Ca + H2O = Ca(OH)2 + H2 is a Single Displacement (Substitution) reaction where one mole of Calcium [Ca] and two moles of Water [H 2 O] react to form one mole of Calcium Hydroxide [Ca(OH) 2] and one mole of Dihydrogen [H 2]

1 Ca + 2 H 2 O = 1 Ca(OH) 2 + 1 H 2 H is balanced: 4 atoms in reagents and 4 atoms in products. All atoms are now balanced and the whole equation is fully balanced:

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca (OH) 2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed with water. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide. [8]

在Ca 3 P 2 中，钙的氧化数为+2，磷的氧化数为-3。 识别氧化数的变化： 钙从0变为+2，失去2个电子（氧化）。 磷从 0 变为 -3，获得 3 个电子（还原）。 使用电子平衡变化：把Ca原子数×3，把P原子数×2 Multiply the number of calcium atoms by 3 and the number of phosphorus atoms by 2.

To balance Ca + H2O = Ca (OH)2 + H2 you'll need to be sure to count all of atoms on each side of the chemical equation. Once you know how many of each type of atom you can only change the...

There are three main steps for writing the net ionic equation for Ca + H2O = Ca (OH)2 + H2 (Calcium + Water). First, we balance the molecular equation. Second, we write the states and...
