The higher concentrated solution is 0.250 mole LiCl dissolved in 250 ml of solution
( B).0.250mole of LiCl diluted in 250ml solution
<u>Explanation:</u>
<u>Procedure to find the intensity of the solution:</u>
To find the intensity of the solution, we have to use the following formula
M1V1=M2V2
250mL of a 0.500 M aqueous solution of LiCl is diluted with water
250 ml of a 0.250M aqueous solution of LiCl is diluted with water
Thus the PH level of a solution increases from ascending order, Therefore the Solution with 62.5M is a higher concentration than that of the solution with 125M.
There is only one orbital in the s sublevel. It can hold up to two electrons.
Answer:
4.419 g
Explanation:
55 years is 5.5 half lives
200 g * (1/2)^5.5 = 4.419 g
Omitted options and they are
a) pure compound.
b. pure element.
c. pure substance.
d. homogeneous solution.
e. heterogeneous solution
Answer:d. homogeneous solution.
Explanation:
Pure substances or elements or compounds have a definite and sharp melting or boiling point, Any substance that is not pure is impure and will have different temperature of melting or boiling points.
To this effect, the clear colorless liquid cannot be a Pure substance, element or compound.
We can therefore say that the clear colorless liquid would be a homogeneous solution because a homogeneous solution is a mixture of constituents which completely mixes together such that each constituents cannot be seen with naked eye, When heated to boiling, each constituent in the mixture will give different boiling points.
A heterogeneous Solution, too is a mixture but contains constituents that can be seen and not a clear colourless solution.
Therefore On the basis of this information, we can say that the material in the beaker was a Homogeneous solution
Business owners must consider the products mission statement, a unique brand, the timing, the packaging, promotion, the audience.
To create a product you first need a problem then a solution. So if the problem is that water bottles aren’t holding enough water, the solution would be to create bigger yet lighter water bottles.
Let’s say you are to create a water bottle that is sturdier than others and can hold more water but weigh less. You would first consider the target audience. People that exercise and are into fitness would find the product more useful. So many making changes to the product to better fit their needs will help. Next the promotion and timing . It would be best to release the product near New Years since that’s when most people go to gyms. This will allow your product to reach a greater target audience and have more sales. Also testing your bottle to make sure it’s up to what you’re proving and so on.
