Answer: Y 21.38 % , Al 32.44 % and O 46.16 %
Explanation: Molar mass of YAl5O12 is 88.91 + 5·26.98+12·16
= 415.81 g/mol
m-% ( Y) = 88.91 / 415.81 = 21.38 % , m-% (Al) = 5·26.98 / 415.81 =
32.44 % , rest is Oxygen
Answer:
B) a prediction
Explanation:
It is not option A because an experiment is one or more tests to see the check of a phenomenon in certain circumstances.
The idea is to validate or refute a hypothesis.
It is not option C because one theory is based on many proven hypotheses.
The correct option is B, a prediction. It is the principle that will lead us to a theory.
329.10 g is the mass of 1.59 moles of Ca(ClO3)2
Reactivity. It is the ability of matter to combine chemically with other substances.
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
<h3>What is an optical activity?</h3>
An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.
<h3>What is malic acid?</h3>
Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is
. Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
<h3>The stereoisomeric forms of malic acid.</h3>
In Science, there are two (2) stereoisomeric forms of malic acid and these include:
