Answer:
3.45 moles Li contains 2.08
×
10
(to the power of)24 atoms
.
Explanation:
The relationship between atoms and moles is:
1 mole atoms
=
6.022
×
10
(to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022
×
10
(to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45
mol Li

10
(to the power of)23 atoms Li/
1
mol Li
=
2.08

Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>
Hope this helps you
Answer:
C
Explanation:
You would be correct in guessing C as in a chemical formula symbol of each element is stated.
Like Salt is Sodium Chloride, and its chemical formula is NaCl (Na=sodium, Cl= chloride)
Physical change because it's only changing the shape of the gold.
