Hydrogen molecule is a molecule that releases the most energy when forming its bonds as compared to other molecules.

We know that H-H bond energy is 432 kJ mol-1, CI - CI bond energy is 239kJ mol-1 and Br-Br bond energy is 193 kJ mol-1 so from this data we can conclude that more energy is required to break the bond between hydrogen atom.

Answer:

Carbon can be found in the ocean, rocks, and the atmosphere around us.

Explanation:

64 grams of O_2O2 will be required to react completely with 4 moles of Mg.

As per the balanced chemical equation 2 moles or 48 g of Mg reacts with one mole or 32 g of oxygen. Hence, 4 moles of Mg requires 2 moles or 64 grams of oxygen gas.

Magnesium oxide (MgO) is a white solid mineral that occurs naturally as the mineral periclase. It is one of the most common and important magnesium compounds, and is widely used in many industrial and commercial applications.

The balanced chemical equation of the reaction between Mg and oxygen is given as follows:

2 Mg + O₂ ⇒ 2 MgO

As per the balanced chemical equation 2 moles or 48 g of Mg reacts with one mole or 32 g of oxygen. Hence, 4 moles of Mg requires 2 moles or 64 grams of oxygen gas.

Answer:

T2 = 242.06

Explanation:

Follow this equation to find T2: V1/T1 = V2/T2

V1 = 9.3L

T1 = 27C (to convert to Kelvin + 273.15) ---> 27 + 273.15 = 300.15K

V2 = 7.5L

T2 = ?

V2×T1/V1 = T2

7.5×300.15/9.3 = T2

242.06 = T2

So 242.06 is the answer!

Answer:

The answer is 16.12 L  

Explanation:

V2 = 50/3.1

V2= 16.12 L

The new volume can be calculated using Boyle's law. If the pressure increases from 2.5 atm to 3.1 atm, then volume decreases from 20 L to 16.1 L.

Boyle's law is a fundamental law of physics that describes the relationship between the pressure and volume of a gas at a constant temperature. It is named after the Irish physicist Robert Boyle, who first stated the law in the mid-17th century.

Boyle's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that as the volume of a gas decreases, its pressure increases proportionally.

Hence,

P1V1 = P1V2.

given,

P1 = 2.5 atm

V1 = 20 L

P2 = 3.1 atm

then V2 = P 1 V1 /P2

V2 = 2.5 atm × 20L/3.1 atm = 16.1 L.

Therefore, the new volume of the gas is 16.1 L.

Answer:

what are the roles of minerals in maintaning homeostasis?

Since oxygen is the limiting factor of the reaction, 7.14 g of hydrogen is required to react with 40 litres of oxygen.

The limiting factor in a reaction is that factor which the reaction depends on in order to proceed.

Once the limiting factor in a reaction is absent, the reaction will stop.

In the reaction between hydrogen and oxygen, twice the volume of hydrogen is required to react with oxygen.

In the given reaction, oxygen is the limiting factor.

Volume of oxygen = 40 litres

Volume of hydrogen required = 40 × 2 = 80 litres

Mass of 22.4 L of hydrogen = 2.0 g

Mass of 80 Litres = 80/22.4 × 2.0 g

Mass of hydrogen = 7.14 g

Therefore, 7.14 g of hydrogen is required to react with 40 litres of oxygen.

In image 1, the moon is in a certain spot in its tilted elliptical orbit, so it is effectively under the Earth from the Sun's perspective. But in image 2, The moon is actually behind the Earth from the Sun's perspective.

Explanation:

I kinda' explained in my answer

In image 2, the lunar eclipse because the earth's shadow falls on the surface of the moon when Earth, moon, and sun all are aligned in a straight line.

A lunar eclipse usually takes place when the Moon moves into the shadow of the earth. This eclipse happens only when the Sun, Earth, and Moon are exactly aligned with Earth between the other two, which can occur only on the night of a full moon when the Moon is close to the lunar node.

When the moon is eclipsed by the Earth, it gets on a reddish color that is caused by the planet when it fully blocks direct sunlight from reaching the Moon's surface, as only the light reflected from the lunar surface has been refracted by the atmosphere of the earth. Due to the Rayleigh scattering of blue light, this light appears reddish.

A total lunar eclipse lasts up to nearly 2 hours, lunar eclipses are safe to view. Therefore, image 2 represents the lunar eclipse.
