Answer: Option (b) is the correct answer.

Explanation:

A combustion reaction is defined as the reaction in which a substance chemically reacts in the presence of oxygen.

A combustion reaction is always exothermic in nature as heat is released. Also, carbon dioxide and water will be produced in a combustion reaction.

For example, CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O

Therefore, we can conclude that an essential condition for a combustion reaction is that oxygen is a reactant.

Copper has a density of 8.96 g/cm3. If 75.0 g of copper is added to 50.0 mL of water in a graduated cylinder, to what volume rea
Tcecarenko [31]

Answer:

The answer to your question is    Final volume = 58.37 ml

Explanation:

Data

density = 8.96 g/cm³

mass = 75 g

volume of water = 50 ml

Process

1.- Calculate the volume of copper

  Density = mass / volume

Solve for volume

  Volume = mass / density

Substitution

  Volume = 75/8.96

Simplification

  Volume = 8.37cm³    or 8.37 cm³

2.- Calculate the new volume of water in the graduated cylinder

  Final volume = 50 + 8.37

  Final volume = 58.37 ml

Why are large differences in temperature between the wet bulb and dry bulb thermometers are possible only at higher temperatures
photoshop1234 [79]

Answer:

At constant vapor pressure, the relative humidity decreases as the temperature increases, therefore, at higher temperature the relative humidity is low and water readily evaporates from the wet bulb thermometer that results in the cooling of the bulb such that at a given ambient temperature the very low relative humidity results in very large differences between the temperatures of the wet bulb thermometer and that of the dry bulb thermometer and the wet bulb is observed to be the colder thermometer of the two
