Answer:

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

7. What is the molarity of the nitrate ion that is found in a solution made by dissolving 6.25g
tekilochka [14]

Answer:

0.271 M NO₃⁻

Explanation:

To find the molarity of the nitrate ion (NO₃⁻), you need to (1) convert grams to moles (via molar mass), then (2) convert moles Al(NO₃)₃ to moles NO₃⁻, then (3) convert mL to L, and then (4) calculate the molarity. When (Al(NO₃)₃) dissolves in water, it dissociates into 3 nitrate ions. The final answer should have 3 sig figs.

(Steps 1 + 2)

Molar Mass (Al(NO₃)₃): 26.982 g/mol + 3(14.007 g/mol) + 9(15.998 g/mol)

Molar Mass (Al(NO₃)₃): 212.985 g/mol

1 Al(NO₃)₃ = 1 Al³⁺ and 3 NO₃⁻

6.25 g Al(NO₃)₃            1 mole               3 moles NO₃⁻
-------------------------  x  -----------------  x   -----------------------  =  0.0880 moles NO₃⁻
                                    212.985 g         1 mole Al(NO₃)₃

(Steps 3 + 4)

325.0 mL / 1,000 = 0.3250 L

Molarity = moles / volume

Molarity = 0.0880 moles / 0.3250 L

Molarity = 0.271 M

Many metals undergo a single displacement reaction with hydrogen chloride (a strong acid, HCl). One example is magnesium, Mg. Th
Vesnalui [34]

Answer:

Mg(s) + 2HCl(aq) →  MgCl2(s) + H2(g)  

Explanation:

Many metal undergo displacement reaction . The most reactive metal will displace the less reactive metal from it compound.  A single displacement reaction is a reaction in which one element displaces another in it compound.

Many metal undergo displacement reaction with hydrogen chloride . One example is magnesium. Magnesium will  displace hydrogen in hydrogen chloride because it is more reactive than hydrogen. The displacement reaction is as follow

Mg(s) + HCl(aq) →  MgCl(s) + H2(g). The balanced equation with the simplest whole number ratio is as follows

Mg(s) + 2HCl(aq) →  MgCl2(s) + H2(g)

How do you separate oil from water?
borishaifa [10]
To separate oil from water, add a solution of soluble ionic salt to the solution. Distillation, which involves boiling and condensing the water, is another option, as well as partially freezing the oil and water combination and discarding one-fourth to one-third of the unfrozen water.

What can cats get from eating mice and moles?
Nadya [2.5K]

Answer:

its called Toxoplasmosis.

Explanation:

Cats become infected by Toxoplasma gondii by ingesting the cysts of this parasite. Most often, this occurs when cats eat mice or rats infected with the parasite. However, they can also ingest it during grooming after coming in contact with infected soil or feces.

hope it helped ;)
