Approximately how many plant made pharmaceuticals are currently under different stages of discovery?

At equilibrium, both the forward reaction and the reverse reaction occur simultaneously and at the same rate. Since the rates ar

Alja [10]

Answer:

The value of the gas equilibrium constant Kp is 18.3

Explanation:

Step 1: Data given

Kp= Kc(RT)^Δn

Temperature = 298 K

Kc = 18.3

Step 2: The balanced equation

C₄(s) + 4 O₂(g) ⇌ 4 CO₂(g)

Step 3: Calculate Kp

Kp= Kc(RT)^Δn

⇒with Kp = the gas equilibrium constant = TO BE DETERMINED

⇒with Kc = the equilibrium constant = 18.3

⇒R = the gas constant = 0.08206 L* atm/mol*K

⇒T = the temperature = 298 K

⇒Δn = mol gas phase product – mol gas phase reactant = 4-4 =0

Kp = 18.3 * (0.08206*298)^0

Kp = 18.3 * 1

Kp = 18.3

The value of the gas equilibrium constant Kp is 18.3

<u>Atomic Structure</u>

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

<h3>Explanation:</h3>

<u>Step 1: Define</u>

3.93 × 10²⁴ molecules CCl₄

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

Avogadro's Number

Molar Mass of C - 12.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CCl₄ - 12.01 + 4(35.45) = 153.81 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 3.93 \cdot 10^{24} \ molecules \ CCl_4(\frac{1 \ mol CCl_4}{6.022 \cdot 10^{23} \ molecules \ CCl_4})(\frac{153.81 \ g \ CCl_4}{1 \ mol \ CCl_4})$
Multiply: $\displaystyle 1003.77 \ g \ CCl_4$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

1003.77 g CCl₄ ≈ 1000 g CCl₄

A solution of copper sulfate (CuSO4) produced by bioleaching has a concentration of 0.319 g/dm3 Relative atomic masses (Ar): Cu

Tanya [424]

moles Cu produced : 0.002

<h3>Further explanation</h3>

Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³

MW CuSO₄ :

$\tt =63.5+32+4\times 16=159.5~g/mol$

mol CuSO₄ /dm³ :

$\tt \dfrac{0.319}{159.5}=0.002$

CuSO₄⇒Cu²⁺ + SO₄²⁻

mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002
