Answer:

3.88g/mL

Explanation:

Density could be understood as the mass of a compound when it occupies 1mL.

To find the mass in 1mL we need to determine the volume that the piece occupies:

Based on Archimedes' principle, the volume of water displaced is equal to volume of the aluminium piece, that is:

54.4mL - 41.8mL = 12.6mL

As the piece has as mass 48.9g, the density is:

48.9g / 12.6mL =

<h3>3.88g/mL</h3>

The rate of reaction is fastest at the _______ of a chemical reaction
astraxan [27]

Answer:

Beginning or Start

Explanation:

Reactions can be followed by measuring changes in concentration, mass and volume of reactants or products. The rate is highest at the start of the reaction because the concentration of reactants is highest at this point.

Draw the structural formula of the major product of the reaction of (S)-2,2,3-trimethyloxirane with MeOH, H . Use the wedge/hash
Katarina [22]

Answer:

(S)-3-methoxy-3-methylbutan-2-ol

Explanation:

In this case, we have an <u>epoxide opening in acid medium</u>. The first step then is the <u>protonation of the oxygen</u>. Then the epoxide is broken to generate the most <u>stable carbocation</u>. The nucleophile (CH_3OH) will attack the carbocation generating a new bond. Finally, the oxygen is <u>deprotonated</u> to obtain an ether functional group and we will obtain the molecule <u>(S)-3-methoxy-3-methylbutan-2-ol</u>.

See figure 1

I hope it helps!

. Is it possible to have an oxygen atom with 8 protons and another oxygen atom with 9 protons? Explain.
Scorpion4ik [409]

Answer:

no

Explanation:

changing the number of protons will change the atomic number, and if the atomic number is changed, it will become a different element. if you give oxygen 9 protons, it would no longer be oxygen, it would be fluoride.

Fill in the blank:
Roman55 [17]

Answer:

Weathering, Erosion

Explanation:

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.

Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.

Hope this helps

All the love, Ya boi Fraser :)
