Chemistry problems! Please help

Methanol (CH3OH) can be produced through the reaction of carbon monoxide and hydrogen in the presence of a catalyst. If 75.0 grams of carbon monoxide reacts to produce 68.4 grams of methanol, what is

Why is Sodium chloride much soluble than silver chloride

I get how to figure out if something is soluble, but dont get how to figure out what is more soluble-It turns out that silver chloride has significant covalent bonding characteristics as opposed to Na

Why does a ball or tire gets flat when in cold environment

Gas laws-It is because temperature ans pressure are directly proportional. So as the temperature decreases, so will the pressure. PV=nRT, and if you plug in higher or lower temperature, the pressure w

What is i^55 + i^88

-i + 1

Why do balloons get smaller when they are taken from different areas

from high temperature to colder temperature gas laws-because air expands and contracts in different temperatures :) so if you take a balloon into a warm room it will expand because the air in side it

How do you know if the reaction Fe + O2 makes FeO or Fe2O3

When equation writing, should you assume that Fe + O2 will be FeO or Fe2O3? Why?-It depends on the oxidation state of the iron. Iron can exist in two oxidation states: +2 or +3. However, Iron (II) oxi

Why do oxidising agents gain electrons

This may sound reeeeeealy dumb, I know, but.. Im doing AS level Chemistry and whilst revising I came across the fact that oxidising agents gain electrons. This confused me because, take Cl for example

Percentage Yield Question

The thermite reaction has been used to weld railroad rails, make bombs, and ignite solid rocket fuel. The equation of the reaction is: Fe2O3 + 2Al --> 2Fe + Al2O3 1) What is the theoretical yield of i

If a certain type of gas sticks easily to say metal surfaces, is the gas adsorbent or adsorptive

And in that case is the metal surface adsorbent or adsorptive?-The metal will be the adsorbent and the gas the adsorptive.Look up the reference below for further clarification.

Which of the following pairs of element could react to form an ionice compund

Ca and Cl S and K Ba and Cu Cl and Br-Only CaCl, and KSform ionic compounds. Ba and Cu both have metallic properties same with Cl and Br, they both have non-metallic prperties.-Look at a periodic tab

PLEASE HELP ME!! How is the Activity Series of Metals related to single replacement reactions

I just need to know this for chemistry homework :D and also could you possibly tell me why do all chemical reactions have to be balanced? Much appreciated :D LOVE YOU TO PLUTO AND BACK :D -im pretty

Rank the following compounds by solubility in water, most soluble to least soluble

I. CH3CH2OHII.CH3OCH3III. CH3CH2NH2 a - I,II,III b - I,III,II c - II,I,III d - III,I,II e - III,II,I-Of these three items, ethanol (the first one) is the most soluble in water; it mixes in all propor

What is the reaction for hydrogen phosphate and potassium hydroxide

i have tried putting it together but i cant figure it out.-K2HPO4 + KOH ---> K3PO4 + H2O Its an acid-base neutralization and the products are a salt and water.-is it a double replacement reaction. if
