Answer:

Igneous rock is the type of rock that forms as a result of cooling an crystallization

Explanation:

  • Rocks are either sedimentary, igneous or metamorphic based on the chemical composition and the mode of formation.
  • Igneous rocks are formed as a result of the cooling and crystallization of magma from volcanic eruptions.
  • Igneous rocks are either intrusive, which form deep in the crust or extrusive which form on the surface of the earth.
  • Sedimentary rocks are formed as a result of deposition, and cementation of sediments.
  • Metamorphic rocks, on the other hand, are formed from the sedimentary and igneous rocks during the rock cycle.

If the [A-]/[HA] ratio of a base/weak acid mixture changes from 10/1 to 1/10, how much does the pH change:
andreev551 [17]

Answer:

The pH changes by 2.0 if the [A-]/[HA] ratio of a base/weak acid mixture changes from 10/1 to 1/10.

Explanation:

To solve this problem we use the<em> Henderson-Hasselbach equation</em>:

  • pH = pKa + log [A⁻]/[HA]

Let's say we have a weak acid whose pKa is 7.0:

  • pH = 7.0 + log [A⁻]/[HA]

If the [A⁻]/[HA] ratio is 10/1, we're left with:

  • pH = 7.0 + log (10/1)
  • pH = 7.0 + 1
  • pH = 8.0

Now if the ratio is 1/10:

  • pH = 7.0 + log (1/10)
  • pH = 7.0 - 1
  • pH = 6.0

The difference in pH from one case to the other is (8.0-6.0) 2.0.

<em>So the pH changes by 2.0</em> if the [A-]/[HA] ratio of a base/weak acid mixture changes from 10/1 to 1/10.

<u>Keep in mind that no matter the value of pKa, the answer to this question will be the same.</u>

The chemical equation for the formation of ammonia is unbalanced. 3H2(g) + N2(g) -----&gt; NH3(g) If three molecules of hydrogen
mestny [16]

Answer: 2 molecules of ammonia

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the formation of ammonia is:

3H_2(g)+N_2(g)\rightarrow 2NH_3

According to stoichiometry,

3 molecules of hydrogen combines with 1 molecule of nitrogen to give 2 molecules of ammonia.

4. Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number
densk [106]

no it is not possible, because they both have the same number of valence electrons in each element. in a compound you are supposed to have two or more elements that have different numbers of valence electrons so when put together they for a compound.

A beaker containing 6.32 moles of PBr3, contains___
NISA [10]

Answer:

3.8 x 10²⁴molecules

Explanation:

Given parameters:

Number of moles  = 6.32moles

Unknown:

Number of molecules  = ?

Solution:

The number of moles can be used to derive the number of molecules found within a substance.

Now,

       1 mole of substance contains 6.02 x 10²³ molecules

     6.32 mole of PBr₃ will contain 6.32 x 6.02 x 10²³ = 3.8 x 10²⁴molecules
