Energy production
Thus most industries in working burn oxygen as fuel. Examples are steel production and production of chemicals
Answer:
pH = 6.5
Explanation:
pH is the negative log of the hydronium concentration, [H⁺]. Since we are given the concentration, we can just plug it in the following equation:
pH = -log[H⁺] = -log[3.5 x 10^-7 M] = 6.5
Answer:
85.384 atm or 64608.13086 mmHg
Explanation:
PV= NRT
P= NRT/V
n= mols
R= gas constant (i used .0821 for atm)
T= Temp in Kelvins (Celsius degrees + 273)
V= in L
(65molsx480kx.0821)/30L
Volume of solute = 25 mL
Volume of solvent = 150 mL
% = ( volume of solute / volume of solvent ) x 100
% = ( 25 / 150 ) x 100
% = 0,166 x 100
= 16.6 % v/v
hope this helps!
Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.
