D.The sun does not rotate
Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3
Answer:
TABLE OF CONJUGATE ACID-BASE PAIRS Acid BaseK a (25oC) HClO 4ClO 4 – H 2 SO 4HSO 4 – HCl Cl– HNO 3NO 3 – H 3 O +H 2 O H 2 CrO 4HCrO 4 –1.8 x 10–1
Explanation:
Answer : The correct option is, 0.21 moles
Solution : Given,
Molarity of the solution = 0.85 M = 0.85 mole/L
Volume of solution = 250 ml = 0.25 L 
Molarity : It is defined as the number of moles of solute present in one liter of the solution.
Formula used :
Now put all the given values in this formula, we get the moles of solute of the solution.
Therefore, the moles of solute is, 0.21 moles
Answer:
HOCH₂CH₂CH₂OH Propane-1,3-diol
Explanation:
The boiling point of compound depends up on Hydrogen bonding and vander wall forces. The C option that is alcohol will have higest boiling point assuming that the mass is approximately same (between 60-80) and the boiling point is hight because this is due to extensive intra molecular hydrogen bonding in alcohol .Hence due to hydrogen bonding the molecules are packed close and that increases the boiling point of the molecule.The Answer is option C.
HOCH₂CH₂CH₂OH > CH₃CH₂CH₂CH₂OH > CH₃CH₂CH₂CH₂CH₃ > CH₃CH₂CH₂CH₂CH₃ > CH₃CH₂CH₂OCH₃
