A 10kg bowling ball would require what force to accelerate down an alleyway at a rate of 3m/s2?
mixas84 [53]
Ok so this all boils down to Newton's second law

Force = mass X acceleration 

 so the force = 10 X 3 = 30N

Nitroglycerin (c3h5n3o9) is a powerful explosive. its decomposition may be represented by 4c3h5n3o9 → 6n2 12co2 10h2o o2 this re
professor190 [17]
The balanced chemical reaction describing this decomposition is as follows:
<span>4c3h5n3o9 .............> 6N2 + 12CO2 +10H2O + O2

From the periodic table:
mass of oxygen = 16 grams
mass of nitrogen = 14 grams
mass of hydrogen = 1 gram
mass of carbon = 12 grams
Therefore:
mass of </span><span>C3H5N3O9 = 3(12) + 5(1) + 3(14) + 9(16) = 227 grams
mass of O2 = 2(16) = 32 grams

From the balanced chemical equation:
4(227) = 908 grams of </span>C3H5N3O9 produce 32 grams of O2. Therefore, to know the amount of oxygen produced from 4.5*10^2 grams <span>C3H5N3O9, all we need to do is cross multiplication as follows:
amount of oxygen = (4.5*10^2*32) / (908) = 15.859 grams</span>

Which element will only gain one electron during a chemical reaction?
Gelneren [198K]

Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

  • Halogens have a seven electrons in their outermost shell.
  • To complete the number of electrons in this shell, they need to gain an additional electron.
  • One more electron makes the halogen similar to the corresponding noble gas which is very stable.
  • Halogens are very reactive groups of elements and are highly electronegative.
  • They have a high affinity for electrons.
  • These elements are fluorine, chlorine, bromine, iodine and Astatine.
