Answer:
Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time. ... Also, speed is a scalar quantity but velocity and acceleration are vector quantities.
Explanation:
Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
Answer:
because it may cause burn that causes acid to build up which causes you to keep having an upset stomach
Answer:
It's called the shielding effect
Explanation:
It describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. (I hope this helps)
Explanation:
Tc - 99 is technetium 99.
It is a radioactive element that decays spontaneously. It has a half-life of 211,000 years and decays to stable ruthenium.
- On the periodic table, it has an atomic number of 43;
Mass number = 99
Atomic number = number of protons = number of electrons in atom
Number of protons in Tc is 43
electron is 43
Mass number = number of protons + number of neutrons
Number of neutrons = mass number - number of protons = 99-43 = 56
