0.025 M will be the resulting concentration
Explanation:
To find the resulting concentration we use the following formula:
initial concentration × initial volume = final concentration × final volume
initial concentration = 0.15 M
initial volume = 2 mL
final concentration = ?
final volume = 10 + 2 = 12 mL
0.15 × 2 = final concentration × 12
final concentration = (0.15 × 2) / 12
final concentration = 0.025 M

100000N/m²
Explanation:
Given parameters:
Weight of the box = 120N
Area of the box = 12cm²
Unknown:
Pressure of the box on the floor = ?
Solution:
Pressure is the force exerted by a body per unit area:
Pressure = 
We need to convert the area into m² from cm²
10000cm² = 1m²
12cm² = 
= 0.0012m²
Pressure = 
= 100000N/m²

I think is true not sure but it might be
When you mix soap with water, you are diluting it unto less strong soap.
When you use soap and water mixed togehter to wash your hands, you are using the chemical propertiies of the soap to your advantage. The soap is made of hundreds of thousands of tiny strands that have a "water loving" end and a "oil loving" end. The oil loving ends attach to the oil on your skin, and the water loving ends stick out. This is called a micelle. Thousnds of micelles form and are ready to be rinsed away, with the oil that was on your skin inside of them. We need soap insted of just water because oil does not mix with water, and therfore cannot just be rinsed off with it.
