Answer:
a. The atom will go from a two-dimensional configuration to a three dimensional configuration.
d. The bond angle will increase.
f. The number of unhybridized p orbitals will decrease.
Explanation:
Sp2 is the atomic bond in which orbitals mixes with only two orbitals. These orbitals form three sp2. When two carbon atoms are overlapped they form sigma bond by overlapping of sp2 bonds. Sp3 bond is created when there is one lone molecule available for combination. When the bonding is updated from sp2 to sp3 then unhybridized orbitals will decrease causing the bond angle to increase.
The density of water is a physical property.
You can measure it without changing the water to a different substance.
It is <em>not a physical change</em> because the water does not change to ice or steam.
You can observe a <em>chemical property</em> or a <em>chemical change</em> only if the water <em>changes to a different substance</em>.
Assume 100 g of compound. This turns percent to mass. Calculate moles:
S ---> 30/32 = 0.9375
F ---> 70 / 19 = 3.6842
get whole number ratio:
0.9375 / 0.9375 = 1
3.6842 / 0.9375 = 3.93 = 4
Answer : SF4
No because your body can't take that much salt
Answer:
The footprints of a dinosaur and the burrow of an ancient shrimp are examples of - Trace Fossils
Explanation:
A trace fossil or ichnofossil is defined as a geological record of biological activity. These provide us with indirect evidence of life in the past, such as the footprints, burrows, tracks, borings, etc that are left behind by animals, rather than the preserved remains of the body of the actual animal itself.
