Why are summer days longer than winter days on Earth?
A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.
B. During the summer, Earth is at the point in its orbit when it is closest to the Sun.
C. The region of Earth experiencing summer rotates past the Sun more slowly than the region experiencing winter.
D. The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.
PLEASE HELP ITS A TEST

Answers

Answer:

A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.

Explanation:

Actually, though, the Earth is tilted 23.4 degrees! (A circle is 360 degrees.) This tilt is the reason that days are longer in the summer and shorter in the winter. The hemisphere that's tilted closest to the Sun has the longest, brightest days because it gets more direct light from the Sun's rays.

Plz mark me brainliest if correct :)

During summer days, north pole of earth is exposed to sun because ofthe tilt of earth's rotational axis. Thus, The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.

What is summer?

Summer is a season in earth. There are different seasons in earth namely, summer, winter, spring, autumn etc. These season are arising due the revolution of earth around sun.

The distance of different regions of earth from sun changes due to the revolution of earth. Thus heat gained by these regions will be different in different seasons.

The north pole in summer gains more heat and light energy because of tilt in the axis of earth is towards the sun. Hence, the day time will be longer in summer than the winter. In winter, the earth is relatively apart from sun and thus  tilt is and gains less light and heat  .

How many total ions are in 2.95 g of magnesium sulfite?

Answers

Answer:

Approximately [tex]5.65 \times 10^{-2}\; \rm mol[/tex], which is approximately [tex]3.41 \times 10^{22}[/tex] particles.

Explanation:

Formula of magnesium sulfite: [tex]\rm MgSO_3[/tex].

Look up the relative atomic mass of [tex]\rm Mg[/tex]. [tex]\rm S[/tex], and [tex]\rm O[/tex] on a modern periodic table:

[tex]\rm Mg[/tex]: [tex]24.305[/tex].[tex]\rm S[/tex]: [tex]32.06[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].

The ionic compound [tex]\rm MgSO_3[/tex] consist of magnesium ions [tex]\rm {Mg}^{2+}[/tex] and sulfite ions [tex]\rm {SO_3}^{2-}[/tex].

Notice that [tex]\rm {Mg}^{2+}\![/tex] and [tex]\rm {SO_3}^{2-}\![/tex] combine at a one-to-one ratio to form the neural compound [tex]\rm MgSO_3[/tex]. Therefore, each [tex]\rm MgSO_3\![/tex] formula unit would include one [tex]\rm {Mg}^{2+}[/tex] ion and one [tex]\rm {SO_3}^{2-}[/tex] ion (that would be two ions in total).

Calculate the formula mass of one such formula unit:

[tex]\begin{aligned}&\; M(\mathrm{MgSO_3}) \\ = & \; 24.305 + 32.06 + 3 \times 15.999 \\ = & \; 104.362\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

In other words, the mass of one mole of [tex]\rm MgSO_3[/tex] formula units (which includes one mole of [tex]\rm {Mg}^{2+}[/tex] ions and one mole of [tex]\rm {SO_3}^{2-}[/tex] ions) would be [tex]104.362\; \rm g[/tex].

Calculate the number of moles of such formula units in that [tex]2.95\; \rm g[/tex] of [tex]\rm MgSO_3[/tex]:

[tex]\begin{aligned}n&= \frac{m}{M}\\ &=\frac{2.95\; \rm g}{104.362\; \rm g \cdot mol^{-1}} \approx 2.82670 \times 10^{-2}\; \rm mol\end{aligned}[/tex].

There are two moles of ions in each mole of [tex]\rm MgSO_3[/tex] formula units. Therefore, that [tex]2.82670 \times 10^{-2}\; \rm mol[/tex] of [tex]\rm MgSO_3\![/tex] formula units would include approximately [tex]2 \times 2.82670 \times 10^{-2}\; \rm mol \approx 5.65\times 10^{-2}\; \rm mol[/tex] of ions.

