I think it could be a or d
Answer:
Protons, neutrons, and electrons
Explanation:
Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Answer:
alkenes and alkynes are considered as unsaturated hydrocarbons because they are capable of reacting with hydrogen in the presence of a catalyst to form a saturated hydrocarbon (alkanes)
Explanation:
A saturated compound contains a chain of carbon atoms joined by single bonds, with hydrogen atoms attached to each carbon atom.
Propane for example, CH₃-CH₂-CH₃.
It is saturated because all the carbon atoms holds maximum number of hydrogen atoms.
Alkenes such as Propene (CH₂=CH-CH₃) and alkynes like Propyne,
(CH₃-C≡C-H) are unsaturated because the central carbon atoms contain less number of hydrogen atoms than they possibly could.
Answer:
Silicon (Si) would be the answer
Explanation:
Hi there,
I believe that your answer to this will be 234 g NaCL
this is because i made a reaction equation:
The reaction equation:
2Na + Cl₂ → 2NaCl
Molar ratio of Na to NaCl = 2 : 2 = 1
Moles of Na = 92/23
= 4
Moles of NaCl = 4
Mass NaCl = moles x Mr
= 234 grams
Hope this is correct :)
Have a great day
