Acetylene gas, C2H2 (8). can be produced be reacting solid calcium carbide, CaCz, with water. The
products are acetylene and calcium hydroxide. What volume of acetylene gas is produced when
5.20 g of calcium carbide reacts with excess water at 25°C and 715 torr? Since it's collected over
water, don't forget to subtract the water vapor pressure of 23.8 torr.

What is the formula for calcium iodide

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
