Answer:
Volume of flask = 29.134 cm³
Explanation:
Mass of water = mass of filled stoppered flask - mass of empty stoppered flask.
Mass of water = 65.858 - 36.724 = 29.134 g
Density of water = 1 g/cm³
Volume = mass/ density
Volumeof water = 29.134 g/ 1g/cm³ = 29.134cm³
Therefore, volume of flask = 29.134 cm³
Answer:
They're different - heat and thermal energy. ... The heat, in turn, speeds up the molecules within the pot and the water. If you place a thermometer in the water, as the water heats up, you can watch the temperature rise. Again, an increase in internal energy will result in an increase in temperature.
I feel like it would be O.40 mol Mgo but I could be wrong
It depends if the zinc ion lost or gained an electron. But electrons are more than 2,000 times smaller than a proton or neutron so small diffrence.
