Answer:
6.791
Explanation:
For proper significant figures with addition, you would use the significant figures of the number with lowest decimal place. 6.298 goes to the 10⁻³ place. 0.492712 goes to the 10⁻⁶ place. You will go out to the 10⁻³ place.
6.298 + 0.492712 = 6.790712 ≈ 6.791
Avagadros law states that volume of gas is directly proportional to number of moles of gas at constant pressure and temperature.
where V -volume , n - number of moles
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting these values in the equation
V = 44.8 L
answer is C. 44.8 L
Answer: The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system—as well as all the other systems—need nutrients and must get rid of metabolic wastes.
Explanation:
Answer:
C) differ in the arrangement of their atoms about a double bond
Explanation:
Cis-trans isomers -
Isomers are the molecules which have the same molecular formula but they differ in their arrangement of atoms.
The two isomers possible are the cis and the trans isomer .
1. Cis - isomer - The priority group or the similar group are at same side of the double bond .
2. trans - isomer - The priority group or the similar group are at different side of the double bond . ( the group are diagonally present )
Hence , the option about cis - trans isomer is ( c ) .
<span>H2SO4 gives 2 moles oh H+ per mole of acid
[H2SO4] = 2M so [H+] = 4M
pH = -log(4) = -.6
Therefore, the pH </span><span>of a 2.0 M H2SO4 solution is -0.6
