<span>When a chemist mixes oxygen gas and hydrogen gas to form
water, which is composed of one oxygen and two hydrogen atoms per molecule. The hydrogen and oxygen atoms bounds together by making a bond called covalent bond.<span> In a covalent bond, two atoms are bound
together because they each want to "share" each other's electrons.</span></span>
Answer:
Explanation:
A) bubbles show hydrogen gas escaping
B) the water reacted with sodium to form an alkaline solution
This is given by Avogagro number: 1 mol = 6.02*10^23 particles
Then you can do whichever to these two relations, because they are equivalent:
- 1mol / 6.02*10^23 representative particles, and
- 6.02*10^23 representative particle /1 mol
Only the second option of the question includes one of the valid conversion factors. Then, the conversion factor of the second option is the right answer
A mole of CO2 = 2 moles of O2
8 CO moles x 2 =
16 moles
Answer:
a.the smallest building blocks of matter
Explanation:
because atoms are the smallest building blocks of matter.
