T<span>he balanced reaction is as follows;
Ca(OH)</span>₂<span> + 2HCl ---> CaCl</span>₂<span> + 2H</span>₂<span>O
stoichiometry of Ca(OH)</span>₂<span> to HCl is 1:2
number of moles of Ca(OH)</span>₂<span> reacted = 0.120 mol/L x 0.0240 L = 0.00288 mol according to molar ratio of 1:2 number of HCl moles reacted = twice the number of Ca(OH)</span>₂<span> moles reacted
number of HCl moles reacted = 0.00288 mol x 2 = 0.00576 mol
number of HCl moles in 160 mL - 0.00576 mol
therefore number of HCl moles in 1000 mL - 0.00576 mol / 160 mL x 1000 mL = 0.036 mol
molarity of HCl = 0.036 M</span>
Answer: Compound
Explanation: pure substance that cannot be broken down into simpler substances by chemical or physical means. Each element has unique physical and chemical properties.
Aretes and horns
Explanation:
Aretes and horns are the landforms that are created where cirques meet. These landforms are products of glacier erosion in most temperate and polar regions.
- Cirques are common products of alpine glacier erosion.
- They arise in form of bowl shaped hollows on the side of a mountain.
- These hollows joins to form a U-shaped valley called Aretes and unique pointed arcs known as horns.
