Answer:
Explanation:
525ml of 0.6550M MgCl₂ => 0.525L x 0.650M = 0.3413mole MgCl₂
0.3413mole MgCl₂ = 0.3413mole x 94 g/mole = 32.1g MgCl₂
The reaction of the decomposition of water into oxygen gas and hydrogen is balanced as such:
Using conversion factors, 2.0 mol H2O is equivalent to 1 mol O2, as per the reaction.
1 mol O2 is equivalent to 32g O2 (1 mol O2 * 
)
Answer: 32 g of oxygen.
Answer:
Electrical conductivity
Explanation:
note the words electrical and conductivity.
Electrical + conductivity = the ability of an object to carry electricity
Hope this helps!
Answer:
The correct answer is - C) a different number of neutrons per atom.
Explanation:
Isotopes of an element are the same element and same atomic number but with different atomic mass and physical properties. The difference in their atomic mass occurs due to isotopes of an element have a different number of neutrons per atom.
The number of protons and the numbers of electrons are the same in the isotopes but only change occurs in the numbers of the neutrons. In isotopes of uranium U-233, U-235, and U-238 have the same number of protons but a different number of neutrons per atom.
