Answer:
MgCl2-> Mg+Cl
mass 5.00g Mass=1.263g
RFM Mg=24+35.5 ×2= 95 RFM= 24
moles= 5.00÷ 95= 0.0526 Moles=0.0526
Explanation:
mas of Mg= 1.263 grams
Answer:
Explanation:
Noise pollution occurs when we have a house which is more than 65 decibels. The effects of noise pollution include physical effects which can be respiratory agitation, headaches, high blood pressure, etc.
Another effect is the psychological effect such as depression, anxiety, fatigue etc. Stress can also lead to sleep disorders and lack of concentration.
The ways to reduce noise pollution are:
1. Using awareness campaign: People should be told about the harmful effects of noise. This will be vital in reducing noise.
2. Government control: Government can play their role by telling those who doesn't adhere to laid out rules regarding noise to pay a fine. Anyone found wanting should pay a fine.
Sulfur forms compounds in oxidation states −2 (sulfide, S2−), +4 (sulfite, SO32−), and +6 (sulfate, SO42−). I don't know what type of ion but hope this helps!! :)
Answer: The equivalent mass of the acid is 83.16 grams
Explanation:
To calculate the number of moles for given molarity, we use the equation:
Molarity of
solution = 0.1165 M
Volume of
solution = 24.68 mL = 0.02468 L
Putting values in equation 1, we get:
( as acidity of NaOH is 1)
For end point: gram equivalents of acid = gram equivalents of base = 
Mass of acid=


Thus equivalent mass of the acid is 83.16 grams
