Left side metals right side non metals. arrganged in groups (columns) and periods (rows), each group tells you amount of valence electrons
Answer:
i think use water displacement with just one 10c
Explanation:
Answer:
Mole Fraction = 0.059
Explanation:
To find the mole fraction, you need to (1) convert grams H₂SO₄ and H₂O to moles (via molar mass) and then (2) calculate the mole fraction.
(Step 1)
Molar Mass (H₂SO₄): 98 g/mol
34 grams H₂SO₄ 1 mole
-------------------------- x ------------------- = 0.347 moles H₂SO₄
98 grams
Molar Mass (H₂O): 18 g/mol
100 grams H₂O 1 mole
------------------------- x -------------------- = 5.56 moles H₂O
18 grams
(Step 2)
moles solute
Mole Fraction = -------------------------------------------------
moles solute + moles solvent
0.347 moles H₂SO₄
Mole Fraction = -----------------------------------------------------------
0.347 moles H₂SO₄ + 5.56 moles H₂O
Mole Fraction = 0.059
Answer:
yep.. I am wide awake here.
Answer: single replacement
Explanation: metals higher than hydrogen in the activity series will always displaced or replace hydrogen in a solution. Pb is higher than hydrogen in the activity series, so it will displaces or replace hydrogen in a solution
