The answer is D. Rubber. Because A, B, and C are metal materials that will insulate heat without any gaps. Hope this helped!
Answer:
5.89 g × 10⁶ μg
Explanation:
Step 1: Convert 5.00 scruples to grains
We will use the conversion factor 1 scruple = 20 grains.
5.00 scruple × 20 grain/1 scruple = 100 grain
Step 2: Convert 100 grains to ounces
We will use the conversion factor 1 oz = 480 grains.
100 grain × 1 oz/480 grain = 0.208 oz
Step 3: Convert 0.208 oz to grams
We will use the conversion factor 1 oz = 28.34 g.
0.208 oz × 28.34 g/1 oz = 5.89 g
Step 4: Convert 5.89 g to micrograms
We will use the conversion factor 1 g = 10⁶ μg.
5.89 g × 10⁶ μg/1 g = 5.89 g × 10⁶ μg
δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
The lead (Pb) in the lead storage battery act as an anode
<h3>What is Voltaic Cell?</h3>
A voltaic cell or galvanic cell is an electrochemical cell that uses chemical reactions to produce electrical energy.
<h3>Parts of voltaic cell</h3>
Anode where oxidation occurs Cathode where reduction occurs.
Therefore, Pb acts as anode and PbO2 act as a cathode.
Given,
E° cell = 2.04v
Faraday constant= 96485 C/mol
Moles of electron transferred n= 2
∆G = -nFE°
= -2 × 96485 × 2.04
= 393.658kJ
Thus we concluded that the δg° for the reaction having e° cell = 2.04v. is 393.658kJ.

Answer:
It is a right triangle
Explanation:
We are given the directions in which a bird flew to make a triangle.
We are required to determine whether the triangle is right angle.
What is a right triangle?
- It is a triangle that has a right angle between the shorter sides or legs
- The triangle also obeys the Pythagoras theorem, such that the square of the two legs is equal to the square of the hypotenuse.
- Such that if the two legs are, a and b while c is the hypotenuse.
Then, a² + b² = c²
In this case;
Taking the legs as a= 21 yards and b = 72 yards and the hypotenuse, c = 75 yards.
Then we can determine whether it is a right triangle;
a² = 21² = 441
b²= 72² = 5184
c² = 75² = 5625
a² + b² = 5625
Therefore; a² + b² = c²
Hence, the triangle is right triangle.
