CH3CH2OH + 3O2 = 2CO2 + 3H2O

Basically you do trial and error on both sides so they can be equal

In cellular chemical pathways, the product(s) of any particular reaction are often quickly consumed by the next reaction in the
mezya [45]

Answer:

Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>

Explanation:

The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).

This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.

If you reacted 183 grams of copper sulfate with excess iron, what mass of copper would you expect to make? You may need to balan
Nezavi [6.7K]

The question does not provide the equation

Answer:-

72.89 grams

Explanation:-

The balanced chemical equation for this reaction is

CuSO4 + Fe --> FeSO4 + Cu

Molecular weight of CuSO4 = 63.55 x 1 + 32 x 1 + 16 x 4

= 159.55 gram

Atomic weight of Cu = 63.55 gram.

According to the balanced chemical equation

1 CuSO4 gives 1 Cu

∴159.55 gram of CuSO4 would give 63.55 gram of Cu.

183 gram of CuSO4 would give 63.55 x 183 / 159.55

= 72.89 grams of Cu

since butane is not found on the periodic table,how could you find the molar mass of butane(mass of one mole of butane molecules
Wittaler [7]

We know, It's atomic formula = C4H10

Now, we know molar mass of C = 12 & H=1

so, it would be: 12*4+1*10 = 48+10 = 58

Calculate thr number of photons having a wavelength of 10.0 μm required to produce 1.0 kJ of energy.
ddd [48]
Ok so first you need to figure out the energy of ONE photon with that wavelength. Using E=hc/lambda, you get E= 1.99 * 10^-20 J/photon. Now, how many photons do you need to add up to get to one kilojoule=1000 joules? 1000J / (1.99 * 10^-20 J/photon) = approximately 5 * 10^22 photons hope this helps
