D. A constant pressure calorimeter would be used because an increase in heat causes an increase in pressure.
<span>1.190x10^-1 m/l
First, calculate how many moles of NaOH was used.
0.03430 l * 8.670x10^-2 mol/l = 2.97381x10^-3 mol
So we used 2.97381x10^-3 moles of NaOH, which means we had 2.97381x10^-3 moles of HCl in the original sample. So the molarity of the original sample is the number of moles divided by the volume.
2.97381x10^-3 mol / 0.02500 = 0.1189524 m
Rounding to 4 significant figures gives 0.1190 or 1.190x10^-1 m</span>
1. Metallic bond is a type of chemical bond.
2. Metallic bond is formed between electrons and positively charged metal ions.
3. Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
4. Metallic bond increace electrical and thermal conductivity.
5. Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
The second stage of photosynthesis also called Calvin stage produces glucose
Answer: M = 22/ (i x28.948)
Explanation:
Pi = osmotic pressure = 22atm
T = Temperature = 353K
M = Molarity = ?
R = gas constant = 0.082atm.L/mol/K
i = van’t Hoff factor
Pi = iMRT
M= Pi /(iRT) = 22 / ( i x 0.082 x 353)
M = 22/ (i x28.948)
