sveticcg [70]
<span>The answer is lactic acid/lactate. This is caused by anaerobic respiration in muscles especially during strenuous physical activity due to low oxygen supply to muscles in respect to the demand. When there is sufficient oxygen in the muscles, pyruvate is broken down aerobically in the Kreb’s cycle. However, it is converted to lactate in the anaerobic pathway. Lactic-acidosis occurs when lactic acid accumulates in tissues and slows down metabolic pathways</span>

Water is produced from the reaction of hydrogen and oxygen gas, according to the equation below. What is the excess reactant in
liq [111]

Explanation:

Mole ratio of Oxygen to Hydrogen gas = 1 : 2.

If we use 3.0 moles of oxygen gas, we would need 3.0 * 2 = 6.0 mol of hydrogen gas.

However we only have 4.2 mol of hydrogen. Therefore hydrogen is limiting and oxygen is in excess. (B)

Why are the three atoms are isotopes of magnesium
LenKa [72]

Answer:

Magnesium is a naturally ubiquitous; (appearing & found evrywhere) element and has three naturally occurring stable isotopes, 24Mg, 25Mg and 26Mg, with relative abundance of 78.99%, 10.00% and 11.01%, respectively.

However, they differ only because a 24Mg atom has 12 neutrons in its nucleus, a 25Mg atom has 13 neutrons, and a 26Mg has 14 neutrons.

What is the Law of the Conservation of Mass
Fantom [35]

Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.

thus, the mass of the reactants in a reaction must be equal to the mass of the products

Calculate the number of molecules present in 3.50 mol feo2. 2.11 x 1024 molecules 2.107 x 1023 molecules 3.50 x 1023 molecules

Calculate the number of molecules present in 3.50 mol feo2. 2.11 x 1024 molecules 2.107 x 1023 molecules 3.50 x 1023 molecules <u>3.5*(6.02*10^23)=2.107*10^24 molecules</u>

<h3>What is molecules?</h3>

A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds. Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.

The fundamental building block of an element is an atom. They are made up of an electron-surrounded nucleus. An atom is considered to have valence electrons if its electron shell is not completely complete. A chemical (covalent) connection is created and a lower energy state is entered when two or more atoms join forces to share outer shell valence electrons. In an exothermic reaction, energy is released as atoms bond.
