Given the following equation: Na2O + H20 - 2 NaOH
How many grams of Na20 are required to produce 1.60 x 102
grams of NaOH?
g

Answers

Answer 1

Answer:

124g  

Explanation:

Answer 2

The concept stoichiometry is used here to determine the mass of Na₂O. The grams of Na₂O required to produce 1.60 x 10² grams of NaOH is  124 g.

What is Stoichiometry?

The stoichiometry is an important concept of chemistry which help us to use the balanced chemical equation to calculate the amounts of reactants and products. The stoichiometric coefficient is the number of molecules that can participate in the reaction.

The balanced equation is:

Na₂O + H₂O → 2NaOH

1 mole of Na₂O is required to react with 1 mole of  H₂O to give 2 moles of NaOH.

62 g of Na₂O produces 80 g of NaOH.

1 g of NaOH is produced from 62/80 g of Na₂O .

1.6 × 10² g of NaOH will require 62 × 1.6 × 10² g / 80 g of Na₂O = 124 g Na₂O

Thus the grams of Na₂O required to produce 1.6 × 10² g of NaOH is 124 g.

Find the amount of water containing 14.02 * 10²⁴ molecules​

Answers

Answer:

14.02 x 10²⁴ molecules

Explanation:

To solve this problem we will use Avogadro's number: It relates to the number of molecules (or atoms) contained in 1 mol of any given substance:

14.02 x 10²⁴ molecules ÷ 6.023 x 10²³ molecules/mol = 23.28 moles

Thus, 23.28 moles of water contain 14.02 x 10²⁴ molecules.

Why do you think males and children are more likely to die from DHMO

Answers

Answer:

Dihydrogen Monoxide (DHMO) is perhaps the single most prevalent of all chemicals that can be dangerous to human life. Despite this truth, most people are not unduly concerned about the dangers of Dihydrogen Monoxide. Governments, civic leaders, corporations, military organizations, and citizens in every walk of life seem to either be ignorant of or shrug off the truth about Dihydrogen Monoxide as not being applicable to them. In 1997, the Dihydrogen Monoxide Research Division was formed and went online spreading the truth about DIHYDROGEN MONOXIDE. As word has spread, so too has the public awareness of Dihydrogen Monoxide and its implications involving the Internet and accessibility of such information. To that end, the DMRD's web site at DHMO.org continues to provide the most comprehensive collection of Dihydrogen Monoxide information available anywhere.

Explanation:

DHMO has been the dihydrogen monoxide. It has been responsible for the death of males and children as it causes tissue damage.

The DHMO has been the hydric acid and is one of the major constituents of acid rain. Gas has been responsible for greenhouse gas. Ingestion may lead to tissue damage with symptoms of nausea, vomiting, and electrolyte imbalance.

The companies dumping waste in the rivers and lakes have been warned for the removal of DHMO as it has been harmful to the males and children, and results in death.

Answers

Answer:

In diamond the carbon atoms are covalently bonded as flat sheets

In silicon(IV) dioxide the silicon and oxygen atoms are covalently bonded in flat sheets

The structure of copper includes a lattice of positive ions

Explanation:

Diamond and silicon(IV) dioxide are covalent network solids. Covalent network solids are made up of atoms joined to one another by covalent bonds to form a giant lattice, The solids are hard and have a very high melting point. They do not conduct electricity. So, for both diamond and SiO2, atoms are covalently bonded to yield flat sheets in a covalent bonded network solid.

Copper is a metallic substance having metallic bonds, a metallic crystal consists of positive ions and a cloud of electrons.

According to the stoichiometry of the decomposition of water 6.04  grams of oxygen is produced assuming the decomposition goes to completion.

What is stoichiometry?

Stoichiometry is  defined as the determination of proportions of elements or compounds which are present  in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is useful in balancing chemical equations.According to the reaction, 36 g water gives 32 g oxygen thus 6.80 g water will give 6.80×32/36=6.04 g.

Thus, on  decomposition of water 6.04  grams of oxygen is produced assuming the decomposition goes to completion.

The usual culprit is burning coal.

Explanation:

This produces a lot of carbon dioxide as well as sulphur dioxide. Other industrial processes, and vehicle emissions, produce similar oxides unless they are 'scrubbed' out. They react with atmospheric moisture to produce acids like carbonic, sulphurous and nitrous acids. Which is then precipitated. It should be remembered that a volcanic eruption has this effect too.
