What is the chemical equation for lactose and lactase?
The chemical equation for the breakdown of lactose by lactase is: C12H22O11 (lactose) + H2O → C6H12O6 (glucose) + C6H12O6 (galactose). Lactase is the enzyme that catalyzes this reaction, breaking down lactose into its constituent monosaccharides, glucose, and galactose. This process is essential for the digestion of lactose in individuals who are lactose intolerant.

What is the difference between plumbate and plumbite?
Plumbate and plumbite are two different chemical species of lead compounds. Plumbate refers to a compound in which lead is in its higher oxidation state of +4, typically in the form of PbO2. Plumbite, on the other hand, refers to a compound in which lead is in its lower oxidation state of +2, typically in the form of Pb(OH)2 or PbO. The key distinction lies in the oxidation state of lead within the compound.
What is the balanced equation for the reaction of oleic acid and iodine?
The balanced equation for the reaction of oleic acid (C18H34O2) and iodine (I2) is: C18H34O2 + 6I2 → C18H33I6O2 + 6HI. This equation shows that one molecule of oleic acid reacts with six molecules of iodine to form one molecule of iodine-substituted oleic acid and six molecules of hydrogen iodide. Balancing the equation ensures that the number of atoms of each element is the same on both sides of the reaction.
What is to the left in a chemical equation?
By convention, the reactants are to the left and the products are to the right. For equilibrium equations, since the reaction goes both ways it's more or less arbitrary.
What is the chemical equation for a rotting fruit?
The chemical equation for the rotting of a fruit involves a complex series of biochemical reactions. One of the main processes is the breakdown of carbohydrates into simpler sugars by enzymes, followed by the fermentation of those sugars by microorganisms, leading to the production of compounds like ethanol, acetic acid, and various gases such as carbon dioxide and methane. The overall process can be summarized as the decomposition of organic matter through microbial and enzymatic activity.
What is the purpose of a chemical equation?
I don't remember all of the mathematical names, but I do remember that you need to balance equations so that both sides will be equal. These are very simple examples but they will show you that balanced equations are equivalentto being equal.
Such as: (2+2)=4=(3+1) Both sides equal '4'.
Differing equations on opposite sides of the equal sign demonstrate that are differing ways to express a certain figure.
Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal '5'.
(8) - (3) =5= (4) + (1)
Hope this helps.
What is the chemical equation for methanol burning in oxygen?
CH4 + 2O2 → CO2 + 2H2O
Methane + Oxygen → Carbon dioxide + Water
Carbon dioxide and water vapor belong in the blank space of the chemical equation for the burning of fossil fuels, as the reaction involves the combustion of hydrocarbons in fossil fuels in the presence of oxygen to produce carbon dioxide and water vapor, along with heat energy.
What key feature must a chemical equation have for it to be classified as a combustion reaction?
The product must be oxidized, i.e, Oxygen must be on the reactant side. Also, the reactant will form its oxide and also liberate heat energy.
In case of hydrocarbons, Carbon Dioxide, water and heat energy will be liberated and it is a must when writing the chemical equation.
What is the balanced chemical equation for the combustion of methylcyclononane?
C10h20 + 15o2 --> 10co2 + 10h2o
Moronic site " making capitalization corrections " again! All letters are capitals.
The coefficients in a balanced chemical equation indicate the mole ratio between reactants and products. This allows us to determine the number of moles of each substance that participate in the reaction based on the stoichiometry of the reaction.
Is a chemical equation balanced when each sum of molecules is the same?
No, a chemical equation is balanced when the number of each type of atom is the same on both sides of the equation. This means that the total mass and charge is conserved in a balanced chemical equation.
What is the chemical equation for burning lead?
2Pb + O2 ----->2PbO then 2PbO + O2 ------> 2PbO2 some mixed oxide will be formed also 2PbO + PbO2 ----->Pb3O4
When magnesium oxide is burnt in air, an oxidation of the magnesium and reduction of some of the oxygen in the air occurs according to the equation:
2 Mg + O2 -> 2 MgO.
What suggestions would you provide to make chemical equation more information?
A chemical equation can be made more informative by adding additional information to the chemical equation. This is done as follows:
(i) Reaction conditions:The information regarding temperature, pressure, and catalyst etc. is provided above the arrow (→ or =) separating the reactants and products.
For example, nitrogen and hydrogen react to form ammonia under the condition; temperature =450°C, pressure =200-900 atm, and in the presence of a catalyst (a mixture of an iron and molybdenum).
(ii) Physical state of reactants and products:Information regarding the physical states of the reactants and precuts, can be provided by using the letters(s), (l), (g) and (aq) for solid, liquid, gas and a solution in water, respectively, at the end of the formula of the substance involved. For example, solid sodium metal reacts with water atomic room temperature to produce hydrogen gas, and a solution of sodium hydroxide in water. Then , the complete chemical equation is..
2Na(s) + 2H2O (l) → 2NaOH (aq) + H2 (g)
(iii) Heat absorbed or evolved:Chemical reactions proceed with the evolution or absorption of heat. The reactions in which heat is absorbed are called endothermic reactions. The reactions in which heat is given out are called exothermic reactions. This information is provided by adding a heat term only the product-side (right hand side) of the chemical equation. For example,
(a) When carbon is burnt in air (or oxygen) heat is evolved. Then, the chemical equation is written as,
C(s) + O2 (g) → CO2 (g) + Heat (393 kJ)
The reactions with +Heat term on the product side are called exothermic reactions, while those with -Heat term on the product side are called endothermic reactions.
(iv) Concentration of the reactants and products:This information is added to the chemical equation by adding the word dil. (for dilute) or conc.(for concentrated) before the formulae of the reactants and products. For example, in the reaction between zinc and dilute sulphuric acid, the term dil. is added before the formulae of sulphuric acid.
Zn(s) + dil. H2SO4(aq) → ZnSO4(aq) + H2(g)
(v) Rate of reaction:This information is not commonly added to the chemical equation. Sometimes, however, the term fast or slow may be added over the arrow, if the reaction is fast or slow. For example, the reaction between HCl and NaOH in solution is a fast reaction. So,
HCl (aq) + NaOH(aq) fast NaCl(aq) + H2O(l)
What is too the right of the arrow in a chemical equation?
The products of a chemical reaction are typically written to the right of the arrow in a chemical equation. This section represents the substances that are formed as a result of the reaction taking place.
What is meant by skeletal chemical equation?
A skeletal chemical equation is a simplified version of a chemical equation that omits details about the physical state of the reactants and products, as well as the coefficients of the compounds involved. It focuses on showing only the essential elements and their ratios in the reaction.
What is the chemical equation of ocean acidification?
Ocean acidification is caused by the absorption of carbon dioxide by seawater, leading to the formation of carbonic acid. The chemical equation for this process is: CO2 + H2O -> H2CO3 This reaction increases the concentration of hydrogen ions in the water, lowering the pH and making the ocean more acidic.
What is true about all chemical equations?
All chemical equations must satisfy the law of conservation of mass, meaning the number of atoms of each element must be the same on both sides of the equation. Additionally, the equation must represent a balanced reaction, with equal numbers of each type of atom on both sides.
Why mole concept is used in balancing chemical equation?
mole concept is used in balancing chemical reaction because for balancing a reaction u cant change the numbers such as 1,2,3 etc.. in between the compund so as a whole we are changing outside the compound
A double arrow in a chemical equation represents a reversible reaction, meaning that the reaction can occur in both the forward and reverse directions. It signifies that the reaction can reach equilibrium where the rate of the forward reaction equals the rate of the reverse reaction.
