PLZ HELP, GIVING BRAINLIEST!!
Identify the following as an endothermic or exothermic with proper explanation.
If you place an ice cube on a watch glass for two minutes, is it endothermic or exothermic? support with evidence. Also, mention if there is any phase change in the reaction.

Explain which atom l or m is more stable and why

How are elements arranged in a periodic table

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
