Cr(NO3)3
because Chromium (III) formula is Cr2O3 And Nitrate formula is NO3
The sequence of coefficient that should be placed in the blank space to balance ii as follows
the sequence is 2 infront of Al 3 infront of O2 and 2 infront of Al2O3
that is 2Al +3O2 = 2Al2O3
from equation above 2 moles of Al reacted with 3 moles of O2 to form 2 moles of Al2O3
Answer:
Secondary
.
Explanation:
Primary amine contains only one alkyl group.
Secondary amine contains two alkyl groups.
Tertiary amine contains three alkyl groups.
- Since (C₆H₁₄)₂NH contains 2 alkyl groups.
<em>So, it is secondary amine.</em>
The atomic number increases by one and the element becomes a different element. <span>

Group 2 contains soft, silver metals that are less metallic in character than group 1 elements. There is a fairly strong conductivity trend within each row, left to right, and a weaker trend top to bottom. The elements in group 2 are moderately good conductors, while the elements on the right are very poor conductors. <span>As you move vertically between rows, conductivity decreases overall, but slowly.
Group 2 have a generally low electronegativity. Electronegativity decreases moving left and down across the table.</span>
