Answer:
Protons: 50, Neutrons: 75, Electrons: 50
Explanation:
The atomic number, which in this case is 50, determines the number of protons and electrons an atom has. Take the atomic number and subtract the number of protons to get the number of neutrons.
Aluminum chloride is an ionic salt with the formula AlCl3. The reason for the three chlorine atoms is because aluminum donates an electron to each chlorine atom.
Answer:
Directly proportional:
A proportion of two variable quantities. when the ratio of two quantities are constant.
inversely proportional:
when one value decreases at the same rate that the other increases.
Explanation:
I hope this does help you, have a great day. :)
Complete combustion of acetylene generated carbon dioxide and water. This can be represent by following reaction
2C2H2 + 5O2 → 4CO2 + 2H2O
(2 mole) (4 mole)
From the above balanced reaction, it can be seen that 2 mole of acetylene on complete combustion generates 4 moles of carbon dioxide
i.e. 2 mole of C2H2 ≡ 4 mole of CO2
∴ 1.3 mole of C2H2 ≡ (4 X 1.3)/2 = 2.6 mole of CO2
Now, 1 mole of CO2 = 44 g
∴ 2.6 mole of CO2 = (44 X 2.6) = 114.4 g
Thus, <span>114.4 grams of carbon dioxide are produced from the combustion of 1.3 moles of acetylene</span>
