Answer:
colloid
Explanation:
Answer:
it has 3 valence electrons
Explanation:
2+2+1 is 5, boron is 5 and its in the 3rd group
You would need to mix 0.100 liters (or 100 mL) of the 15M NaNO3 solution with enough solvent (e.g., water) to bring the total volume to 250 mL in order to obtain a 6.0M NaNO3 solution.
To prepare 250 mL of a 6.0M NaNO3 solution from a 15M NaNO3 solution, you can use the dilution formula:
C1V1 = C2V2
Where:
C1 = concentration of the stock solution
V1 = volume of the stock solution to be used
C2 = desired final concentration
V2 = final volume of the diluted solution
In this case:
C1 (concentration of the 15M NaNO3 solution) = 15M
C2 (desired final concentration) = 6.0M
V2 (final volume of the diluted solution) = 250 mL (0.250 L)
Now, plug in the values and solve for V1 (volume of the stock solution to be used):
15M * V1 = 6.0M * 0.250 L
V1 = (6.0M * 0.250 L) / 15M
V1 = 0.100 L
Thus, you would need to mix 0.100 liters (or 100 mL) of the 15M NaNO3 solution with enough solvent (e.g., water) to bring the total volume to 250 mL in order to obtain a 6.0M NaNO3 solution.

Answer:
false
Explanation:
Simply put, a system is an organized collection of parts (or subsystems) that are highly integrated to accomplish an overall goal. The system has various inputs, which go through certain processes to produce certain outputs, which together, accomplish the overall desired goal for the system. A system is a collection of elements or components that are organized for a common purpose. The word sometimes describes the organization or plan itself (and is similar in meaning to method, as in "I have my own little system") and sometimes describes the parts in the system (as in "computer system"). A system is a group of interacting or interrelated entities that form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory. The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole concept made of several parts or members, system", literary "composition".

~Hello There!~
Considering that there are 100 cm in a meter, half of that would be 50.
Your answer is C. 50.
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
