What does this rising heat and resulting convection cycle do to our rigid lithosphere

Answer:

there is no 2d so the first one is no good

the other 2 look good

Explanation:

Answer:

Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell. Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.

Answer:

There are more hours of daylight at Location X than at Location Y.

Explanation:

The student has created a model in the diagram in which sun and earth are presented. There are two point location on earth one is x and other is y. The x point is declined towards the sun which means that locations on point x receives more light than location Y. There will be more hours of daylight at Location x.

The best comparison of the conditions at Location X and Location Y is there are more hours of daylight at Location X than at Location Y.

The sun is the big spherical of heat and energy. The sun gives light. The Earth is the third planet of our solar system.

Thus, the correct option is C, There are more hours of daylight at Location X than at Location Y.

um that looks like a molecular bond, but in energy bond, that would be a solid form i guess, it looks like two of the same atoms are fused together to create a molecular bond.

Explanation:

Answer: bond pair of O-O bond to a greater extent than the lone pair of electrons on the sulfur atoms in S-S bond....as a result S-S bond (bond energy=213 kj/mole)is much more stronger than O-O(bond energy = 138 kj/mole) bond …

Answer:

All of the consumers and producers eventually become nourishment for the decomposers.

Explanation:

Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Answer:

Area = 51.74cm ² 

Explanation:

5.6 × 9.4 = 51.744

Round above answer

= 51.74

Answer:

Explanation:

first, you calculate the amount of O2 in moles:

98.0 ÷ 32 = 3.0625

second, the ratio if O2/C3H8 is 5 so you need to calculate O2 in moles with that:

3.0625 ÷ 5 = 0.6125

third, the amount of CO2 in moles also can be calculate by the ratio of C3H8/CO2 which is 3

0.6125 × 3 = 1.8375

then multiply CO2 in moles by its molar mass which is 44 g/mol

1.8375 × 44 = 80.85g

Answer:

1.25 moles of tungsten carbide

Explanation:

Tungsten carbide, WC, is a substance that is produced prom carbon and tungsten as follows:

W + C → WC

Based on the reaction, 1 mole of Carbon produce 1 mole of tungsten carbide. That means if 1.25 moles of carbon are added in excess of tungsten, the moles of tungsten carbide produced are:

Answer:

1) The temperature inside a diesel engine is high enough for two atmospheric gases nitrogen and oxygen to react and combine to form nitrogen oxides, NOₓ

At very high temperatures of above 1,300 °C, which are temperatures obtainable in the internal combusting chamber of a diesel engine under 100% load, air containing N₂ and O₂ is sucked in, and they combine to produce approximately 85% of the NOₓ pollutants produced from moving engine sources

2) a) N₂O contributes to the Greenhouse effect and therefore global warming

b) NO₂ contributes to the formation of smog and NO₂ combines with water to produce nitric acid which falls as acid rain, and causes irritation in the eyes and the respiratory system airways

c) Nitric oxide gas, NO, has the effect of depleting the Ozone layer which increases global warming and increased penetration of UVB

1. An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. Groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.

2. watershed

Simply put, a watershed is “all the land area where the rain runs downhill to a certain point,” explains Carolyn Staudt, who leads NSF-funded science projects at the Concord Consortium on land use and its effects on water resources.

3. Healthy watersheds provide critical services, such as clean drinking water, productive fisheries, and outdoor recreation, that support our economies, environment and quality of life

What is an aquifer : natural underground storage area

What is the name for the land area where all rain runs downhill to a certain point : collection? normally would be called watershed.

Why are watersheds important for the maintenance of water quality : 1, 2

Answer:

5.167 kJ

Explanation:

We have to divide the heating process into two steps: one for the heating process of liquid water (1) and the other for the phase transition from liquid water to steam at 100°C (2)

1 - heating from 52.1°C to 100°C:

heat(1) = m x Cp x ΔT = 2.1 g x 4.184 J/g°C x (100°C-52.1°C) = 420.9 J

2 - vaporization at 100°C:

heat(2) = m x ΔHv = 2.1 g x 2260 J/g = 4746 J

Finally, we add the heat values of the steps:

heat required = heat(1) + heat(2) = 420.9 J + 4746 J = 5166.9 J

Since 1 kJ= 1000 J, we convert from J to kJ:

5166.9 J x 1 kJ/1000 J = 5.1669 kJ ≅ 5.167 kJ

Answer:

The force of the atmosphere 200 KN.

Explanation:

Pressure is the ratio of force applied to the area  to which the force is applied.

i.e Pressure = [tex]\frac{Force}{Area}[/tex]

But, Pressure = 100000 pa (100000 N/ [tex]m^{2}[/tex]), and surface area = 2.0 [tex]m^{2}[/tex]

Thus,

100000 = [tex]\frac{Force}{2.0}[/tex]

⇒ Force = 100000 x 2.0

              = 200000

Force = 200 KN

The force of the atmosphere 200 KN.

Answer: Mg is a cation and Cl is an anion

Explanation: In more detail, if you look at the periodic table, the group number (or columns) of the elements, describe how many valence electrons, or how many electrons the element has available to have a complete an electron shell. Magnesium being in group 2, it has one 2 electrons that will be "donated" to an anion that it bonds with. However, Chlorine being in group 17, (look at the single digit number for double digit groups), it has 7 valence electrons. Knowing that a full electron shell is usually 8 electrons, it needs only one. Since Magnesium has 2 valence electrons to give away, two atoms of Chlorine gas will then bind to the Magnesium, where the 2 Chlorine atoms will take the electrons to fill their shells. Magnesium Chloride, in terms of charges when in ions, [Mg]2+ and 2 [Cl]-1

Magnesium chloride is formed when magnesium ion formed from the loss of two electrons and two chloride ions formed by accepting one electron each are held together by electrostatic attractive forces.

Magnesium chloride is an ionic compound which consists of magnesium ions and chloride ions.

Let's break down the equation PV=nRT.

P=Pressure

V= Volume

n= number of mole

R= the universal constant

T= Temperature

The = sign is the barrier between them. Whenever one side of the equation increases, something on the other side is directly impacted. When Temperature increases, so will pressure--and vise versa.
