The density of Jena’s smoothie is 0.667 g/mL.
Mass = 200 g
Volume = 300 mL
Density = mass/volume = 200 g/300 mL = 0.667 g/mL
Answer:
yes
Explanation:
Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell.
The outermost structure that surrounds and supports plant and fungal cells should be A. Cell wall.
Answer:
E
Explanation:
So this question tests your understanding of mole:mole ratios.
So looking at the equation we see for every 3 O2 there's 4 NH3, we can even word it like for every 4 mol of NH3 that reacts you need 3 moles of O2. This gives us the mole:mole (mole to mole) ratio of 3 mol O2/ 4 mol NH3.
Now since you have 3.5 moles of NH3 you can use the ratio from above to convert it to O2 by simply 3.5molNH3 * 3mol O2/4mol NH3 ------> 2.625mol O2
