why do you think you can find silver and gold on their own in rocks but calcium and magnesium are combined with other elements t
katrin [286]

Explanation:

Silver and Gold belong to a special group of metals known as the native metals. They are found naturally on their own and not in combined form in rocks.

  • These metals are found uncombined because they are unreactive.
  • They prefer to alloy with themselves.
  • Calcium and magnesium on the other hand are reactive metals.
  • The unreactivity of these metals makes them uncombined in nature.

Amiraneli [1.4K]

Answer:

Sodium is a silvery-white metal that reacts with chlorine gas, which is a yellow-greenish gas that is toxic. The  reaction gives off a lot of heat. After the reaction, which statement is true about the chemical properties of the product, sodium chloride?

Pure sodium reacts violently and sometimes explosively with water producing sodium hydroxide, hydrogen gas and heat

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Chlorine is a very poisonous yellow green gas with a sharp odour that was used in gas warfare during WW1

Sodium and chlorine reacts with each other, however, to produce one of the most familiar substance used in cooking and preservation industry today Sodium Chloride or Common salt or table salt in the irreversible equation;

2Na(s) + Cl2(g) → 2NaCl(s)

Explanation:

It is easy to see why this reaction takes place so readily sodium has one electron in its outermost valence shell while chlorine has seven electrons in its valence shell. when sodium atom transfers one electron to chlorine atom forming a sodium cation (Na+) and a chloride anion (Cl-) both ions have complete valence shells and are energetically more stable. the reaction is extremely exothermic, producing a bright yellow light and a great deal of heat and fumes of sodium chloride.

In a reaction observation of the reaction process you will see sodium flares up almost immediately upon reaction with water.

If one iron nail weighs 2.0 grams, what would be the mass of 6.022 x 10^23 nails?
Maru [420]

Answer:

1.2x10^{24}g

Explanation:

Hello!

In this case, it is possible to treat this problem by using a proportional factor which indicates one iron nail equals 2.0 grams:

\frac{2.00g}{1nail}

Now, for an amount of 6.022x10²³ nails, the corresponding mass will be:

6.022x10^{23}nail*\frac{2.00g}{1nail} \\\\1.2x10^{24}g

Best regards!

How can indicator be used to determine if a solution is an acid or base
dalvyx [7]

Answer:

To tell if something is an acid or a base, you can use a chemical called an indicator. An indicator changes color when it encounters an acid or base. There are many different types of indicators, some that are liquids and others that are concentrated on little strips of "litmus" paper.
