Answer:
<h2>225 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.9 × 250
We have the final answer as
<h3>225 g</h3>
Hope this helps you
The answer would be moving bc for friction to happen the fault lines have to be moving
A polar bonds share electrons meaning they are a convenient bond
Answer:
The attraction of the soil to the inside of the surfactant micelle helps loosen the soil from its surface. Once the soil lifts off the surface, it becomes suspended in the water in the micelle. This suspension is also known as emulsification of one liquid into another.
Answer:
Na₂O will also form a brittle ionic compound.
Explanation:
Sodium is located in the same group as Potassium: Alkali Metals. This is because both elements have similar chemical properties. In term of their electronegativity, both elements are very close. Na has an electronegativity of 0.93, while K has an electronegativity of 0.82. This makes both ideal elements to create ionic compounds with Oxygen.
