to write 0,0045 in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by 1000=103 . Hence in scientific notation 0.0045=4.5×10−3 (note that as we have moved decimal three point to right we are multiplying by 10−3 this is an example
Exothermic gives off heat/energy and endothermic takes in heat/energy. Exothermic example: a candle flame
Endothermic example: baking bread
In Exothermic, you can expect the surrounding temp. to rise, and in Endothermic you can expect the surrounding temperature to fall.
Hope this helps
Answer:
Has a hydroxide concentration of 0.01M
Explanation:
When NaOH dissociates, it gives 1mol Na+ and 1mol OH- this multiplies the concentration value and we get 0.01×1= 0.01M
