25:18 meaning for every 25 moles of oxygen there's 18 moles of water
High pressure occur where air sinks.
Creates dry and hot conditions
The solution is the mixture of the solute into the solvent particles. In 60 mL solution, 59.8 mL of solvent is added.
<h3>What are solute and solvent?</h3>
Solute and solvent are the components of a solution. They react and mix together to produce a homogenous mixture. The solute is a substance that is added to the solvent.
Solvents are substances that dissolve the added solute in them to make a homogenous solution.
Given,
Volume of Solute = 0.20 mL
Volume of Solution = 60 mL
The volume of solvent is calculated as:
Volume of solvent = Volume of solution - Volume of solute
= 60- 0.20
= 59.8 mL.
Therefore, 59.8 mL of solvent is present in 60 mL of solution.

Answer:
Explanation:
Two sig digits means that 5239 becomes 52 with some zeros behind it. How many?
There were 2 numbers after the 2. So two sig digits would become 5200
If the third digit from the left is a 5 or more then the answer would be
5300.
Combining oxygen gas and hydrogen gas to form liquid water is a chemical change. Pretty sure the rest are physical changes because a chemical change happens when a substance is altered completely. A physical change is when a substance keeps its components (I dunno what word to use) but just changes into a diferent shape. At least thats how my teacher explained it to me.
