Answer:
im pretty sure its b. sand and iron
ik that magnetism easily separates iron
Answer:
600mL
Explanation:
Molarity of a solution (M) = number of moles (n) ÷ volume (V)
number of moles = mass/molar mass
Molar mass of NaOH = 23 + 16 + 1
= 40g/mol
mole = 30/40
n of NaOH = 0.75mol
Using Molarity = n/V
V = number of moles ÷ molarity
V = 0.75 ÷ 1.25
V = 0.6L
In milliliters (mL), the volume of NaOH will be 0.6 × 1000
= 600mL
It's C: It flows through Venezuela
C. MnO₄ + 4C₂H₂O₄ → Mn + 8CO₂ + 4H₂O
