I believe the answer is orbital hybridization theory
Answer: 37.5grams of Cu(NO3)2
Cu(1mol) + 2HNO3(2mol) —> Cu(NO3)2 + H2
<em>125 grams of Cu(1mol) reacts with 75 grams of HNO3(2mol)</em>
<em><u>HNO3 is the limiting substance, therefore, 75 grams is the limiting quantity.</u></em>
<em>Therefore, 2mol of HNO3 forms 1mol of Cu(NO3)2</em>
<em>75 grams of HNO3 forms...75grams x 1mol/2mol = 37.5 grams of Cu(NO3)2</em>
Answer:
Constellations Changing Positions!!!! :D <----(smiley face)
Explanation:
Due to the earth's rotation, stars appear to move. As the Earth rotates from west to east, the stars appear to rise in the East, moving across south to set in the west. The Sun will appear to move through the stars, making one complete circuit of the sky in 365 days!!
(yes i'm literally 9+6 years old and idek why i'm doing this XD )
The grams of carbon dioxide that are in 35.6 liters of Co2 is calculates as below
calculate the number of moles of CO2
At STP 1 mole = 22.4 L
what about 35.6 liters
= 1mole x 35.6 liters/ 22.4 liters = 1.589 moles
mass of CO2 = moles x molar mass of CO2
= 1.589 mol x 44 g/mol = 69.92 grams
A: 12 N
B: 150 N
C: 100 N
D: 150 N
E: 220 N
