3. Atomic theory, which describes the atoms that make up matter, has been 1 point explored for centuries. Scientists in ancient Greece first proposed that
matter was made of units called atoms. For many years, scientists thought
atoms were solid and could not be divided. Then, in the nineteenth century,
scientists began to discover the particles that make up atoms. Modern
techniques have allowed scientists to split atoms into increasingly smaller
particles. Which of the following statements about theories is supported
by the history of the atomic theory?*
a. If new evidence contradicts earlier theories, it is a result of an experimental error.
b. Experiments with modern equipment cannot be used to support earlier theories.
c. A theory is discarded when new evidence contradicts a part of the theory.
O d. Theories can change in response to new evidence.

What is the relation between concentration of reactants and the rate of chemical reaction?

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
