Answer: Why don't we feel the air pressing on us all the time?
Explanation:
Because air is a fluid, the weight of the air is transmitted to the palm of your hand and to the back of your hand at the same time. These forces cancel so that your hand overall feels no net force
Answer:the gravity in the atmosphere is pulling all the air so we can survive

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 do scientists think is responsible for this dramatic change in height? Cite evidence from the text to support your answer.
Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

If 23.17 g of beryllium (Be) reacts with water at standard temperature and pressure,
how many liters of hydrogen (H2) are produced?
Volume of H2 produced = 57.6576 L
Further explanationGiven
23.17 g Be
Required
Volume of H2
Solution
Reaction
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
Volume H2(assumed at STP, 1 mol=22.4 L) :
= 2.574 x 22.4 L
= 57.6576 L

Draw a graph of how kinetic energy & temperature are related
(LOOK AT THE PICTURE ATTACHED)
Answer:
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Plz help me with these three please please !!!!!
Explanation:
Cations are positively charged ions with fewer electrons than protons. To partake in reaction, metals lose electrons to achieve a stable octet configuration. It has lost valence electrons and wold have a positive charge associated with it.
Potassium is a group 1 element. A metal.
Potassium has 1 valence electron so it loses the valence electron to form a stable octet.
A potassium ion has a positive charge and therefore cannot be an anion but is a cation.
The group number pretty much denotes the number of valence electrons.
Group 1 = 1
Group 2 = 2
Group 17 = 7
Group 18 = 8

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.
