Answer : A single carbon atom can form a maximum of <u>Four (4)</u> covalent bond(s).
Explanation : A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
Formation of covalent bond depends on the number of valence electrons. Electronic configuration of Carbon (C) is :
Valence electronic configuration of C is :
Carbon have four valence electron that means Carbon can form maximum of four covalent bonds.
For example : In methane (CH4) Cabon can share four electrons with four Hydrogen atoms and can form four covalent bonds with 4 H.
Answer:
C) CH4 (g) + O2 (g)→ CO2 (g) + H2O (g)
Explanation:
Methane burns in the presence of air to give carbondioxide and water.
Also, All Alkanes combust in the presence of Oxygen to give carbondioxide and water.
Answer: The answer is B) 1.00 M CaCl2
Explanation: I just did it on usatestprep and it said it was correct .
Answer:
6.69 moles
Explanation:
Data obtained from the question include:
Volume = 2230mL
Molarity of NaOH = 3 M
First, we'll convert 2230mL to L. This is illustrated below:
1000mL = 1L
2230mL = 2230/1000 = 2.23L
Now, we can obtain the number of mole of NaOH in the solution as follow:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole of NaOH = 3 x 2.23
Mole of NaOH = 6.69 moles
Therefore, the total number of mole of the solute (NaOH) in the solution is 6.69 moles
