A high-altitude cloud made up of smaller clouds is a cirrocumulus cloud
Answer:
Spain was in debt from wars and Isabella and Ferdinand turned away Christopher Columbus's ideas of venturing/trading outside of Afro-Eurasia but once he promised to bring back riches (ie silver and gold) they granted his request and he set sail to "discover" what he thought was India but ended up in the Americas. This led to the development of 2 great trading systems: the Columbian Exchange and the Atlantic system. Things that were mostly traded were sugar, silver, and slaves (the 3 s's). Allowed Europe to venture out amongst Asian waters, which later inspired others to do the same (French, English, Dutch, etc).
Explanation:
Answer:
Explanation:
The equation for this chemical reaction is:
2Ca + O2 -> 2CaO
So 2 moles of Ca react with 1 mole of O2 to form 2 moles of CaO.
Given 3.9 moles of Ca and 2.35 moles of O2,
Ca is the greater reactant as it will be used up.
O2 is the reactant in excess and there will be 2.35 - 3.9/2 = 0.4 moles left.
As mass of 1 mole of O2 is 32g, 0.4 moles of O2 = 0.4 * 32 = 12.8g
Moles of CaO formed = moles of Ca = 3.9
As mass of 1 mole of O2 is 56g, 3.9 moles of CaO = 3.9 * 56 = 218.4g of CaO
Answer:
oil produces CO2
coal produces CO2
uranium does not produce CO2 aka nuclear reactors as this process requires dipping the uranium rods into water creating steam and turning a turbine making energy
natural gas does create CO2 but less than coal and oil that is why natural gas is preferred as a energy source
Explanation:
Answer: the entropy and entalpy of the system will increase
Explanation: adding energy to the system will cause the molecules within the jar to absorb more energy, this excitation will bring about more movement of the molecules and more collision between molecules. Also, the molecules will try to move further apart from themselves with increased degree of randomness.
