The reaction between calcium carbonate and hydrochloric acid can be expressed through the chemical reaction,
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
The molecular weight of calcium carbonate is 100 g/mol while that of hydrochloric acid is 36.45. The equation above depicts that 100 g of calcium carbonate can be dissolved in 72.9 g of hydrochloric acid.
x = (4 g HCl)(100 g CaCO3 / 72.9 HCl)
x = 5.49 g
Answer: 5.49 g
Carbon dioxide (CO2)
Argon (Ar)
Hydrogen (H)
Helium (He)
Earth isn’t likely going to be running out of gold for around 50-100 years
Answer:
Due to how big the glacier is you would need more heat to melt it and since the ice cube is smaller a small amount of heat would melt it
