what is the correct equation for the reaction of HBr with Ca(OH)2-
It yields CaBr2 + H20
you balance it.
The correct equation for the reaction of HBr with Ca(OH)2 can be represented as follows:
2 HBr + Ca(OH)2 ⟶ CaBr2 + 2 H2O
In this reaction, two molecules of hydrobromic acid (HBr) react with one molecule of calcium hydroxide (Ca(OH)2) to produce one molecule of calcium bromide (CaBr2) and two molecules of water (H2O).
To determine the correct equation for the reaction of HBr with Ca(OH)2, we need to remember that acids react with bases to form a salt and water.
Step 1: Write the chemical formula for HBr (hydrobromic acid) and Ca(OH)2 (calcium hydroxide).
HBr: Hydrobromic acid consists of hydrogen (H) and bromine (Br).
Ca(OH)2: Calcium hydroxide contains calcium (Ca), oxygen (O), and hydrogen (H) in the form of hydroxide ions (OH-).
Step 2: Determine the products of the reaction. When HBr reacts with Ca(OH)2, the H+ ions from HBr combine with the OH- ions from Ca(OH)2 to form water (H2O). The remaining ions (Br- and Ca2+) combine to form calcium bromide (CaBr2), a salt.
Step 3: Write the balanced chemical equation using the formula of the reactants and products.
The equation should be:
2HBr + Ca(OH)2 → CaBr2 + 2H2O
This equation shows that two moles of hydrobromic acid (HBr) react with one mole of calcium hydroxide (Ca(OH)2), producing one mole of calcium bromide (CaBr2) and two moles of water (H2O).
acid + base = salt + water
2HBr + Ca(OH)2 ==> CaBr2 + 2H2O
