Which structure is the sun located

Answer:

false

Explanation:

Waves are created because othe the lunar pull with out the moon we wouldnt have waves

Answer:

A and c

Explanation:

In A the product is added to the reactant, so the real reaction is (2H2O = 2H2+O2).

In B hydrogen and clorine are combined to give hydrochloric acid and 2 is used to balance the reaction in the product, so it's a combination reaction .

In C the case is similar to A , so the real reaction is (Fe+MgO = Mg + FeO ) this is displacement reaction where a more reactive element takes place of a less reactive element .

In D sodium reacting with Chlorine to give sodium chloride ,so we conclude that it's a combination reaction .

In an ecosystem, deep, cold water is the  densest while warm, shallow water is the  least dense.

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

4 of each protons and electrons

Explanation:

since the atomic number is 4 it would contain both the same number of protons and electrons

Answer:

0.48 moles of H₂ are produced.

Explanation:

Given data:

Number of moles of H₂ produced = ?

Mass of H₂SO₄ = 47 g

Solution:

Chemical equation:

2Al + 3H₂SO₄    →    Al₂(SO₄)₃ + 3H₂

Number of moles of H₂SO₄ :

Number of moles = mass/molar mass

Number of moles = 47 g/ 98 g/mol

Number of moles = 0.48 mol

Now we will compare the moles of H₂SO₄ and  H₂

                       H₂SO₄      :        H₂

                           3           :          3

                         0.48       :        0.48

Thus, 0.48 moles of H₂ are produced.

Answer:

3

Explanation:

The atomic mass is equal to the number of protons in an atom (and electrons if the atom is neutral).

Answer:

Explanation:

Answer:

1.13moles

Explanation:

Given parameters:

Number of atoms  = 6.777 x 10²³ atoms

Unknown:

Number of moles  = ?

Solution:

A mole of a substance contains the avogadro's number of particles

       6.02  x  10²³ particles   = 1 mole

      6.777 x 10²³ atoms will contain [tex]\frac{ 6.777 x 10^{23} }{6.02 x 10^{23} }[/tex]   = 1.13moles

Answer:

Answer: Fish

Explanation:

Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

Answer:

Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.

The vapor pressure (in torr) of a 35°C solution : 52 torr

Given

x propanol = 0.75

P°ethanol=100 torr

P°propanol=36 torr

Required

the vapor pressure

Solution

Raoult's Law

P solution = xA.P°A +xB.P°B

x ethanol = 1- 0.75 = 0.25

Input the value :

P solution = 0.25 x 100 + 0.75 x 36

P solution = 25 + 27

P solution = 52 torr

Answer:

Transverse wave

Explanation:

A wave is defined as a disturbance along a medium which transfers energy from one point to another.

A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.

In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.
