Why does a metal lawn
chair get hot in the sun
when the grass sitting in the
same sunlight remains cool,
to the touch?
1. Heat travels easily
through plants but
not metals.
2. Heat travels easily
through both plants
and metals.
3. Heat travels easily
through metal objects
but not through
plants.

heat travels easier through plants so plants dont heat up as much

thus is because metal is much more dense than the grass

- 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

i don,t know so just answer mine
