Answer: Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
(1)Extra greenhouse gases in our atmosphere are the main reason that Earth is getting warmer.
(2)Greenhouse gases, such as carbon dioxide (CO2) and methane, trap the Sun's heat in Earth's atmosphere.
(3)It says that the 1997 Kyoto Protocol was an unmitigated success, with every single one of the 36 countries that signed up reducing their mean annual greenhouse gas emissions from 2008-2012 by an average of 5% relative to the levels seen in 1990.Jun 15, 2016 Many argue that Kyoto's failure is due to deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme.by 2012

Answer:</h3>
3.11 moles
<h3>
Explanation:</h3>
We are given 56 g of water (H₂O)
Required to calculate the number of moles of water.
- The relationship between moles, mass and molar mass is given by;
- Moles = Mass ÷ molar mass
in this case;
- Mass of water = 56 g
- Molar mass of water = 18.02 g/mol
Therefore;
Moles of water = 56 g ÷ 18.02 g/mol
= 3.11 moles
Therefore, moles of water in 56 g will be 3.11 moles
The molarity of the ammonia solution is 1.38 M
<h3>Definition of molarity</h3>
Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>Determination of the mole of NH₃</h3>
•Mass of NH₃ = 23.5 g
•Molar mass of NH₃ = 14 + (3×1) = 17 g/mol
•Mole of NH₃ =?
Mole = mass / molar mass
Mole of NH₃ = 23.5 / 17
Mole of NH₃ = 1.38 mole
<h3>Determination of the molarity </h3>
•Mole of NH₃ = 1.38 mole
•Volume = 1 L
•Molarity of NH₃ =?
Molarity = mole / Volume
Molarity of NH₃ = 1.38 / 1
Molarity of NH₃ = 1.38 M
