The total number of matchbooks required would 5,000 be and the cost would be $144
<h3>Mathematical ratios</h3>
50 matchbooks = $1.44
Each matchbook = 0.005 grams red phosphorus
25 grams of red phosphorus is needed:
25/0.005 = 5,000 matchbooks
5,000 matchbooks will cost:
5000/50 x 1.44 = $144

Answer:
2NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Explanation:
Knowing the names gets us: NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Balance: there are two sodiums and cyanides on the product side so add a 2 to the reactant side.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. I think its B
<h2>Answer with Explanation</h2>
This hypothesis concludes that the sugar dissolves faster in warm solution has to do with increased molecular motion because the combined power in the warm solution makes molecules in water to travel quicker and sucrose molecules to fluctuate faster which produced a continued evolution favors to make the connections between sucrose molecules easier to succeed. The collisions between the water molecules and the sugar molecules are at a high rate due to increased temperature.
Answer:
18 molecules of ATP will be produced for the breakdown of methionine to succinyl CoA and the entry of succinyl CoA to the citric acid cycle with no input of glucose.
Explanation:
Reactions reduced co enzymes ATP formation
α keto glutarate to propionyl CoA 2 NADH 6 moles
Succinyl CoA to succinate 2 GTP≈ 2 ATP
Succinate to fumarate 2FADH2 4 moles
Malate to oxaloacetate 2 NADH 6 moles
