What might two Group 16 non metals likely form?

1 answer:

7 0

When the compound is composed of two non-metals, the the bond that joins them together is called covlent bond. Otherwise, when the compound is composed of a metal and a non-metal then the bond existing between them is called ionic bond. Answer then to this problem is A. covalent bond

Hii pls help me!! even if u know how to do one, it's okk anything helps

tensa zangetsu [6.8K]

Explanation:

a) HNO2(aq) = HNO3(aq) + H2O(l) +NO(g)

b) SoCl2 (l) + H2O (l) = So2(g) + 2HCl(aq)

c) CH4 (g) + 2O2(g) = Co2 (g) + 2H2O(g)

d) 3CuO(s) + 2NH3 (g) = 3Cu(s) + 3H2O (l) + N2(g)

Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 2.7 g of ethane is m

Bond [772]

Answer:

$m_{H_2O}=4.86gH_2O$

Explanation:

Hello,

In this case, the described chemical reaction is:

$C_2H_6+\frac{7}{2} O_2\rightarrow 2CO_2+3H_2O$

Thus, for the given reacting masses, we must identify the limiting reactant for us to determine the maximum mass of water that could be produced, therefore, we proceed to compute the available moles of ethane:

$n_{C_2H_6}=2.7gC_2H_6*\frac{1molC_2H_6}{30gC_2H_6} =0.09molC_2H_6$

Next, we compute the moles of ethane consumed by 13.0 grams of oxygen by using the 1:7/2 molar ratio between them:

$n_{C_2H_6}^{consumed\ by \ O_2}=13.0gO_2*\frac{1molO_2}{32gO_2}*\frac{1molC_2H_6}{\frac{7}{2} molO_2}=0.116molC_2H_6$

Thus, we notice there are less available moles of ethane, for that reason, it is the limiting reactant, thereby, the maximum amount of water is computed by considering the 1:3 molar ratio between ethane and water:

$m_{H_2O}=0.09molC_2H_6*\frac{3molH_2O}{1molC_2H_6} *\frac{18gH_2O}{1molH_2O} \\\\m_{H_2O}=4.86gH_2O$

Best regards.

Balanced:
1. Na2O + H2O ---> 2NaOH
2. K2O + H2O ---> 2KOH
3. MgO + H2O ---> Mg(OH)2
4. CaO + H2O ---> Ca(OH)2
5. SO2 + H2O ⇄ H2SO3
6. SO3 + H2O ---> H2SO4
All except by 2 were balanced.
