Answer:
C) solid, liquid, gas
Explanation:
Which grouping shows a decrease in Intermolecular
Forces of Attraction?
A) gas, liquid, solid B) liquid, solid, gas
C) solid, liquid, gas D) solid, gas, liquid
the further the particles are from each other, the less the intermolecular attraction they are farthest in a gas, then a liquid, and closest in a solid
Amplitude is the awnser glad I could help you
<h2>The required "options are (II), (III), and (IV)".</h2>
Explanation:
Postulates of Dalton's atomic theory which are scientifically accepted are:
- Atoms are indestructible.
- Compounds are combinations of different atoms.
- A chemical reaction changes the way atoms are grouped together.
Postulates of Dalton's atomic theory which are not accepted scientifically are:
- All atoms of the same elements are identical.
The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
A) Selenium - is apart of Sulfur family
Answer:
The answer to your question is: 0.1 M
Explanation:
data
Volume of AgNO3 = 20.00 ml
1000 ml -------------- 1 l
20 ml --------------- x
x = 20x 1 /1000 = 0.02
AgCl = 0.2867 g
MW of AgCl = 35.45 + 107.9 = 143.35 g
143.35 g -------------- 1 mol
0.2867 g ------------- x
x = 0.2867 x 1 / 143.35 = 0.002 moles of AgCl
From the balance reaction we see that the proportion of AgNO3 to AgCl is 1:1, then
1 mol of AgNO3 -------------------- 1 mol of AgCL
x --------------------- 0.002 moles of AgCl
x = 0.002 moles of AgNO3
This moles of AgNO3 are in 20 ml or 0.02 liters
So, Molarity = # moles/liter
Molarity = 0.002 moles/ 0.02 = 0.1 M
