Explanation:
Hello there!
In this case, according to the given data, it is possible to infer that the gas mixture lies on the 15.0 cm-high column of water, so that the total pressure or atmospheric pressure is given by:
Thus, since the atmospheric pressure is 745 mmHg and the vapor pressure of water is 18 mmHg, the pressure of hydrogen turns out to be:
Best regards!
The relative atomic mass is the weighted average mass of elements relative to 1/12th the mass of a 12-C atom.
Isotopes are atoms of the same element with different masses , in other words different numbers of neutrons.
Relative atomic mass =sum of (mass x percentage )
R.a.m = 62.9300 x 69.15% + 64.9200 x 30.85%
= 43.52 + 20.03
= 63.55 amu
The volume will decrease, because as the temperature is lowered, the atoms will move slowler and they won't fill as much the balloon
primarily ionic include = sodium iodide( NaI) , calcium chloride ( CaCl2)
primarily covalent include - Ammonia (NH3) , Methane ( CH4) and
Glucose (C6H12O6)
Explanation
ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.
for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.
Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.
For example in NH3 3 pairs of electron are shared. to form covalent bond.
