Reactivity of Group 1 and 2 elements increases as you go down the periodic table. So sodium is more reactive than lithium. Sodium will react with oxygen forming Na2O (sodium oxide). Lithium forms lithium oxide (Li2O).

Mazyrski [523]
The gram-formula mass of Sm is 150.36 u, and the gram-formula mass of O is 15.999 u, so the gram-formula mass of SmO is about 150.36+15.999 = 160.36 g/mol.

So, there are about (9.30 * 10^-3)(160.36)=1.49 grams

Show the calculation of the energy involved in condensation of 150 grams of steam at 100oC if the Heat of Vaporization for water
vaieri [72.5K]

Answer : The energy involved in condensation is, 339 kJ

Explanation :

Formula used :

q=m\times L

where,

q = heat required = ?

L = latent heat of vaporization of water = 2.26kJ/g

m = mass of water = 150 g

Now put all the given values in the above formula, we get:

q=(150g)\times (2.26kJ/g)

q=339kJ

Therefore, the energy involved in condensation is, 339 kJ

Brrunno [24]

Answer:

The volume that this same amount of air will occupy in his lungs when he reaches a depth of 124 m is - 0.27 L.

Explanation:

Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 3.6 L  

V₂ = ?

P₁ = 1.0 atm

P₂ = 13.3 atm

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{1.0\ atm}\times {3.6\ L}={13.3\ atm}\times {V_2}

{V_2}=\frac{{1.0}\times {3.6}}{13.3}\ L

{V_2}=0.27\ L

<u>The volume that this same amount of air will occupy in his lungs when he reaches a depth of 124 m is - 0.27 L.</u>
