Because the law states that matter can neither be created nor destroyed but changed in form. And the same goes for energy that the body takes from the food, we give off that energy through heat and movement. Hope this helped!

A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin
Shtirlitz [24]
Answer:
            <span>Based on giveninformation, the compound is a <u>Poly Unsaturated</u> fatty acid.

Explanation:
                   Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
                                      Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids. 

Examples:
                 Lauric Acid           </span>CH₃(CH₂)₁₀COOH<span>

                 Myristic Acid         </span>CH₃(CH₂)₁₂COOH<span>

                 Palmitic Acid         </span>CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
                                      Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids. 

Examples:
                 <span>Linoleic acid
</span>
                 <span>Vaccenic acid

                 </span><span>Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name H</span>exacosa-3,9-dienoic acid with following structure.

Hydrogen reacts with oxygen to form only water. if 16 grams of hydrogen is mized with 16 grams of oxygen, how much water can for
olchik [2.2K]
The balanced chemical equation will tell you the molar ratios in which hydrogen and oxygen react to form water:

2H2 + O2 ----> 2H2O

Then the ratio is 2 mol of H2 react with 1 mol of O2 and form 2 mol of H2O:

2 : 1 : 2

Now convert the given data into moles:

16 grams of H2 = 16 g / 2 g/mol = 8 mol

16 grams of O2 = 16 g / 16 g/mol = 1 mol.


Then you have that the 1 mol of oxygen will react with 2 moles of hydrogen and they will form  2 mol of H2O.

And you can calculate the mass of 2 moles of H2O by multiplying by its molar weigth: 18 g/mol.

2 mol H2O * 18 g/mol = 36 grams of water.

Then, the answer is 36 grams of H2O.

Anvisha [2.4K]

Answer:Ionic compounds form when positive and negative ions share electrons and form an ionic bond. ... The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero.

Explanation:Simple ions:  

Perchlorate ClO4- IO3-

Chlorate ClO3- BrO3-

Chlorite ClO2-

What is the molarity of a solution that contains 2.3 moles of NaCl in 0.45 L of solution
Andrews [41]
  The Molarity  of  solution  that  contain  2.3  mole  of  NaCl  in  0.45L  of  solution  is  calculated  using the  below    equation

=    molarity  = moles/volume  in  liters

=  2.3  moles/0.45 L  =   5.1  M
