Answer: The molarity of is 0.07 M
Explanation:
According to the neutralization law,
where,
= basicity = 1
= molarity of solution = ?
= volume of solution = 25.0 ml
= acidity of = 1
= molarity of solution = 0.1000 M
= volume of solution = 17.5 ml
Putting in the values we get:
Therefore, molarity of is 0.07 M
Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
Therefore, this means that the energy of the wave increases by a factor:
Therefore, the energy of the wave increases by a factor 1.21.
Lead has a different chemistry than most biological metals, but it can mimic some of them, such as calcium, iron, and zinc, because it tends to form 2+ ion like other metals, and these can be formed inside the body. Due to it different chemistry, lead prevents normal functioning of the enzymes it binds to, inhibiting them and poisoning the body.
Gold rarely forms ions, unless under extreme conditions that are not present in the human body. Gold ions, when ingested, are actually very toxic, so gold poisoning is possible. But because gold are so rare, gold poisoning is also a rare phenomenon.
The current divides according to the resistance; more current in the lower resistance, less in the higher resistance. This is called “parallel branches” or paths. The voltage is the same for both (all) branches.
The new temperature of the gas is 115 °C
From the question given above, the following data were obtained:
- Initial temperature (T₁) = 25 °C = 25 + 273 = 298 K
- Initial pressure (P₁) = 0.96 atm
- New pressure (P₂) = 1.25 atm
- New temperature (T₂) =?
The new temperature of gas can be obtained as follow:
Therefore, the new temperature is 115 °C
