Answer:
Visible Light
Explanation:
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.
Answer:
<h2>91.2</h2>
Explanation:
Given that:
Temperature = 60 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (60 + 273.15) K = 333.15 K
n = 5.14 × 10⁻³ mol
V = 1,171 mL = 1.171 L ( 1 mL = 0.001 L)
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 62.364 L Torr/ K mol
Applying the equation as:
P × 1.171 L = 5.14 × 10⁻³ mol × 62.364 L Torr/ K mol × 333.15 K
<u>⇒P = 91.2 torr</u>
Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed</span>
Gaseous, meaning <span>relating to or having the characteristics of a gas</span><span>:
</span>
