Answer:
A lower ph is always more acidic, due to the increased concentration of hydrogen ions in the solution/substance.
A ph of 3 is 100 times more acidic than a pH of 5, and this is due to the increments on the scale.
<span>Calcitriol </span>is the active form of vitamin D. (D)
The value of Triangle G is A) Less than 0.
Answer:
0.075 moles of iron oxide would be produced by complete reaction of 0.15 moles of iron.
Explanation:
The balanced reaction is:
4 Fe + 3 O₂ → 2 Fe₂O₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- Fe: 4 moles
- O₂: 3 moles
- Fe₂O₃: 2 moles
You can apply the following rule of three: if by stoichiometry 4 moles of Fe produce 2 moles of Fe₂O₃, 0.15 moles of Fe produce how many moles of Fe₂O₃?

moles of Fe₂O₃= 0.075
<u><em>0.075 moles of iron oxide would be produced by complete reaction of 0.15 moles of iron.</em></u>
The distance light travels in 1 second - <span>186,282 miles
Therefore distance it takes to travel within 182 seconds - </span><span>186,282 miles/second x 182 seconds
Therefore to find the answer we need to </span>multiply the distance it travels within a second with the amount of seconds it takes
correct answer is A) <span>186,282 ⋅ 182</span>
