CH2O2 formic acid I believe so
Answer:
Dissociation
Explanation:
When HCl and NaOH are mixed with water, the HCl and NaOH molecules interacts with the water, forming what is known as ions. Ions are atoms with electric charge.
When HCl, it forms H+ and Cl-. The mixture is acid because what define a mixture as acid is the amount of H+ ions.
When NaOH mixes with water, it forms Na+ and OH- ions. The amount of OH- ions in a mixture defines it as basic.
Answer:
Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container.
A common application of this is a hydraulic lift used to raise a car off the ground so it can be repaired at a garage. A small force applied to a small-area piston is transformed to a large force at a large-area piston. If a car sits on top of the large piston, it can be lifted by applying a relatively small force to the smaller piston, the ratio of the forces being equal to the ratio of the areas of the pistons.
Explanation:
Answer:
I guess second option i.e. More potential employment opportunities and revenue because collecting recyclable material needs manpower to collect them, and secondary employment in transport i.e. to collect all the material at one place we need transport and so on!
Answer:
0.00663 grams/liter
Explanation:
HCl is a mineral acid with a molar mass of 36.46 g/mol.
No. of moles= mass/RMM
Making mass the subject of the formula:
Mass=Number of moles × RMM
Therefore 0.00040 mol HCl has a mass of:
0.00040 mol × 36.46 g/ mol
=0.01458 grams.
0.01458 grams are in 2.2 liters, Therefore 1 liter will have
0.01458 grams/2.2 liters= 0.00663 grams
concentration= 0.00663 grams/liter
