2 boxes of A
Because C = A + B
2 of A = 20 grams
at the other hand we have 2 of B = 10
So 20 + 10 = 30 grams
Answer: In creating a covalent bond, it would be best to bind oxygen to carbon (C ).
Covalent bonds result from electron-sharing between two atoms. One carbon atom combines with two oxygen atoms. Thus, the carbon dioxide molecule has two C=O bonds. Carbon dioxide is a very common covalent bond.
Answer:a) 0.1 mole. b) 4g. c) 2% d) 196 mL
Explanation: in 200mL , 0.1mole
mw NaOH = 40g/mol —> 4g in 0.1 mole
4g in 200mL so 2g in 100mL
density NaOH = 1g/mL so if 4g in 200 mL, 4mL , 196 mL water
Answer:
The pressure inside the container will increase by increasing the amount of gas.
Explanation:
It can be better understand through ideal gas equation,
PV = nRT
By keeping the volume and temperature constant, the pressure of gas in container will increase when amount of gas goes to increase.
PV = nRT
P = nRT / V
P = (1+ 14) RT/V
P = 15
The pressure will increase 15 fold.
Neptune has the strongest winds in the solar system. with speeds up to more than 1,200 mph (2,000kph). those speeds are close to the top speed of U.S. Navy F/A-18 Hornet fighter jet !
