write short note on earth sheltering ​

Answers

Answer:

hfxyktxykt

Explanation:

An earth shelter is a structure (usually a house) with earth (soil) against the walls, on the roof, or that is entirely buried underground.

An earth sheltered house in Switzerland (Peter Vetsch)

Earth acts as thermal mass, making it easier to maintain a steady indoor air temperature and therefore reduces energy costs for heating or cooling.

Earth sheltering became relatively popular after the mid 1970s, especially among environmentalists. However, the practice has been around for nearly as long as humans have been constructing their own shelters.

Which of these does not cause seasonal change?
A.the tilt of the Earth’s axis
B.the Earth’s orbit around the sun
C.the Earth’s distance from the sun
D.which side of the Earth is tilted toward the sun

Answers

Answer:

C.the Earth’s distance from the sun

Explanation:

Distance Does Not Cause Seasons

It is a common misconception that seasons occur because of Earth's elliptical orbit around the Sun, with winter occurring when Earth is farthest away from the Sun, and summer when it is closest to it. However, our planet's distance from the Sun has little effect on the onset of seasons.

The distance of the earth from the sun does not cause seasonal change. Therefore, option (C) is correct.

What is the reason for the seasonal changes?

The seasons are changing depending on the sunlight reaching the Earth as it orbits around the sun during the year. The season changes are caused by the Earth as it is tilted on its axis. The earth travels each year in a loop around the sun.

The hemisphere of the Earth has tilted towards or away from the Sun. Because of that, there are different types of seasons are formed which are experienced in a whole year.

Summer season occurs on the earth when the hemisphere is tilted towards the sun and winter occurs in the hemisphere tilted away from the sun.

Because sunrays travel directly to the surface of Earth, the hemisphere which is tilted toward the sun is warmer. So they are less scattered in the atmosphere.

What type of elements can react with metals to form salts

Answers

Answer:

The Alkali metals

Explanation:

The alkali metals react with the nonmetals in Group VIIA (F2, Cl2, Br2, I2, and At2) to form ionic compounds or salts. Example: Chlorine reacts with sodium metal to produce sodium chloride, table salt. Because they form salts with so many metals, the elements in Group VIIA are known as the halogens.

Alkali metals are the type of metal that can react with metals to form salts. They form ionic compounds or salts when reacting with non-metals.

What are alkali metals?

Alkali metals are the six elements of group 1 of the periodic table. thee metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

The main characteristics of alkali metals are:

They are brittle, metallic bonding causes them to be soft metals.Both their melting and boiling points are low.They are metals that are quite reactive.Ionization energy is the force needed to eject an electron from the outermost shell.

Alkali metals interact to generate ionic compounds or salts. As an illustration, sodium metal and chlorine react to form sodium chloride or table salt.

Thus, alkali metals form salt when reacting with metals.

Calculate the mass of 4.55x1024 molecules of sucrose

Answers

Answer:

2584 g

Explanation:

The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.

First we convert molecules into moles by using Avogadro's number:

4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 mol

Now we convert moles of sucrose into grams, using its molar mass:

7.55 mol * 342.3 g/mol = 2584 g

The CO2 that builds up in the air of a submerged submarine can be removed by reacting it with sodium peroxide. 2 Na2O2 (s) + 2 CO2 (g) → 2 Na2CO3 (s) + O2 (g)
If a sailor exhales 150.0 mL of CO2 per minute at 20oC and 1.02 atm, how much sodium peroxide is needed per sailor in a 24 hr period?​

Answers

Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.02 atm

V = Volume of gas = 150.0 ml = 0.15 L

n = number of moles  of carbon dioxide = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]20^0C=(20+273)K=293K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1.02atm\times 0.15L}{0.0821 L atm/K mol\times 293K}=0.006moles[/tex]

[tex]2Na_2O_2(s)+2CO_2(g)\rightarrow 2Na_2CO_3(s)+O_2(g)[/tex]

According to stoichiometry:

2 moles of carbon dioxide require = 2 moles of sodium peroxide

Thus 0.006 moles carbon dioxide require= [tex]\frac{2}{2}\times 0.006=0.006[/tex] moles of  sodium peroxide

Mass of  sodium peroxide needed for 24 hour=[tex]moles\times {\text {Molar mass}}=0.006mol\times 78g/mol\times 24\times 60=674g[/tex]

Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.

The amount (in grams) of sodium peroxide needed per sailor in a 24 hr period is 673.92 g

Determination of the mole of CO₂Volume (V) = 150 mL = 150 / 1000 = 0.15 L Temperature (T) = 20 °C = 20 + 273 = 293 KPressure (P) = 1.02 atmGas constant (R) = 0.0821 atm.L/Kmol Mole of CO₂ (n) =?

Using the ideal gas equation, we can obtain the mole of CO₂ as follow:

n = PV / RT

n = (1.02 × 0.15) / (0.0821 × 293)

n = 0.006 mole

How to determine the mole of Na₂O₂ required

2Na₂O₂ + 2CO₂ → 2Na₂CO₃ + O₂

From the balanced equation above,

2 moles of CO₂ required 2 moles of Na₂O₂.

Therefore,

0.006 mole of CO₂ will also require 0.006 mole of Na₂O₂.

How to determine the mass of Na₂O₂ required Mole of Na₂O₂ = 0.006 mole Molar mass of Na₂O₂ = (23×2) + (16×2) = 78 g/mol Mass of Na₂O₂ =?

Mass = mole × molar mass

Mass of Na₂O₂ = 0.006 × 78

Mass of Na₂O₂ = 0.468 g per minute

Mass of Na₂O₂ required for 24 h = 0.468 × 24 × 60 = 673.92 g

Since protons (p+) with a positive charge and neutrons (n0) without a charge are located in the nucleus, what is the overall charge of the nucleus portion of an atom: positive, negative, or no charge at all? Explain.

Answers

Answer:

Positive

Explanation:

The nucleus of an atom has a net positive charge  which is balanced by the negative charge of the electrons residing in the orbital of an atom. The reason why the nucleus of an atom is positively charged is because it contains two sub atomic particles;

The protons and neutrons. In terms of charge, the proton is positively charged and the neutron is neutral. This means the neutron does not partake in the charge of the nucleus. Hence the net charge of the nucleus is decided by the protons which are positively charged

if surface tension relies on intermolecular forces, how could you make surface tension decrease?
(think about how and where molecules bind to each other)

Answers

Answer:

We could make the surface tension to decrease by removing and causing a disruption to the intermolecular forces(hydrogen bonds).

Explanation:

To explain this answer, we will consider an experiment whereby a paper clip is made to rest at the top surface of water inside a container/beaker.

First of all, the intermolecular forces present in water are also known as hydrogen bonds.

It's relationship with surface tension is that when there is high surface tension in the water, this high tension will allow the paper clip to rest on top of the hydrogen bonds present at the top surface in between the water molecules.

However, the surface tension will decrease when we remove or cause a disruption to the intermolecular forces (hydrogen bonds).

why are cells small?​

Answers

Answer:

you know what i really dont know but imagine if they were huge

Explanation:

Because if a cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
They are also small so they can maximize the ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions move across the cell membrane per unit of cytoplasmic volume.

basically cells are small because they need to be able to get the nutrients in and waste out quickly.
