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  .

State the law of multiple proportions.

Answers

Statement that when two elements combine with each other to from more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

Answer:

Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers. For example, let us assume 2 molecules CO (carbon monoxide) and CO2(carbon dioxide).

Analyze. This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys the laws of Conservation or energy

Answers

Answer:

See explanation

Explanation:

If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.

Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.

Answer:

The reaction is exothermic.

Given the following two quantities: 0.50 mol of CH4 and 1.0 mol of HCl,
a. Which has more atoms?
b. Which has more molecules?
c. Which has the greater mass?
d. Which has the greater volume at the same temperature and pressure (both are gases)?

Answers

Answer:

(a) HCl

(b) HCl

(c) HCl

(d) HCl

Explanation:

Given: 0.50 mol of CH₄ and 1.0 mol of HCl

Using stoichiometry we can calculate the answers to parts a, b, c, and d.

Part (a)

# of moles × Avogadro's number = # of atoms or molecules

Avogadro's number: 6.02 * 10²³

[tex]\displaystyle 0.50\ \text{mol CH}_4 \cdot \frac{6.02\cdot 10^2^3 \ \text{atoms CH}_4}{1 \ \text{mol CH}_4} = 3.01 \cdot 10^2^3 \ \text{atoms CH}_4[/tex] [tex]\displaystyle 1.0\ \text{mol HCl} \cdot \frac{6.02\cdot 10^2^3 \ \text{atoms HCl}}{1 \ \text{mol HCl}} = 6.02 \cdot 10^2^3 \ \text{atoms HCl}[/tex]

HCl has more atoms than CH₄.

Part (b)

This is calculated the same way as Part (a); HCl has more molecules than CH₄.

Part (c)

Molar mass of CH₄ = 16.04 g/mol

Molar mass of HCl = 36.458 g/mol

[tex]\displaystyle 0.50\ \text{mol CH}_4 \cdot \frac{16.04 \ \text{g CH}_4}{1 \ \text{mol CH}_4} = 8.02 \ \text{g CH}_4[/tex] [tex]\displaystyle 1.0\ \text{mol HCl} \cdot \frac{36.458 \ \text{g HCl}}{1 \ \text{mol HCl}} = 36.458 \ \text{g HCl}[/tex]

HCl has a greater mass than CH₄.

Part (d)

Assuming STP:

Molar volume of any gas at STP is 22.4 L/mol.

[tex]\displaystyle 0.50\ \text{mol CH}_4 \cdot \frac{22.4 \ \text{L CH}_4}{1 \ \text{mol CH}_4} = 11.2 \ \text{L CH}_4[/tex] [tex]\displaystyle 1.0\ \text{mol HCl} \cdot \frac{22.4 \ \text{L HCl}}{1 \ \text{mol HCl}} = 22.4 \ \text{L HCl}[/tex]

HCl has a greater volume than CH₄.
