Electromagnetic radiation is a form of energy that propagates as both electrical and magnetic waves traveling in packets of energy called photons. There is a spectrum of electromagnetic radiation with variable wavelengths and frequency, which in turn imparts different characteristics.
This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. ...
Answer: A weak acid titrated by a strong base
Explanation:
The graph refers to the titration of a weak acid such as Hydrofluoric acid with a strong base such as Sodium Hydoxide. What happens is that as the process begins, the pH rises quickly as there is little resistance to the base.
After some time the solution formed begins to act as a buffer between the remaining acid and the base. This reduces the pH change rate and will continue until the base overcomes the solution's buffering capacity.
The Equivalence point which is where the acid will be at it's base form, will be at a pH of 8.6.
I have attached a graph showing the process for better understanding.
Answer:
Density = 25.2 g/20.0 ml = 1.26 g/ml
57 ml x 1.26 g/ml = 71.8 g
Answer: OK so Natural resources are not evenly distributed all over the world. Some places are more endowed than others — for instance, some regions have lots of water (and access to the ocean and seas). Others have lots of minerals and forestlands. Others have metallic rocks, wildlife, fossil fuels, and so on.The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth. Hope this helps have a nice night❤️
