His Dalton's Atomic Theory ideas form the atomic theory of matter. Here are his ideas. • All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. • All atoms of the same elements are alike. (One Atoms of element X Atoms of ement Y Compound of elemeite XandY atom of oxygenis like another atom of oxygen.) • Atoms of different elements are different. (An atom of oxygen is different from an atom of hydrogen.) • Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios. For example, water is a compound made up of 2 atoms of 1. What is the name of John Dalton's theory? 2. What are elements made of? 3. An atom of hydrogen and an atom of carbon are 4. What are compounds made of? 5. The ratio of atoms in HCI is: Atomic Structure J. J. Thomson was an English…

Fill in boxes and show correct answer please

A dead body was found within a closed room of a house where the temperature was a constant 70° F. At the time of discovery the core temperature of the body was determined to be 90° F. One hour later a second measurement showed that the core temperature of the body was 85° F. Assume that the time of death corresponds to  t = 0  and that the core temperature at that time was 98.6° F. Determine how many hours elapsed before the body was found. [Hint: Let  t1 > 0  denote the time that the body was discovered.] (Round your answer to one decimal place.)

Scenario: pouring liquid nitrogen (-196°C or – 320 °F) on a balloon . Link: https://www.youtube.com/watch?v=al5f9q845q0 List the variables (P, V, T, n) as either increasing, decreasing, or staying constant in this experiment. (2 of them will be constant) increasing decreasing staying constant Before Particle Picture After Particle Picture Time in video: 11 seconds Time in video: 30 seconds

Please don't provide handwritten solution .....

What is the frequency of light, in Hz, with a wavelength of 407.5 nm? Enter your answer using  scientific notation, "e". For example, if your answer is 5.2 x 10^2, enter "5.2e2'.

Plot your values of In(Ksp) VS. 1/Tand find the slope and y-intercept of the best fit line. Use the equation for the best fit line and the following equation In(K) = - AH° RT AS° R to calculate AH and AS for dissolving Borax What is the slope of your best fit line in the plot? What is AH (kJ/mol)? What is the y-intercept of your best fit line in the plot? What is AS (J/mol)?

measured to have a wavelength of (3.51x10^2) nm. What is the frequency • the correct number of significant figures • written in correct scientific notation Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: -9 8.55 MHz x10 of the light (in Hz)? c = 3.00 x 108 m/s 1 Hz = 1 s 1 Be careful with your units!!! For full credit, your answer must be:

Find the radius of a Pu nucleus. Pu is a manufactured nuclide that is used as a power source on some space probes. (answer in fm)

Heisenberg principal questions: The mass of sodium ions is 4.86 x 10-25 Kg. What will be error in velocity measurement if the error in position measurement is 1 nano-meter.(10-19 m)

A radioactive substance decays exponentially: The mass at time t is m(t) = m(0)ek", where m(0) is the initial mass and k is a negative constant. The mean life M of an atom in the substance is M = -k tekt dt. For a radioactive isotope, the value of k is -0.000149. Find the mean life (in years) of the isotope's atom. (Round your answer to one decimal place.) yr

Four research teams measured the rotation period of a newly detected neutron star, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 0.42 s for the period of the same star. Decide which of the earlier measurements was the most accurate, and which was the most precise. what was written most accurate most precise team in the notebook ? measurement measurement A "0.22s" B "0.4s + 0.1s" "0.52s + 10.%" D "between 0.30s and 0.34s"

Round your answer to 3 significant figures
