A compound contains 1.10 mol of K, 0.55 mol of Te, and 1.65 mol of O. What is the simplest formula of this compound?

sergiy2304 [10]

Answer:

$K_2TeO_3$

Explanation:

Given that:-

Moles of K = 1.10 moles

Moles of Te = 0.55 moles

Moles of O = 1.65 moles

Taking the simplest ratio of the moles of the elements as:-

K : Te : O

1.10 : 0.55 : 1.65

2 : 1 : 3

Empirical formulas is the simplest or reduced ratio of the elements in the compound. So, the empirical formula is:- $K_2TeO_3$

What entropy change is associated with the reversible phase change from 1.0kg of ice to water at 0 ° C?

avanturin [10]

Answer:

1200 J/K

Explanation:

The formula for the entropy associated with a reversible phase change is

$\Delta S= \dfrac{q_{\text{rev}}}{T}$

1. Calculate q

For a reversible phase change like melting,

$q_{\text{rev}} = m\Delta_{\text{fus}}H = \text{1000 g} \times \dfrac{\text{334 J}}{\text{1 g}} = \text{334 000 J}$

2. Calculate ΔS

$\Delta S = \dfrac{q_{\text{rev}}}{T} =\dfrac{\text{334 000 J}}{\text{273.15 K}} = \textbf{1200 J/K}$

If hershey and chase had used radioactive oxygen in their experiments instead of phosphorus and sulfur, what results would they

Ugo [173]

The real situation with this is that if since both proteins and DNA contain carbon and oxygen, both molecules in the phage progeny would have received the radioactive isotopes. Hershey and Chase would have been unable to isolate only DNA molecules or proteins that contain the radioactive isotopes of these elements.
