Answer

covalent reaction: If two atoms share electrons, in order to have a completely filled outer shell then the bond formed between the two atoms is called, covalent bond. Covalent bond is the strongest of all the chemical bonds.

Ionic reaction:I ionic reaction is the one in which the electrolytes are represented as dissociated ions. ionic bond formed when the atoms are held together by the attraction forces between the oppositely charged ions. EX. in sodium chloride, sodium atoms are held together by ionic bonds.

hope this helps! sorry for answering late, like reay late, Have a nice day tho! :)

Explanation:

1.54 ml

2. 54 g

3. -43.7 °C

4. 97 g

5. 17.74 kJ

Explanation:

1. Volume of water that only came from the melted ice is;

Volume of water plus melted ice-volume of warm water

151 ml - 97 ml = 54 ml

2.Mass of water that came from the melted ice.

Mass=density of water * volume of water from melted ice

M=1 g/ml * 54 ml = 54 g

3. The change in temperature of warm water will be;

Lowest temperature of ice-water mixture-Temperature of warm water

ΔT=0.9-44.6 = -43.7

4. Mass of warm water will be;

Mass of warm water= density of water*volume of warm water

M=1g/ml * 97 = 97 g =0.097 kg

5.

Energy released by warm water as it cools

Q=mcΔT

Given , mass of warm water=m=97

c=4.184 j/g*°C = 4184 J/(kg.C)

Δ= - 43.7

Q=0.097*4184*43.7 =17735.56 J

17735.56/1000 =17.74 kJ
