The laws of superposition and original horizontality are best applied to sedimentary rocks.
Sedimentary rocks are types of rocks that are formed through deposition and subsequent cementation of such material at the Earth's surface and within bodies of water. The law of superposition and original horizontality applies because technically the layers of sediments from which sedimentary rocks are formed were originally deposited horizontally under the gravitational action. Furthermore, since sedimentary rock formation has an undisturbed sequence, then the basic law of geochronolgy (law of superposition) applies since oldest layer is at the bottom while the youngest layer is on top.
Answer:
Here's what I get
Explanation:
1. Nickel sulfate
base + acid ⟶ salt + water
NiSO₄ is a salt of the base Ni(OH)₂ and the acid sulfuric acid.
Hydroxides of transition metals are insoluble; most sulfates are soluble.
2. Carbonate + acid
Most carbonates are insoluble.
They react with acids to form carbonic acid (H₂CO₃), which decomposes into water and carbon dioxide.

Explanation:
As we know 10.81 is the average atomic mass of boron which can not be contained by a single boron atom. Therefore, when isolated, a single boron atom will weight either 10 amu for ¹⁰B and 11 amu for ¹¹B respectively.
The average atomic mass is calculated as;
Atomic Mass of ¹⁰B = 10
Atomic Mass of ¹¹B = 11
Natural Abundance of ¹⁰B = 20 %
Natural Abundance of ¹¹B = 80 %
So,
Average Atomic Mass = (10 × 0.2) + (11 × 0.8)
Average Atomic Mass = 2 + 8.8
Average Atomic Mass = 10.8
Answer:
It is not dependent on the salt solute at all but the solute does have an affect.
Explanation:
in the equation you maybe aware of the I factor which represents the ions present in the solution. a non ionic will always have a I value of 1 a ionic can be 2 like in NaCl. What this means that all non ionic will lower the temperature depression but ionics will have a greater affect because for example salt breaks into Na and Cl will essentially hae more impurities than glucose which doesnt dissociate and will have a I value of 1
2 electrons on the first ring, 8 on the second, and 3 on the third ring
