How about P-La-S-Ti-C W-Ra-P?
Answer:
Explanation:
1. Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3
2. FeSO4 + 2 NaOH = Fe(OH)2 + Na2SO4
3. Fe(NO3)3 + 3 NaOH = Fe(OH)3 + 3 NaNO3
For the second part of 3 since it tells us NaOH is excess we dont care about it. We use our balanced equation 3 to get the correct molar ratios to solve this.
1.5mol Fe(NO3)3 x 3mol NaNO3/1mol Fe(NO3)3 x 84.99gNaNO3/1molNaNO3
= 382.455g NaNO3
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:

The answer is B.
This is because the temperature can affect the rate of reaction. The higher the temperature, the more the molecules move and collide with one another. If the temperature is decreased, the molecules will move slower and not collide as much.
