Answer:
Ion-dipole forces
Explanation:
Na⁺ is a cation, that is, an ion with a positive charge.
NH₃ has polar covalent bonds (due to the difference in electronegativity between nitrogen and hydrogen). According to the VESPR theory, it has a trigonal pyramidal shape with a lone pair. As a consequence, it has a net dipole moment and the molecule is polar.
The intermolecular forces between Na⁺ (ion) and NH₃ (dipole) are ion-dipole forces.
Answer:
The speed of a spound wave in this water is 1484.1 m/s
Explanation:
Step 1: Data given
Frequency = 349.2 Hz
Wavelength = 4.25 m
Step 2: Calculate the speed
v = f*λ
⇒ with v= the speed of a sound wave in this water
⇒ with f = the frequency = 349.2 Hz
⇒ with λ = the wavelength = 4.25 m
v = 349.2 Hz * 4.25 m = 1484.1 m/s
The speed of a spound wave in this water is 1484.1 m/s
Answer:
The answer is
<h2>29.48 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of lead = 2.6 cm³
density of lead = 11.34 g/cm³
The mass of lead is
mass = 11.34 × 2.6 = 29.484
We have the final answer as
<h3> 29.48 g</h3>
Hope this helps you
Explanation:
When ethyne undergoes a hydrogenation reaction with Ni catalyst and excess hydrogen,
C2H2 + 2H2 => C2H6.
Ethyne reacts with hydrogen gas to form ethane.
