Answer:
Explanation:
Hello,
In this case, for the proposed question, we should notice that the moles of sodium fluoride and strontium chloride, must be in stoichiometric proportions, that is 1:2 respectively, based on the given chemical reaction, for that reason, we first compute the available moles of strontium chloride based on the statement:
Now, based on the reaction, the moles of sodium fluoride which will complete react result:
Finally, by using the molarity of the sodium fluoride solution, we compute the required volume of such solution:
Best regards.

Answer:
Explanation:
An electrophilic addition reaction occurs when an electrophile attacks a substrate, with the end result being the inclusion of one or many comparatively straightforward molecules along with multiple bonds.
In the given question, the hydrogen bromide provides the electrophile while the bromide is the nucleophile. The mechanism proceeds with the attack of the electrophile on the carbon, followed by deprotonation. This process is continued with a formation of carbocation and the bromide(nucleophile) finally bonds to the carbocation to form a stable product.
The first diagram showcases the possible various starting molecules for the synthesis while the second diagram illustrates their mechanism.
Answer: A volume of 455 mL from 0.550 M KBr solution can be made from 100.0 mL of 2.50 M KBr.
Explanation:
Given: = ?,
= 0.55 M
= 100.0 mL,
= 2.50 M
Formula used to calculate the volume of KBr is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that a volume of 455 mL from 0.550 M KBr solution can be made from 100.0 mL of 2.50 M KBr.
The correct statement is " A single bond, because they overlap orbitals to share one pair of electrons." A fluorine atom is unstable with 7 electrons in its valence shell and so needs one more electron to achieve stability. This is according to the octet rule which states that an atom will gain or lose electrons until there are 8 electrons in its valence shell. So each fluorine donates an electron to form a single pair and the achieves a noble gas configuration.
