Answer:

The answer to your question is 6

Explanation:

Data

Cu + 2AgNO₃ ⇒

To find the answer, count the number of each element in the reactants

Element Quantity

Copper 1

Silver 2

Nitrogen 1

Oxygen 6

Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.

1. How many atoms are there in 2.8 moles of carbon? You must show your work to receive credit.

Zolol [24]

Answer:

The answer to your question is

1.- 1.686 x 10²⁴ atoms

2.- 0.25 moles

Explanation:

1.-

1 mol ---------------- 6.023 x 10²³ atoms

2.8 moles ---------- x

x = (2.8 x 6.023 x 10²³) / 1

x = 1.686 x 10²⁴ atoms

2.- 1 mol ------------------ 6.023 x 10 ²³ molecules

x moles ------------- 1.50 x 10²³ molecules

x = (1.50 x 10²³ x 1) / 6.023 x 10²³

x = 0.25 moles

Consider the following equilibrium: CO2(g) + C(graphite) 2CO(g); ΔH = 172.5 kJ The equilibrium constant for this reaction will

bezimeni [28]

Answer: Option (B) is the correct answer.

Explanation:

As the given reaction is as follows.

$CO_{2}(g) + C(graphite) \rightarrow 2CO(g)$

Equilibrium constant for this reaction will be as follows.

$K_{c} = \frac{[CO_{2}]}{[CO]^{2}}$

According to Le Chatelier's principle, when we increase the temperature then the equilibrium will shift towards the right hand side.

As a result, concentration of carbon dioxide will decrease whereas concentration of carbon monoxide will increase.

Thus, we can conclude that in the given reaction equilibrium constant for this reaction will decrease with increasing temperature.

Mkey [24]

Answer:

The concentration is 0.036 mg/mL

Explanation:

Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL
