Answer:
B
Explanation:
Solar power takes in light and turns it into a usable energy. if used in a vehicle that would take light energy and transform it into mechanical energy.
Answer:
4804.5 g of SO₂ are needed to the reaction
Explanation:
The reaction to produce sulfuric acid is:
2SO₂ + O₂ + 2H₂O → 2H₂SO₄
Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.
If 1 mol of O₂ react to 2 moles of SO₂
Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂
We convert the moles to mass, to know the answer:
75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂
I think it is a and c but i’m not sure
Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by
Amount of mass remaining is given by
The amount of the substance that remains after 10400 years is .
C) A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons
Explanation:
The statement that best explains the behavior of chlorine is that its atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
- To form an ionic bond, two atoms combines together via electrostatic attraction between them.
- Ionic bonds are formed between metals and non-metals.
- The large electronegativity difference between the two specie is the driving factor.
- In forming NaCl compound, Na donates electron which is accepted by Chlorine.
- This leaves a positive charge on Na and a negative charge on chlorine and the ensuing electrostatic attraction forms an ionic bond.
To form the covalent bond, the chlorine shares their valence electrons between themselves. They have an equal affinity for these electrons and this leads to the formation of a non-polar covalent bond
