Answer:
Explanation:
moles of acetic acid = 500 x 10⁻³ x .1 M
= 5 X 10⁻³ M
.005 M
Moles of NaOH = .1 M
Moles of sodium acetate formed = .005 M
Moles of NaOH left = .095 M
pOH = 4.8 + log .005 / .095
= 4.8 -1.27875
= 3.52125
pH = 14 - 3.52125
= 10.48
% Composition = ?
no atom in 2 g of styrene =?
molar mass of strene =104.15
% composition of c= 12/13.008 =.922*100=92.2
% composition of h =1.008/13.008=0.0774*100= 7.74
no gram atom=mass in kg /molar mass=2/104.15 =0.01920 mol
no of gram atom * avogadro's number = 0.0192*6.02 *10( exponent 23) =1.15584
When u give supply to a coil then a current will be passed through it .
<span>naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. and </span>
<span>by lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced</span>
When the temperature increases, warms, or heats up the molecules become excited. Their movement becomes faster and they tend to move far apart from other molecules.
