The circumstances that the system is exposed to may be altered in such a way as to cause a change in the chemical equilibrium. When we do this, we are said to be "stressing the balance."
In a chemical process that has reached equilibrium, one method is to either add or remove a product or a reactant. When more of a reactant is introduced, the equilibrium changes to alleviate the pressure, which results in the production of more products.
This is further explained below.
how and why this would change the pH of the solution.?Generally, When more product is introduced, the equilibrium moves away from products and toward reactants in an effort to lower the level of stress.
In the event that either the reactant or the product is withdrawn from the system, the equilibrium changes such that more of the corresponding substance is produced to compensate for the loss.
According to Ch/atelier's Principle, which claims that if a reaction in equilibrium is disturbed, the equilibrium will change to counterbalance that change, this indicates that if a reaction is in equilibrium, the equilibrium will alter to counteract that change.
If a solution has a large number of hydrogen ions, the pH of the solution will be low, and it will be classified as an acidic solution.
In conclusion, On the other hand, a solution is said to have a high pH and be in the basic state if it contains a low quantity of hydrogen ions in its composition.
The ratio of the concentration of hydrogen ions to the concentration of hydroxide ions is negative and inversely proportional.

How do ionic bonds form?
Quick
Answer:
Explanation: ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

to flow? (The gases do not act)

4.00 am
3.00
NE
2.00 am
2.00 L
A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.
We have 2 containers connected by a valve.
One container has a volume of 3.00 L and contains O₂ at 4.00 atm. The other container has a volume of 2.00 L and contains Ne at 2.00 atm.
When the valve is opened, the total volume is the sum of the 2 containers.
[tex]V_2 = 3.00 L + 2.00 L = 5.00 L[/tex]
Assuming constant temperature and ideal behavior, we can calculate the final pressure of each gas using Boyle's law.
O₂
[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{4.00atm \times 3.00L}{5.00L} = 2.40atm[/tex]
Ne
[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{2.00atm \times 2.00L}{5.00L} = 0.800atm[/tex]
The final pressure in the container will be the sum of the final pressures of the gases.
[tex]P = 2.40 atm + 0.800 atm = 3.20 atm[/tex]
A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

So what you want to do is to place sulfur on top with the two fluorine's on the bottom left and right hand side at slight angles. You don't want to make it look interconnected as one whole bond. Draw a single line from each "F" to the "S" to model two fluorine atoms bond to one sulfur atom (Single bond, only one electron is being shared between each).

What can you say about the reactants of photosynthesis and the products of cellular respiration?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Which are effects of long-term exposure to mustard gas? Select all that apply. One, some, or all responses may be correct.
The effects of long-term exposure to mustard gas causes mortality and chronic respiratory disease.
Exposure to mustard gas in the long term can result in mortality from influenza, pneumonia as well as chronic breathing disease. Exposure for long term leads to respiratory complications and septic shock. Extensive breathing in the environment of mustard gas can cause chronic respiratory disease, respiratory infections or death.
Extensive eye exposure to this gas can cause permanent blindness. Exposure to mustard gas may also increase the chances of lung and respiratory cancer so we can conclude that mustard gas is lethal and can cause a number of diseases in a person who is exposed to it.

EXPLANATIONA water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds
ADDITIONAL INFORMATIONHow to differentiate between ionic and covalent bonds ?
There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
