Sodium hydroxide react with sulfuric acids would give a warm solution

You asked a very good question Does sodium hydroxide reacting with sulfuric acid give a warm solution? Change the question, say do neutralisation reactions give warm solution? Neutralisation reactions

What is the ionization of methanol+ water

would it be CH3+ HOHC? thanks-methanol is not an acid, it shouldnt ionize in water.

I got stuck with this question about drying of puddles

so here is the question: Everyone has observed that if the sun comes out immediately after a rain shower the puddles dry up much faster than if it remains cloudy. Explain at the molecular level why th

Which 3 atoms must be removed when combining any two organic molecules

Also, could you give me examples of nonpolar molecules, like... which of these molecules are nonpolar: N2, CH4, H202, H20, CO2, O2, NH3, COOH And it would be a great help if you could tell me how to

How does chloroform work

What in it makes humans lose consciousness?-It depresses the central nervous system so your brain goes into lala land.

Which occupies the largest volume? chormium, a lead-tin alloy, bromine or sodium

25.5mol of sodium metal (d =0.971g/cm^3 ) •0.725L of liquid bromine (d = 3.12 g/mL) • 1.25 * 10^25 atoms of chromium metal (d = 9.4 g/cm^3) •2.15 kg of plumbers solder (d = 9.4 g/cm^3) a lead-tin allo

Cyanide - oxidation numbers of Carbon and Nitrogen, how to figure out

I know the lewis structure of Cyanide and that it has a -1 charge(oxidation number?)....but how would i figure out the individualoxidation numbers of Carbon and Nitrogen which are +2 and -3...i know i

Mol help? Please help me T.T

So I have a project and I have no idea what its about :( So he said we had to have a thing (for example a can of soup.Which is what I am using.)and how many of this other thing can fill it up. What

Moles is so confusing

O in moles is 16.0 grams and theres 6.02 * 10 /\23 atoms in it, but when asked for one mole of O2 ( in grams) why is it 32.0 grams because that would mean that theres 2 * 6.02 * 10 /\23 atoms in it. I

What is its molarity after a reaction time of 7.00 days

Hydrogen iodide decomposes slowly to H2 and I2 at 600K . The reaction is second order in HI and the rate constant is 9.7 x 10^-6 M^-1s^-1 . If the initial concentration of HI is 0.110 M. What is its

How do I balance this equatiom

H2S + CO -----> CH3CO2H + S8 And please explain it to me! Thanks!-The answer by M has a spurious factor of 4 in it. Heres the correct answer: Balance the H and the S at the same time: 2H2S + CO ---

Calculate the mass of a 2.4x 10 to the 4th mm3 cube of aluminum, it's density is 2.70g/cm3

Use dimensional analysis. 2.4 x 10^4 mm^3 * (1cm/10mm)^3 = 24 cm^3 24 cm^3 * 2.70 g/cm^3 = 64.8 g Al-2.4E4 mm^3 *2.70 g/cm3 * 1cm/10mm * 1cm/10mm * 1cm/10mm = 64.8g
