Answer:

700 mL of ethanol would be added

Explanation:

Given data:

Volume of ethanol added to make 40% v/v solution = ?

Total volume of solution = 1750 mL

Solution:

We will calculate the 40% 1750 mL which will be the volume of ethanol added to the water to make 40%v/v solution.

(40/100)× 1750 mL

0.4 × 1750 mL

700 mL

700 mL of ethanol would be added.

Answer: 1750 x 40 / 100 = 700ml

but since ethanol dissolves in water, it's not simply added to 1050ml of water as that would be less than 1750ml total.

a) yes Pb is more reactive  that Ag, Pb before Ag
b) no, Cu after H
c) yes, Cl2 is more active than I2
4) yes, Mg is more active

13.7 (as I think)
Al ³⁺  more active than Zn²⁺, Mn can react with  Zn²⁺, but not with Al ³⁺ , because Mn after Al but before Zn

If the two atoms participating in a bond have an electron negativity difference of 1.9 , what type of of bond would they be part
brilliants [131]

Answer:

Polar covalent bond.

Explanation:

When the bond is formed between the atoms by sharing the electrons the bond thus have covalent character.   The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.  When the electronegativity difference is less than 0.4 the bond is non polar covalent.

When bonded atoms have greater electronegativity difference i.e 2 or greater than two the bond is ionic because electron is transfer from low electronegative atom to highest electronegative atom.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

In case of H₂, Cl₂, Br₂ the bond has very high covalent character because of zero electronegativity difference.
