Which of these is not characteristic of carbon?
2 answers:
Answer:
Option d
Explanation:
Carbon is a non-metal. Atomic number of carbon is 6.
Electronic configuration of C =
Its outer shell has 4 valence electrons. Carbon forms covalent bond by sharing its valence electrons. So, carbon completes its octate by sharing its four valence electrons.
Catenation is the characterisctics property of carbon. Catenation is the property of elements in which atoms of same element bond with itself in a series to form long chain.
Elements usually form bond in order to attain stability.
Carbon does not form ionic bond, as removal of 4 electrons or gain of 4 electrons is not possible in order to attain inert gas configuration.

Answer: There are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.
Explanation:
Given: = 0.0023 M,
= ?
= 15.0 mL,
= 0.012 M
Formula used to calculate volume of strontium hydroxide solution is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.
