For wach of the following cases, state whether the density of the object increases, decreases, or remains the same:

Chemistry
1 answer:
Ahat [919]3 years ago

Answer:

a) increases.

b) remains the same.

c) decreases.  the hydrogen molecules constrict or shrink from actual size!

Explanation:

Since ,

Density is given as mass divided by the volume .

( a ) As the Chlorine gas is compressed , the molecules of gas comes close to each other , and hence , the density increases .

( b ) When the lead is taken to high mountain , its density remains the same , as density is independent of higher pressure , as going to mountain will increase the pressure .

( c ) As the water is freeze , its density decreases ,

Because ice is less dense than water , as seen , the ice ice can float on the surface of water .

Explanation:

(1)

True

The winds are significant in the distribution of heat across the globe. There are global air circulations around the world such as the Hadley and polar cells that take heat from the hotter regions to the cooler regions. This is driven by high and low-pressure systems on earth that are influenced by the sun. Cooler air masses move from the high-pressure system and displace the warm winds in the low-pressure systems. This helps in maintaining a heat balance on earth.  

(2)

False

The geosphere not only includes all the rocks on the surface of the earth but also the whole of the lithosphere ( or crust), which also includes all the landforms on earth. All the rocks and minerals in the interior of the earth are also part of the geosphere, including the process – such as the convection currents of the mantle- that helps in the shaping of the earth's surface.

(3)

A.

In a storm, the heat from the hydrosphere which is transferred to the atmosphere via the heat of evaporation is what feeds the storm. Therefore these two spheres not only share distribution of heat energy but also water. When the storms dissipate the heat and its water from the clouds, the water flows back to the hydrosphere and the cycle continues.

(4)

True

The biosphere includes all the living and biotic components on earth. Therefore even the marine animals in the oceans are part of the biosphere. They are one aspect that signifies the interaction betwene the hydrosphere and the biosphere. These organisms draw oxygen, water and minerals from the hydrosphere which is important or life.

(5)

True

However, the atmosphere is not the only sphere that distributes heat across the globe. So does the hydrosphere. The ocean's currents are very significant with this regard just as are air currents, The warm surface currents from the equator distribute heat towards the poles while cooler deeper currents  flow towards the equator from the poles – maintaining a heat balance on earth.

(6)

D.

When a volcano erupts, gases  -like sulfur dioxide and carbon dioxide- and pyroclasts from deep in the earth rocks (geosphere) are spewed into the atmosphere. This is an example of how these two spheres of the earth interact.

Carlos is looking at a picture of a convergent boundary on which a volcanic arc and a trench are identified. Which type of conve
Elan Coil [88]

The answer would be:

Oceanic-Oceanic Convergent Plate

This is why:

When two oceanic plates collide, the heavier of the two would subduct or in other words, go under the other plate. When this happens, ocean trenches and volcanic arcs form. The trench forms at the point oceanic plate goes under the other plate. And above the other plate that goes over create volcanic arcs.

Identify ammonia. a. strong electrolyte, strong base b. weak electrolyte, strong base c. strong electrolyte, weak base d. nonele
dedylja [7]

Answer:

Ammonia is a weak electrolyte, weak base.

Option e.

Explanation:

Ammonia can take a proton from water to make ammonium.

It is a base, because it takes proton.

When a compound can take protons, we know that is base, according to Bronsted Lowry theory.

We can't describe ammonia as a base, according to Arrhenius, but we know it is base according to Lewis, because the N from the ammonia can be a donor of its electron pair.

It is weak because an small amount of ammonia, can react to produce ammonium, between the protons of water. This is the equilibrium, where the ammonia is considered as the conjugate strong acid of ammonia.

NH₃ +  H₂O  ⇄  NH₄⁺  +  OH⁻     Kb

All the amines are considered as weak bases, because they look like ammonia, where the H of NH₃ are replaced by others chains.

------NH₂

-----NH-----
