Holding temperature and pressure constant, what is the most important feature in determining the phase of a given organic compou
Leni [432]
Holding temperature and pressure constant <span>the most important feature in determining the phase of a given organic compound is pressure. ransfers of organic compounds between phases are controlled by molecular interactions (intermolecular bonding) in the two phases between which transfer is occurring. This is governed by temperature and pressure</span>

the specific heat of the metallic element rhodium is 0.240 j/g-k at 25°c. if 586 j of heat is added to an 80.0 g block of rhodiu
andrey2020 [161]

The expected final temperature of the block, given that 586 J of heat were added to it is 55.5 °C

<h3>How to determine the final temeprature</h3>

We'll begin by obtaining the change in the temperature of the block. This can be obtained as follow:

  • Specific heat capacity of block (C) = 0.240 J/gºC
  • Heat added (Q) = 586 J
  • Mass of block (M) = 80.0 g
  • Change in temperature (ΔT) =?

Q = MCΔT

Divide both sides by MC

ΔT = Q / MC

ΔT = 586 / (80.0 × 0.240)

ΔT = 586 / 19.2

ΔT = 30.5 °C

Finally, we shall determine the final temperature of the block. This can be obtained as follow:

  • Initial temperature (T₁) = 25 °C
  • Change in temperature (ΔT) = 30.5 °C
  • Final temperature (T₂) = ?

ΔT = T₂ – T₁

30.5 = T₂ – 25

Collect like terms

T₂ = 30.5 + 25

T₂ = 55.5 °C

Thus, from the calculation made above, we can conclude that the final temperature is 55.5 °C

Calculate the empirical formula of a compound that is 42.9% Carbon and 57.1% Oxygen.
Marrrta [24]

Answer:

CO.

Explanation:

Assuming the given percentages are by mass, we can solve this problem via imagining we have <em>100 g of the compound</em>, if that were the case we would have:

  • 42.9 g of C
  • 57.1 g of O

Now we <u>convert those masses into moles</u>, using the<em> elements' respective molar masses</em>:

  • 42.9 g of C ÷ 12 g/mol =  3.57 mol C
  • 57.1 g of O ÷ 16 g/mol =  3.58 mol O

As the number of C moles and O moles is roughly the same, the empirical formula for the compound is <em>CO</em>.

what is the balanced equation for the reaction of solid magnesium metal with oxygen gas to produce solid magnesium oxide
GaryK [48]

Answer:

2Mg + O₂ ⟶ 2MgO

Explanation:

Step 1. Start with the most complicated-looking formula (O₂?).

Put a 1 in front of it.

Mg + 1O₂ ⟶ MgO

Step 2. Balance O.

We have fixed 2 O on the left. We need 2O on the right. Put a 2 in front of MgO.

Mg + 1O₂ ⟶ 2MgO

Step 3. Balance Mg.

We have fixed 2 Mg on the right-hand side. We need 2 Mg atoms on the left. Put a 2 in front of Mg.

2Mg + 1O₂ ⟶ 2MgO

Every formula now has a coefficient. The equation should be balanced. Let’s check.

<u>Atom</u>  <u>On the left</u>  <u>On the righ</u>t

  Mg             2                  2

  O                2                  2

All atoms are balanced.

The balanced equation is

2Mg + O₂ ⟶ 2MgO
