Answer:
24.1g of chlorine & 15.6g of sodium
Explanation:
according to the law of conservation of mass
Na+Cl=NaCl only
the correct answer is A.
Each atom has three sub particles, which are electron, proton and neutron. To get the atomic mass for each atom, one has to add the masses of the proton, neutron and electron in an atom. For each atom, the major contributors to its mass are proton and neutron, this is because the mass of the electron is very small indeed. Thus, the atomic mass of an element is usually in the range of its mass number, which is obtained by the summation of proton and neutron. Since it is the number of proton that indicate an atomic number and it is the mass number that indicate atomic mass, therefore, atomic mass can be greater than the atomic number.
Explanation:
Structural formula of propene
molecular formula = C₃H₆
molecular mass = 12×3+1×6 = 36+6 = 42
no. of double bond = 1
All atomic elements consist of a positively charged nucleus surrounded by a cloud of negatively charged electrons. When two atoms of the same element have different numbers of neutrons and therefore a different atomic mass they are known as isotopes of the given element. An example of an isotope is deuterium, which is an isotope of hydrogen.
<span>You can just swab the numbers and get the answer. The answer is: Phosphorus has three unpaired electrons and hydrogen has one unpaired electron this means that three equivalents of hydrogen can react with one equivalents of phosphorus.</span>
