Answer:  Savanna, Woodland, or Grassland.

Giraffes eat new shoots and leaves, their habitat needs to have a good supply of trees -- they flock towards acacia trees in particular. Giraffes use their extremely long legs, necks and tongues to browse mainly from the thorns on the acacia tree. The tongue and the inside of the mouth are lined with tough tissue that protects against the thorns.

Volume in liters of Carbon dioxide : 0.672

Reaction(combustion of butane-C₄H₁₀)

2C₄H₁₀+13O₂⇒8CO₂+10H₂O

mol butane (MW=58,12 g/mol) :

[tex]\tt \dfrac{0.85}{58,12}=0.015[/tex]

mol CO₂ : mol C₄H₁₀ = 8 : 4, so mol CO₂ :

At STP, 1 mol = 22.4 L, so volume CO₂ :

Answer:

The number of degrees of longitude that separates New York City from Denver, Colorado is 30.9843 degrees longitude

Explanation:

The longitude of New York City is 74.0060° W

The latitude of New York City is 40.7128° N

The longitude of Denver, Colorado is 104.9903°W

The latitude of Denver Colorado is 39.7392°N

Therefore, the difference the number of degrees of longitude that separates New York City from Denver, Colorado is 104.9903 - 74.0060 = 30.9843°.

Answer:

Radiation ...........

[tex]\huge\boxed{Conduction}[/tex]

Conduction is the transfer of heat when two things come in contact with each other. The energy transfer is from hotter body to the colder body.

                                x---------------------------------------------x

There is a trick behind fire-walking. When the coal burns, after sometime there is a layer of ash on the surface of the coal which blocks the radiation. So the transfer of heat is not possible from radiation. Conduction is the only way possible. The person's feet and coal both are poor conductor of heat so if we walk quickly i.e. there is minimal time of contact with the coal, it will just feel a little warm. As the person start walking on the coal, It has to do it quickly, that way Person will feel its sole warming up but it is not that hot because of the layer of ash and poor conductance, after few steps the ash also sticks on to the sole of the person which makes kind of double layers of ash. So the only way for heat transfer is CONDUCTION.

Answer:

The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds.

Answer:

Explanation:

NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

Answer:

A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".

Answer:

Explanation:

Radioactive decay follows the equation:

Ln [A] = -kt + ln [A]₀

Where [A] is amount of isotope after time t: Our incognite,

k is rate constant: ln 2 / Half-life = 0.0231 years⁻¹

t are 60 years

[A]₀ is initial amount of isotope: 1.0g

Replacing:

Ln [A] = -kt + ln [A]₀

Ln [A] = -0.0231 years⁻¹*60 years + ln 1.0g

ln [A] = -1.386

[A] = 0.25g

Answer:

Answer:

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. Condensation is the process by which water vapor in the air is changed into liquid water.

Answer:

Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020 bahsgsh bvshgs d hg

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

Answer:

P = 34.1 L

Explanation:

Given data:

Number of moles = 10 mol

Volume occupy = 15 L

Temperature = 350°C

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

350+273 = 623 K

by putting values,

P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K

P = 511.48atm.L/15L

P = 34.1 L
