Answer:
The answer to your question is 471.2 g
Explanation:
Data
moles of Cu(HCO₃)₂ = 2.54
mass of Cu(HCO₃)₂ = ?
Process
1.- Calculate the molar mass of Copper (II) bicarbonate
Cu(HCO₃)₂ = (1 x 63.5) + (2 x 1) + (2 x 12) + (6 x 16)
= 63.5 + 2 + 24 + 96
= 185.5 g
2.- Use proportions and cross multiplication to find the mass
185.5 g of Cu(HCO₃)₂ ------------- 1 mol
x ------------- 2.54 mol
x = (2.54 x 185.5) / 1
x = 471.2 g
Answer:
energy that is transmitted in the form of electromagnetic waves.
Explanation:
Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
Yeah, a lot faster than sound.
Answer:3Li+YbCl3=Yb +3LiCl
Explanation:as there are three cl in the first one so to balance them we will put 3before LiCl in order to make Cl balanced now there are 3 Li also so put before Li 3 making it also balanced Yb is balanced already
