Hello!

If a reaction occurs when a piece of metal is placed in a solution, you can conclude that the solution is <span>probably acidic because bases rarely react with metals.

Strong Acids, like HCl, react with metals to produce salts and release gaseous hydrogen (H</span>₂) which is evidenced by the generation of bubbles in the solution. The general chemical equation for this kind of reactions for a metal M and an acid HA is:

2M(s) + 2HA(aq) → 2MA(aq) + H₂(g)

What kind of intermolecular forces act between a sodium cation and an ammonia molecule? Note: If there is more than one type of

Reil [10]

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.

the trunk of a certain tree is 50 cm thick. Each year it gets thicker by 1 cm. How thick will the tree trunk be in 50 years

Mama L [17]

100 centimeters thick

Starting thickness was 50 cm
1 cm every 50 years= 1x50
1x50=50
Old thickness + New thickness= 50 + 50 = 100 cm
