Ionic bond would form
e. g. NaCL
Answer:
3. Judgement may be affected by what we already think is true (prior knowledge).
Explanation:
This statement is the correct answer because someone could be bias. Due to biases, prior knowledge may be incorrect and our conclusion may be wrong if you don't focus on the data given.
CO₂ has 4 + 2(6) = 16 valence electrons
CO₂ have linear molecular structures with a 180° bond angle. CO₂ is nonpolar because the individual bond dipoles cancel each other out
XeCl₂ has 8 + 2(7) = 22 valence electrons.
There are five pairs of electrons about the central Xe atom. The structure will be based on a trigonal bipyramid geometry. The most stable arrangement of the atoms in XeCl₂ is a linear molecular structure with a 180° bond angle. It is nonpolar because the Xe−Cl bond dipoles and lone pairs around Xe are arranged in such a manner that they cancel each other out.
(b)
SCl₆ is nonpolar because it has 6 bonding pairs and no lone pairs, giving it an octahedral shape. When you draw the vectors, you can see that the resultant is 0, making it nonpolar.
SCl₄ on the other hand is polar because it has 4 bonding pairs and one lone pair, giving it a trigonal pyramidal shape.
SCl₂ is also polar due to reasons similar to those in the case of SCl₄.
CO(g) +2H2--->CH3OH
2.50g H2*1mol/2g=1.25 mol H2
30.0L CO*1mol/22.4L=1.34 mol CO,
according to reaction 1 mol CO needs 2 mol H2,so 1.34 mol CO need 2.68 mol H2, so 1) limiting teactant is H2 (H)
2)1.25 mol CH3OH will be produced, 1.25 mol*32g/mol=40.0 g CH3OH
3) 1.25 mol H2 needs 0.625 g CO
1.34-0.625=0.715 g CO leftover
Answer:
Fortunately, Earth retains heat fairly well, so humans wouldn't freeze instantly. Without the Sun's rays, all photosynthesis on Earth would stop. All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too.
