The number of micrograms of contaminant each person will receive is 5,742.64 ug.

<h3>Number of micrograms of contaminant  per person</h3>

The number of micrograms of contaminant each person will receive is calculated as follows;

Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L

Amount of contaminant (mg) = 2.3028 mg.L/mL

Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg

Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug

<h3>Amount of contaminant per person (ug/person) </h3>

=  (2,302,800 ug) / (401 persons)

= 5,742.64 ug per person

when an electron moves from a higher orbit to a lower one does it always follow the same path explained​
Ilia_Sergeevich [38]

Yes, electron follows the same path when it absorb and loses energy.

Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.

While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

Each incomplete reaction is a neutralization reaction. Match each equation with the salt formed. 1. H2SO4 + 2NH4OH → ? 2. 2NaOH
sergey [27]

1. H₂SO₄ + 2NH₄OH ⟶ (NH₄)₂SO₄ + 2H₂O


2. 2NaOH + H₂CO₃ ⟶ Na₂CO₃ + 2H₂O


3. HNO₃ + KOH ⟶ KNO₃ + H₂O


<em>Explanation</em>:

Acid + base ⟶ salt + water


Take the H from the acid and the OH from the base to get water.


Then, join what’s left to get the salt. Write the symbol for the metal first.


For example, in equation 3, take the H from HNO₃ and the OH from KOH.


Combining the remaining parts (NO₃ and K) to get the salt, KNO₃.
