Answer:
A +1 Ion of Lithium
Explanation:
Lithium has the atomic number of 3, therefore it has 3 protons
An electron has a negative charge, so losing an electron gives an atom a positive charge.
Answer:
Dynamic
Explanation:
When rocks grind and squeeze past each other, dynamic metamorphism can occur.
Answer:
Explanation:
Percent ratio is the ratio of the actual yield to the theoretical yield. The formula is below.
The reaction of sodium and chlorine should theoretically yield 12.5 grams, but the actual yield was 13.0 grams.
- actual yield= 13.0 g
- theoretical yield = 12.5 g
Substitute these values into the formula.
Divide.
Multiply.
For this reaction, the percent yield is 104%
<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.
using the equation of formation of water:
H2+O2---->H2O
Balancing the equation,
2H2+O2---->2H2O
So now use the ratio from the balance equation, we know that 2 mol of H2 are producing 2 mol of H2O so the ratio will be 1:1.
So as 2 mol of H2O are produced by 2 mol of H2.
That implies 1 mol of H2O are produced by 1 mol of H2.
That is 0.253 mol of H2O are produced by 0.253 mol of H2.
