You should classify it as co2 solid as CO2(s) and that small left comes to the bottom right hand side and dry ice is a form of liquid carbon dioxide so u should write it as CO2(l) and that L comes to the bottom right hand sise
The chemical reaction would most likely be written as follows:
A + B = AB
We cannot simply use the usual method of converting grams to moles since we do not have any idea on what are the identities of A and B. The only method we could use is to use the law of conservation of mass where mass inflow in a process should be equal to the mass out in the process. The total inflow of mass would be the mass of A and B and the outflow would be the product AB.
mass of A + mass of B = mass of AB
10.0 g A + 10.0 g B = mass of AB
mass of AB = 20.0 g
Answer:
if it is espresso(1 shot), the coffee content to be considered is: (77/44)*(10/3)= 5.833= 0.005833 grams

Answer:
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years
Explanation:
Answer:
Option 5.
Equal amounts of hydroxide and hydronium ions
Explanation:
2H₂O ⇄ H₃O⁺ + OH⁻ Kw: 1×10⁻¹⁴
Neutral solution has pH = 7
So, [H₃O⁺] = [OH⁻]
In solutions of only pure water:
[H₃O⁺] = 1×10⁻⁷ M
[OH⁻] = 1×10⁻⁷ M
Kw = [H₃O⁺] . [OH⁻] → 1×10⁻⁷ . 1×10⁻⁷ = 1×10⁻¹⁴
