1.8 mol HCl and 3.3 mol NaOH react accord- ing to the equation HCl + NaOH −→ NaCl + H2O . Calculate the amount in moles of NaCl
ollegr [7]

Answer:

1.8 moles of NaCl must be produced.

Explanation:

Based on the reaction:

HCl + NaOH → NaCl + H2O

<em>1 mol of HCl reacts with 1 mol of NaOH to produce 1mol of NaCl</em>

<em />

To solve this question we must find, as first, the <em>limiting reactant:</em>

<em />

1.8 moles of HCl will need 1.8 moles of NaOH for a complete reaction (Ratio of reaction 1:1). As there are 3.3 moles of NaOH,

<em>HCl is limiting reactant</em>

<em />

When the 1.8 moles of HCl react completely,

1.8 moles of NaCl must be produced because 1 mole of HCl produce 1 mole of NaCl

Answer:

Precipitation

Explanation:

In the water cycle, water experiences different phase changes from one state to another in nature.

The cycling affords water to in solid, liquid and the vapor form.

From the cycle show, W represents precipitation.

  • During precipitation, water in the atmosphere begins to fall.
  • U is evaporation
  • X is transpiration.
  • V is the condensation.

In a titration, 25.0 mL of 0.500 M KHP is titrated to the equivalence point with NaOH. The final solution volume is 53.5 mL. Wha
Lena [83]
M1v1=m2v2 
m2=(m1v1)/v2 
Where m is the molarities and v is the volumes
<span>m2=(25.0*0.500)/53.5
m2=12.5/53.5
m2=0.2336
by rounding off:
m2=0.234 M
so the answer is C: 0.234 M</span>
