We combine the two equations, like we would any mathematical system of equations. After addition of the two equations, we get:
Mg + 2H⁺(aq) + 2e⁻ → Mg⁺²(aq) + H₂(g) + 2e⁻
Cancelling like terms from both sides
Mg + 2H⁺(aq) → Mg⁺²(aq) + H₂(g)
Answer:
[O₂(g)] = 0.0037M
Explanation:
2SO₂(g) + O₂(g) => 2SO₃(g)
Conc: [SO₂(g)] [O₂(g)] [SO₃(g)] and [SO₂(g)] = [SO₃(g)]
Kc = [SO₃(g)]²/[O₂(g)][SO₂(g)]² => Kc = 1/[O₂(g)] = 270 if [SO₂(g)] = [SO₃(g)]
∴ [O₂(g)] = (1/270)M = 0.0037M
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain. ... The animals and plants eventually die.
Answer: i. The reaction consumes 3 moles of iron(III) oxide.
ii. The reaction produces 3 moles of aluminum oxide and 6 moles of iron.
Explanation:
The balanced reaction is :
According to stoichiometry:
a) 2 moles of aluminium consume = 1 mole of
6 moles of aluminium consume = moles of
b) 2 moles of aluminium produce = 1 mole of
6 moles of aluminium consume = moles of
2 moles of aluminium produce = 2 moles of
6 moles of aluminium consume = moles of
Answer:
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
Because radiation kills rapidly dividing cells (which is why we use it to treat fast-growing cancer cells), radiation exposure most increases the risk of cancers of rapidly dividing cells — leading to leukemia, lymphoma, breast cancer, bladder cancer, colon cancer, liver cancer, lung cancer, esophageal cancer, ovarian
