How many electrons does calcium lose when forming an ionic bond with another ion?
Advocard [28]
The correct answer is answer choice B, 2. Calcium is in Column 2, meaning that it has 2 electrons in its outermost energy level. These two electrons must be lost for it to form an ionic bond with another element and become stable.

Questions like these can be easily answered if you have a periodic table on hand. Elements in Column 1 need to lose 1 electron to form ionic bonds, elements in Column 2 need to lose 2, and so on. Keep in mind, however, that elements in the center of the table are more likely to form metallic or covalent bonds, and elements in Columns 16 and 17 need to gain 2 and 1 electrons, respectively.

You are given a sample resembling silver. Which of the following properties could be used to help determine whether the sample i
defon

Answer:

the density of the sample - the melting point of the sample

Explanation:

Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.

For example,

Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.

Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.

A buffer solution is prepared by adding NaC2H202
olganol [36]

Shift to reactants(left)

<h3>Further explanation </h3>

A buffer solution is a solution that can maintain a good pH value due to the addition of a little acid or a little base or dilution.

The buffer solution can be acidic or basic

Acid buffer solutions consist of weak acids and their salts.  

A buffer solution of NaC2H202    and HC2H2O2 (acetic acid) is included in the acid buffer

So :

a slight addition of acid (H⁺) will be balanced by the conjugate base

the addition of a small base (OH⁻) will be balanced by the weak acid

With the addition of acid (H +), the equilibrium will shift to the left, in the formation of CH3COOH. The added acid will be neutralized by the conjugate base component (CH3COO−).