Explanation:

Automobile catalytic converters use a platinum catalyst to reduce air pollution by changing emissions such as carbon monoxide, CO(g), into carbon dioxide, CO2(g). The uncatalyzed reaction is represented by the balanced equation below.2CO(g) O2(g) 2CO2(g) +heat. determine the mass of O2(g) required to completely react with 784g moles of CO(g) during this reaction.

Answers

Answer: 448 g of [tex]O_2[/tex] will be required to completely react with 784g moles of CO(g) during this reaction.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} CO=\frac{784g}{28g/mol}=28moles[/tex]

The balanced chemical equation is:

[tex]2CO(g)+O_2(g)\rightarrow 2CO_2(g)[/tex]  

According to stoichiometry :

2 moles of [tex]CO[/tex] require  = 1 mole of [tex]O_2[/tex]

Thus 28 moles of [tex]CO[/tex] will require=[tex]\frac{1}{2}\times 28=14moles[/tex]  of [tex]O_2[/tex]

Mass of [tex]O_2=moles\times {\text {Molar mass}}=14moles\times 32g/mol=448g[/tex]

Thus 448g of [tex]O_2[/tex] will be required to completely react with 784g moles of CO(g) during this reaction.

Explain the process of ionic bond formation between K
(potassium, a metal) and Br (bromine, a nonmetal).
I

Answers

Answer:

Metals transfers electrons to nonmetals. So K transfers one electron to Br because K is located at 1A in the periodic table. Br has seven electrons, now both K and Br are stable by gaining and losing one electron. The transfer of electrons makes metals to become positive ions and nonmetal to become negative ions. When an ionic bond is formed, the charges attract each other.

Answer: Metals transfers electrons to nonmetals. Potassium -K transfers one electron to bromine- Br because K is located in group 1A on periodic table. Br has seven electrons and located group 7A. Both K and Br stable by gaining and losing one electron. The transfer of electrons makes metals to become + positive ions and nonmetal to become - negative ions. An ionic bond is formed, the charges attract each other.

Explanation: Metals donate, or transfer, electrons to the nonmetal.

The transfer of electrons creates a positive ion and a negative ion.

An ionic bond is formed when the charges attract each other.

If the gas tap to the Bunsen burner is turned on, the methane does not start burning until it is lit with a match. Why is heat from the match needed to start the methane burning?

Answers

Answer:

The reaction has a high activation energy

Explanation:

The burning of methane is a spontaneous reaction. Once the burning begins, the flame is able to sustain itself without any additional input of energy. It is an exothermic reaction in which energy is given out in the form of heat.

The reason why heat from the match is needed to start the burning of methane is that the activation energy of the combustion of methane is high. Activation energy is the energy that must be supplied in order for the collision of reactants to result in chemical reaction.

As long as the activation energy is high, the reaction can not occur without an external input of energy (e.g striking a match). Hence the answer.

Photosynthesis requires light, water, and CO2 to work. When one of these factors is in short supply, it is called a limiting factor. Temperature can also be a limiting factor when it is too hot or too cold for photosynthesis to work well. If you are trying to grow plants in a greenhouse, why is it important to know the limiting factor?

Answers

A farmer can be more successful in understanding which plant produces and how to grow plants with a higher degree of photosynthesis with less material and time exhaustion, by recognizing what the limiting factor is.

Read the reaction and the statement.

2X(g) + Y2(g) ⇌ 2XY(s)

The equilibrium constant for the chemical reaction is found to be 20 at 150 K.

If the concentration of X is 4.0 × 10-2 M, what is the concentration of the Y2 gas?

5.50 M

8.0 M

31.25 M

40.0 M

Answers

Answer:

[Y₂] = 31.25M

Explanation:

Based on the chemical reaction:

2X(g) + Y2(g) ⇌ 2XY(s)

We must define the equilibrium constant, K as:

K = 20 = 1 / [X]²[Y₂]

Where [X] and [Y₂] are the equilibrium concentrations of each gas.

If [X] = 4.0x10⁻²M:

20 = 1 / [4.0x10⁻²M]²[Y₂]

0.032 = 1 / [Y₂]

[Y₂] = 31.25M
