describe in your own words the structure of solid sodium chloride and explain why it is formula is NACL
Answer:
Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond. By the way, chloride is the term used to designate the anion form of chlorine. The result is a crystallized salt that has properties that are different from the two parent elements (sodium and chlorine). The chemical formula for sodium chloride is NaCl, which means that for every sodium atom present, there is exactly one chloride atom.

Which element in Fe(NO3) is a metal?
O
N
Fe
Answer:
Explanation:
Most periodic tables have a staircase thick line on their right side. This line separates the metals from the non metals.
O (oxygen) and N (nitrogen) are on the right side of the staircase.
Fe is on the left.
Those elements on the right side of the staircase are non metals.
Those elements on the left of the staircase are metals, so Fe is a metal.

The thermochemical equation for the formation of ammonia (NH3) is shown below. How much energy (kcal) is released when 6.0
mol of H2 reacts?
(Note - when the direction of energy flow is indicated, e.g. "released", the negative sign is not used in the answer.
3 H2(g) + N2(g) →2 NH3(g) triangleH = - 11 kcal
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.
Let's consider the thermochemical equation for the formation of ammonia.
3 H₂(g) + N₂(g) → 2 NH₃(g) ΔH = - 11 kcal
As we can see, 11 kcal are released when 3 moles of H₂ react. The heat released when 6.0 moles of H₂ react is:
[tex]6.0molH_2 \times \frac{(-11kcal)}{3molH_2} = -22kcal[/tex]
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.

Explanation:
Environmental factors can affect an organism's appearance, behavior, and health. For example, in certain reptiles, the temperature of the environment may determine the sex of the offspring. Both genetics and environmental factors determine the observable, physical characteristics of organisms, also called their _______________ in genetics.
a. phenotypes
b. organelle
c. morphology
d. genotype
Answer:
Phenotype
Explanation:
The observable physical characteristics of an organism, as determined by both genetic makeup and environmental influences.
The question is asking about the observable physical characteristics of organisms.
We can eliminate options B and C because they don't make much sense. An organelle is a structure in a cell which conducts cellular functions, and the morphology of an organism is basically the anatomy and physiology of the organism, which isn't quite what we're looking for.
Keeping this in mind, here is some information on prefixes:
geno - relating to genes
pheno - relating to what's observable
The second one sounds a lot like what we're looking for, and just in case, the definition of phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Therefore your answer is: A. phenotypes

Which of the three objects has the greatest density? Why? (GOLD BARS/GOLD COINS/GOLD CHAIN)
Answer:
They all have the same density
Explanation:
Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.
It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is [tex]19 \frac{g}{cm^3}[/tex].
Answerthey all have the same density Explanation:
How many cm of a solution of 0.100 mol dm NaOH are required to completely -3 neutralize 25.0 cm of 0.250 mol dm H3PO4?. a) Write a balanced equation for the reaction (4 marks) b) How many moles of H3PO4 need to be neutralized? (1 marks) c) How many moles of NaOH are needed to neutralize the H3PO4? (1 marks) d) How many cm of 0.100 mol dm NaOH contain the moles in question 5(©) above? (1 marks)
Answer:
Explanation:
How many cm of a solution of 0.100 mol dm NaOH are required to completely neutralize 25.0 cm of 0.250 mol dm H3PO4?.
a) Write a balanced equation for the reaction NaOH to neutralize (4 marks
?. ) 25.0 cm of 0.250 mol dm H3PO4
H3PO4 + 3NaOH----------> Na3PO4 +3 H2O
b) How many moles of H3PO4 need to be neutralized? (1 marks)
25.0 cm3 of 0.250 mol dm3 H3PO4: 1 liter has 0.25 moles. 100 ml has 0.025 moles 25 ml has o.025/4 molea or 0.00625 moles)
c How many moles of NaOH are needed to neutralize the H3PO4? (1 marks)
for every moles of H3PO4, WE NEED 3 MOLES OF NaOH. FOR 0.00625 MOLES WE NEED 3X 0.00625 =0.01875 MOLES OF NaOH
d) How many cm3 of 0.100 mol /l NaOH contain the moles in question 5(©) above? (1 marks)
1 L CONTAINS 0.100 Moles
100 ml contains 0.010Moles
we need 187.5 ml since (187.5 X 0.100)/1000=0.01875

Which substance tends to form anions when bonding with other elements?
sodium
oxygen
argon
calcium
Answer:
B) Oxygen
Explanation:
i just took the test.
Any species that contain negative charge over it called anion. Out of sodium, oxygen, argon and calcium, oxygen is the only element that can form anion. So option B is correct option.
What are non metals?Non metals are the element that have property to gain electron. When any element gain electron then element attain negative charge and that element is called anion.
In our question sodium, argon belongs to metals category and these lie on the left side of the periodic table. Metals are meant to release electron and hence become cation.
Argon is non metal but it is a noble gas which has property to not to react as its octet is complete. Thus the only element that is non metal here is Oxygen that forms anion. Its oxidation state is -2. Thus option b is correct option
