2. What was the primary reason in the 1850's driving the curiosity of atoms?
1905-Einstein
1827-Brown

Answers

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

What is the specific heat of a substance that absorbs 228 joules of heat when a sample of 706 g of the substance increases in tempature from 26.0 c to 88.8 c

Answers

Answer:

[tex]c=5.14\ J/kg ^{\circ} C[/tex]

Explanation:

Given that,

Heat absorbed by a sample, Q = 228 J

Mass of a sample, m = 706 g = 0.706 kg

Initial temperature is 26 °C and final temperature is 88.8°C

We need to find the heat absorbed by the sample. The heat absorbed by an object is given by :

[tex]Q=mc\Delta T\\\\\text{Where c is specific heat of sample}\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{228\ J}{0.706\ kg(88.8-26)^{\circ} C}\\\\c=5.14\ J/kg ^{\circ} C[/tex]

So, the specific heat of the sample is [tex]5.14\ J/kg ^{\circ} C[/tex].

How long will a 25.00 g
sample of americium-241
toke to decay to form a 6.25
g sample of americium-241?

Answers

Answer:

Hope it helps.

Explanation:

It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131

Heavy unstable atoms will continuously emit radiation and will undergo nuclear decay to form stable products. 25 g of americium -241 will take 39 years to decay into its 6.25 g sample.

What is radioactive decay?

Heavy unstable nuclei undergo decay when they emit radiations of alpha, beta or gamma particles. After that they will form stable isotopes or other lighter nuclei after emitting these charged particles.

The time an unstable nuclei takes to decay into half of its initial amount is called half life time. The half life time of Americium -241 is 432 years. Thus half life time of 25 g of Am-241 is

= (25 × 432 )/241

= 44.81 years.

The decay constant k can be calculated as follows:

k = 0.693 /half life time

  = 0.693 /44.81 yrs

 = 0.015.

Now the time taken for the decay process is calculated by the following  equation:

t = 1/k log (25/6.25)

 = 1/0.015yr-1  log (25/6.25)

 = 39 years

Hence, 5 g of americium -241 will take 39 years to decay into its 6.25 g sample.

A box has dimensions of 2.0 cm time 4.0 cm times 8.0 cm, what is the volume of the box in milliliters?

Answers

Answer:

64 mL.

Explanation:

From the question given above, the dimension of box is:

Dimension = 2 cm × 4 cm × 8 cm

Thus, the volume of the box is:

Volume = 2 cm × 4 cm × 8 cm

Volume = 64 cm³

Finally, we shall convert 64 cm³ to mL. This can be obtained as follow:

Recall:

1 cm³ = 1 mL

Therefore,

64 cm³ = 64 cm³ × 1 mL / 1 cm³

64 cm³ = 64 mL

Therefore, the volume of the box in millilitres (mL) is 64 mL.

Water has low surface tension, which prevents capillary action from occurring.

Answers

Answer:

B water exhibits weak adhesion and cohesion which allows capillary action to occur.

Explanation:

took the test

Water exhibits strong adhesion and cohesion, which allows capillary action to occur.

What property of water allows it to move through a plant?

The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be 'pulled' up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.

What are adhesion and cohesion?

Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself and adhesion means that water likes to stick to other things.

If a block has the mass of 15.00 grams and measurements of 5.00cm by 3.00cm by 2.00cm what is the volume of the block?

Answers

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

Volume = 30cm³

The table shows four samples of carbon dioxide and the temperature of the water that they were dissolved in. Which of the samples most likely had the lowest solubility? I know the answer is sample one (78) but i can't find the right words to explain my answer.

Answers

Answer:

Sample 1 = 78°

Explanation:

As per the question, while testing the solubility of a solution comprising of water and carbon dioxide, sample 1 is likely to have the lowest solubility with the temperature of the water being 78°, the maximum. The reason for this result is that the 'solubility of carbon dioxide in the water' falls with an increase in the temperature due to the increase in kinetic energy which will enhance the motion between the molecules and allow them to escape.' Thus, the water with maximum temperature will have the lowest solubility. Hence, sample 1 is the correct answer.
