Temperature means, in this context, movement.
Condensation can be explained by the reduction of temperature of the system. This effect make possible the cohesion forces increases. In other words, the result is coalescence by attractive forces.
Answer:
The answer to your question is 2.3 g
Explanation:
Data
Molecule = NaOH
grams of Na in 4 g of NaOH
Process
1.- Calculate the molecular mass of NaOH
molecular mass = (1 x 23) + (1 x 16) + (1 x 1)
= 23 + 16 + 1
= 40 g
2.- Calculate the atomic mass of sodium
atomic mass = 23 g
3.- Use proportions to solve this problem
40 g of NaOH ---------------- 4 g of NaOH
23 g of Na ---------------- x
x = (4 x 23) / 40
x = 2.3 g
Answer:
Explanation:
OK this is simple
i'll try to do the unanswered question
CaCl2
In the table
You look for calcium,Ca you fill 1
THen for Chloride=2
i hope you've understood
3.01 x 10^23 molecules (1 mole/6.203 x 10^23 molecules) = 0.500 moles<span>
