Many homeowners treat their lawns with CaCO3(s) to reduce the acidity of the soil. Write a net ionic equation for the reaction o
Agata [3.3K]

The reaction of acid, assuming HCl and calcium carbonate always produces a gas. The reaction is as follows:
2 HCl + CaCO3 --> CaCl2 + H2CO3 
H2CO3, carbonic acid, is a weak acid that is unstable in water solutions at high concentrations. As such, it decomposes: 
H2CO3 --> H2O + CO2 
Then, 
2 HCl + CaCO3 --> CaCl2 + H2O + CO2 
The total ionic equation looks as follows: 
2H+(aq) + 2 Cl-(aq) + CaCO3(s) --> Ca+2(aq) + 2 Cl-(aq) + H2O(l) + CO2(g) 
Clearly, Cl- is a spectator ion as it is unchanged in the reaction. The net ionic reaction looks as follows: 
2 H+(aq) + CaCO3(s) --> Ca+2(aq) + H2O(l) + CO2(g)

Ipatiy [6.2K]

Therac-25, AECL was able to reduce costs by replacing hardware safety features with software controls.

the Therac-25 was a laptop-controlled radiation therapy machine produced by Atomic energy state Canada limited in 1982 after the Therac-6 and Therac-20 units. It was involved in at least six accidents between 1985 and 1987, in which patients were given massive overdoses state radiation.

The Therac-25 machine was a state-of-the-art linear accelerator developed by using the company Atomic strength Canada restricted (AECL) and a French company CGR to provide radiation treatment to cancer sufferers. The Therac-25 become the most computerized and complicated radiation therapy device state its time.
