Explanation:
This is correct!
Ions that exist in both the reactant and product side of the equation are referred to as spectator ions. Overall, they do not partake in the reaction. If they are present on both sides of the equation, you can cancel them out.
An example is;
Na+(aq) + Cl−(aq) + Ag+(aq) + NO3−(aq) → Na+(aq) + NO3−(aq) + AgCl(s)
The ions; Na+, NO3−(aq) would be cancelled out to give;
Cl−(aq) + Ag+(aq) → AgCl(s)

Explanation:
Your answer is A....They have the same number of protons and neutrons, but a different number of electrons. They have the same number of protons and electrons, but a different number of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers.....
Most likely the carbonic acid im guessing H2CO3 undergoes thermal decomposition
H2CO3 ===> H2O + CO2
hope that helps
Answer:
h. 37.5 cm³
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have different values of V and T:
<em>(V₁T₂) = (V₂T₁). </em>
V₁ = 50.0 cm³, T₁ = -73°C + 273 = 200 K,
V₂ = ??? cm³, T₂ = -123°C + 273 = 150 K.
∴ V₂ = (V₁T₂)/(T₁) = (50.0 cm³)(150 K)/(200 K) = 37.5 cm³.
- <em>So, the right choice is: </em><em>h. 37.5 cm³.</em>
