What is Earth's Axis and why is it important when we talk about the seasons?

Chemistry

Nady [450]3 years ago

Answer:

Explanation:

Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom." Earth spins around this pole, making one complete turn each day. That is why we have day and night, and why every part of Earth's surface gets some of each. Earth has seasons because its axis doesn't stand up straight.

Earth's axis is not perpendicular. It has an axial tilt or obliquity. Axial tilt is the angle between the planet's rotational axis and its orbital axis. A planet's orbital axis is perpendicular to the ecliptic or orbital plane, the thin disk surrounding the sun and extending to the edge of the solar system.

The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected.

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Earths axis is tilted and also depends on the tilt according to the seasons. Earths axis is an imaginary line that isn’t visible, as seasons change you see changes in climate like summers are very hot and winters are cold, it’s all related to earths axis as in one part of the world is day while the other night some parts maybe evening (depends on the time), some parts winter some summer- sorry if I made it complicated but hope this gives u an idea, the other guy deserves brainliest tho

At 25.0°C the Henry's Law constant for dinitrogen monoxide (N2O) gas in water is 0.025 M/atm.
Paladinen [302]

Answer:

The mass in grams of N₂O gas that can be dissolved is 0.18 g

Explanation:

The solubility of a gas is proportional to the partial pressure of that gas, over a determined solvent. That's what Henry's law states. We see the formula:

S = K . Pp

Where S is solubility and K is Henry's constant. This specific for each gas and each temperature, while Pp means partial pressure.

We replace data:

S = 0.025 M/atm .  0.69atm

S = 0.01725 M

This is the solubility of the gas, so now, we need to know what mass of gas is solubilized. We convert the moles, with the volume of water.

0.01725 mol/L . 0.235 L = 4.05×10⁻³ moles

Now, we determine the mass in grams:  4.05×10⁻³ mol . 28 g / 1mol =

0.1782 g

The fuel used in many disposable lighters is liquid butane, C4H10. Butane has a molecular weight of 58.1 grams in one mole. How
viktelen [127]
The exact molecular mass for butane (C4H10) is 
12.0096*4+1.0079*10=58.1174  which is 58.1 to 3 significant figures.

Proportion of carbon in the compound
12.0096*4: 58.1174
=>
48.0384 : 58.1174

The mass of carbon in 2.50 grams of butane can be obtained by proportion, namely
Mass of carbon
= 2.50 * (48.0384/58.1174)
= 2.0664
= 2.07 g (approximated to 3 significant figures)

Reaction has a theoretical yield of 56.9 g. when the reaction is carried out, 36.6 g of the product is obtained.
musickatia [10]
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield

actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)

(56,9 x100)/36,6=
= 155%
