Answer:
d. All of the above three answers are correct
Explanation:
Atoms are themselves built up from many smaller particles. According to Rutherford's nuclear theory (1906), the neutron and proton make up the nucleus of the atom. Atoms are electrically neutral because they contain the same number of electrons and protons. The size of atoms is about 
meters. The fundamental particle of the atom is the electron.
Answer:
1.) The result is a red solution and a blue-green precipitate.
2.) The reaction results in a precipitate of a basic salt, which can co-precipitate with other metal ions that form hydroxide precipitates, causing complications when trying to separate metal ions.
Answer:
The answer is
<h2>1.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 10 cm³
It's density is
We have the final answer as
<h3>1.0 g/cm³</h3>
Hope this helps you
Answer:
Explanation:
so u can work out the amount of moles of S8 by using
moles=mass/mr
=16/32.1=0.498moles
then use the molar ratio of
S : Fe
1:1 so the moles of Fe is the same 0.498
The use the equation
mass = mr x moles
=55.8 x 0.498
=27.78
so 27.8 g
hope this make sense :)
Regretfully, I do not know what is asked of the problem because it is not stated above. However, it is easier to answer any question pertaining to the temperature, volume, and pressure of gases by assuming that they behave ideally. With this, we'll be able to use the ideal gas law which is mathematically expressed as,
PV = nRT
where P and V are pressure and volume, respectively. n is the amount of material in mol, R is gas constant, and T is temperature.
