6) Alveoli receive oxygen pass to blood

9) Oxygen passes into the blood

11) Alveoli receives carbon dioxide from the blood

12) Oxygen-rcih blood flows to the heart

3) Carbon Dioxide moves from bonchioles to bronchi

What molarity is prepared when a solution contains 0.277 moles of calcium bromide in 500 mL of solution (must change mL to Liter
Vladimir79 [104]

Answer:

0.554M of Calcium Bromide

Explanation:

Molarity by defintion is #of moles of something/litres of solution.

Therefore, here, we have 0.277 moles of calcium bromide and 500mL (divide 500ml by 1000 to go from mL to L because for every 1L there's 1000mL) or 0.5L.

Molarity= 0.277/0.5 = 0.554M of Calcium Bromide

Someone please help! I just started chem and what’s an easy way to tell apart chemical and physical changes? For some reason I k
MrRissso [65]

Chemical change is when the nature of something changes. Physical change is when a physical component changes.

Chemical change:

  • not easily reversible
  • new product formed
  • reactants are used (two products form a new one e.g iron and oxygen forms rust)
  • heat is released/absorbed

Example: Wood burns, it releases heat, produces CO2 and ash and you cannot reverse the burning.

Physical Change:

  • easily reversible
  • no new products formed
  • is often a state change

Example: Ice melts, water is formed, water can freeze again.
