Answer:

Extrusive igneous rock

Explanation:

The igneous rocks that are crystallized on the earth's surface are commonly known as the extrusive igneous rock. These rocks are characterized by the presence of fine-grained crystals which is due to the rapid cooling of the magma, as it does not get enough time for the crystals to form. These are also sometimes comprised of volcanic glasses.which are formed on the surface due to the eruption of volcanoes.

When the hot intruding magma crystallizes below the earth's surface, then it is called intrusive igneous rocks. For example, granite, diorite and gabbro.

On the other hand, when the hot uprising magma crystallizes on or near the earth's surface, then it is known as extrusive igneous rocks. For example, basalt, rhyolite and andesite.

You believe you have cracked a secret code that uses elemental symbols to spell words. The code uses numbers to designate the el

Stells [14]

Explanation:

Atomic numbers for neutral atoms are the same as the number of electrons. The number of electrons are used in writing the subshell notation where we can see the highest princpal quantum number(n).

In order to solve this problem, a good knowledge of the periodic table and shell notation is required.

For example;

Given a number 5;

We know the number is made of both the atomic number of the element and the highest quantum number.

It is easier for us to know the highest quantum number from the shell notation:

shell notation 1s²2s²2p¹

highest principal quantum number is 2

We are left with atomic number 5-2, which is 3

The element is therefore Li.

Which of the following compounds contains the Lead (II) ion? PbO PbCl4 Pb2O Pb2S

KATRIN_1 [288]

PbO Let's look at each of the 4 compounds and see what's needed. PbO. * Oxygen has a valance shell that's missing 2 electrons and wants to get those 2 elections. Lead donates them, so you have a Lead (II) ions. This is a correct choice. PbCl4 * Chlorine wants to grab 1 electron to fill it's valance shell and Lead donates that election. However, there's 4 chlorine atoms and every one of them wants and electron, and lead is donating all 4 of the desired electrons making the Lead (IV) ion. So this is a bad choice. Pb2O * Oxygen still wants 2 electrons and gets them from the lead. But there's 2 lead atoms and each of them donates 1 election making for 2 Lead(I) ions. So this too is a bad choice. Pb2S * Sulfur is in the same column of the periodic table as oxygen and if this compound were to exist would have similar properties as Pb2O and would have Lead(I) ions. So this is a bad choice.

Which equation is balanced?

vichka [17]

Answer:

2Na+F2 yields 2NaF is balanced.

Explanation:

There are 2 sodium and 2 fluorine in both reactants and product: In 2NaF the 2 is distributed because it is in the beginning of the compound.
