You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ionic compounds, make a prediction for each compound.Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen
Answer:
Oil: covalent
Cornstarch: Covalent
Sodium chloride: Ionic
Sodium bicarbonate: Ionic
Explanation:
Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.
1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.
4. Sodium bicarbonate, whose formula is is formed by transfer of electrons from sodium to .Ionic compounds are soluble in water.

If you worked at a job for 9.00/hour, what type of correlation is the number of hours worked and your take-home pay?
Answer:
There is a linear correlation between the number of hours worked and take-home pay. And more exactly, a direct proportionality. [tex]C = 9\cdot t[/tex]
Explanation:
From statement we deduce that amount of hours worked ([tex]t[/tex]) (Independent variable, measured in hours) is directly proportional to take-home pay ([tex]C[/tex]) (dependent, measured in monetary units), since proportionality ratio is constant and, therefore, there exists a linear correlation between both variables. That is:
[tex]C \propto t[/tex]
[tex]C = k\cdot t[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in monetary units per hour. If we know that [tex]k = 9\,\frac{m.u.}{h}[/tex], then the resulting correlation is:
[tex]C = 9\cdot t[/tex]
There is a linear correlation between the number of hours worked and take-home pay.

Explanation:
im smart
Answer:
The longest duration between full moon to new moon (or new moon to full moon) lasts about 15 days and 14.5 hours, while the shortest duration between full moon to new moon (or new moon to full moon) lasts only about 13 days and 22.5 hours. New Moon appears higher on summer solstice than on winter solstice.

Use time and space relationships

=================
Selection:
These are in approximate order:
Hypothesize: Build an explanation of the observation. The hypothesis should be done after a thorough review of existing information. Library database searches and researcher interviews are suggested.Predict: prediction of what would happen if the explanation were correct. E.g., If an atom is homogenous and has no internal structure, then bombarding it with with neutrons will result in most neutrons going right through the atom, and none would be reflected backwards.Plan and conduct investigations: Design experiments that test the hypothesis. E.g., see if any neutrons are reflected backwards. If they are, the hypothesis needs to be changed.
Measure: Do the work. Calibrate the equipment and record everything.
Record and display data: Publish the results and conclusions for peer review. Seek other's input in order to generate general agreement that the data, procedure, and conclusions are warranted.
===
Use numbers? Nah. Not if they are not required to reach a conclusion.(e.g., the precipitate will be pink or the reaction will stink).
Use Time and Space Relationships: Yes, but only if the hypothesis depends on them.
Classify and Order: OK, especially if you are a biologist, but not always necessary.
Use variable: usually, but what and how depends on the experiment.
Blame: Place blame on the lab partner (Just kidding).

Which compound contains nitrogen with an oxidation number of +3?
Answer:
Nitrous Acid [tex]N_{2}O_{3}[/tex]
Nitrogen is in the +3 oxidation state in N2O3. Nitrous acid is a weak acid.
The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂. Nitrous acid is a weak acid.
What do you mean by oxidation state ?The term oxidation state is defined as the total number of electrons that an atom either gains or loses in order to produce a chemical bond with another atom. The oxidation state is also called as oxidation number.
The formula for calculating oxidation states would be : The Highest Oxidation State for a Transition metal = Number of Unpaired electrons + Two s-orbital electrons.
The compound contains nitrogen with an oxidation number of +3 is N₂O₃ because it can acquire three electrons to form a chemical bond and to complete its outermost orbit (octet).
Thus, The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂.

Both B and C
Answer:
C is the answer..
The equation is showing how it is formed, so the answer is on the other side of the equal sign.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, diagram C shows the final compound.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
