Temperature and silica content determine the _______ of magma.

Chemistry
1 answer:
mr_godi [17]3 years ago
7 0
<span>I think the correct answer is that they can determine the viscosity of the magma. The viscosity of a magma is largely controlled by the temperature, composition and the gas content. Also, silica content can define a magma type. It is said that higher silica content magma has a higher viscosity than those with lower silica content.</span>

Based on the following thermodynamic data, calculate the boiling point of ethanol in degrees Celsius. Substance ΔH∘f (kJ/mol) S∘
levacccp [35]

Answer:

76.03 °C.

Explanation:

Equation:

C2H5OH(l) --> C2H5OH(g)

ΔHvaporization = ΔH(products) - ΔH (reactants)

= (-235.1 kJ/mol) - (-277.7 kK/mol)

= 42.6 kJ/mol.

ΔSvaporization = ΔS(products) - ΔS(reactants)

= 282.6 J/K.mol - 160.6 J/K.mol

= 122 J/K.mol

= 0.122 kJ/K.mol

Using gibbs free energy equation,

ΔG = ΔH - TΔS

ΔG = 0,

T = ΔH/ΔS

T = 42.6/0.122

= 349.18 K.

Coverting Kelvin to °C,

= 349.18 - 273.15

= 76.03 °C.

Why is gold considered matter?
Yakvenalex [24]

Answer:

All matter is made up of substances called elements, which have specific chemical and physical properties and can't be broken down into other substances through ordinary chemical reactions. Gold, in this case, is an element so, therefore, it is considered matter.

Hope it helped :)

what is the concentration (molarity) of a solution where 149g of kcl is dissolved in enough water to get a total volume of the s
Anit [1.1K]
Molar mass KCl = 74.55 g/mol

Number of moles:

mass KC / molar mass

149 / 74.55 => 1.998 moles 

Volume in liters: 500 mL / 1000 => 0.5 L 

Therefore:

M = moles / volume

M = 1.998 / 0.5

M = 3.996 mol/L⁻¹
