4 0

Sodium sulfate is the inorganic compound with formula Na2SO4 as well as several related hydrates. All forms are white solids that are highly soluble in water. ... Sodium sulfate displays a moderate tendency to form double salts. .... phase change from solid to liquid, and the advantageous phase change temperature of 32 °C

Calculate the molar mass of RbOH
Ghella [55]

Hey there!

RbOH

Rb: 1 x 85.468 = 85.468

O:  1 x 16 = 16

H: 1 x 1.008 = 1.008

------------------------------------

                   102.476

The molar mass of RbOH is 102.476 g/mol.

Hope this helps!

1. How many covalent bonds are expected to form from phosphorus in order to obey the octet rule?
Grace [21]
To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.

Equation is balanced already
mojhsa [17]

Answer:

1.) 13 g C₄H₁₀

2.) 41 g CO₂

Explanation:

To find the mass of propane (C₄H₁₀) and carbon dioxide (CO₂), you need to (1) convert mass O₂ to moles O₂ (via molar mass), then (2) convert moles O₂ to moles C₄H₁₀/CO₂ (via mole-to-mole ratio from equation coefficients), and then (3) convert moles C₄H₁₀/CO₂ to mass C₄H₁₀/CO₂ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answers should have 2 sig figs to match the sig figs of the given value.

Molar Mass (C₄H₁₀): 4(12.011 g/mol) + 10(1.008 g/mol)

Molar Mass (C₄H₁₀): 58.124 g/mol

Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)

Molar Mass (CO₂): 44.007 g/mol

Molar Mass (O₂): 2(15.998 g/mol)

Molar Mass (O₂): 31.996 g/mol

2 C₄H₁₀ + 13 O₂ ----> 8 CO₂ + 10 H₂O

 48 g O₂             1 mole             2 moles C₄H₁₀            58.124 g

What is the redox reaction? And how does the redox reaction happen inside batteries?
Montano1993 [528]

Answer:

It is called a reduction-oxidation, oxide-reduction reaction, or simply as a redox reaction, any chemical reaction in which one or more electrons are transferred between the reactants

Redox battery is an example of both a Flow Battery and a two electrolyte system.In this case, it depends on two different active aqueous electrolytes of vanadium dissolved in sulfuric acid separated by a membrane at which ionic interchange takes place.

Thats my opinión though.
