<h2>Rocks are grouped according to their formation into three major groups – igneous, sedimentary, and metamorphic rocks
</h2>
Explanation:
- Based on their formation, rocks are further sub-grouped as:
- Igneous - Intrusive or extrusive
- Sedimentary – Clastic, chemical, or biologic rocks
- Metamorphic - Foliated and non-foliated
- Rocks are also grouped based on their properties like size, shape, texture, chemical composition, permeability, mineralogy, etc.
- Based on properties rocks are sub-grouped as:
- Igneous rocks – coarse or fine-grained; glassy or obsidian; felsic or mafic.
- Sedimentary rocks - conglomerate, sandstone, breccia, shale, siltstone, chalk, crystalline or fossiliferous limestone, gypsum, rock salt etc.
- Metamorphic rocks - Gneiss, hornfels, mylonites, cataclasties, marble, etc.
Here we have to get the amount of propane can be produced from the reaction of 1.7 moles of carbon (C).
1.7 moles of carbon will produce 0.425 moles of propane
In the reaction 8 moles of carbon is producing 2 moles of propane. Thus, mathematically,
8C → 2C₃H₈
Thus 8 moles of carbon produces 2 moles of propane
1.7 moles of carbon produces ×1.7 = 0.425 moles
Thus 1.7 moles of carbon will produce 0.425 moles of propane.
Thus the amount of propane will be prepared from the reaction of 1.7 moles of carbon is determined.
Answer:
Oxygen is more electronegative.
Explanation:
Electronegativity:
Electronegativity of an atom is its tendency to attract the electron to wards it self.
Br = 2.98
O = 3.44
Oxygen is more electronegative than bromine thus it attract electron more strongly towards itself as compared to bromine.
when an more electronegative atom combine with less electroneagtive atom partial charges are created upon them. e.g
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
At room temperature:
a. Gold is a solid, as in the gold jewelry that most people have.
b. Gasoline is a liquid, as it is pumped in cars to use as fuel.
c. Oxygen is a gas, as we breathe it in from the atmosphere.
d. Neon is a gas, it is one of the noble gases in the periodic table.
e. Olive oil is a liquid, as it is used in cooking.
f. Sulfur is a solid, and it can be found naturally in mining.
g. Mercury is a liquid which is often seen in thermometers.
