Answer:
I would say about 90 Celsius
Explanation:
Answer:
The answer is D, Magnesium.
Answer:
The correct answer is - false.
Explanation:
At the energy-generating station, when the coal is burned, the chemical energy store in the coal converted into thermal energy and light or luminous energy.
The thermic energy generated used to heat and boil the water or liquid to generate the gas and generate the kinetic energy to move the fan that is desgined to generate the electrical energy.
Thus, the statment is false statement as it does not convert into sound energy.
Answer:
7.92 mL
Explanation:
There is some info missing. I think this is the original question.
<em>A chemistry student weighs out 0.0617g of acetic acid (HCH₃CO₂) into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1300 M NaOH solution.
</em>
<em>
Calculate the volume of solution the student will need to add to reach the equivalence point. Round your answer to 3 significant digits.</em>
<em />
First, we will calculate the moles of acetic acid (MW 60.05 g/mol).
0.0617 g × (1 mol/60.05 g) = 1.03 × 10⁻³ mol
Let's consider the neutralization reaction between HCH₃CO₂ and NaOH.
HCH₃CO₂ + NaOH ⇄ NaCH₃CO₂ + H₂O
The molar ratio of HCH₃CO₂ to NaOH is 1:1. The moles of NaOH are 1.03 × 10⁻³ moles.
The volume of 0.1300 M NaOH that contains 1.03 × 10⁻³ mol is:
1.03 × 10⁻³ mol × 1000 mL/0.1300 mol = 7.92 mL
