1. List five exothermic reactions that are going on around you. (10 points)

Think about chemical reactions in which substances become colder, which

means that they are releasing heat. Be sure to include only chemical reactions,

Answer :

Exothermic reactions are those reactions in which a system releases its heat energy to surroundings whereas during endothermic reactions a system absorbs heat energy from surroundings.

Explanation :

Five exothermic reactions that are going on around us

a) Making of ice cubes

b) Rusting of iron

c) Nuclear fission reaction

d) Cellular respiration

e) Condensation of water vapor to form rain.

Following are some endothermic reactions;

1) Photosynthesis  

2) Mixing of water in Ammonium Nitrate

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
