In the noble gasses section. Above neon is helium, which means it has less atomic mass, and is in the same section
Answer:
Hydrogen and Oxygen
Pureified water has been filtered or processed to remove impurities like chemicals and other contaminants, while tap water is not and it is composed of minerals that may not be seen in purified water.
Chemicals are the most common type of water contaminants. They affect both surface and underground water bodies. Industries and farming activities are the leading cause.
Alcohol: Probable human mrcinogen
Arsenic: Skin hyperpigmentalion: oxidative stress;
peripheral neuropathy; bladden skin,
liver, lung, and lymphatic cancer
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Based on their percent concentration, the 5% sugar solution contains more water.
<h3>What is the concertation of a solution?</h3>
The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.
Concentration of solutions can be expressed as either:
- molar concentration
- mass concentration
- percentage concentration
The concentration of the sugar solutions are given as percent concentration.
The 5% sugar solution contains 5% sugar and 95% water
The 10% sugar solution contains 10% sugar and 90% water.
Therefore, the 5% sugar solution contains more water.
