2.54×10^{24} sodium ions in 2.11 mol of sodium carbonate.

<h3>What is sodium carbonate?</h3>

The sodium carbonate, the inorganic substance with the Na_2CO_3 formula, is also known as washing soda, soda ash, and soda crystals.

All of the forms are water-soluble, odourless, white salts that produce slightly alkaline solutions in water. In the past, it was recovered from the ashes of plants that were raised in soils high in salt.

The term "soda ash" originated to refer to sodium carbonate because the ashes of these sodium-rich plants were probably distinct from the wood ashes that were originally used to make potash. The Solvay technique is used to produce it in large amounts from limestone and sodium chloride.

How many grams of water will be produced from 50 g hydrogen reacting with 50 g oxygen?
DanielleElmas [232]

We need to first come up with a balanced equation:


4H+O_{2} → 2H_{2}O


We know that the molar ratio of hydrogen to oxygen to water now is 4:1:2.


Converting the amount of grams given to moles is as follows:


Hydrogen: \frac{1mole}{1.008g}*50g=49.6mol


Oxygen: \frac{1mole}{15.999g}*50g=3.125mol


We know now that the limiting reactant is oxygen. We can then know that the number of moles of water are produced are double the number of moles of oxygen used due to the ratio that we established at the beginning - 4:1:2.


So we now can use 6.25 moles of water as the amount produced.


Then we convert moles of water to grams:


\frac{18.015g}{1mole} *6.25mol=112.59g


Now we know that there are 112.59g of water produced when we start with 50g of hydrogen and 50g of water.

Burning wood to power engines and machines ushered in the Industrial Revolution in 1769.Coal became the major fuel in the early
Sloan [31]

Answer:

Natural gas combustion equation:

CH4 + O2 ==> CO2 + 2 H2O + HEAT

Octane or oil combustion equation:

2C8H18 + 25 O2 ===> 16CO2 + 18 H2O.

If these fuels were replaced by self-sustaining energy sources, the contamination of the environment would be less, since their combustion generates toxic compounds that damage the ozone layer, promoting the greenhouse effect, increasing the Earth's temperature and also promoting the increase in the passage of ultraviolet radiation.

Explanation:

The combustion reactions are exothermic, and irreversible, they can be complete and incomplete combustions.

They always consist of oxygen as a reagent and water and carbon dioxide as a product (complete), in the case of the incomplete the difference is that the products vary and there may be waste or chemical compounds that failed to burn.

The recommended dose for acetaminophen is 10.0 to 15.0mg/kg of body weight for adults using this guideline calculate the maximum
Oxana [17]

Answer:

1422mg of acetaminophen

Explanation:

The maximum dose of acetaminophen is 15.0 mg of acetaminophen per kg of person.

To know the maximum single dosage of the person we need to convert the 209lb to kg (Using 1kg = 2.2046lb):

209lb * (1kg / 2.2046lb) = 94.8

The person weighs 94.8kg and the maximum single dosage for the person is:

94.8kg * (15.0mg acetaminophen / kg) =

1422mg of acetaminophen
