Hydrogen .When acids touches all metal hydrogen gas is emitted .Strong acids is one that can produce a high concentration of hydrogen ions.Hope this helped!
The student’s suggestion who provides enough evidence to be able to determine the value of each resistor is student D.
<h3>What is current?</h3>
The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
For the given set of parallel resistors, we need to find the resistance of each resistor.
From the Ohm's law, V =IR
R = V/I
Resistance value depends upon the voltage difference across the resistor and the current flowing through that resistance.
Thus, the student D gives enough evidence to find resistance of the circuit is

The working equation to be used here is written below:
Q = kA(T₁ - T₂)/Δx
where
Q is the rate of heat transfer
k is the heat transfer coefficient
A is the cross-sectional area of the wall
T₁ - T₂ is the temperature difference between the sides of the wall
Δx is the thickness of the wall
The solution is as follows:
Q = (0.69 W/m²·°C)(5 m × 6 m)(50°C - 20°C)/(30 cm * 1 m/100 cm)
Q = 2,070 W/m
We know, Volume = Mass / Density
Here, mass = 4 Kg = 4000 g
d = 1,897 g/ml
Substitute their values,
v = 4000 / 1897
v = 2.108 ml
In short, Your Answer would be 2.108 mL
Hope this helps!
