7 0

Answer:

Zn + 2HCl → ZnCl2 + H2

Explanation:

Zn + HCl → ZnCl2 +

The complete equation is given below:

Zn+ HCl → ZnCl2 + H2

Now we can balance the equation by doing the following:

There are 2 atoms of Cl and 2 atoms of H on the left. This can be balanced by putting 2 in front of HCl as shown below:

Zn + 2HCl → ZnCl2 + H2

A sample of octane burns releasing 2290 J of heat to the surroundings, and the gases produced expands against a piston to do 560
dexar [7]

<u>Answer:</u> The internal energy change for the reaction is -2850 J

<u>Explanation:</u>

  • <u>Sign convention of heat:</u>

When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.

  • <u>Sign convention of work:</u>

Work done for expansion process is taken as negative and work done for compression is taken as positive.

According to the First law of thermodynamics,

\Delta U=q+w

where,

\Delta U = internal energy

q = heat absorbed or released  = -2290 J

w = work done = -560 J

Putting values in above equation, we get:

\Delta U=(-2290)+(-560)\\\\\Delta U=-2850J

Hence, the internal energy change for the reaction is -2850 J

QveST [7]

Answer:

Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus

Explanation:

<u>Organelles</u> are membrane bound only in eukaryotic ccells.

Prokaryotic cells unlike eukaryotic cells, do <u>not have membrane bound organlles.</u>

Something that is found in <u>both prokaryotic and eukaryotic cells is the cytoplasm</u>, which is fluid that is inside the whole cell.

Unlike eukaryotic cells, <u>prokaryotic cells have loose DNA</u>, which floats around the cell quite literally.

The only way DNA is stored in eukaroyotic cells is in the <u>nucelus</u>, which is only found in eukaryotic cells, not prokaryotic.

Hope this helps ;)
