Based on the question, it is evident that this question rests on the premise of Charle's Law, which essentially states that temperature is proportional to volume once pressure and mass remain constant.

Thus by Charle's Equation:   \frac{ V_{1} }{ T_{1} }  =  \frac{ V_{2} }{ T_{2} }

Since the initial volume = 2.2 L; the initial temperature = 20 C; and the final volume = 2.6 L,
                           then V₁ = 2.2 L; T₁ = 20 C; V₂ = 2.6 L and what we would be
                           finding is T₂ (the final/new temperature)

Now,   T_{2}  =  \frac{(V_{2})   (T_{1}) }{V_{1}} 

     ⇒   T_{2}  =  \frac{(2.6 L)   (20  ^{o} C) }{2.2 L}

     ⇒   T_{2} = 23.64   ^{o}C


        ∴  the new temperature is ≈  23.6 °C

During chemical reactions the bonds between atoms break and new bonds form. Energy must be absorbed to break a bond, so breaking
ss7ja [257]

Answer:

The equation is: CuCO3(s) → CuO(s) + CO2(g)

Explanation:

Copper carbonate decomposes at high temperatures, generating the products carbon dioxide (CO2) and copper oxide (II) CuO. In this type of decomposition reaction, a substance is broken generating two different compounds.

Answer:

Condensation

Explanation:

An exothermic process is one in which heat is lost. Condensation is a change of state from gas to liquid. Thus is loses heat.

An atom of which of these elements most likely forms an anion? A. AI B. Br C. Ca D. Mg
Papessa [141]
The answer is B. A good way determine this is how far right the element is on the periodic table. The further right the element is, the more electronegative it is meaning it is more willing to accept an electron. This can be explained using the valence electrons and how many need to be added or removed to complete the octet. The further right you are, the easier it is for the element to just gain a few electrons instead of loose a bunch. Noble gases are the exception to this since they don't normally react though.

The question is below
rodikova [14]
The anode is the electrode where the oxidation occurs.

Cathode is the electrode where the reducction occurs.

Equations:

  Mn(2+) + 2e-  --->  Mn(s)                      Eo = - 1.18 V
2Fe(3+) + 2e-  ----> 2 Fe(2+)                2Eo = + 1.54 V

The electrons flow from the electrode with the lower Eo to the electrode with the higher Eo yielding to a positive voltage.

Eo = 1.54 V - (- 1.18) = 1.54 + 1.18 = 2.72

Answer: 2.72 V

How many electrons will a metal generally have in its outer energy level?
Zarrin [17]

Answer:

Metals have one or two electrons in their outermost shell

C. 1-2

Explanation:

  • Metals have low ionisation energy because they easily looses the outermost electrons
  • They have only one- two electrons in the outer most shell.
  • They loose these electron to form charged species called cation.
