Answer is: Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.
Rutherford theorized that atoms have their charge concentrated in a very small nucleus.
This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model, because it shows that most of the atom is empty space.
Answer:
=final temperature
Explanation:
In the question specific heat of water is not given but we should know the value of that and it 4.18Jg∘C
Specific heat means how much heat is required to increase the temperature of 1 gram of substance that substance by 1∘C .
Equation between heat lost or gain and the change in temperature.
q=m⋅c⋅ΔT , where
q - the amount of heat
m - the mass of the sample
c - specific heat of sample
ΔT - change in temperature
put all the given value into this ,
=final temperature.
Steriods belong to the class of lipids which contains four carbon rings that are fused. Examples of these are estradiol and testosterone. They are important in cell membranes since they are responsible in altering membrane fluidity and also they are molecules used in signaling.
6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.
