First, we write the reaction equation:
2KI + PbNO₃ → K₂NO₃ + PbI₂
The molar ratio of KI to PbNO₃ is 2 : 1
Moles of PbNO₃ present:
Moles = concentration (M) x volume (dm³)
= 0.194 x 0.195
= 0.038
Moles of KI required = 2 x 0.038 = 0.076 moles
concentration = moles / volume
volume = moles / concentration
= 0.076 / 0.2
= 0.38 L = 380 ml
The food chain always begins with a sun without it there would be no food chain... hope this helped!
Answer:
oxidation:Ti to Ti Reduction:O2 toO2
Explanation:
<em>oxidation loses electron while Reduction gains electron</em>
<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>
➪Methane (CH4) is oxidized with molecu- lar oxygen (O2) to carbon dioxide (CO2).
Your answer is False I think
