Answer:

This chemical equation represents a synthesis reaction. This identification is based on the fact that the reactant chemical compounds combine to form a single chemical substance that is different from the initial chemical substance.

The type of reaction of Fe2O3 + 2SiO2 → Fe2Si2O7 would be that it is a synthesis reaction. It is a type of chemical reaction in which two or more simple substances combine to form a more complex product. Hope this answers the question.

Write the balanced chemical equations for the decomposition of solid calcium hydroxide into solid calcium (ii) oxide (lime) and

Lesechka [4]

Calcium oxide (CaO) or lime in solid form can be prepared from the decomposition of calcium hydroxide {Ca $(OH)_{2}$ in to lime (CaO) and water ( $H_{2}O$ at high temperature. The reaction is an endothermic reaction. That is heat is absorbed in this reaction process. One mole of calcium hydroxide decomposed into one mole of calcium oxide and one mole of water. The balanced reaction can be shown as-CaC $O_{3}$ (solid) → CaO (solid) + $H_{2}O$ (liquid). The heat of the reaction is (+) 63.7 kJ/mole of CaO.

Which of the following best describes an empirical formula?

Monica [59]

Answer:

Option C :

a chemical formula that shows the relative number of each type of atom in a molecule, using the smallest possible ratio

Explanation:

Empirical Formula:

Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.

So,

Tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule

For Example

C₂H₆O₂ Consist of Carbon (C), Hydrogen (H), and Oxygen (O)

Now

Look at the ratio of these three atoms in the compound

C : H : O

2 : 6 : 2

Divide the ratio by two to get simplest ratio

C : H : O

2/2 : 6/2 : 2/2

1 : 3 : 1

So for the empirical formula the simplest ratio of carbon to hydrogen to oxygen is 1:3:1

So the empirical formula will be

Empirical formula of C₂H₆O₂ = CH₃O

So, Option C is correct :

a chemical formula that shows the relative number of each type of atom in a molecule, using the smallest possible ratio

How many liters of carbon dioxide will 0.5 mole of lithium hydroxide (LiOH) absorb? (One mole of any gas occupies 22.4 L under c

Svet_ta [14]

Answer:

0.5 moles of LiOH will absorb 5.6 L of $CO_2$

Explanation:

According to law of conservation of mass, the sum of mass on the reactant side must be equal to the sum of mass on product side.

The balanced chemical equation is:

$2LiOH+CO_2\rightarrow Li_2CO_3+H_2O$

2 moles of LiOH absorb 1 mole of $CO_2$ i.e. 22.4 Liters at STP

0.5 moles of LiOH absorb

= $\frac{22.4}{2}\times {0.5}=5.6Liters$

0.5 moles of LiOH will absorb 5.6 L of $CO_2$

Which are processes that add to the genetic differences in siblings? Cheek all that apply. Interphase Independent assortment Cyt

dangina [55]

Answer:

Crossing over Mitosis

Explanation:

A process called meiosis ensures siblings share just about 50% of their genotype. That's how siblings can have different DNA. Meiosis is a form of cell division that is only used to produce a special category of cells, called gametes.
