The patient needs to receive 285.71 ml.
1000 ml contains 70 gr of glucose.
x contains 20 gr of glucose.
x=1000*20/70
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 energy needed to vaporize 1.5 kg of aluminum amounts to 16.345 GJ. The heat of vaporization for aluminum is given as ΔHvap = 294000 kJ/mol. The mass of aluminum in this case equals 1.5 kg which converts to 1500 g. We can calculate the number of moles of aluminum using the formula: Mass of aluminum/(Molar Mass of aluminum). The Molar Mass of aluminum stands at 26.98 g/mol. Using this information, Number of moles calculates to 1500/26.98, which equals 55.6 moles. The total energy required can be expressed as the product of the heat of vaporization and the number of moles of aluminum, so the energy required calculates to 294000 × 55.6, resulting in 16345441.0675 kJ or approximately 16.345 GJ.
Pure water lacks sufficient ions to conduct electricity. However, when metals like iron, zinc, and copper are present in moist soil, they can instigate electrolysis, which necessitates excess energy due to limited water's self-ionization. Consequently, wet soil can carry current as long as there are positive and negative ions. Water ions travel from the anode (positive side) to the cathode (negative side) to be oxidized and generate electricity.
