Answer:polar covalent bond
Explanation:
Compounds are formed ether by donating, receiving or sharing of electrons making the bonds between them to be ionic, or covalent .
Now according to the rule of type of bond assignment due to electronegativity difference of atoms
---When the electronegativity difference is less than 0.5, the bond formed is nonpolar covalent.
---When the electronegativity difference is between 0.5 and 1.6, the bond is considered polar covalent
---When the electronegativity difference greater than 2.0, then the bond is ionic.
Therefore, When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bonded by polar covalent bond eg HCl bond , CCL4 bond
Answer:
C.)Air is made up of atoms of one elements
Elements are the same type of atoms, so there is nothing else to separate. Hydrogen has hydrogen atoms, and no other kind. Therefore nothing can be taken out of it anymore. Chemical x is a mixture, made by y and z. Nothing can make up y and z but themselves.
Answer:
The hydrogen ion concentration in a solution, [H+], in mol L-1, can be calculated if the pH of the solution is known.
pH is defined as the negative logarithm (to base 10) of the hydrogen ion concentration in mol L-1 pH = -log10[H+] ...
[H+] in mol L-1 can be calculated using the equation (formula): [H+] = 10-pH
Animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
