Answer:
NaOH is limiting
Explanation:
Hcl + NaOH ------------ Nacl + H2O
Given 7.81g 5.24g
mol weights 1+35.5 23+16+1
36.5 40
No of Moles 7.81/36.5 5.24/40
0.2139 0.131
No of moles = weight/ molecular weight
No of moles of NaOH is lower so it is limiting as according to equation one mole of Hcl requires mole of NaOH so equal number of moles are required. NaOH is 0.131 which is far lower than 0.2139

It would work better to add the sugar right after the coffee has brewed, while it is still hot!!
Hope I Helped!!!
<span>Since at STP, the molar volume is 22.4 L, all of these containers have one mole of gas. The one with the highest atomic or molecular weight is the heaviest: :
A) H2 - 2 g/mole
B) N2 - 28 g/mole
C) O2 - 32 g/mole
D) CO2 - 44 g/mole
E)He - 4 g/mole
Ans will CO2 - 44 g/mole with the highest atomic or molecular weight is the heaviest.</span>
The moles of butane gas and oxygen gas reacted if 2.50 moles of H2O is produced is calculated as below
the equation for reaction
2C4H10 +13 O2 = 8CO2 +10 H2O
the moles of butane (C4H10) reacted calculation
by use of mole ratio between C4H10: H2O which is 2 : 10 the moles of C4H10= 2.50 x2/10 = 0.5 moles of C4H10 reacted
The moles of O2 reacted calculation
by use of mole ratio between O2 : H2O which is 13:10 the moles of O2
= 2.50 x 13/10= 3.25 moles of O2 reacted
Copper(ii)nitrate is the name
