A student creates a “volcano” by mixing vinegar and baking soda is a Experiment in the following way.
Explanation:
- The baking soda and vinegar volcano is a fun chemistry project that a student can do to simulate a real volcanic eruption or as an example of an acid-base reaction.
- The chemical reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) produces carbon dioxide gas, which forms bubbles in dishwashing detergent. The chemicals are non-toxic (though not tasty), making this project a good choice for scientists of all ages.
-
The cool red lava is the result of a chemical reaction between the baking soda and vinegar.
- In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.
- As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until—thanks to the detergent—the gas bubbles out of the mouth of the volcano.
Answer:
C is the answer!
Explanation:
temperature is a measurement of the average kinetic energy of the particles in an object
50g U ( 1mol/ 238.03g) = .2 moles
238.03 is the molar mass of uranium- can be found on periodic table
Answer:
K+ ion is identical to argon and the Br- ion is identical to krypton
Explanation:
Potassium atoms have 19 electrons, when they become an ion they lose an electron and now have 18 electrons. The noble gas that has 18 electrons is Argon. Bromine atoms have 35 electrons, when they become an ion they gain an electron and now have 36 electrons. The noble gas that has 36 electrons is Krypton.
