According to ideal gas equation, 0.5186 moles of gas are required to occupy 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.
<h3>What is ideal gas equation?</h3>
The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.
Substituting the given values in the given equation, n= 5.4×210/8.314×263=0.5186 moles
Thus there are 0.5186 moles occupying 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

Answer:
876 grams
Explanation:
Convert specific gravity to density, using water density 1.0 g/ml
d = e.g x 1.0 g/ml = 1.168 g/ml
d = m/v (mass/volume)
m = dxv = 1.168 g/ml x 750 ml = 876 grams
A weak acid ionizes or dissociates less producing fewer positive (H+) ions than a STRONG base does because it is supposed to disassociate more fully. So when the acid and base neutralize, not all of the OH- ions are neutralized because fewer H+ were produced than OH-.
Answer:
Bacteria
Explanation:
Eukaryotic cells have membrane-bound organelles and eukaryotic cells have a nucleus that contains the genetic material.
examples: plants, fungi, and animals.
prokaryotic cells they do have a membrane-bound organelles,nucleus is absent and their genetic material free and floating is present in the nucleoid region.
