Answer:

<u>Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.</u><u>In 2019, around 84% of global primary energy came from coal, oil and gas. Over the coming decades we need to rapidly reduce this share by displacing them with low-carbon energy sources.</u><u>Fossil energy has been a fundamental driver of the technological, social, economic and development progress which has followed.</u><u>In the sections above we looked at the consumption of fossil fuels collectively. But it’s important to look at the role of coal, oil and gas individually – their impacts are not equal. Coal, for example, typically produces more CO2 and local air pollution per unit of energy</u><u>.</u><u>There would be more research on the use of alternate fuels.</u><u>Moreover, fossil fuels are composed primarily of carbon and hydrogen atoms. On combustion they produce carbon dioxide, sulfur dioxide, and carbon monoxide as the main by-products.</u><u>Solar energy can only be captured during daylight hours.</u>

N2 reacts with hydrogen gas according to the following equation:
slega [8]

Answer:

Mass = 51 g

Explanation:

Given data:

Mass of nitrogen = 41.93 g

Mass of ammonia formed = ?

Solution:

Chemical equation:

N₂ + 3H₂      →       2NH₃

Number of moles of nitrogen:

Number of moles = mass/molar mass

Number of moles = 41.93 g/ 28 g/mol

Number of moles = 1.5 mol

now we will compare the moles of nitrogen and ammonia.

                N₂          :           NH₃

                  1          :           2

                1.5         :         2/1×1.5 = 3 mol

Mass of ammonia formed:

Mass = number of moles × molar mass

Mass = 3 mol × 17 g/mol

Mass = 51 g

The boiling point of liquid nitrogen is 77 kelvin. It is observed that ice forms at the opening of a container of liquid nitroge
icang [17]

Answer:

The answer is "The First choice".

Explanation:

The whole question can be found in the file attached.

The water vapor inside the air freezes thru the entrance of its nitrogen. This is because liquid nitrogen has a very low temperature and seems to be sufficiently cold to condensed and freeze the steam of water. At air pressure, it has a boiling temperature of -196°C. Freezing the skin producing freeze or cold burns can be associated with direct contact.
