The formula for europium oxide is Eu203. On the basis of this information, the formula for the chlorate of europium would be exp
lina2011 [118]

Answer:

Eu(ClO3)3

Explanation:

The chlorate ion is written as follows, ClO⁻ ₃. We can see from this that the ion is univalent.

From the formula, Eu203, it is easy to see that the europium ion is trivalent.

Hence, when a compound is formed between the europium ion and chlorate ion, the compound will be written as Eu(ClO3)3.

This is so because, when ionic compounds are formed, there is an exchange of valence between the ions in the compound. This gives the final formula of the ionic substance.

Lipoamide is a covalently attached coenzyme that plays a key role in several decarboxylase reactions, including glycine decarbox
Reika [66]

Answer:

Lysine 63.

Explanation:

The coenzyme may be defined as the non protein part of an enzyme that plays an important role in the enzyme functioning. Any cation or small molecule like amino acids can acts as coenzyme.

Lipoamide is important coenzyme that plays an important role in the metabolic pathways by undergoes the decarboxylation reactions. The reduced lipoamide known as dihydrolipoamide is used for the covalent attachment at Lysine 63 residues.

Thus, the correct answer is option (D).

530 mL of CO gas at a pressure of 1.2 atm and a temperature of 17ºC. What is the volume of the gas at 0ºC and 1 atm?
Kryger [21]

Answer:

598.74 mL

Explanation:

Using Ideal gas equation for same mole of gas as

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

Given ,  

V₁ = 530 mL

V₂ = ?

P₁ = 1.2 atm

P₂ = 1 atm

T₁ = 17 ºC

T₂ = 0 ºC

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (17 + 273.15) K = 290.15 K  

T₂ = (0 + 273.15) K = 273.15 K  

Using above equation as:

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

\frac {{1.2}\times {530}}{290.15}=\frac {{1}\times {V_2}}{273.15}

Solving for V₂ , we get:

<u>V₂ = 598.74 mL</u>

How does the shape of a molecule affect the polarity of the molecule
vodomira [7]

Answer: The shape of a molecule affects polarity because of how bond dipoles between two atoms is affected by other atoms in the molecule. Bond dipoles are vector quantities (which means they have magnitude and direction), so when a molecule has two or more bond dipoles they can cancel each other out if they perfectly oppose each other. For example CO2 (O=C=O) has two dipole bonds, but since they equaly oppose each other they cancel out and the molecule is nonpolar. In bent molecules like H2O, the two hydrogens bonded to the oxygen have equal dipole moments, but they do not directly oppose each other so they do not cancel out. As a result the molecule is polar. So in summary the molecule's geometry affects the polarity of the molecule by dictating the direction of the vector quantities of the dipole bonds, which determines whether they will be able to cancel each other out (nonpolar) or allow for non zero dipole moments (polar).
