Answer:
balances and scales, measurement transducers, vibrating tube sensors, Newtonian mass measurement devices and the use of gravitational interaction between objects.
Explanation:
C. water, because H2O is certain, and all those other things vary with location and climate
If you mean 4 moles per litre then:
In 1 litre there is 4 moles, therefore in .25 litres there is 1 mole.
1 mole of Magnesium Chloride would produce 2 moles of chloride ions (MgCl2 can also be written as Mg1Cl2, which dissolves to produce 1Mg(2+) and 2Cl(1-) ions: a 1:2 ratio)
So the answer is 2 moles of Chloride ions.
Answer:
copper cathodes are normally referred to when talking about copper. Cathode is the purest form of copper and is the feedstock used to produce copper wire, cable, sheet, strip, tube, etc.
Explanation:
<u>Answer:</u> The given electronic configuration is long hand notation.
<u>Explanation:</u>
Long-hand notation of representing electronic configuration is defined as the arrangement of total number of electrons that are present in an element.
Noble-gas notation of representing electronic configuration is defined as the arrangement of valence electrons in the element. The core electrons are represented as the previous noble gas of the element that is considered.
The given electronic configuration of potassium (K): 
The above configuration has all the electrons that are contained in the nucleus of an element. Thus, this configuration is a long-hand notation.
