Answer:
Explanation:
Given that,
Area of sheet of Aluminium foil is 1 m²
Mass of the sheet = 3.636 g
The density of Aluminium, 
We need to find the thickness of the sheet in millimeters.
The density of an object is given in terms of its mass and volume as follows :
V = volume, V = A×t, t = thickness of the sheet
So,
Since, 1 cm = 10 mm
So,
t = 0.00134 mm
or
Answer:
moves molecules
Explanation:
I did this one yesterday! Active transport moves low to high concentration and passive does the opposite so C and D are not an option. Active transport requires energy and Passive Transport does not so it has to be A.!
Answer:
51.859 grams
Explanation:
Given:
Mass of sugar in the crunch cereal per serving= 11.0 grams
Mass of cereal served per serving = 60.0 grams
Molar mass of the sugar (C₁₂H₂₂O₁₁) = ( 12 × 12 + 22 × 1 + 16 × 11 ) = 342 grams
Number of moles of sugar per serving = Mass / Molar mass
= 11.0 / 342
= 0.03216 moles
Now,
0.03216 moles sugar requires 60 grams cereal
for 0.0278 moles of sugar, cereal required = (60 / 0.03216) × 0.0278
or
for 0.0278 moles of sugar, cereal required = 51.859 grams
Lava means wash in spanish.
Not totally sure, but I think it’s A.
