I’m not 100% positive but quartz would make sense
I only know #8 and the raindrop would increase speed due to gravity.
The bonds that are present in the pictured compound are C −C and C −H.
<h3>What is a bond?</h3>
A bond is that which connects two atoms together. We know that a compound is composed of bonds. There are a number of bonds in a compound. The bonds are always as many as the atoms that need to be linked in the compound.
We know that butane a shown in the image is an alkane. An alkane has carbon - carbon and hydrogen - carbon bonds. There are no multiple bonds in the compound butane.
Thus, the bonds that are present in the pictured compound are C −C and C −H.

Answer:
Final T° is 45.5°C
Explanation:
Formula for calorimetry is:
Q = m . C . ΔT , where
ΔT = Final T° - Initial T°
C = Specific heat
m = mass
Let's replace with the data given
305 J = 93.4 g . 0.128 J/g°C . (Final T° - 20°C)
305 J / 93.4 g . 0.128 J/g°C = Final T° - 20°C
25.5°C = Final T° - 20°C → Final T° = 25.5°C + 20°C = 45.5°C
Answer:
This is a synthesis reaction.
Explanation:
This is because nothing is being swapped out, reactants are being combined and then form a product.
