Answer:
The more acidic the solution the faster it rusts. More Na = more rust
Explanation:
Answer:
r = 0.0018 molxL⁻¹xs⁻¹
t = 472.22 s
Explanation:
The rate of the reaction is given by:
Where <em>r</em> is the rate, <em>k</em> is the rate constant, <em>[A]</em> is the initial concentration of the reactant and <em>n</em> is the order of the reaction. So, for this problem:
r = 0.0018x[1.70]⁰
r = 0.0018 molxL⁻¹xs⁻¹
The rate is also the variation of the concentration divided by the time. So, for the half-life, the concentration will be decreased by half and will be 0.85 mol/L. So the variation will be 1.70 - 0.85 = 0.85 mol/L. So:
0.0018 = 0.85/t
t = 0.85/0.0018
t = 472.22 s
Answer:
glucose molecules that our cells need from is plants
The balanced chemical reaction is written as:
3HCl + Al(OH)3 = AlCl3 + 3H2O
We calculate as follows:
1.51 g Al(OH)3 ( 1 mol / 78.01 g ) ( 3 mol HCl / 1 mol Al(OH)3 ) ( 1 L / 0.100 mol HCl ) = 0.581 L of 0.100 M HCl solution is needed
Hope this answers the question. Have a nice day.
