The last chemical equation doesn't follow the law of conservation because there isn't an equal number of zinc
That force is electric force of attraction.
Answer:
Explanation:
Hello,
In this case, given the molality of the solution which is 2.88 m (mol/kg) we can compute the moles of sodium hydroxide that are dissolved in the 232 grams of water (0.232 kg) as follows:
Then, by using the molar mass of sodium hydroxide we compute the grams:
Regards.
Answer:5 carbons
Explanation:
Pentane is an organic compound with the formula C5H12—that is, an alkane with five carbon atoms.
The final temperature on increasing the pressure to 7.65 atm is 637 K.
Explanation:
The relation between temperature attained by gas molecules at varying pressure is defined by Guy-Lusac's law. It states that at constant volume, the pressure experienced by the gas molecules is directly proportional to the temperature attained by those molecules.
P∝T
Here, the initial pressure P₁ is given as 4 atm at temperature T₁ = 333 K, then the final pressure P₂ = 7.65 atm can be attained at temperature T₂.
The final temperature should be greater than the initial temperature as there is an increase in the pressure.
So,
Hence, the final temperature on increasing the pressure to 7.65 atm is 637 K.
