Match the reaction on the right with the corresponding reaction on the left by writing the correct, matching number in the space

provided. solid sodium + chlorine gas → solid sodium chloride solid sodium + liquid water → aqueous sodium hydroxide + hydrogen gas 2H2(g) + O2(g) → 2H2O(g) 2H2O2(aq) → O2(g) + 2H2O(l) 1) aqueous hydrogen peroxide → oxygen gas + liquid water 2) 2Na(s) + Cl2(g) → 2NaCl(s) 3) hydrogen gas + oxygen gas → water gas 4) 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Explanation:

The first given equation in words is as follows.

solid sodium + chlorine gas \rightarrow solid sodium chloride

The chemical equation for this reaction will be written as follows.

        Na(s) + Cl(g) \rightarrow NaCl (s)

The second given equation in words is as follows.

solid sodium + liquid water \rightarrow aqueous sodium hydroxide + hydrogen gas

The chemical equation for this reaction will be written as follows.

    Na(s) + H_{2}O(l) \rightarrow NaOH(aq) + H_{2}

The third given equation is as follows.

    2H_{2}(g) + O_{2}(g) \rightarrow 2H_{2}O(g)

This equation can be written in words as follows.

hydrogen gas + oxygen gas \rightarrow water gas

The fourth given equation is as follows.

     2H_{2}O_{2}(aq) \rightarrow O_{2}(g) + 2H_{2}O(l)

This equation can be written in words as follows.

aqueous hydrogen peroxide \rightarrow oxygen gas + liquid water

Thus, match the given data as follows.

  • solid sodium + chlorine gas \rightarrow solid sodium chloride - (2).  2Na(s) + Cl_{2}(g) \rightarrow 2NaCl (s)
  • solid sodium + liquid water \rightarrow aqueous sodium hydroxide + hydrogen gas - (4).  2Na(s) + 2H_{2}O(l) \rightarrow 2NaOH(aq) + H_{2}
  • 2H_{2}(g) + O_{2}(g) \rightarrow 2H_{2}O(g) - (3). hydrogen gas + oxygen gas \rightarrow water gas.
  • 2H_{2}O_{2}(aq) \rightarrow O_{2}(g) + 2H_{2}O(l) - (1). aqueous hydrogen peroxide \rightarrow oxygen gas + liquid water

Chem help<br>calculate the wavelength of an electromagnetic wave with a frequency of (in pic)​
olchik [2.2K]

we have,

wavelenght=c/f

where c= 3×10^8 m/s

f=6.3×10^12 s^-1

so wavelength=(3×10^8)/(6.3×10^12)

=0.476×10^-4 m
