<span>The answer is CFCs. The abbreviation stands for Chlorofluorocarbons. They are made by fully
halogenating paraffin hydrocarbon. These compounds are known to cause climate change damaging the ozone layer. It is,
therefore, advisable to properly dispose off of refrigerators,
solvents and propellants</span>
The statement above is FALSE.
Temperature is the degree of coldness or hotness of a body while heat transfer is the transfer of thermal energy from one object to another object. Temperature tells us how cold or hot a body is and it can be measured in Celsius, Kelvin or Fahrenheit. The thermometer is the instrument that is used in the measurement of temperature. Change in temperature is an important indicator that is used in various ways in humans and external systems.
Proton: positive- mass equal to neutron
Electron: negative- mass 1/1840 mass of proton
Neutron: no charge- same mass as proton
Answer:
You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.
without energy it wont get energy/food so it will eventually die
Explanation:
Answer: (D) 0.025 mol 
Explanation:
The given balanced equation is :
According to stoichiometry :
4 moles of ammonia 
reacts with = 5 moles of oxygen 
Thus 0.30 moles of ammonia reacts with = 
moles of oxygen
Now as given moles of oxygen are more than the required amount, oxygen is the excess reagent.
moles of oxygen left = 0.40 - 0.375 = 0.025
Thus 0.025 mol excess reagent remains.
