3. bromine has 2 types of atoms: 79/35 Br and 81/35 Br. What is the difference between the 2 atoms?
Jawaban:
There are isotopes
Penjelasan:
isotopes are atoms that have the same number of protons and electrons but different numbers of neutrons anda the are have different physical properties
79/35 Br = number of e- 35 , protons 35 , and neutron 44
81/35 Br = number of e- 35 , protons 35 , and neutron 46

4. The mass of a carbon atom is 2*10^-27g How many carbon atoms are there in 6g of carbon
Answer:
The mass of one carbon atom is 210^-27g, so to find the number of carbon atoms in 6g of carbon, you would divide 6 by 210^-27.
6g / (210^-27g) = 310^26 atoms
There are 3*10^26 carbon atoms in 6g of carbon.
step-by-step breakdown of how to find the number of carbon atoms in 6 grams of carbon:
Write out the given information: the mass of one carbon atom is 2*10^-27g, and you want to find the number of carbon atoms in 6g of carbon.To find the number of atoms, you need to divide the mass of the sample (6g) by the mass of one atom (2*10^-27g).So, set up the equation: 6g / (2*10^-27g) = x (where x is the number of atoms).Solve the equation: 6 / (210^-27) = 310^26 atomsThe final answer is: 3*10^26 atoms.

6. Soal Gold foil (d = 19300 [kg/m^3] with an area of 14.5 [cm 2] has a mass of 1.93[mg] a) what is the volume of the 1.93 (mg) gold? b) determine the thickness of the gold foil expressed in angstroms if i Ao = 10 - 10 [m] c) the atomic diameter of gold is = 5 Ao, if the thickness of the paper is expressed in gold atoms, then how many 'atoms' is the paper thick? 1. An object of 8.0 [kg] is suspended from the end of a metal wire that is 75 [cm] long and 0.130 (cm) in diameter. Due to the load the wire extends by 0.035 [cm]. Determine the stress, strain and modulus of elasticity in the wire. 2. For laminar flow in problem number 4 with a pipe diameter of 25cm flow velocity is 3.84 x 10-4 m/s and dynamic viscosity 7.87 x 10) (-3) m's produces a pressure drop of 0.161 Pa. However, in the real world, the flow velocity is very small. If we assume the flow velocity in daily life is 1 m/s, then what is the pressure drop? 3.

7. what number of Fe atoms and what amount (moles) of Fe atoms are in 500.0 g of iron
STOICHIOMETRY :
It is known that the mass of Fe (Iron) we have is 500.0g and if we open the periodic table, it is also told that the relative atomic mass (Ar) is equal to approximately 56. So in this case we can find the mole of the iron with :
[tex]n = \frac{m}{Ar/Mr}[/tex]
Where :
n = mole
Ar/Mr = Relative Atomic Mass / Relative Molecular Mass
m = mass
So..
[tex]n = \frac{500}{56} = 8.92 ≈ 9 moles[/tex]
So the answer is 8,92 moles of Fe or approximately 9 moles of Fe
Hope it helps, Shalom!

14. what can be said about all the atoms in an elements
I can said
Atoms are a basic unit of matter, composed of atomic nuclei and the negatively charged cloud of electrons that surround it. The atomic nucleus consists of a positively charged proton, and neutrons are neutrally charged (except in the nucleus of Hydrogen-1 atom, which has no neutrons). The electrons in an atom are bound to the nucleus of an atom by an electromagnetic force. Such a set of atoms can bind to each other, and form a molecule. Atoms containing the same number of protons and electrons are neutral, while those containing different numbers of protons and electrons are positive or negative and are called ions. Atoms are grouped according to the number of protons and neutrons found in the nucleus of the atom. The number of protons on the atom determines the chemical element of the atom, and the number of neutrons determines the isotope of the element.
