What is the theoretical yield (in grams) of potassium chloride when 2.500 grams of potassium metal are reacted with 2.000 grams of chlorine gas to produce potassium chloride. Do not type units into your answer. 4.2 2K(s) + Cl₂(g) 2KCI(s)
The Haber Process is used to produce ammonia (NH3) from nitrogen and hydrogen. This process was originally developed to produce ammonia for the production of explosives to be used by Germany in World War I. It has subsequently been used to produce ammonia for fertilizer. This reaction releases 92.2 kJ of energy for every mole of nitrogen consumed. N₂(g) + 3H₂(g) 16,464 2NH3(g) How much energy (in kilojoules) can be produced from the consumption of 5.000 kilograms of nitrogen?
What is the [NaNO3] (in mole/liter) of a solution made by mixing 2.00 grams of solid sodium nitrate with enough water to make a total volume of 50.0 mL? Do not type units into your answer. 0.46
What is the final concentration of sodium nitrate (in mole/liter) if 25.0 mL of the solution produced in the previous problem is diluted with 75.0 mL of water? Used the unrounded concentration from the previous problem. Do not type units into your answer. 0.0156
What is the final molarity of sodium nitrate if 50.0 mL of the solution produced in the previous problem is diluted with 50.0 mL of water? Used the unrounded concentration from the previous problem. Do not type units into your answer. 4.3
Commercial products commonly report concentration in terms of "percentage." Using this technique, a 1% solution is considered to have 1 gram of solute for 100 milliliters of solution, and a 2% solution is considered to have 2 grams of solute for 100 milliliters of solution, and so on. Clorox bleach claims to be 6.00% NaCIO. What is the molarity of NaCIO in Clorox bleach? Do not type units into your answer. 0.671
Cellulose, the major component of plant cell walls has an empirical formula of C6H1005. One of the largest known Redwood trees, The Lindsey Creek Redwood had a mass of 3.3 x 106 kilograms at the time (1905) it was uprooted and felled by a storm. Assuming trees are composed of 45 % cellulose, calculate the moles of carbon contained in the cellulose of the Lindsey Creek Redwood. 5.4
