The appropriate answer is c. It reduces pollution from runoff. Drip irrigation supplies water directly to the roots of the plants. This reduces loss of water from infiltration and evaporation. Water with nutrients is supplied directly to the roots of plants and so this reduces the chance of excess water infiltrating the soil and contaminating the ground water with pollutants.
im pretty sure, a shade of purple
Explanation:
Molar mass of is 114.23 g/mol. Therefore, its number of moles are calculated as follows.
No. of moles =
=
= 0.043 mol
So, 0.043 moles are releasing 239.5 kcal of heat. Hence, heat released by 1.54 mol will be calculated as follows.
= 8577.44 kcal
Thus, we can conclude that 8577.44 kcal heat is released by the combustion of 1.54 mol of .
Answer: Chemicals become positively charged by loosing electrons.
Explanation: There are three types of compounds:
1) Neutral compounds: These are the compounds where equal number of protons and electrons are present.
2) Positive compounds: These are the compounds where number of protons are more than the electrons. These are considered as cations.
3) Negative compounds: These are the compounds where number of electrons are more than the protons. These are considered as anions.
So, in order to have a positive charge on a compound, that compound has to loose electrons, so that the number of protons gets higher than the number of electrons.
