It has 4 significant figures. If you see the Zero after the one decimal point you don’t count that and instead just started at 6
Answer:
Less than one gram
Explanation:
Since there is no whole number before the decimal it means that the number is less than whole meaning it is less than one gram
Answer:
large intestine is right below the stomach and gallbladder and has the small intestine in the middle
works mainly with the digestive system
The large intestine gets rid of the undigested food that the small intestine could not absorb and reabsorbs water from the digestion
other organs include:
pancreas
small intestine
gallbladder
liver
stomach
esophagus
salivary glands
the function of the large intestine is to get rid of waste, absorb water, and absorb any nutrients which did not get absorbed in the small intestine
Explanation:
Answer:
Beryllium-9 is the isotope of beryllium with relative atomic mass 9.
Answer:
T° freezing solution → -11.3°C
T° boiling solution → 103.1 °C
Explanation:
Assuming 100 % dissociation, we must find the i, Van't Hoff factor which means "the ions that are dissolved in solution"
This salt dissociates as this:
SnCl₄ (aq) → 1Sn⁴⁺ (aq) + 4Cl⁻ (aq) (so i =5)
The formula for the colligative property of freezing point depression and boiling point elevation are:
ΔT = Kf . m . i
where ΔT = T° freezing pure solvent - T° freezing solution
ΔT = Kb . m . i
where ΔT = T° boiling solution - T° boiling pure solvent
Freezing point depression:
0° - T° freezing solution = 1.86°C/m . 1.22 m . 5
T° freezing solution = - (1.86°C/m . 1.22 m . 5) → -11.3°C
Boiling point elevation:
T° boiling solution - 100°C = 0.512 °C/m . 1.22 m . 5
T° boiling solution = (0.512 °C/m . 1.22 m . 5) + 100°C → 103.1 °C
