31.2 ml of 0.200 M NaOH
18.2 ml of HF
Required
The molar concentration of HF
Solution
Titration formula
M₁V₁n₁=M₂V₂n₂
n=acid/base valence (amount of H⁺/OH⁻, for NaOH and HF n =1)
Titrant = NaOH(1)
Titrate = HF(2)
Input the value :

Steroids are like hormones that
greatly influences bodily activities mostly in growth and function. These
functions may modify, change and control one’s body organs or system that’ll
vary in form, shape or structure due to these hormone-like compounds and also,
it can affect one’s psychological and neurological state. There are several
types of steroids. Examples can include:
<span><span>
1. </span>Sex steroids. These are can influence reproduction and
sex characteristics.</span>
<span><span>
2. </span>Anabolic steroids. Most abused in many athletic
activities. These steroids are used for muscle and bone growth. </span>
Answer:
1.239 * 10^8 Kg
Explanation:
Since all the electricity consumed comes from natural gas;
amount of electricity consumed = 700 * 300,000 = 2.1 * 10^8 kWh
So, amount of CO2 consumed is given by;
amount of electricity consumed * amount of CO2 per kWh
Hence,
Amount of CO2 = 2.1 * 10^8 kWh * 0.59 = 1.239 * 10^8 Kg
To find the molarity of the compound, simply determine the molar mass of MgCl2 and then convert 50 g to moles using the molar mass of the compound. Then convert 150 ml to L = 0.15 L
Then divide the moles amount by the volume in L.
A) If volume increases, temperature increases
The law is V/T, meaning the two values are directly proportional, as one increases, the other increases too.
