What is the balanced form fir Na(s) + ao2(g) = Na2O(s)​

Chemistry
1 answer:
Dima020 [189]3 years ago
6 0

Answer:

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Explanation:

Chemical equation:

Na + O₂ → Na₂O

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.

Coefficient with reactant and products:

Na   4

O₂     1

Na₂O  2

Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.

Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.

When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.

Calculate the freezing point of the solution containing 0.105 m k2s. calculate the boiling point of the solution above. -g
Licemer1 [7]
Quantity of K2S m = 0.105 m 
Number of ions i = 2(K) + 1(S) = 3
 Freezing point depression constant of water Kf = 1.86 
delta T = i x m x Kf = 3 x 0.105 x 1.86 = 0.586
 Freezing point = 0 - 0.586 = 0.586 C
 Boiling point constant of water Kb = 0.512
 delta T = i x m x Kb = 3 x 0.105 x 0.512 = 0.161
 Boiling point = 100 + 0.161 = 100.161 C

Why does a higher concentration make a reaction faster?
myrzilka [38]
Option B is correct, 
                             With increase in concentration the density of reactants increases and the system becomes more crowded, the greater the reactants will come in contact with each other and collisions occur. If collision is in proper orientation and has optimum energy then its fruitful and yields product. So, the greater the number of reactants, the greater will be the chances of collision and the greater will be the production of products per unit time and hence, greater is the rate of reaction.

How many moles are in 4.99x1032 molecules of H2o
bogdanovich [222]

Answer:

n≈8,29×10⁸ moles

Explanation:

Nᴀ=6.02×10²³ (constant)

n=N/Nᴀ=

=  \frac{ {4.99 \times 10}^{32} }{6.02 \times 10 ^{23} }  = 828903654

≈8,29×10⁸ moles
