if matter is made of many tiny particles, why does it seem to be continuous? Why doesn’t water seem to behave like sand?

Water and some other molecules exhibit a property know as hydrogen bonding.  A hydrogen atom in one molecule of water is attracted to the oxygen in a neighboring molecules of water.'

The force of this attraction is less than a standard chemical attractive force, but it is real and measurable.

When billions and trillions of water molecules are held together by this force, the small amount of molecule to molecule force is added up to a tremendous force.  That is why even though sulfur is below oxygen on the periodic table, hydrogen sulfide is a gas while hydrogen oxide is a liquid at room temperature.

Hydrogen bonding explains the unique properties of ice, liquid water and steam,We all know water exists in several forms such as solid, liquid and ice. Water boils at 100  C and freezes at 32  F, right? Am I correct? Let us look at some of the chemistry behind forms of water.  

The strong polar bond between water molecules creates water cohesion.

As they are cooled, aggregates of most other substances increase monotonically in density becoming progressively heavier -- the colder they are, the more tightly packed their molecules become. But water possesses a peculiar physical feature: ice expands, so it is lighter than liquid water (i. e., ice floats). When water trapped in rock crevices freezes, it breaks rocks (and pipes).

 

Water is vital to all known life forms, that is, all those on planet Earth. It is so integral to life as we know it that many biologists cannot even envision life without water (although that might be possible). Indeed, the physical properties of water dictate critical thermal limits for living systems.

In one sci-fi story, an alien refers to humans as "ugly bags of mostly water" -- our bodies are about 60-70% water, depending upon how dehydrated we are at any given time. Humans use massive amounts of freshwater to drink, cook, bathe, flush toilets, do laundry, fill swimming pools, irrigate yards and gardens, run flowing fountains, and for recreation. Precious clean water is often wasted, such as when people leave tap water running while washing their hands or brushing their teeth. The personal water consumption of an average American is about 200 gallons per day, but when industrial and energy usage is added in, per capita freshwater usage is more than 2000 gallons/day. People in third world countries use much less water, of course.

Most freshwater is claimed or "owned" and there is not enough to go around. Approximately half of the world's population of people do not even have adequate access to clean drinking water. One of the major symptoms of the human overpopulation crisis is shortages of available fresh water. Wars will be fought over water.

Answer 2

Hydrogen bonding is a property of water and some other molecules. A hydrogen atom in one water molecule is attracted to an oxygen atom in another water molecule.

What is a matter?

Matter is a substance composed of various particle types that occupies physical space and has inertia.

According to modern physics principles, each type of particle has a distinct mass and size. The electron, proton, and neutron are the most well-known examples of material particles.

Atoms and molecules are tiny particles that make up solids, liquids, and gases.

This attraction has a lower force than a standard chemical attractive force, but it is real and measurable.

When this force holds billions and trillions of water molecules together, the small amount of molecule to molecule force adds up to a tremendous force.

Thus, due to these bonds, the water does not seem to behave like sand.

calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?

Answers

Answer: 0.25 moles NH3

              1.51x10^23 molecules NH3

Explanation:

5.6dm3 (cubic decimeters)

1 dm^3 = 1 liter

We have 5.6L of ammonia (NH3 gas) at STP.  All gases at STP occupy 22.4 liters/mole.  Use this information as a conversion factor:

(22.4 L NH3)/(mole NH3)

Therefore:

(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3

Use Avogadro's number to convert moles to particles/molecules

(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3

What is the importance of water?

Answers

IMPORTANCE:

Water is very important. Whether it's from washing your dishes to hydrating, to simply just watering your flowers, water is important.

Washing Dishes

When you eat, after you eat, you wanna clean your dish. You're not gonna keep it dirty, you're going to have to wash it. Soap and water are often used when washing dishes. It's the best way to get it cleaned.

Hydration

Drinking water can have many benefits. It can make you more productive, you can even lose weight, no migraines, and it can boost your metabolism.

Watering Flowers

It's helpful to water plants because watering them on a basis/routine can help them gain nutrients. No watering the plant can result the plant drooping down and for it to become droopy and dry.

A sample of an unknown gas occupies 5.51 L at 1.31 atm. What pressure would thisgas exert in a 0.520 L container if the temperature is held constant?

Answers

Answer:

P₂ = 13.9 atm (3 sig. figs.)

Explanation:

The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...

P ∝ 1/V => P = k/V => k = P·V

For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂

Given:

P₁ = 1.31 atm.

V₁ = 5.51 L

P₂ = ?

V₂ = 0.520 L

V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)
