Which system is correctly paired with its function?

Which process adds carbon dioxide to the atmosphere? Photosynthesis Sedimentation Respiration Evaporation

Hatshy [7]

Photosynthesis: The process which is used by organisms and plants to convert light energy to chemical energy. This process, takes in the carbon dioxide which is produced by the organisms and adds oxygen again in the atmosphere.

Sedimentation: This process is used for the treatment of water by using to remove suspended solid particles or unwanted particles from water.

Respiration: The process in which intake of oxygen occurs and release of carbon dioxide takes place.

Evaporation: The process in which liquid state changes into gaseous state.

Hence, according to the definition of respiration, due to this process only carbon dioxide is adds to the atmosphere.

Thus, respiration is the correct answer.

Draw the salt produced in this reaction. include charges.

Svetach [21]

Since no equation is being given, I will explain how to balance a chemical reaction. The key in the balancing of chemical reaction is to make sure that you got the exact chemical formula of the substance that is reacting and the yielded product. After getting the formula, identify first the hardest element/atom to be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the atoms present in the molecule of the substance. For example Al(s) + HCl(aq) à AlCl3(aq) + H2(g). the hardest element here is the Cl. Observe that there are 3Cls in the product side so add 3 to the HCl. However, it would not balance the H2 in the product side so you increase the addition to AlCl3, add 2. Now you have 6 atoms of Cl, add this to the reactant side, you get 6HCl. Since you have 6Hs, add 3 to H2 (3 multiplied by 2 gives 6). Then Al has 2 atoms in the product side, add 2 to the reactant side. The balance chemical reaction is 2Al(s) + 6HCl(aq) à 2AlCl3(aq) + 3H2(g).

On a lab exam, you have to find the concentrations of the monoprotic (one proton per molecule) acids HA and HB. You are given 43

gavmur [86]

Answer:

0.1818 M

Explanation:

For the process of titration , the formula we use is -

M₁V₁ = M₂V₂

Where ,

M₁ = initial concentration of the acid

V₁ = initial volume of the acid

M₂ = final concentration of the base

V₂ = final volume of the base

Hence , from the question ,

The given data is ,

M₁ = ?

V₁ = 43.5 mL

M₂ = 0.0906 M

V₂ = 87.3 mL

Now, to determine the unknown quantity , the formula can be applied ,

Hence ,

M₁V₁ = M₂V₂

Putting the respective values ,

? * 43.5 mL = 0.0906 M * 87.3 mL

solving the above equation ,

M₁ = ? = 0.1818 M
