Answer:
Polar and bent
Explanation:
It looks like you are trying to find the polarity of H-O-H.
Its Lewis structure is shown in the first diagram below.
It has two lone pairs and two bonding pairs, so it is an AX₂E₂ molecule and its molecular shape is bent, as in the second diagram.
O is much more electronegative than H, so the O-H bond is highly polar. The O atom is at the negative end, and the H atom is at the positive end.
The centre of negative charge is on the O atom, and the centre of negative charge is halfway between the two H atoms, so the molecule has a net dipole pointing "up" in the picture.
Thus, H-O-H has polar bonds and is a polar molecule.
Answer:
Oxidation Number of Phosphorous = + 6
Explanation:
According to Rules of Assigning Oxidation States;
i) The Oxidation State of Hydrogen atom in a compound is assigned as +1 except for Hydrides i.e. NaH and MgH₂ where it is assigned with -1.
ii) The Oxidation State of Oxygen in a compound is assigned as -2 except for Peroxides where it is given -1 and OF₂ where it is assigned with +1 respectively.
Oxidation State of P in H₂P₃O₁₀;
As over all molecule is neutral we can write it as,
H₂P₃O₁₀ = 0
Putting oxidation number of H and O,
(+1)₂ + P₃ + (-2)₁₀ = 0
(+2) + P₃ + (-20) = 0
+ 2 + (P)3 -20 = 0
(P)3 = + 20 - 2
(P)3 = + 18
P = + 18 ÷ 3
P = + 6
Answer:
Exothermic
Explanation:
Exothermic describes a process or reaction that releases energy
Science experiments usually include an independent variable, dependent variable, and control. ... Science experiments also include something called constants. A constant is the part that doesn't change during the experiment.
