The statement that is NOT a part
of John Dalton's atomic theory Electrons move in specific orbits around the
nucleus of an atom. The statements ‘All elements are composed of atoms that
cannot be divided’, ‘All atoms of the same element are exactly alike and have
the same mass’ and ‘Every compound is composed of atoms of different elements,
combined in a specific ratio’ are not his theory.
Answer:
Explanation:(differences)SOLIDS have maximum intermolecular attraction and fixed shape so their particles are stable. LIQUIDS have small particles and are tightly held by molecular bond but not as tight as solid. liquid assume the shape of their container.GAS has free movement of particles...SIMILARITIES.. Liquid,solid and gases can be kept in containers...
Answer:
Positive acceleration involves speeding up, while negative acceleration involves slowing down.
Explanation:
I am so sorry if I was wrong!
Answer:
9.35g
Explanation:
The molarity equation establishes that:
So, we have information about molarity (2M) and volume (80 ml=0.08 l), with that, we can find the moles of solute:
The mathematical equation that establishes the relationship between molar weight, mass and moles is:
We have MW (58.44g/mole) and n (0.16 mol), and we need to find m (grams of salt needed) to solve the problem:
Baking soda and vinegar react because of an acid-base reaction. The product of this creates carbon dioxide.
