Answer: The new concentration of the solution is 0.143 M.
Explanation:
Given: 
= 300.0 mL, 
= 0.335 M
= 700.0 mL, 
= ?
Formula used is as follows.
Substitute values into the above formula as follows.
Thus, we can conclude that the new concentration of the solution is 0.143 M.
In chemistry the need for standards when measuring quantities are in place for accurate measurement that is recognized world wide. This way, no matter what language people use, they will always understand there standards.
Through the erosion and indentations. Formation down cutting it leaves forms of a river or ocean carved. Using range you can see how the floor of the canyon were an ocean floor. Erosion is caused by water the Grand Canyon sits on a body of water unlike most canyons this one happened to erode and sediment the body where the water once was. A layer of rock is also apparent which you wouldn’t be able to see unless erosion happened and etc.
While staying in the same period, if we move from left to right across the period, the atomic radius decreases. The reason is, in a period the number of shells remain the same and the number of electrons and protons increase as we move across the period to the right. The increased electrons and protons attract each other with greater force and hence the atomic size decreases.
So the element on the left most will have the largest atomic radius. So the correct ans is Potassium. Potassium will have the largest atomic size among Potassium, Calcium and Scandium.
Answer: 
: Pure substance, Element
: Pure substance , Element
: Pure substance, Compound
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: 
and
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example:
Heterogeneous Mixture : Mixture that has its different components mixed unevenly within the substance
. Example: Air
Homogeneous Mixture : Mixture that has its different components mixed evenly within the substance. Example: sugar dissolved in water
