Well, depending on the charge, it could be Cu; if it has a charge of 2+
Answer:
Pi bond
Explanation:
Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.
The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.
Answer:
Q = -1.318 KJ
Explanation:
We will use the assumption that this solution acts like water and thus we will use the specific heat capacity of water and when converting from mL to g, we will use the conversion like we do for water.
We are told that 50 mL of HCl reacts with 100 mL of NaOH.
Thus total mass; m = 50 + 100 = 150 mL
Converting to grams gives 150 g since we have assumed that the solution behaves like water.
We are given;
Initial temperature; T_i = 21.3° C
Final temperature; T_f = 23.4° C
ΔT = 23.4 - 21.3
ΔT = 2.1°C
Formula for quantity of heat is;
Q = mcΔT
c is specific heat capacity.
We will use c = 4.184 J/g°C since the solution is assumed to behave like water.
Thus;
Q = -(150 × 2.1 × 4.184)
Q = -1317.96 J
Negative sign is used because temperature was raised and thus reaction is exothermic.
Approximation to KJ gives; -1.318 KJ
Answer:
Therefore, 2 moles of oxygen will be required to oxidize 2.66 moles of oxygen. 72g of Aluminium will be completely oxidized by 44.8 lit of oxygen at STP.
