Answer:
Precipitation
Explanation:
Let's consider the balanced chemical equation between barium acetate and sodium carbonate to form barium carbonate and sodium acetate.
Ba(C₂H₃O₂)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + 2 NaC₂H₃O₂(aq)
Both products and reactants are salts. But, among the products, barium carbonate is solid. This allows us to classify it as a precipitation reaction.
Answer:
A: Beryllium (Be)
Explanation:
the traits listed are traits of metals, and beryllium is the only choice presented that is a metal.
Answer:
Because the specific heat of the metal is less than the specific heat of water.
Explanation:
Hello, happy to help you today!
In this case, we need to analyze a property called "specific heat" which accounts for how much energy is required to increase or decrease the temperature of 1 g of the substance by 1 °C.
In this case, since the specific heat of water is about 4.184 J/g°C and the specific heat of metals in general is greater than zero, of course, but less than one, we can infer that for the same amount of energy, when they are in contact, more grams of metal will be cooled down to those of water heated up, because the specific heat of the metal is less than the specific heat of water.

The question is incomplete. The complete question is
In the molecule on the left, areas that have a partial negative charge are pink and areas that have a partial positive charge are blue. The molecule on the right is nonpolar.
What will most likely happen when these molecules get closer?
The molecules will repel each other because of a dipole-dipole interaction. The molecules will attract each other because of a dipole-dipole interaction. An induced dipole will be produced in the molecule on the right. An induced dipole will be produced in the molecule on the left.
Answer:
An induced dipole will be produced in the molecule on the right.
Explanation:
The molecule on the left already possesses a dipole. A dipole means the presence of a negative end and a positive end in a molecule.
Hence when the other molecule approaches, the polarized molecule induces a dipole on it. This second kind of dipole is known as 'induced dipole' hence the answer.
Elements in the same column of the periodic table exhibit similar properties (periodicity). Carbon, in Group XIV (14), and elements below it in the same column react in similar fashion. The most similar element to carbon is silicon (Si).
