Answer:
m AgCl = 28.395 g
Explanation:
- AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
∴ [AgNO3] = 0.156 mol/L
∴ V = 1.27L
⇒ mol AgNO3 = 0.156 mol/L * 1.27 L = 0.19812 mol AgNO3
mass AgCL:
⇒ m AgCl = 0.19812 mol AgNO3 * mol AgCl/molAgNO3 * 143.32gAgCl/molAgCl
⇒ m AgCl = 28.395 g
Answer:
A chemical bond is formed and energy is absorbed I do believe
Explanation:
Answer:
1.51986 atm
Explanation:
You can also search "154 kPa to atm" and a converter will appear
Answer: A thermal conductor is a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself.
Explanation:
Mass %abundance # of atoms (pick 1000 sample)
68.9257 60.4% 604
70.9249 39.6% 396
*39.6* ( i got this by subtracting 100 as most percentage is out of 100)
*# of atoms* ( i just moved it one decimal place, then i am going to make the sample out of 1000, to get the decimal place)
Formula= total mass/ total #atoms
x= (68.9257u* 604) + (70. 9249*396)/ 1000
x- 69717. 3832/ 1000
x= 69.717amu or 69.72 amu
if you look on the periodic table the closet element with that mass is gallium ( amu is 69.72)
