Answer:
B
Explanation:
best way to put off the fire
Answer:
Lower.
Explanation:
Viscosity means thickness or consistency. Picture how sticky and dense chocolate syrup is compared to orange juice--syrup is more viscous.
Other examples - high viscosity = molasses, low viscosity = water.
It’s c you are a lot better I am I have a good idea of how to you
Answer:
27.6 %.
Explanation:
- Acetone has the molecular formula (C₃H₆O).
- The molar mass of acetone is the summation of the atomic mass of the elements forming it multiplied by its number of atoms.
Atomic mass of C = 12.011 g/mol.
Atomic mass of H = 1.008 g/mol.
Atomic mass of O = 15.999 g/mol.
- The molar mass of acetone = [(3 x atomic mass of C) + (6 x atomic mass of H) + (Atomic mass of O)] = [(3 x 12.011 g/mol) + (6x 1.008 g/mol) + (15.999 g/mol)] = 58.08 g/mol.
- The mass % of any element = [(no, of the element atoms x atomic mass of the element) / molar mass of the compound] x 100.
∴ The mass % of O = (Atomic mass of O / molar mass of acetone) x 100 = [(15.999 g/mol) / (58.08 g/mol)] = 27.6 %.
From the above statement, John can infer that the rock underwent metamorphism and also is not altered by heat or pressure.
<u>Explanation</u>:
- Metamorphic rock is an igneous sedimentary rock and although when put through heat the rock becomes hot but does not alter its shape or melt. If the rock melts then it is only an igneous rock and not a sedimentary one.
- During metamorphism, the chemical and the mineral content of prolith are changed due to changes in the environment based on physical and chemical conditions.
- Even though the rocks remain solid, fluid is present between the macroscopic spaces.
- This gives "The Geologist" accurate information of what happens beneath the earth during the formation of mountains.
- Metamorphic rocks are like probes that go down the earth and comes back giving information of what happens underneath the surface.
