Not sure what you mean here but:
Fe x 3
H x 8
O x 4
Answer:
0.036 × 10²³ oxygen atoms
Explanation:
Given data:
Mass of compound = 0.24 g
Number of oxygen atoms = ?
Solution:
First of all we will calculate the number of moles of compound.
number of moles = mass/ molar mass
Number of moles = 0.24 g/ 100.1 g/mol
Number of moles = 0.002 mol
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.
1 mole of CaCO₃ contain 3 moles of oxygen atom.
0.002 mol × 3 = 0.006 moles of oxygen atoms.
Number of oxygen atoms:
1 mole = 6.022 × 10²³ number of oxygen atoms
0.006 mol × 6.022 × 10²³ f oxygen atoms / 1 mol
0.036 × 10²³ oxygen atoms
Answer:
a vector with speed and strenght
Explanation:
What is Solidification?
The process by which liquid metals turn into tiny solid particles at the phase boundary temperature is known as solidification or freezing.
How does solidification occur?
Solidification occurs when a liquid's temperature is reduced below its freezing point. Although the freezing point and melting point of the majority of materials are the same temperatures, this is not always the case and the words freezing point and melting point are not synonymous.
When a liquid turns into a solid, the process is always exothermic, which means heat is released.
Based on casting technology, solidification is a key component of several other processes, such as crystal growth, welding, surface alloying, the manufacturing of ingots, and the purification and refinement of raw materials. It is a crucial step in the technology of metals, as well as ceramics and polymers.
