Answer:

<h2>The atom having 5 proton (B) atom when a boron become cations , the numbers of protons is still 5 no mater how many electrons are lost . therefor , the three different atomic cations that all have 5 protons: B<u>+</u><u>,</u><u>B2</u><u>+</u><u> </u><u>and</u><u> </u><u>B3</u><u>+</u></h2>

5.40 g B determine the number of atoms
sdas [7]
Atomic mass Boron ( B ) = 10.811 u.m.a

10.811 g -------------- 6.02x10²³ atoms
5.40 g ----------------- ?? atoms

5.40 x ( 6.02x10²³) / 10.811 =

3.0069x10²³ atoms

Calculate the standard molar enthalpy for the complete combustion of liquid ethanol (c2h5oh) using the standard enthalpies of fo
olga2289 [7]
Answer : To calculate the standard molar enthalpy of complete combustion of liquid ethanol can be done by using the formula given below;

C_{2}  H_{5}OH + 3O_{2} ----\ \textgreater \   2CO_{2}  + 3 H_{2}O

Now, the enthalpies of the elements in their standard state is zero always. 

So the H_{reaction} =  H_{products}  - H_{reactants}

Here we can avoid the heat of enthalpy of oxygen,carbon dioxide and water as they exists in their standard states.

So the H_{reaction} = H_{ C_{2}H_{5}OH}
