Copper (II) Nitrate, Cu(NO3)2, Solution Reacts With Potassium Hydroxide, KOH, To Form A Blueprecipitate

Answers

Answer 1

Answer:

Copper(II) nitrate and potassium hydroxide are soluble ionic compounds, which implies that they dissociate completely when dissolved in water to produce ions. ... You can thus say that the balanced chemical equation that describes this double ... Cu(NO3)2(aq)+2KOH(aq)→Cu(OH)2(s)⏐⏐↓+2KNO3(aq).

In order to become a chemically stable ion, a neutral atom of sodium will _______.
A. lose one electron
B. lose two electrons
C. gain two electrons
D. gain one electron

Answers

Answer:

D. gain one electron

Explanation:

In order to become a chemically stable ion, a neutral atom of sodium will gain one electron. Therefore, the correct option is option D.

What is chemical stability?

Chemical stability in chemistry refers to a chemical system's thermodynamic stability. When a system reaches its lowest energy state or in thermodynamic equilibrium with its surroundings, thermodynamic stability occurs.

It could be a spontaneous process when the total number of atoms or molecules in a given shape is conserved despite the fact that individual particles or atoms change forms. In order to become a chemically stable ion, a neutral atom of sodium will gain one electron.

Therefore, the correct option is option D.

A solution of 0.220 g of KIO3 is prepared in 50 ml volumetric flask. 2.00 mL of this solution is pipetted into a beaker with 8.00 ml distilled water, to give 10 ml of diluted KIO3. To this, 10.00 mL of starch sulfite was added. What would be the initial concentration of IO3- in this final solution

Answers

Answer:

0.00044 g/mL

Explanation:

First, 0.220 g of KIO₃ are dissolved in 50 mL, so the concentration at this point is:

0.220 g / 50 mL = 0.0044 g/mL

Then 2.00 mL of this solution are added to 8.00 mL of water (final volume = 10.00 mL). We calculate the concentration of the resulting solution:

0.0044 g/mL * 2.00mL / 10.00mL = 0.00088 g/mL

Finally, to this 10 mL solution, another 10.00 mL were added. Thus the KIO₃ (or IO₃⁻) concentration is:

0.00088 g/mL * 10.00mL / 20.00mL = 0.00044 g/mL

What is law of conservation of mass?

According to law of conservation of mass the mass in isolated system can neither be created nor destroyed by chemical reaction and physical transformation but it transfer from one form to another.

When wood burn the mass of soot, gases and ashes is equal to the original mass of charcoal and the oxygen when it first created is one of the best example of law of conservation of mass.

Thus, Nieko purchases a box of granola cereal that has a mass of 0.312 kg, then according to law of conservation of mass, the mass of each group is 0.312 kg.

The pH scale which classifies a solution's acidity or basicity.

A pH below 7 is acidic. This means it has more hydrogen ions. A pH equal to 7 is neutral. This has equal hydrogen and hydroxide ions.A pH above 7 is basic. This has more hydroxide ions.

We are given a reading of 8. This is above 7, but not much greater. Therefore, it could be classified as a weak base.

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which line from the text most clearly explains the main idea of the first paragraph?Group of answer choices:Have you ever witnessed something amazing, shocking or surprisingHuman memories are really a mixture of many non-factual thingsHer brain may recall that the person was tall, but not be able to say how tallDocumented cases have shown eyewitnesses adding detail to testimony Fourteen school festival tickets were sold to adults and children.
