Answer:
Explanation:
<em>First calculate how many moles of O2 you have. O is 16g/mole, so O2 is 32g/mole. 50/32 = 1.5625 moles. 1 mole of any gas at stp is 22.4 liters.</em>
<em>1.5625 × 22.4 = 35 liters.</em>

Answer:
True
Explanation:
To begin with,
Hydrogen bonds are attractions that contain a force caused by the difference in charge. This is due to the positive hydrogen ions as well as slightly negative ions. Therefore, hydrogen bonds make water molecules 'sticky.' To add, the attractions between hydrogen bonds are weaker than ionic and covalent bonds but strong enough to cause them to 'stick together'
Hope this helps.
