Answer:
The Industrial Revolution was a period of great industrialization that began in the late 18th century in Britain, leading to massive population growth and agricultural innovations, which laid the foundation for increased productivity, both with increased labor and a larger market for the products. There was a revolution in the production methods of the textile industry, especially with the advent of the steam engine and urban development, the influx of people from the countryside to the cities meant that there was an abundance of labor, which laid the foundation for the industrial cities of the nineteenth century. The steam engine was also used in the new generation of transport, in locomotives and steamships. With the advent of steel as a building material along with a series of new discoveries in communication technology in the second half of the 19th century, the tone was set for the continued technological development of the 20th century.
With dish soap baking soda and contact solution
I would say carbon monoxide
Firstly because the image shows two different atoms bonded so it cannot be nitrogen or krypton
Secondly sulphur dioxide has 3 atoms bonded (two oxygens and a sulphur atom) so it can’t be that
Finally it can’t be hydrogen chloride because chloride is significantly larger than hydrogen
Thus it must be carbon monoxide as carbon and oxygen are bonded (CO) and are both relatively similar in size
Answer:
Number of moles = 3.82 mol
Explanation:
Given data:
Number of moles of CO₂ = ?
Mass of CO₂ = 168.2 g
Solution:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
By putting values,
Number of moles = 168.2 g/ 44 g/mol
Number of moles = 3.82 mol
Answer:
Moles of water in 7.1×10²⁵ molecules are 118 mol.
Explanation:
Given data:
Number of molecules of water = 7.1×10²⁵ molecules
Moles of water in 7.1×10²⁵ molecules = ?
Solution;
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1 mole = 6.022 × 10²³ molecules of water
7.1×10²⁵ molecules of water × 1 mol / 6.022 × 10²³ molecules of water
1.18×10² moles of water 0r 118 moles of water
