Answer: Yes, there is sufficient sodium carbonate available.
Explanation:
In this scenario, according to the specified reaction:
Using stoichiometry, one can figure out the grams of sodium carbonate required to neutralize 1,665 g of sulfuric acid as outlined below:
Hence, the amount on hand is 2.0 kg, which leaves 0.2 kg as surplus, therefore:
A. Yes, there is sufficient sodium carbonate available.
Best regards.
The answer is B. 45k. Human bodies contain approximately 60 to 70% water.
Answer:
Endothermic: water formation from ice and a cold instant ice pack Explanation:
In this scenario, the average cofactor mass for each cell is indicated as 77.91pg, and the total cell quantity is given as 10^5 cells. You need to calculate the total cofactor that will be present in those cells (where 1 microgram equals 10^6 picograms). The calculation follows:
Cofactor mass = cofactor per cell * total cell count = 77.91pg/cell * 10^5 cells = 7.791 x 10^6pg
Next, to convert picograms to micrograms: 7.791 x 10^6pg / (10^6pg/microgram) = 7.791 micrograms
