Answer:
Molarity of our solution= 0.46=0.5
Explanation:
When diluting a solution we can use the formula:
1
1
=
2
2
= M= Molarity of the solution
=V=volumes
On the left side, we'll put what we know/already have and on the right side of the formula we'll put down what we want to dilute it to.
Let's plug in what we already know.
(0.700M)(2L) = (M2)(3L)
Solve for M2 by dividing both sides by 3 so M2 will be by itself.
(0.700M)(2L)/(3L) = M2
M2= 0.46, we can round it up to 0.5
Answer:
Physical
Explanation:
Olive oil, vinegar, salt, and pepper are shaken together to make salad dressing. Physical or chemical change?
Physical
So ions are atoms that have either gained or lost electrons to complete their energy levels.
In order for a positive ion to be formed, an atom must lose electrons.
In order for a negative ion to be formed, an atom must gain electrons.
When an atom loses and electron, it loses a negative charge and then becomes a positive ion.
The answer is matter because that is the answer
