Answer:
The highly unstable pure sodium or potassium wants to lose an electron and this splits the water atom, producing a negatively charged hydroxide ion and hydrogen and forming an explosive gas that ignites.
Explanation:
Balance Chemical Equation is as follow,
<span> Cu + 2 AgNO</span>₃ → 2 Ag + Cu(NO₃)₂
According to Balance Equation,
2 Moles of Ag is produced by reacting = 1 Mole of Cu
So,
0.854 Moles of Ag will be produced by reacting = X Moles of Cu
Solving for X,
X = (0.854 mol × 1 mol) ÷ 2 mol
X = 0.427 Moles of Cu
Result:
0.854 Moles of Ag are produced by reacting 0.427 Moles of Cu.
Answer:
2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation.
Explanation:
carbohydrate,fat,protein, vitamin, mineral, water
This is the order of activity in decreasing way for the mentioned metals
Mn>Zn>Cr>Fe>Cd>Co>Ni>Pb
Fe is in between Cr and Cd, it is more active than Cd and less active than Cr, so it will displace Cd but not Cr.
Answer:Fe (it will displace Cd, but not Cr)
