The answer is 88.86 g/mol
Answer:
A single compound reacts with itself.
Explanation:
Disproportionation is a chemical reaction,most times a redox reaction, in which a molecule is transformed into two or more dissimilar products. In a disproportionation reaction, the species are simultaneously oxidized and reduced to form at least two different products.
A typical example of a specie that disproportionate is the copper I ion as shown below;
2Cu^+(aq) ------> Cu(s) + Cu^2+(aq)
The two oxidation states of copper formed in the disproportionation are Cu(0) and copper (II).
The kind of magma that is found in the most explosive volcanoes, the composite volcanoes, is andesitic magma. It is magma that is quite high in silica content which makes it thick, sticky and gooey. Great lumps of this sticky magma cool at the top of the volcano to form a sealed cap. Magma beneath the cap builds up and pressure mounts and eventually becomes too much to be contained and the magma violently erupts out from the top, blowing out the cap and shooting miles up into the air and in all directions.
The kind of magma found in gentle volcanoes such as shield volcanoes is runny in consistency. It has very minimal amounts of silica and is not thick but loose. It therefore tends to trickle out of the top of the volcano rather than erupt or explode.
Answer:
13.1dm³
Explanation:
Given parameters:
Pressure of gas = 880mmHg
760mmHg = 1 atm
880mmHg will give 1.16atm
Temperature = 303k
Mass of gas = 26.9g
Molar mass of CO₂ = 12 + 2(32) = 44g/mol
Number of moles = mass/molar mass = 26.9/44 = 0.61mole
Unknown:
Volume of the sample = ?
Solution:
To solve this problem, we use the ideal gas equation:
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹k⁻¹
T is the temperature
V = 
= 
= 13.1dm³
