Answer:
The volume is 22,710 980(38) litres for the ideal gas
This is a synthesis reaction or a combination reaction
NaCl + H2O = HCl + NaOH
FIRST write the equation and balance the equation THEN convert the volume of the gas to moles of the gas PV=nRT THEN according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt FINALLY calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)
10 gm salt in 100 ml water- let its concentration be x
We want 2x(A. T. Q)
For decreasing concentration, we need higher solvent(water here)
x= 100ml
2x=2(100)ml
We already had 100 ml
So 200-100=100
100ml is correct
Answer:
In the lab, students were encouraged to look at different types of rocks and minerals. They were also told to observe the physical properties of the rocks and minerals. Based on these physical properties, the children were able to distinguish the different types of rocks and minerals. The major differences which the children will focus on will be the color, shape, hardness, luster, streak, fracture and cleavage of the rocks and minerals.
