Explanation:

Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. ... The screw consists of a narrow inclined plane wrapped around a cylinder.

Answer: Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria.

Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.

Green substance in producers that traps light energy from the sun, which is then used to combine carbon dioxide and water into sugars in the process of photosynthesis Chlorophyll is vital for photosynthesis, which helps plants get energy from light.

Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

Answer:

5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

Explanation:

The balanced equation in this question is

Iron + Sulfur = Iron(II) Sulfide

Fe (II) + S --> Fe(II)S

Thus one mole of sulfur reacts with one mole of Fe(II)

Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

Answer:

srgerhe5h4hebdfbdfdfnafyn

Explanation:

Answer:

Ortho nitrophenol is more acidic than ortho-methoxyphenol.

Reason:

This is because the nitro-group is an electron-withdrawing group. In the case of ortho methoxyphenol; methoxy group is an electron-releasing group. Thus, it increases the electron density in the O−H bond and hence, the proton cannot be given out easily.

Answer:

23.4

Explanation:

23.4 g mass of sulfur yielded by this reaction.

[tex]Percentage yield = (Actual / Theoretical)\times 100[/tex]

The theoretical yield for S is as follows:-

[tex]71.0\ gCl_2\times\frac{1\ molCl_2}{71\ g Cl} \times\frac{1}{1} \ mol\times\frac{32.1\ g}{molS} =32.1\ gS[/tex]

Actual yield=[tex]32.1\ gS\times73\%=23.4\ g\ S[/tex]

Answer:

The Major features of the ocean floor are:

Explanation:

1. Continental Shelf: This refers to the part of the land on every continent that is covered with water that is not too deep. The types of animals that can be found on the continental shelf are:

Crab, Tuna, Lobster, Dungeness cod, etc. Within the Continental shelf, there are permanent rocks that house other organisms such as sponges, anemones, clams, sponges, oysters. The continental shelf also contains the route of migration for bigger animals such as sea turtles dolphins and even whales.

2. Continental Slope: This spans from the shelf break to the continental rise.  It can slope up to 4 degrees. Slopes can be created by faulting, slumping of huge boulders of sediments, rifting, etc.

Some of the aquatic animals that can be found in this region include but are not limited to:

Sablefish, Dover sole rockfish, etc.

3. Continental rise

This part of the ocean floor usually has a very steep gradient or angle slope. It slopes very steeply into the abyssal plain of the ocean.

The following can help form continental rise:

4. Abyssal Plain.

This is the real bottom of the ocean. There is a very high probability that one would find animals such as nematodes, polychaetes, etc which are all types of worms down there. The Abyssal plain is also home to molluscs,  and echinoderms.

5. Oceanic Trench

Sometimes there is a long and narrow indenture or depression along the seafloor. These are called Trenches. Trenches are sometimes formed by the boundaries between one lithospheric plate and another. The deepest trench on earth is found in the Pacific Ocean. It has been nick-named the Challenger Deep and said to be the deepest point known on earth reaching almost 11 kilometers.

6. Mid-Ocean Ridge

This is a mountain range underneath the ocean. It is formed when there is an upward push by convection currents of the mantle beneath the oceanic crust. When this happens and molten magma is ejected or created at the boundary between the plates, the result is a Mid-Oceanic Ridge.

Answer:

82.9% Is the percent yield

Explanation:

First, we need to balance the equation.

Ca(CO3) + 2HCl → H2O + CO2 + CaCl2

Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.

[tex]\frac{200g HCl}{1}[/tex] x [tex]\frac{1 mole HCl}{36.46gHCl}[/tex] x [tex]\frac{1 mol CO2}{2molHCl}[/tex] x [tex]\frac{44.01CO2}{1molCO2}[/tex] =120.707 g (theoretical yield)

Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.

Answer:

Isotopes are basically atoms of an element that have an unequal number of neutrons and protons. Of course the proton number remains the same, but the neutron number either decreases or increases, which leads to an overall change in mass. However, no chemical properties of the atom/element are changed as the electrons are the same number and do not react. In regards to Helium 4, the original number of neutrons in Helium is 2, and protons 2 as well. We see an equal number of neutrons and protons, hence an unchanged mass, and the element is not an isotope.

Answer:

Na2S + 2HCl -------------------> 2NaCl + H2S.

2NaCl --------------------------> 2Na + Cl2

Na2S + 2HCl ---------------> 2NaCl + H2S

Explanation:

Stoichiometry Is one of important aspect of Chemistry that will be taught to student learning chemistry. It shows the relationship between the reactants and the product. For instance, the amount a reactant reacts to form the products and the amount of products formed.

The balanced chemical reaction for the equation of reaction given in the question is given below;

Na2S + 2HCl -------------------> 2NaCl + H2S.

One mole of Na2S reacts with 2 Moles of HCl to produce 2 moles of NaCl and one mole of H2S.

2NaCl --------------------------> 2Na + Cl2

Two moles of NaCl breaks down into 2 moles of Sodium(solid) and one mole of Chlorine.

Na2S + 2HCl ---------------> 2NaCl + H2S

One mole of N2S reacts with 2 moles of HCl to produce 2 moles of NaCl and one mole of H2S.
