<span>Aqueous solution is something where water is solvent. When the aqueous solution is saturated in both potassium chlorinate and carbon dioxide gas at 85C, the carbon dioxide bubbles out of the solution. The hydrophobic substances do not get dissolved in the water.</span>
Answer:
Species M. furo and F. catus
Explanation:
When you look at their family name, both species have -<em>lidae </em>at the end, indicating that they are more closely related.
Physical change because ther is force which is the electric current
Answer
The molarity (M) of the H3PO4 solution = 1.0 M
Explanation
Given:
Mass of H3PO4 = 49.0 grams
Volume of the solution = 500 mL = 500/1000 = 0.5 L
What to find:
The molarity (M) of the H3PO4 solution.
Step-by-step solution:
Step 1: Convert 49.0 grams H3PO4 to moles using the mole formula.
The molar mass of H3PO4 = 97.994 g/mol
So,
Step 2: Calculate the molarity of the solution using the molarity formula.
Putting mole = 0.50 mol and volume = 0.50L into the formula, we have;
The molarity (M) of the H3PO4 solution = 1.0 M
Here are three everyday situations which it would be useful to identify unknown substances:
1. When you have two clear substances with no labels yet you are not sure which substance is water and which one is not and not knowing what this unknown chemical might do.
2. A stain on your clothes
3. When you are not feeling well and your sense of taste is not functioning well.
The ways that these can be identified is first, start by the appearance, for example the state, color, texture, etc. And secondly, use your sense of smell. This sense is also helpful in identifying whether the substance is something strong or not.
