Answer:
sun, air, water, wind and ocean current
Explanation:
As sun is the major source of energy on earth, the earth gets heated due to solar energy, this creates convection currents in the Air and Water, the heating of these areas create wind and ocean currents due to difference in temperature and pressure.
Answer:
367.7 mL
Explanation:
V2=P1V1/P2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
The mass of C₂H₂ that would be produced by complete reaction of 3.75 g of calcium carbide is 1.524 grams
<u><em>calculation</em></u>
calcium carbide (CaC₂) react with water(H₂O) to produce C₂H₂ and Ca(OH)₂ according to reaction below
CaC₂ +2H₂O C₂H₂ + Ca(OH)₂
calculate the moles of CaC₂
moles = mass÷ molar mass
from periodic table the molar mass of CaC₂ = 40 + (12 x2) = 64 g/mol
moles is therefore =3.75 g÷ 64 g/mol =0.0586 moles
Use the mole ratio to determine the moles of C₂H₂
from equation above CaC₂: C₂H₂ is 1:1 therefore the moles of C₂H₂ is also
= 0.0586 moles
mass of C₂H₂ = moles x molar mass
from periodic table the molar mass of C₂H₂ = (12 x 2) + (1 x 2) = 26 g/mol
mass =0.0586 moles x 26 g/mol =1.524 grams
