Explanation:
The viscosity of the water is most likely to decrease. The surfactant will disrupt the intermolecular forces of the water molecule. They would actually decrease the molecular bond of water molecules and form a bond themselves with the water molecules(adhesion>cohesion). Thus the viscosity of water is decreased.
Answer:
12.7 mol
Explanation:
<em>A chemist measures the amount of fluorine gas produced during an experiment. He finds that 482. g of fluorine gas is produced. Calculate the number of moles of fluorine gas produced.</em>
Step 1: Given data
Mass of fluorine (m): 482. g
Step 2: Determine the molar mass (M) of fluorine
Fluorine is a diatomic molecule of chemical formula F₂. Its molar mass is:
mF₂ = 2 × mF = 2 × 19.00 g/mol = 38.00 g/mol
Step 3: Determine the number of moles (n) corresponding to 482. g of fluorine
We will use the following expression,.
n = m/M
n = 482. g/(38.00 g/mol)
n = 12.7 mol
B .combustion because HOH and CO2 are the products of complete combustion
Answer:
(A) A layer of gases that surrounds the planet
Explanation:
An atmosphere is the layer of gases that surrounds a planet. In the case of Earth, the atmosphere contains the air we breath, as well as other gases that protect us from the Sun's harmful rays.
