Lithium 6 would have 6 valence electrons in the outer orbital, while lithium 7 would have 7 in the outer orbital.
Answer:
<h2>18 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have
We have the final answer as
<h3>18 g/mL</h3>
Hope this helps you
Answer: 2.408×10^24 atoms
Explanation:
Applying the formula
No. moles= (no. Of atoms)/Avogadro's number
4 = n/6.02×10^23
no. of atoms= 2.408×10^24 atoms
Explanation:
We're using the chemical equation:
4P + 5O2 → P4O10
First convert grams of product to moles:
75g P4O10 x (1mol / 284 g) = 0.264 mol P4O10
Using the mole ratios, convert moles of product into moles of reactant needed:
0.264 mol P4O10 x (5 mol P / 1 mol P4O10) = 1.32 mol O2
