Answer:
NaHCO3 + HCl ——-> NaCl + H2O + CO2
Explanation:
A neutralization reaction is a chemical reaction between an alkali and an acid to give salt and water as the product.
In the case of carbonates and bicarbonates, an additional product is added. This additional product is carbon iv oxide.
Hence a neutralization reaction involving an acid and a carbonate or bicarbonate would yield water, carbon iv oxide and a salt as the product.
When brioschi reacts with hydrochloric acid, the products are sodium chloride, water and carbon iv oxide.
The equation of the reaction is shown below:
NaHCO3 + HCl ——> NaCl + H2O + CO2
8.1moles
Explanation:
Given parameters:
Mass of water to be decomposed = 29.2g
Unknown:
Number of moles of oxygen.
Solution:
To solve this problem, we first write the balanced reaction equation :
2H₂O → 2H₂ + O₂
Now convert the given mass of the water to number of moles;
Number of moles of water = 
Molar mass of water = 2(1) + 16 = 18g/mol
Number of moles of water = 
= 16.2moles
From the balanced reaction equation:
2 moles of water produced 1 mole of oxygen gas;
16.2 mole of water will produce 
= 8.1moles of oxygen gas

A) -0.5(9.8)*t^2 = -25(t-2) - 0.5(9.8)(t-2)^2
-4.9t^2 = -25t + 50 - 4.9(t^2-4t+4)
0 = -25t+50+19.6t - 19.6
5.4t = 30.4
t = 5.62962963 s
b) h = -4.9(5.62962963)^2
h = -155.2943759

Stratus clouds reside below the 6,000ft range.
Altocumulus clouds reside in the 6,500-20,000ft range.
Cirrus clouds reside above the 20,000ft range.
Ordered from highest to lowest, the sequence of clouds will be:
Cirrus
