When the barometer rises it means air pressure goes up. When that happens there is clear skies and little clouds. So you would be expecting hotter weather.
Answer:
James Chadwick conducted an experiment where he assailed the element Beryllium with alpha particles that came from the radioactive decay of Polunium. The experiment results showed highly penetrating radiation emitted from the Beryllium. In this, Chadwick proposed that radiation consisted of uncharged particles, which were later founded as neutrons.
Molar volume means that 1 mol of any gas occupies a volume of 22.4 L at standard temperature and pressure conditions.
the molar mass of Ar is 40 g/mol
this means that a mass of 40 g occupies a volume of 22.4 L
therefore a mass of 120 g of Ar occupies a volume of - 22.4 L / 40 x 120
therefore volume occupied by Ar - 67.2 L
Both carbon 12 and carbon 14 have the same no. of Electrons but the difference is carbon 14 has more neutrons
Answer:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals. To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
