What is the word equation for hydrochloric plus acid tin?

I think you have mixed your English grammar.

The question should read 'Hydrochloric Acid plus Tin'.

What is the symbol equation for ethanoic acid plus ammonium carbonate?

2CH3COOH + (NH4)2CO3 = 2CH3COONH4 + H2O + CO2

Remember this is an acid plus carbonate reaction. The result is the salt (ammonium ethanoate (acetate), water abd carbon dioxide.

What is the result for ethanoic acid plus vinegar?

Nothing. Because you are mixing two of the same together.

Vinegar is the 'everyday ' name for ethanoic (Acetic) acid.

What is the molar mass of ethanoic acid?

Ethanoic acid has the formula CH3COOH

From the Periodic Table.

C x 2 = 12 x 2 = 24

H x 4 = 1 x 4 = 4

O x 2 = 16 x 2 = 32

24 + 4 + 32 = 60 is the Mr (

Remember the equation.

moles = mass(g) / Mr (Mr = Relative molecular mass).

Algebraically rearranging

mass(g) = moles X Mr

For 1 mole.

mass = 1 moles X 60 = 60 g/mole (The molar Mass).

Sodium carbonate acid or base?

Sodium Carbonate is neither an acid nor a base.. It is a Chemical Salt.

Chemical salts are of trhe form 'Metal ion and acidic anion'.

What is the pH of a alkaline?

The pH of any alkaline solution is between 8 and 14.

pH = 7 is neutrality (Water)

pH < 7 is acidic

What does acid and base equals?

A SALT & WATER.,

Remember the general reaction eq;ns for acids.

Acid + Base = Salt +Water

Acid + Alkali = Salt + Water

Acid + Metal = Salt + Hydrogen

Acid + Carbonate = Salt + Water + Carbon Dioxide.

NB A Salt is a CHEMICAL Salt , Not table salt.

NNB An Alkali is a soluble Base.

Here are examples of each in turn

2HCl + CaO = CaCl2 + H2O

H2SO4 + 2NaOH = Na2SO4 + 2H2O

2HNO3 + Ca = Ca(NO3)2 + H2

2CH3COOH + Na2CO3 = 2CH3COONa + H2O + CO2

A substance with a pH of 5?

A substance with a pH of 5 is considered acidic. pH is a measure of the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity. A pH of 5 means the solution has a higher concentration of hydrogen ions compared to a neutral solution with a pH of 7.

Why dilute sulphuric acid is preferred while testing anions over dilute HCl?

Dilute sulfuric acid is preferred over dilute hydrochloric acid when testing for anions because sulfuric acid is a stronger acid than hydrochloric acid. This means that it can effectively displace weaker acids from their salts, allowing for more accurate identification of the anions present. Additionally, sulfuric acid can form insoluble precipitates with certain anions, aiding in their detection through visual observation. Finally, the use of sulfuric acid minimizes the interference of chloride ions, which are present in hydrochloric acid, in the testing process.

Do orange peels have citric acid?

Oh, dude, you're asking if orange peels have citric acid? Yeah, they totally do! Like, oranges are known for their tangy citrus flavor, and that's all thanks to the citric acid in them. So, if you're ever in a citrusy mood, just take a bite of an orange peel... or maybe just stick to the fruit itself.

How do you Prepare Oxalic Acid from Ethylene?

Oh, dude, preparing oxalic acid from ethylene involves a series of chemical reactions that I'm sure some chemistry whiz out there can explain in detail. Basically, you start by oxidizing ethylene to ethylene glycol, then oxidize that to oxalic acid. It's like a chemistry magic show, but with less rabbits and more safety goggles.

What ester is formed when acetic acid reacts with octyl alcohol?

Ethanoic (Acetic) Acid + Octanol(Octyl alcohol) =

  Octyl Ethanoate ( Octyl Acetate).  and water . 

Here is the BALANCED reaction eq'n.

CH3COOH + CH3(CH2)6CH2OH CH3(CH2)6CH2OOCCH3 + H2O

Name three saturated and three unsaturated fatty acids?

Three examples of saturated fatty acids are palmitic acid, stearic acid, and lauric acid. These fatty acids have single bonds between carbon atoms in their hydrocarbon chains. Three examples of unsaturated fatty acids are oleic acid, linoleic acid, and arachidonic acid. These fatty acids have one or more double bonds in their hydrocarbon chains.

