What is the average atomic mass of element X:

Chemistry
1 answer:
Fiesta28 [93]2 years ago
4 0

The average atomic mass of element X is 10.025 amu

The average atomic mass of element X = atomic mass of 10 isotope × relative abundance of 10 isotope + atomic mass of 11 isotope × relative abundance of 11 isotope + atomic mass of 12 isotope × relative abundance of 12 isotope

= 10 × 98% + 11 × 1.5 % + 12 × 0.5 %

= 10 × 0.98 + 11 × 0.015 + 12 × 0.005

= 9.8 + 0.165 + 0.06

= 10.025 amu

So, the average atomic mass of element X is 10.025 amu

Which of the following reactions is endothermic?
Andreyy89
<h2>Which of the following reactions is endothermic-</h2><h2>½N2(g) + O2(g) + 8.1 kcal → NO2(g)</h2>

Explanation:

Chemical reaction

When two or more substances react and form some new substance it is called as chemical reaction .

A + B --> C + D

(reactants )   (products )

When ever chemical reaction occurs following changes can occur :

  • Change in colour
  • Ppt formation
  • energy changes
  • Change in state
  • Evolution of gas etc

On the basis of energy changes : reactions are of two types :

Endothermic

Exothermic

Endothermic reaction

A reaction in which heat is absorbed .

Example :½N2(g) + O2(g) + 8.1 kcal → NO2(g)

Exothermic reaction

A reaction in which heat is released .

For example : H2(g) + ½O2(g) → H2O(g), ΔH = -57.82 kcal

½N2(g) + 3/2H2(g) → NH3(g) + 11.0 kcal

C(diamond) + O2(g) → CO2, ΔH = -94.50 kcal

Is the atom indicated with an arrow nucleophilic, electrophilic, acidic, more than one of these choices, or none of these choice
CaHeK987 [17]

Answer:

c) acidic

Explanation:

pKa is a value which describes the acidity of a solution. The solution is pKa ≤ 25 which means that the solution is more acidic. The lower value of pKa tells us that the solution is more acidic but when the pKa value of solution increases the acidity of the solution is also decreases. Due to lower value of pKa, the acid in the solution is fully dissociates in water.-5 to 50 is the range of the value of pKa for different solutions.
