It will get lower since the pressure around the barometer gets lower
Well im in middle school and to me that looks like a skin cell breking into two cells so how i would draw that is why it would do that (cause) or how it does it. Hope it works
Answer:
1) CO₂
2) 0.2551 g
Explanation:
The balanced reactions are:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂
1) The gas produced is CO₂.
2) Calculate mass of CaCO₃:
(0.5236 g) (0.4230) = 0.2215 g CaCO₃
Convert to moles:
(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃
Find moles of CaCO₃:
(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂
Convert to mass:
(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂
Calculate mass of MgCO₃:
(0.5236 g) (0.5770) = 0.3021 g MgCO₃
Convert to moles:
(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃
Find moles of MgCO₃:
(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂
Convert to mass:
(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂
Total mass of CO₂:
0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
Answer:
Carbon dioxide is the waste released
Answer:
Five days prior to ovulation and day of ovulation represents a six day fertile window of a women’s cycle
Explanation:
In the five days prior to ovulation and day of ovulation, the chances of conception are high. These six days represents the fertile window of a women’s cycle during which the sperm with a life span of five days and egg with a life span of 24 hours can fuse. However, likelihood of conceiving increases if two individuals mate in the first three days of these six days fertile window of women’s cycle.
