Answer:
0.43 g/ml
Explanation: Density is d = M/V, where d is density, M is mass, and V is volume: therefore d= 32 g/75ml = 0.4266 = 0.43 g/ml
Since no choices are given, I would just give the 6 possible tetrahedron structures of silicate minerals. Then, it will be up to you to distinguish which one fits to your choices.
1. Isolated tetrahedra - they are separated by positive charges. An example would be olivine.
2. Ringed tetrahedra - they are linked together by positive charges, like that of tourmaline.
3. Tetrahedra - oxygen is shared by two neighbors like that of the pyroxene family.
4. Double chains/Ribbons - example whould be the amphibole family
5. Silica Sheets - when oxygen is shared by three adjacent molecules like the micas and the clay minerals.
6. Three-dimensional framework - four oxygen atoms are linked to other tetrahedra like feldspar and quartz.
Answer:
a. .250 moles
Explanation:
Hello!
In this case, since we can see how the hydrogen is given off as a product of the reaction and we can model its behavior via the ideal gas equation, it is possible for us to use such equation for the determination of the collected moles:
Next, since the STP conditions account for a pressure of 1 atm and a temperature of 273 K, the moles turn out to be:
Thus the answer is a. .250 moles
.
Best regards!
Answer:
Water has strong hydrogen bond dipole-dipole intermolecular forces that give water a high surface tension and a high heat of vaporization and that make it a strong solvent.
Explanation:
water-gas shift membrane reactor(WGSM)
Explanation:
The major component in the processing train for fuel cells is the water-gas shift membrane reactors. Fuel cells offer a very clean and environmental source of energy production. They are usually tagged the future of energy production in the world.
- Unlike the internal combustion systems that uses fossil fuels to produce energy, the water-gas shift membrane reactor allows for the production of energy using the combination of oxygen and hydrogen in the presence of a catalyst.
- In the reactor, hydrogen gas is a able to readily diffuse out while the other components are unable to do so.
