Answer:
-23.333 °C
Explanation:
(-10°F − 32) × 5/9 = -23.33°C
Answer:
No streak of light will appear.
Reason I given below.
Explanation:
No streak of light will be seen.
This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.
Answer:
a. BH₃
Explanation:
According to the octet rules, atoms reach stability when are surrounded by eight electrons in their valence shell when they combine to form a chemical compound.
From the options, the only compound in which the central atom does not meet the octet rules is BH₃. The central atom is boron (B), which has 3 electrons in its valence shell. When B is combined with hydrogen (H), 3 electrons from the 3 atoms of H are added. <em>The total amount of electrons is 6</em>, <em>fewer than 8 electrons</em> needed to meet the rule.
<span>The total number of nodes = n-1.
a) In your case for the 5 d orbital 5 - 1 = 4 nodes.
b) The l quantum number for a d orbital is 2. Therefore you will have 2 angular (planar) nodes.
c) You have 4 nodes, 2 of which are angular. Therefore, you will also have 2 radial nodes.</span>
