Answer:
Topographic maps generally shows Natural features such as Rivers and Lakes.
sometimes they also show some features made by humans like brodges, elevations etc.
transmutation. the conversion of an atom of one element to an atom of another element
Answer
is: mass number stays 184, but atomic number changes.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from an atomic
nucleus.
There are two types of beta
decay: beta minus and beta
plus. In beta minus decay (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.
Answer:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).
Explanation:
Hope it helps!
Answer:
Metal name (charge in roman numerals) Non metal
for example Iron (III) chloride
Explanation:
The rule for naming special transition metal are as follows -
a) First name the transition metal
b) Now write the name of the non metal in the chemical formula.
c) Write the charge for the non metal.
d) If there is a polyatomic ion, write the Common Ion Table ,its formula and charge.
e) Based on the total charge on the non-metal or polyatomic ion, deduce the total charge on the transition metal
f) Write the charge of transition metal after the name of metal in Roman Numeral in parentheses
