This reaction shows that when ammonia react with oxygen it form water and nitrogen gas.
There are two reactants on left hand side oxygen and ammonia. Ammonia is formed when nitrogen and hydrogen react. While on right hand side there are two products nitrogen and water. Water is formed by the reaction of hydrogen and oxygen.
The given reaction also shows that it follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

How does an increase in the annual melt season in Antarctica have a global effect?
a.
It causes an increase in heat related illness and death.
b.
It causes the global concentration of carbon dioxide to decrease.
c.
The water in the melting glaciers can cause sea levels to rise.
d.
None of the above is true.
Please select the best answer from the choices provided
A
B
C
D
Answers
Answer:
The correct answer is option "C"
The water in the melting glaciers can cause sea levels to rise.
The increase in annual melt season indicates a prolonged melting (hot) season which is primarily due to the impact of global warming. Global warming is increasing the highest temperature mark in the hot seasons on the planet which is adversely affecting the polar regions of earth. The ice in these Polar Regions has started melting. This ice when converted into liquid form flows through regions to reach sea and oceans and thus causes the rising of sea level
The annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.
What is the annual melt season?The annual melt season refers to a period of time when the ice in cold and polar regions of the world begin to melt to form warm.
The melting of ice in these regions such as Antarctica results in a rise in the global sea levels.
Therefore, the annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.

You are an employee at "cash for gold" and a customer comes in looking to exchange gold for money. They claim to have 3.47 gram nugget of fold. How many particles (atoms) of gold are in one nugget? With work shown
Answers
Answer:
The number of atoms in 3.47 gram nugget of gold is approximately 1.0606 × 10²² atoms
Explanation:
The given mass of gold = 3.47 grams
The molar mass of gold = 196.96657 g/mol
The number of moles of gold in 3.47 grams of gold = 3.47 grams/(196.96657 g/mol)
The number of moles of gold in 3.47 gram nugget of gold = 0.01762 moles
The number of atoms in one mole of gold = 6.02 × 10²³ atoms
The number of atoms in 0.01762 moles of gold = 6.02 × 10²³ atoms/mole × 0.01762 moles
The number of atoms in 0.01762 moles of gold ≈ 1.0606 × 10²² atoms
∴ The number of atoms in 3.47 gram nugget of gold ≈ 1.0606 × 10²² atoms.
