Answer:
O.5 h
Explanation:
If it can travel 1224 kilometers an hour then traveling 612 would take half an hour to do.
When atoms react they form a chemical bond which is defined as the force of attraction that holds atoms together. It can be covalent bonding, ionic bonding or metallic type of bonding. These bonds are what atoms in a compound hold together.
Answer:
The emission spectrum is formed when the electrons of a particular atom absorb energy and are excited (in this case by heating), reaching higher energy levels.
You can see it for example with an experiment where we light alcohol mixed with banana chips (it has potassium). The burning alcohol emits heat that makes potassium atoms excite and these in turn emit something red, orange light. If we add for example boric acid you see a green light.
Explanation:
The number of sulfate ions : 2.2 x 10²³
<h3>Further explanation</h3>
Reaction
Al₂(SO₄)₃⇒2Al³⁺+3SO₄²⁻
mol Al₂(SO₄)₃(MW=342,15 g/mol) :
mol of sulfate ions (SO₄²⁻)
1 mol = 6.02 x 10²³ particles (ions, molecules, atoms), so for 0.366 mol :
