Write an equation for the reaction with an excess of H2. Give all possible isomeric products. I see the most obvious isomer adding a total of 6 H's (due to the equation) and getting rid of the double bonds but I don't understand how to get the other 3 isomers. I know that there are a total of...

I always wanted to know how the temperature inside a furnace or a reaction is measured. For eg in my textbook it is given that temperature inside a lime kiln is 1273K. how did they ever find it out? Do they have huge thermometres.

Hello, I just need some help on these questions and some explaining. I need help writing the condensed word equation for these chemical equations: A) Li + Hg(ClO)_2 \xrightarrow~Hg + LiClO Maybe: Lithium + Mercury(II) Chlorine oxide ------> Lithium Carbonate B) C_8H_1_8 + O_2...

Hello, I just need some help on these questions and some explaining. What to do: > Balance each of the following chemical equations. > Identify the type of chemical reaction (Decompostion, Combustion and Synthesis) > Write the condensed word equation A) Li + Hg(ClO)_2 \xrightarrow~Hg...

Take this double replacement reaction for example: Na_2SO_4 + CaCl_2 How am I supposed to tell whether the product will be CaSO_4 + Na_2Cl_2 or CaSO_4 + 2NaCl? Obviously, there's a difference between Calcium Sulfate + 2 Sodium Chloride molecules and Calcium Sulfate + Sodium DiChloride...

Outer shells and reactions... We say that atoms react in order to gain full outer shells - but why do they do this? Let's take water as an example - oxygen is very electronegative, so much so that when an oxygen atom collides with a hydrogen atom the outer electron of the hydrogen starts to...

Condensation reactions occur between the OH and H of C 1,4 and 6 to form polysaccharides - why do we not get reaction at C 2 or 3? ( 5 is obvious since it is not attached to H or OH ) Thanks. :smile:

Kevin Sites, the reporter present at the killing in the Fallujah mosque, has written an account of his experience that day as an 'Open Letter to Devil Dogs of the 3.1'. The Middle East scholar who goes by 'Abu Aardvark' comments on how the current absence of al-Jazeera in Iraq affects public...

general "quantities in chemical reactions" questions hi, im in high school, and we are currently doing a unit of chemistry on quantities in chemical reactions, and there are a few things i don't get, and i was wondering if anyone could show me a formula or an example, on calculating the...

I'm reviewing for a test and having a bit of trouble fully understanding the free-radical chain reactions and writing the mechanisms (initiation, propagation and termination) steps. For example, my book describes the mechanism for chlorination of methane and I just don't follow it very well...

Here's another I want to just check with you The pH of 0.01M Methylammonium chloride (not from the last thread)is lower than 7, correct? As Methylammonium is a weak base and HCl a strong acid? The pH of potassium cyanide will 7? Both KOH and HCN are very strong? And finally, the pH of...

I feel like an idiot asking this in a chemistry forum, but I have looked everywhere. I don't understand what acid and bases are, and how they work. I understand chemical bonding down to quantum physics, but I just don't understand this, what is happening in an acid?

Hi I got two questions regarding the following chemical: i) P_4 + 5O_2 -----> P_4 O_10 ii) P_4 O_10 + 6H_2O -----> 4H3 PO_4 How many grams of P_4 O_10 are formed in i) if there is 35 grams of P_4 ?? How many grams of H_3 PO_10 are formed in ii) if I have 35 grams of P_4 ...

In layman terms could you guys try to explain how a nuclear reaction works?

A Rule of Thumb: "Higher Electronegativity seeks bonding with Lower Electronegativity" Before completing my PhD in organic chemistry, with a minor in inorganic, some 20 yrs ago, I realized that the main mechanism for most organic reactions and most inorganic reactions was one of negative...

i am having problems figuring out how to resolve the moments can someone help me please Determine the reactions at "A" and "B" A is a moving support B is a fixed support please check attached file for problem

Don't know if this is even the right place for this, but reading Popular Science? i think... anyway, they mentioned the fact that if you bombard Hafnium 178 with x-ray radiation, you get about a 50-60 fold return in gamma radiation. I don't know where to classify that...nuclear reaction? but it...

KBrO2 + KI + HBr ---> KBr + I2 + H2O eq1 KBrO2 ---> KBr 4e- + 4H+ +KBrO2 ---> KBr + 2H2O eq2 2KI ---> I2 + 2K+ + 2e- 4KI ---> 2I2 + 4K+ + 4e- eq3 HBr ---> KBr K+ + HBr ---> KBr + H+ since the charges in eq3 are +1=+1 you don't have to multiply this equation by 4 do you...

I have a problem on my homework that lists several different reactions involving K mesons and asks which of them can happen via the strong interaction. I've listed a couple of them below, and I'm hoping that someone can tell me why these can or can't proceed via the strong interaction: (K-)...

i attached a picture of what it looks like. I am supposed to find the reactions at c & d, and the reactions at a & c. i think its supposed to be done using a 2 force system. i have no clue how to even start this.

LaTex help for nuclear reactions? - got it, thanks i need a guideline for to get images for nuclear equations, all my attempts thus far were failures. i tried ^4_2 He + ^27_13 Al becomes ^31_15 P becomes ^30_15 P + ^1_0 n , but it didn't work. i don't know why, nor do i have the time to...

I was just wondering, and it probably isn't a great, extreme complex question - But does alcohol contain a high or low enzyme reaction rate activity? I know that amylase is not a starch because it comes out negative for Iodine; I know that amylase is not a sugar because it tests negative for...

Looking at the table of isotopic masses table it seems that certain atoms, as 64Zn or 58Ni, could be able to capture an electron and then release a positron with an energy higher, in average, that the initial electron. On the other side, some nucleus are able to capture a positron and release...

I'm having trouble with sample AP Equation writing questions such as; solid zinc hydroxide is treated with concentrated sodium hydroxide solution. The sheet my teacher provided does not cover this reaction and many others is there any material out there that tells what will happen in most reactions

I don't know how to solve this problem... well here it goes... 33Cl(n,?)31p this is what I did... 33 (1) 31 4 17 Cl + 2(0)n -----> 15 P + 2 He Is this right ?