What is the difference between acid salt and normal salt?

Well, darling, acid salts are formed when a base reacts with an acid, resulting in a product that still has some acidic properties. Normal salts, on the other hand, are formed when an acid reacts with a base, resulting in a neutral compound. So basically, one is a sassy hybrid of an acid and a salt, while the other is just a chill neutral compound.

What do they mean when they say that concentrated nitric acid is 16 molar?

16 molar nitric acid is highly concentrated and corrosive in the extreme.

It means that in 1(one) litre of solution, there are 16 (sixteen) moles of nitric acid.

NB Under weaker solutions of nitric acid, the dissolution of copper has to be heated.

However, in 16M nitric acid , copper is readily dissolved without heating.

In the lab. take no more than 5 cm^(3) at a time, and handle it in the fume cupboard.

TREAT VERY CAREFULLY!!!!!

Have a solution of calcium hydroxide readily available in order to neutralise any spillages.

What is one reason that CO2H is normally written -COOH instead?

Oh, dude, like, the reason CO2H is usually written as -COOH is because it's more common to see carboxylic acids represented that way. It's just a convention in organic chemistry. But hey, as long as you know what it means, right? Who cares how it's written!

What happens when you mix hydrochloric acid and chlorine?

When hydrochloric acid and chlorine gas are mixed, they react to form a mixture of hydrochloric acid and chlorine gas. The reaction is as follows:

HCl + Cl2 → HCl + Cl2

This reaction is a reversible reaction, meaning that the products can react to form the original reactants. The reaction is exothermic, meaning that it releases heat energy.

What is the number of moles of NaOH required to neutralize 1 mole of H2SO4?

Well, darling, if we're talking about a 1:2 molar ratio between NaOH and H2SO4, then you'd need 2 moles of NaOH to neutralize 1 mole of H2SO4. It's all about those stoichiometry dance moves, honey. Just make sure you're not tripping over your chemical equations!

What happens when you mix an acid with alkali?

When an acid is mixed with an alkali, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The acidity of the acid decreases and the alkalinity of the alkali decreases as they react with each other.

What colour could methyl orange turn with oven cleaner?

Oh, dude, methyl orange could turn red when mixed with oven cleaner. It's like a chemistry magic show, but instead of pulling a rabbit out of a hat, you're changing colors with household chemicals. Just make sure not to accidentally turn your oven into a rainbow while cleaning it, unless you're into that sort of thing.

What is the chemical equation for magnesium carbonate and nitric acid?

Oh, dude, you're hitting me with some chemistry stuff now? Alright, fine. So, the chemical equation for magnesium carbonate reacting with nitric acid is MgCO3 + 2HNO3 → Mg(NO3)2 + H2O + CO2. There you go, science class is officially in session.

What elements are in the compound 'sulfuric acid - H2SO4'?

Sulphuric Acid (H2SO4)

Elements present

2 x H (2 atoms of hydrogen)

1 x S (1 atom of sulphur)

4 x O ( 4 atoms of oxygen).

Make up one molecule of sulphuric acid (H2SO4).

What does sulfuric acid do to limestone?

React with it.

What you may see is 'fizzing', which is the liberation of carbon dioxide from the limestone.

Limestone is an impure form of calcium carbonate(CaCO3)

Like all acid/carbonate reactions, there is the liberation of carbon dioxide and water.

Here is the balanced reaction equation.

Sulphuric Acid + Calcium carbonate(lomestone) gives calcium sulphate + water + Carbon dioxide.

H2SO4(aq) + CaCO3(s) = CaSO4(aq) + H2O(l) + CO2(g) .

NB Calcium carbonate exists in many forms ; viz: limestone, chalk, marble, egg shells, to name but a few.

What is the name given to a soluble base?

A soluble base is called an alkali. Alkalis are substances that can neutralize acids, forming salts and water. Examples of soluble bases include sodium hydroxide and potassium hydroxide.

What can't stomach acid dissolve?

Well, isn't that a fascinating question! Stomach acid is quite powerful, but there are some things it can't dissolve completely, like plastic, glass, and certain metals. It's important to remember that our bodies are amazing and have their own ways of handling different substances. Just like in painting, sometimes it's about finding the right balance and knowing what works best together.
