The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.

<h3>What is Thomson “plum-pudding” model?</h3>

This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.

The nucleus contains protons and neutrons instead thereby making it the correct choice.

The options include the following:

a.The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct.

b.The Rutherford experiment was useful in determining the nuclear charge on the atom.

c.Milikan’s oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.

d.The electric discharge tube proved that electrons have a negative charge

The burning of a sample of propane
r-ruslan [8.4K]

Answer:

70.0°C

Explanation:

We are given;

  • Amount of heat generated by propane as 104.6 kJ or 104600 Joules
  • Mass of water is 500 g
  • Initial temperature as 20.0 ° C

We are required to determine the final temperature of water;

Taking the initial temperature is x°C

We know that the specific heat of water is 4.18 J/g°C

Quantity of heat = Mass × specific heat × change in temperature

In this case;

Change in temp =(x-20)° C

Therefore;

104600 J = 500 g × 4.18 J/g°C × (x-20)

104600 J = 2090x -41800

146400 = 2090 x

  x = 70.0479

     =70.0 °C

Thus, the final temperature of water is 70.0°C

Tom [10]

Molar mass of vitamin B1, C12H17N4OS = 265.34 g/ mol

Molar mass of vitamin B2, C17H20N4O6 = 376.37 g/ mol

Molar mass of vitamin B5, C9H17NO5 = 219.24 g/ mol

Molar mass of vitamin B6, C8H11NO3 = 169.18 g/ mol

Molar mass of vitamin B7, C10H16N2O3S = 244.31 g/ mol

Now,

Order of increasing molar mass = B6 < B5 < B7 < B1 < B2

#12 please! worth 40 points
Serga [27]
Okay so because of the difference in density a simple method for telling the difference between the two is to put a sample in a container with oil, because water has a higher density than the oil it would sink to the bottom but alcohol on the other hand is lighter than oil and would float on top of the oil.

However with this question I think that what you would do is use the ice to find out what the substance is, it would float on top of the liquid if it were water because the water is denser than ice but the ice would sink if it was alcohol because the alcohol is less dense than ice. 


I hope this helps you, good luck : )
