Moles are made up of melanocytes. Which are located on the outer layer of skin. Different people have different color moles, an African-American could have a pink mole, and on the other hand (get it other hand hehehe) a Pacific Islander could have a really dark brown mole. Sometimes,a cluster of melanocytes forms and they form a ,yup you guessed it ,a mole! It is important to get checked for skin cancer if you have a series of moles or freckles pop up in a short period of time. Any race can get skin cancer, so wear sunscreen!Always wear sunsreen!
Molecules. Geddit? Mole-cules?
Bwahahaa...
Anyways, yeah a mole is basically just a collection of skin cells called melanocytes that are responsible for skin pigmentation. When these cluster it forms a mole. We're actually all born with all the moles we'll ever have, but some only darken and become apparent as we age.
Hope that helps somewhat :)
1 mol is equal to the molar mass of a compound expressed in grams.
1,4 moles of lead(II) oxide are formed.
2Mg + O2 -----> 2MgO So two moles of magnesium oxide are formed if x moles of magnesium are allowed to react with only 1 mole of oxygen molecules. The oxygen has become the limiting ingredient.
The answer is 8 moles CO2.
One mole of oxygen is 32 g.
3,44 moles H2 react with 1,146 moles NH3. The limiting reactant is hydrogen. O,244 moles N2 remain. 19,5 g NH3 are obtained.
Also 0,3 moles nitric oxide.
4 moles
When methane undergoes complete combustion, the equation for the reaction is CH4 + 2 O2 -> CO2 + 2 H2O. This shows that the number of moles of carbon dioxide formed are the same as the number of moles of methane reacted, so that 14 moles of carbon dioxide will be formed from 14 moles of methane.
Balanced equation. 3NO2 + H2O -> 2HNO3 + NO 8.44 moles NO2 (1 mole NO/3 moles NO2) = 2.81 moles NO formed
1.4 moles - the HCl is the limiting ingredient
2H2 + O2 --> 2H2OAs you can see by the balanced reaction, for every 1 mole of oxygen used, 2 moles of water are formed. Also notice that for every 1 mole of oxygen used, you need 2 moles of hydrogen to produce the 2 moles of water. So in your case 110 moles of oxygen would produce 220 moles of water & would also require 220 moles of hydrogen (which you have in excess since you have 230 moles of hydrogen). So 220 moles of water are the most that can be formed.
1,4 moles of lead(II) oxide are formed.
The most straightforward reaction for the formation of SO3 from SO2 is 2 SO2 + O2 => 2 SO3. If this is the actual reaction for the formation, 3 moles of SO3 are formed from 3 moles of SO2.
1,5665 moles barium phosphate
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
2Mg + O2 -----> 2MgO So two moles of magnesium oxide are formed if x moles of magnesium are allowed to react with only 1 mole of oxygen molecules. The oxygen has become the limiting ingredient.
Using the molar mass of nh3, we find that we have 2.5 moles of nh3. Since 3 moles of h2o are produced per 2 moles of nh3, we see that we will produce 3.75 moles of h2o. This is equivalent to around 3.79 g.
