You learned that darker colors absorb more light energy than lighter clor thus darks colot object become hotter when expose to sunlight to prove this you want to determine if the temperature of a dark colored soda drink will be higher than light soda drink you exposed glasses the sun for 30 min. and measure the temperature of the darkest color soda drink is higher than lighter clored soda drink you repeat the same experiment but this time in dark room you observe that the temperatures of liquid is the same What is experimental set up?
What is control?
Which is/are independent varibale?
What is dependent variable?
What factors you will keep constant?
plss help meee

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the increase of protons   hope this
