Answer: B
Nitrifying bacterium, plural Nitrifying Bacteria, any of a small group of aerobic bacteria (family Nitrobacteraceae) that use inorganic chemicals as an energy source.
Answer:
3 moles of CaO
Explanation:
The chemical balanced equation is;
2Ca + O₂ → 2CaO
The ratio of calcium(Ca) to Calcium Oxide(Cao) in this equation is 2:2.
Now, when 3 moles of calcium react with oxygen, Cao produced will be;
3 moles of O₂ × 2 moles of CaO/2 moles of Cao = 3 moles of CaO
Work allows energy to be transferred from one object to another. To do work, an agent must exert a force on an object over a long distance.
When work is done, energy is transferred from the agent to the object, resulting in a change in the motion of the object (more specifically, a change in the object's kinetic energy).
What is energy?
Energy is essential to human society and has numerous health benefits. However, each energy source poses some health risks. This article examines the health consequences of each major source of energy, focusing on those with the greatest global impact on disease burden. The harvesting and burning of solid fuels, coal, and biomass have the greatest health consequences, primarily in the form of occupational health risks and household and general ambient air pollution. In the world's poorest households, a lack of access to clean fuels and electricity poses a particularly serious health risk. Although energy efficiency has many advantages, energy use is essential to human society and has numerous health benefits.
