I'm pretty sure it's B)constructive
Answer:
Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.
Explanation:
Density = mass/volume
1. Work out the density of ethanol and benzene
Ethanol - mass = 3.9 g and volume = 5 mL
Density = mass/volume =3.9/5=0.78g/mL
Benzene - mass=4.4g and volume = 5 mL
Density = mass/volume = 4.4/5=0.88g/mL
So Benzene is more dense
2. Density=mass/volume=25/7-2=5g/mL
The reason why the volume of the object is 7mL - 2mL is because the amount of displaced water is the volume of the object
3. For the Bohr Model, google the image of it.
Protons are positive charged
Neutrons are neutral
Electrons are negative charged
4. Main difference is the location of the electron in the atom.
Bohr Model : electrons orbits the nucleus in fixed paths
Electron cloud model: only the electron's probable location is determined
Answer: The mass of NaCl required to make 140 grams of a 12% solution of NaCl in water is 17 g.
Explanation:
Given: Mass of solution = 140 g
Mass percent = 12%
Formula used to calculate grams of solute are as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the mass of NaCl required to make 140 grams of a 12% solution of NaCl in water is 17 g.
