Two moles of ethanoic acid(CH3COOH) reacts with one mole of calcium carbonate(CaCO3) to produce one mole of calcium ethanoate(Ca(CH3COO)2, one mole of water(H2O) and one mole of carbon dioxide(CO2). NB Vinegar's everyday name is acetic acid, however, in the modern IUPAC nomenclature it is 'Ethanoic Acid'.
Ge(s)+2Br2(L)-->GeBr4(s) In other words, Germanium is a metal and reacts with bromine, which is liquid at standard temperature and pressure, to form solid Germanium Bromide. Hope this helps.
2 HCl + CaCO3 -> CaCl2 + H2O + CO2 In words, two moles of hydrochloric acid reacts with one mole of calcium carbonate to yield one mole of calcium chloride, one mole of water, and one mole of carbon dioxide.
. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
In words, this equation is carbon dioxide plus calcium hydroxide gives calcium carbonate plus water. The cloudiness is the calcium carbonate which appears as a solid. The symbol equation is CO2(g) + Ca(OH)2(aq) CaCO3(s) +H2O(l)
An equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are not the same for both the reactants and the products. In other words, the mass and the charge are not balanced on both sides of the reaction. This is also called as a unbalanced equation.
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
Magnesium metal with hydrochloric acid produces magnesium chloride with hydrogen gasThe bolded words are the only new ones.
Here is the BALANCED symbol reaction Eq'n. 2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g) In words; Two moles of hydrochloric Acid (HCl) reacts with one mole of calcium carbonate (CaCO3) to produce one mole of calcium chloride(CaCl2), one mole of water(H2O), and one mole of carbon dioxide(CO2).

If you write this as a balanced chemical equation, water will form as a result. You must account, in other words, for all the elements.
Ge(s)+2Br2(L)-->GeBr4(s) In other words, Germanium is a metal and reacts with bromine, which is liquid at standard temperature and pressure, to form solid Germanium Bromide. Hope this helps.
calcium bicarbonate is the opposite of calcium, even though it has the same word on both words!
A chemical equation may be written in a balanced form, showing the same number of atoms of each element on both sides, or in an unbalanced form, representing the reactants and products without considering conservation of mass.
