Answer:
Models help scientists understand processes in the natural world by providing simpler representations of those processes.
Answer:
Empirical formula: CH₃O
Empirical formula mass = 31 g/mol
Explanation:
Data Given:
Molecular Formula = C₁₀H₃₀O₁₀
Empirical Formula = ?
Empirical Formula mass =
Solution
Empirical Formula:
Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.
So,
The ratio of the molecular formula should be divided by whole number to get the simplest ratio of molecule
As
C₁₀H₃₀O₁₀ Consist of 10 Carbon (C) atoms, 30 Hydrogen (H) atoms, and 10 Oxygen (O) atoms.
Now
Look at the ratio of these three atoms in the compound
C : H : O
10 : 30 : 10
Divide the ratio by two to get simplest ratio
C : H : O
10/10 : 30/10 : 10/10
1 : 3 : 1
So for the empirical formula the simplest ratio of carbon to hydrogen to oxygen is 1:3:1
So the empirical formula will be
Empirical formula of C₁₀H₃₀O₁₀ = CH₃O
Now
To find the empirical formula mass in g/mol
Formula mass:
Formula mass is the total sum of the atomic masses of all the atoms present in a formula unit.
**Note:
if we represent the molar mass of the empirical formula for one mol in grams then it is written as g/mol
So,
As the empirical formula of C₁₀H₃₀O₁₀ is CH₃O
Then Its empirical formula mass will be
CH₃O
Atomic Mass of C = 12
Atomic Mass of H = 3
Atomic Mass of O = 16
Total Molar mass of CH₃O
CH₃O = 12 + 3(1) + 16
CH₃O = 12 + 3 + 16
CH₃O = 31 g/mol
Explanation:
(A) Renewable resources are defined as the resources that can be used again and again.
For example, wind, hydroelectric energy, geothermal etc.
On the other hand, resources which cannot be used again and again and which cannot be replaced by natural means are known as non-renewable resources.
For example, coal, petroleum etc are all non-renewable resources.
Therefore, given options are distinguished as follows.
Renewable energy : Wind, Hydroelectric, Geothermal, Biomass, and Solar.
Non-renewable energy : Coal, Petroleum, Natural gas.
(B) Fuels which decompose for a long period of time and which arise from old life forms are known as fossil fuels.
When fossil fuels burn in the presence of air that is, combustion of fossil fuels give carbon dioxide and water.
Answer:
Rubber, or another insulator.
Explanation:
I'm not sure what the options are, but Sue would probably want an insulator so that the heat is trapped, keeping her hands cool.
Answer:
the three products of destructive distillation of coal are:-
1. coal gas
2. coke
3. ammonia liquor
