First calculate the moles of CsOH.
moles CsOH = 0.217 M * 0.005 L = 0.001085 mol
We need 1 mole of HI per 1 mole of CsOH, therefore the
moles of HI needed is:
moles HI = 0.001085 mol
The volume required is therefore:
Volume = 0.001085 mol / 0.550 M
<span>Volume = 1.97x10^-3 L = 1.97 mL</span>
Hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water. Sodium chloride is made up of Na+ cations from the base (NaOH) and Cl- anions from the acid (HCl). HCl+NaOH→H2O+NaCl.
Answer:
Explanation:
We can use oxidation numbers to decide which substance is reduced.
The oxidation number of Na changes from 0 in Na to +1 in Na⁺.
The oxidation number of H changes from +1 in H₂O to 0 in H₂.
1 and 4 are wrong because H₂ and Na⁺ are products.
2. is wrong because there is no H⁺ to be oxidized or reduced.
The answer is C. X: Benefits
Y: Risks
Answer:
17 mc/L
Explanation:
We habe heat that is taken by the ice for it to melt to be equal to the heat given by water.
ML = mc(290K - 273K)
ML = mc 17
Then we divide through by L
M = 17 mc/L
Please note that 273k as we have used in thIs solution is the temperature at which we can have water to freeze
Therefore the minimum mass of required ice = 17 mc/L
