Explanation:
Answer:
Mass = 234 g
Explanation:
Given data:
Mass of NaCl produced = ?
Moles of chlorine = 2.0 mol
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
now we will compare the moles of NaCl with chlorine gas.
Cl₂ : NaCl
1 : 2
2.0 : 2/1×2.0 = 4.0 mol
Mass of NaCl;
Mass = number of moles × molar mass
Mass = 4.0 mol × 58.5 g/mol
Mass = 234 g
Answer:
protons, neutrons, electrons
Answer:
Oxidation is defined as the chemical process in which substance loses electron and hydrogen or gain oxygen while in the process of reduction, substance gains electron and hydrogen or loses oxygen.
So, from the given equation:
a. It is an oxidation reaction as Rb loses one elctron.
b. It is a reduction reaction as Te gains two electrons and become Te2-
c. It is a reduction reaction as H atom gains electrons.
d. It is an oxidation reaction as P loses 3 electrons.
In the first paragraph state how climate change is the earth warming. Tell them how the warmer atmosphere has lead to the melting of snow and ice in the arctic and sever droughts in other areas of the world.
In the second paragraph talk about how large rivers are becoming smaller in regards to water volume and that the amount of water discharged into the ocean has also decreased greatly.
In the final paragraph write about how weather phenomena impact global warming. State that El Niño has led to lower floods in some place whereas other areas have experienced an increase in floods. Finally tell the reader how the lower water volumes and discharge leads to a change in the global ocean circulation.
