Answer:
MSDS -- Material Safety Data sheet
Explanation:
The full form of MSDS is Material Safety Data sheet. A Material Safety Data Sheet is a document which contains the information related to the potential hazards (fire or reactivity and environmental and health ) and includes how to work or use the chemical product safely.
It is regarded as an essential starting point for development of the complete health as well as safety program. MSDS also contains other information such as the use of the chemical, its storage and also handling and the emergency procedures that are related to the hazards of the material.
Answer:
The balanced chemical reaction is expressed as:
HCl + NaOH ---> NaCl + H2O
We are given the amount and the concentration of the sodium hydroxide reactant. This will be the starting point for the calculations.
0.100 mol NaOH/L solution (0.06 L solution) ( 1 mol HCl / 1 mol NaOH) = 0.006 mol HCl
Molarity = amount in moles / Volume of solution = 0.006 mol HCl/ 0.150 L
Molarity = 0.04 M
Explanation:
Answer:
this reaction is a double displacement reaction in which, Aluminium nitrate reacts with hydrogen sulphide to form nitric acid and Aluminium sulphide.
here is the balanced chemical equation for the above reaction :
2 Al (NO3)3 + 3 H2S -> 6 HNO3 + Al2S3
Answer:
Out of personal experience (lol), I'd say the stick of butter is hard, cold, and very smooth at first. Once heated up or just kept at room temp for a while, it becomes mushy.
Hope I helped! ☺
