The molecular formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
(CH₂O)n = 150 g/mol
(12+2.1+16)n = 150
(30)n = 150
n = 5
Which of the following are held together by nonpolar covalent bonds? PLEASE HELP
Answer:
The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
C. Atoms of chlorine (CI)
A covalent bond is created when the electrons from the two involved atoms are shared equally.The pair of electrons involved in this kind of bonding is referred to as the shared pair or bonding pair. Here the atoms of chlorine have non-polar covalent bonds. The correct option is C.
What are non-polar covalent bonds?A non-polar covalent connection is created when atoms with an equal amount of electrons share one another. The electronegativity of the two atoms is equivalent. When two atoms with similar electron affinities join together, like in the case of diatomic elements, it happens.
Non-polar covalent compounds are those in which there is no variation in electronegativity. In these compounds, the electronegativity does not change, preventing the motion of the bond pair's electrons in the direction of the linked atoms.
As a result, a molecule is non-polar and non-conducting since there is no bond or dipole moment between its atoms and no buildup of charges on the atoms.
Thus the correct option is C.

Why is it that the decomposition of nitroglycerin can result in so
much more volume than the decomposition of sodium azide?
Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.
What is volume?A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, like the cubic metre or litre, or different imperial or US-standard units, including the gallon, quart and cubic inch. Volume and length (cubed) have a symbiotic relationship.
The total volume much a container is usually thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the quantity of fluid (liquid or gas) that the container may hold. The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms for the nitrogen to be liberated while also oxidising the hydrogen and carbon atoms.
Therefore, the decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.

What element is added to copper to make bronze? Why is this important for making bells?
Answer:
The correct answer is - tin.
Explanation:
Tin is the element that is mixed with copper to make bronze as bronze has many unique properties such as crisp sound quality and hardness. The hardness of the bronze allows them to make a good quality sound is come by adding tin to copper restricts the free flow of electrons of the copper atoms.
The pure metals have molecules present in an orderly manner and allow the electrons to free flow. This is why bell makers use bronze as it does not allow electrons to move freely which makes it hard and makes a good sound.

Which formula represents a
polar molecule
containing polar covalent bonds?
A. H2O
B. CO2
C. NaCL
D. Cl2
Answer:
A. H2O
Explanation:
Let us first define the three types of bonds:
1. Nonpolar Covalent: electronegativity difference < 0.4
2. Polar Covalent: electronegativity difference between 0.4 and 1.8
3. Ionic: electronegativity difference > 1.8
This will help us eliminate choices C and D:
-NaCl has a electronegativity difference of 3.0 - 0.9 = 2.1 (ionic bond)
-Cl2 has a electronegativity difference of 3.0 - 3.0 = 0 (nonpolar covalent bond)
However, we still have two more options, A and B, but they are not diatomic for us to use the electronegativity differences with.
We must now consult their geometries. Because CO2 has a linear geometry (O=C=O), the two sides will cancel each other out, resulting in a nonpolar covalent bond. At this point, by process of elimination, we can already determine the answer to be A. H2O. We can verify this by looking at the geometry of H2O, which is bent (H-O-H; imagine the O is above the H's, I cannot draw it in this response). H2O's bent geometry classifies it as polar covalent; the electrons are slightly more attracted towards the O, the more electronegative element. Side note: this makes the O slightly more negative in charge, whilst the H's are slightly more positive in charge.
P.S. I apologize for not being able to draw and demonstrate that last paragraph, but I hope you get a general idea. You can search up the "H2O geometry" and "CO2 geometry" to get a better idea! :)
H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct
What is Polar Covalent Bond ?A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.
Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.
Water (H₂O), like hydrogen Chloride (HCl), is a polar covalent molecule. When we look at a diagram of water , we can see that the two hydrogen atoms are not evenly distributed around the oxygen atom
Water (H₂O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule.Thus, This is an example of polar covalent chemical bonding.
Therefore, H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

Further explanationGiven
23.17 g Be
Required
Volume of H2
Solution

Be(s)+H2O(g)→BeO(s)+H2(g)
mol Be :
= 23.17 g : 9 g/mol
= 2.574
From the equation, mol H2 : mol Be = 1 : 1, so mol H2 = 2.574
