You are watching: Which of the following contains the smallest amount of matter
honeybees space covered with tiny hairs. What function do you think the hairs execute as the bee travels native flower to flower
It helps choose up the pollen, therefore that means they deserve to carry an ext and transfer it from flower come flower.Idk the it’ll do, however hope the helps!
1. Mass of 1 mole of raindrop: 301.10 x 10²⁰ kg
2. The number of moles the raindrops through the mass equal the the fixed of Pacific ocean: 0.02351 mol
A mole includes 6.02214076×10²³ or around 6.022 x 10²³ particles, the variety of 6.02214076×10²³ is called Avogadro"s number.
1. A mole that raindrop has 6.022×10²³ raindrops, therefore the fixed of 1 mole the raindrops is
M = 50 mg x 6.022 x 10²³ = 301.1 x 10²³ mg = 301.10 x 10²⁰ kg
2. The mass of the Pacific ocean is 7.08 x 10²⁰ kg, for this reason the moles of raindrop v the same mass is 0.02351 mol

Draw the lewis framework of the hypochlorite ion clo- . Include lone pairs
Solution:- Hypochlorite ion
total valence electrons = 7 + 6 +1 = 14
(note:- if there is negative charge climate it is added and if there is positive charge climate it is subtracted while calculating the valence electrons)
Both Cl and also O atoms wants to complete their octet and so for this we placed a solitary bond between them. Solitary bond method two electrons, so the continuing to be electrons would certainly be 14 - 2 = 12
It method 12 electrons will certainly be put as lone pair of electrons. To complete the octet, we placed 6 dots approximately each that the atom. Oxygen is an ext electron an adverse than Cl, therefore we show the -1 fee for oxygen.
