Answer:
Option A = 17.03 g/mol
Explanation:
Given data:
Atomic mass of nitrogen = 14.01 g/mol
Atomic mass of hydrogen = 1.008 g/mol
Molecular mass of NH₃ = ?
Solution:
Molecular mass of NH₃ = (14.01 g/mol × 1) + (1.008 g/mol × 3)
Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol
Molecular mass of NH₃ = 17.03 g/mol
Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.
Answer:
Im assuming a glass of water
Explanation:
there is less water that needs to be heated up
Answer:
0.33 ml
Explanation:
Formula for density: p = m/V (where p is <em>density</em>, m is <em>mass</em> and V is <em>volume</em>)
So, by applying the above formula:
Answer:
This is a substance that has definite composition
Explanation:
chemicals are substances that can not be broken down any further by physical process.it is a form of matter having a constant chemical characteristics and properties
Hello!
The statement that a solution of sodium acetate (CH₃COONa) is weakly basic is true:
Sodium acetate is the conjugate base of Acetic Acid. When sodium acetate is dissolved in water, it follows the equation that is shown below:
CH₃COONa(s) → CH₃COO⁻(aq) + Na⁺(aq)
Now the Acetate (CH₃COO⁻) ion, has an equilibrium in water to produce hydroxyl (OH⁻) ions and (Acetic Acid CH₃COOH)
CH₃COO⁻ + H₂O ⇄ CH₃COOH + OH⁻
This is a weak equilibrium, and the hydroxyl ions cause the solution to be weakly basic.
Have a nice day!
