The reaction between HCl and NaHCO3 will be;
HCl + NaHCO3 = NaCl + CO2 + H2O
The relative formula mass of NaHCO3 is 84 g/mol
Moles of NaHCO3 in 2 g will be; 2/84 =0.0238 moles
The mole ratio of HCl and NaHCO3 is 1;1
Thus, the number of moles of HCl is 0.0238 moles
The volume of HCl will be;
= 0.0238 moles/0.2
= 0.119 liters or 119 cm³
Its tetrahedral since there's four chlorine molecules around carbon
Answer:
0.19M
Explanation:
2A → A2
Rate constant = 0.0265 M–1min–1
Initial concentration = 2.00 M
Final Concentration = ?
time, t = 180min
The formular relating the parameters is given as;
1 / [A] = kt + 1 / [A]o
1 / [A] = 0.0265 * 180 + (1 / 2)
1 / [A] = 4.77 + 0.5
[A] = 1 / 5.27 = 0.19M
Given the speed, you will travel 195km in 3 hours.
65 x 3 = 195
Answer:
Decomposition
Explanation:
single displacement is ab+c=ac+b
synthesis is a+b=ab
decomp is ab=a+b
douple displacement is ab+cd=ac+bd
combustion involves co2.
