consider the combustion of pentane, balanced chemical reaction shown. how many moles of carbon dioxide are produced with the combustion of 3 moles of pentane? C5H12 (1) + 8 O2 (g) → 6 H20 (1) + 5 CO2 (g)

Answers

Answer 1

Answer:

The balanced chemical reaction for the combustion of pentane is:

C5H12 + 8 O2 → 6 H2O + 5 CO2

According to the balanced equation, 1 mole of pentane (C5H12) produces 5 moles of carbon dioxide (CO2).

To determine how many moles of carbon dioxide are produced with the combustion of 3 moles of pentane, we can use the mole ratio from the balanced equation:

3 moles of C5H12 × (5 moles of CO2 / 1 mole of C5H12) = 15 moles of CO2

Therefore, 3 moles of pentane would produce 15 moles of carbon dioxide.

If an object weighs 3.4526 g and has a volume of 23.12 mL, what is its density?
Select one:
a. 0.15 g/mL
b. 0.149 g/mL
c. 1.50 x 10^-1 g/mL
d. 0.1493 g/mL

Answers

If an object weighs 3.4526 g and has a volume of 23.12 mL, the density of the object will be 0.1493 g/mL.

Density calculation

To calculate the density of an object, you need to divide its mass by its volume. In this case, the mass of the object is 3.4526 g and its volume is 23.12 mL.

Density = Mass / Volume

Density = 3.4526 g / 23.12 mL

Calculating the density:

Density ≈ 0.1493 g/mL

In other words, the density of the object is 0.1493 g/mL.

name a substance which can oxidize i- to i2, but cannot oxidize br- to br2

Answers

The substance that can oxidize I-to-I2 but cannot oxidize Br-to-Br2 is chlorine. Chlorine can be used as an oxidizing agent to convert I- to I2, but it is not capable of oxidizing Br- to Br2.

This is due to the relative strengths of the halogens. Chlorine is a stronger oxidizing agent than iodine, but bromine is stronger than both chlorine and iodine. Therefore, chlorine is capable of oxidizing iodide ions to iodine, but it cannot oxidize bromide ions to bromine because bromine is a stronger oxidizing agent than chlorine.

In the presence of iodide ions (I-), chlorine (Cl2) can oxidize iodide ions to produce iodine (I2) and chloride ions (Cl-). 2 I- (aq) + Cl2 (aq) → 2 Cl- (aq) + I2 (s)In the presence of bromide ions (Br-), chlorine (Cl2) is unable to oxidize bromide ions to produce bromine (Br2) and chloride ions (Cl-). 2 Br- (aq) + Cl2 (aq) → no reaction

Answers

Ringer solution is often described as normal saline solution modified by the addition of electrolytes.

Ringer solution is a type of intravenous fluid used in medical settings for various purposes, such as hydration and replenishing electrolytes. It is considered as a modified form of normal saline solution, which is a solution of sodium chloride (salt) in water. Ringer solution is modified by the addition of electrolytes, which are substances that dissociate into ions and carry an electric charge when dissolved in water.

The addition of electrolytes in Ringer solution serves to mimic the electrolyte composition of the human body, helping to maintain the balance of ions and fluids. These electrolytes typically include sodium, potassium, calcium, and bicarbonate ions. By providing a more balanced electrolyte composition, Ringer solution can better support vital bodily functions, such as nerve conduction, muscle contraction, and pH regulation.

The specific composition of Ringer solution may vary depending on its intended use and the medical condition of the patient. For example, Ringer's lactate solution contains sodium chloride, potassium chloride, calcium chloride, and sodium lactate. This variant is commonly used in cases of fluid loss and metabolic acidosis.

Overall, the modification of normal saline solution by the addition of electrolytes in Ringer solution helps to create a more balanced and physiologically compatible fluid for medical applications.
