Sofia is trying to find the density of a 25.0 g irregularly shaped solid. She filled a graduated cylinder with 25.0 mL of water.

After adding the solid the water rises to 56.5 mL. What is the density of the solid? Does this solid float or sink in water

The volume of the solid is
56.5 ml - 25 ml = 31.5 ml
The mass of the solid = 25g
So the density is Mass/ Volume
25/ 31.5 = 0.79 g/ml

Since the solid has a lower density (0.79 g/ml) than the density of water (1g/ml) it will float on water

Answer:  Density:  0.794 g/ml.  It would float.

Explanation:  The mass of 25.0 grams displaces (56.5 - 25.0) = 31.5 ml of water, it's volume (when submerged).  Density is mass per unit volume:

25.0 grams/31.5 ml = 0.794 g/ml

Water's density is 1 g/ml, so this obect would float.  (Don't ask me why it displaced 31.5 ml.  It won't unless it is pushed down, then the volume of the finger needs to be determined and subtracted from the calculated volume.

Compare rutherford's expected outcome of the gold-foil experiment with the actual outcome.
iragen [17]
Rutherford was one of the early scientists who worked on the atomic model. Before his discovery of the nucleus, the widely accepted theory was J.J Thomson's Plum Pudding Model. In this model, all the protons, electrons and neutrons are in the nucleus. But the electrons are more in number such that the electrons act as the 'pudding' and the proton and nucleus the 'plum'. This was Rutherford's hypothesis in his gold foil experiment. In order to test the Plum Pudding model, he hypothesized that when a beam of light is aimed at the atom, it would not diffract because the charges in the nucleus are well-distributed. However, his experiment disproved Thomson's model. Some light indeed passed through but a few was diffracted back to the source. He concluded that this was because there is a dense mass inside the atom called nucleus. Thus, from there on, he proposed the model that the electrons are orbiting around the nucleus.

Which of the following statements is true?
Lera25 [3.4K]

The  statement  which is true is

metals  lose  electrons  to become cations

<u><em>Explanation</em></u>

  • metals tends  to loss electrons to attain  noble gas  electrons  configuration.
  • When metal loses electrons they form a  positive charged ions.
  • The positively charged ion is known as  cations.
  • for  example  sodium metal (Na)  loses  1 electron to form   a cation with  a charge  of positive 1 ( Na^+)

A bike lost 20% of its value after the first year, its value after the first year is $1039. Calculate the original price of the
musickatia [10]

Answer:

$1246.90

Explanation:

Since the bike lost 20%% of it's value and it now currently at $$1039, we have to do 20% * $1039 to find the amount of money lost. 20%*1039=207.8. We have to add it up to find the original value so 1039+207.8=$1246.8
