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

How many atoms are present in a sample of Potassium (K) weighing 33.49g?
madam [21]

Answer:

5.158 × 10²³ atoms K

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Explanation:

<u>Step 1: Define</u>

33.49 g K

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of K - 39.10 g/mol

<u>Step 3: Convert</u>

<u />33.49 \ g \ K(\frac{1 \ mol \ K}{39.10 \ g \ K} )(\frac{6.022 \cdot 10^{23} \ atoms \ K}{1 \ mol \ K} ) = 5.15797 × 10²³ atoms K

<u>Step 4: Check</u>

<em>We are given 4 sig figs. Follow sig figs and round.</em>

5.15797 × 10²³ atoms K ≈ 5.158 × 10²³ atoms K

A(g) + 2B(g) → C(g) + D(g)
WITCHER [35]

Answer:

0.169

Explanation:

Let's consider the following reaction.

A(g) + 2B(g) ⇄ C(g) + D(g)

We can find the pressures at equilibrium using an ICE chart.

       A(g) + 2 B(g) ⇄ C(g) + D(g)

I       1.00     1.00        0        0

C       -x        -2x        +x       +x

E    1.00-x  1.00-2x     x         x

The pressure at equilibrium of C is 0.211 atm, so x = 0.211.

The pressures at equilibrium are:

pA = 1.00-x = 1.00-0.211 = 0.789 atm

pB = 1.00-2x = 1.00-2(0.211) = 0.578 atm

pC = x = 0.211 atm

pD = x = 0.211 atm

The pressure equilibrium constant (Kp) is:

Kp = pC × pD / pA × pB²

Kp = 0.211 × 0.211 / 0.789 × 0.578²

Kp = 0.169

how would you write equation to show how buffers H2CO3 and NaHCO3 behave when (a) HCl is added and (b) NaOH is added.
Vlad1618 [11]
<span>H2CO3 <---> H+ + HCO3-
NaHCO3 <---> Na+ + HCO3-

When acid is added in the buffer, the excess H+ of that acid reacts with HCO3- to form H2CO3, and due to this NaHCO3 dissociates into HCO3- to attain the equilibrium. and hence there is no net effect of H+ due to pH remain almost constant. when a base is added to the buffer, the OH- ion of base react eith H+ ion present in buffer, then to attain equilibrium of H+ ion, the H2CO3 dissociates to produce H+ ion, but now there is the excess of HCO3- due to which Na+ ion react with them to attain equilibrium of HCO3-. hence there is again no net change in H+ ion due to which pH remain constant.....</span>
