Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.
Explanation:
I think it would have 10 neutrons. Hope this helps :)
10 elements compose the bulk of rock forming minerals
Answer:
Explanation:
If an antacid has sodium hydrogen carbonate/Calcium carbonate, it reacts with HCl as shown
NaHCO₃+ HCl → NaCl + CO₂+ H₂O
Antacid acid salt gas water
CaCO₃+ 2HCl → CaCl₂+ CO₂+ H₂O
Antacid acid salt gas water
The formation of gas CO₂ is shown by brisk effervescence when the antacid (sodium hydrogen carbonate/calcium carbonate) reacts with HCl (acid). So CO₂ is the additional product formed and its formation is supported by observation of brisk effervescence as HCl is added to the antacid.
Hi, thank you for posting your question here at Brainly.
The acid dissociation constant, Ka, is an equilibrium constant that measure the strength of an acid. It is a ratio of the concentration of the products (salt and water) and the reactants (acid). The higher the Ka, the more tendency it is to favor the product side, which means more tendency to donate H+ ions. This is exactly the definition of a strong acid (high H+ ionized).
Thus, the answer is letter D.
