The term sensitivity in Analytical Chemistry is "the slope of the calibration curve or a function of analyte concentration or amount".

<u>Answer:</u> Option B

<u>Explanation:</u>

In a sample, the little amounts of substances can be accurately evaluated by a method is termed as "Analytical sensitivity". This detect a target analyte like an antibody or antigen, process is considered as potential of a test to and generally demonstrated as the analyte's minimum detectable concentration.

The acceptable diagnostic sensitivity is not guaranteed by high analytical sensitivity. The percentage of individuals who have a given disarray who are identified by the method as positive for the disarray is known as "Diagnostic sensitivity".

ЗKOH + H3PO4=K3PO4 + 3H2O <br> what is the reaction
pentagon [3]

Answer: The given reaction is a neutralization reaction.

Explanation:

When an acid chemically reacts with a base then it leads to the formation of salt and water.

For example, 3KOH + H_{3}PO_{4} \rightarrow K_{3}PO_{4} + 3H_{2}O

Here, KOH is a the base and H_{3}PO_{4} is an acid which on chemical reaction with each other leads to the formation of salt (K_{3}PO_{4}) and water (H_{2}O).

Thus, we can conclude that the given reaction is a neutralization reaction.

During an exothermic reaction, heat content in the surroundings increases because
ANTONII [103]

Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.

<h3>What is an Exothermic Reaction ?</h3>

When a chemical reaction happens, energy is transferred to or from the surroundings.

When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.

ΔH value negative –> energy released –> exothermic reaction

This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.

The energy diagram for the exothermic reaction is attached with this answer.

A sample of gas contains 0.1900 mol of CO(g) and 0.1900 mol of NO(g) and occupies a volume of 22.0 L. The following reaction tak
worty [1.4K]

Answer:

V₂ = 16.5 L

Explanation:

To solve this problem we use <em>Avogadro's law, </em>which applies when temperature and pressure remain constant:

V₁/n₁ = V₂/n₂

In this case, V₁ is 22.0 L, n₁ is [mol CO + mol NO], V₂ is our unknown, and n₂ is [mol CO₂ + mol N₂].

  • n₁ = mol CO + mol NO = 0.1900 + 0.1900 = 0.3800 mol

<em>We use the reaction to calculate n₂</em>:

2CO(g) + 2NO(g) → 2CO₂(g) + N₂(g)

  • mol CO₂:

0.1900 mol CO * \frac{2molCO_{2}}{2molCO} = 0.1900 mol CO₂

  • mol N₂:

0.1900 mol NO * \frac{1molN_{2}}{2molNO} = 0.095 mol N₂

  • n₂ = mol CO₂ + mol N₂ = 0.1900 + 0.095 = 0.2850 mol

Calculating V₂:

22.0 L / 0.3800 mol = V₂ / 0.2850 mol

V₂ = 16.5 L
