Answer:

The properties of a solid are that they form at a low temperature, particles have long range order meaning that the particles are fixed in place, the particles have a defined shape and volume, the solid particles are a low-energy state of matter, and solid particles are dense and incompressible. But on the other hand plasma particles form at high temperatures, plasma particles have short range order meaning that the plasma particles have little interaction, plasma particles fill all available space meaning plasma particles have no fixed shape or volume, plasma particles are the highest energy-state of matter, plasma particles are highly compressible, and plasma particles conduct electricity extremely well.

Calculate the volume of 1M NaOH required to neutralize 200 cc of 2M HCI. What mass of sodium

Nezavi [6.7K]

NaOH+HCl-> NaCl+H2O

1 mole of NaOH

1 mole of HCl.

To calculate volume of NaOH

CaVa/CbVb= Na/Nb

Where Ca=2M

Cb=1M

Va=200cm³

Vb=xcm³

Substitute into the equation.

2×200/1×Vb=1/1

400/Vb=1/1

Cross multiply

Vb×1=400×1

Vb=400cm³

To calculate the mass of sodium chloride, NaCl from the neutralization rxn.

Mole of NaCl=1

Molar mass of NaCl= 23+35.5=58.5

Mass=xgrammes.

Mass of NaCl=Number of moles × Molar mass.

Substitute

Mass of NaCl= 1×58.5

=58.5g

This is what I could come up with.

28 Which compound yields H + ions as the only positive ions in an aqueous solution?

MrMuchimi

Answer: (4) $CH_3COOH$

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water.
