Answer:
Crystalline and amorphous
Explanation:
Amorphous cells offer higher efficiency than the other two. ... Amorphous cells can withstand higher temperatures without output being affected, compared to poly or mono crystalline cells. Amorphous cells perform better in low light conditions compared to even the most efficient monocrystalline panels
Independent Variables are changes that occur in an experiment that are directly caused by the experimenter (you.)
Dependent Variables are changes that occur due to independent variables.
Controlled Variable is anything else that could influence the dependent variables.
Answer:
In this reaction HCl is the limiting reactant and aluminium is the reactant in excess.
Explanation:
Step 1: Data given
Mass of HCl = 69.0 grams
Mass of Al = 78.0 grams
Molar mass HCl = 36.46 g/mol
Atomic mass Al = 26.99 g/mol
Step 2: The balanced equation
6HCl(aq) + 2Al(s) → 3H2(g) + 2AlCl3(s)
Step 3: calculate moles HCl
Moles HCl = mass HCl / molar mass HCl
Moles HCl = 69.0 grams / 36.46 g/mol
Moles HCl = 1.89 moles
Step 4: Calculate moles Al
Moles Al = 78.0 grams / 26.99 g/mol
Moles Al = 2.89 moles
Step 5: Calculate the limiting reactant
For 6 moles HCl we need 2 moles Al to produce 3 moles H2 and 2 moles AlCl3
HCl is the limiting reactant. It will completely be consumed (1.89 moles). Aluminium is the reactant in excess. There will react 1.89 / 3 = 0.63 moles
There will remain 2.89 - 0.63 = 2.26 moles aluminium
In this reaction HCl is the limiting reactant and aluminium is the reactant in excess.
Since benzene is a covalently bonded chemical, ions and ionic bonds have no bearing on it. Simply put, boiling will cause the molecules to split from one another and turn into a gas.
Benzene boils at a greater temperature than other hydrocarbons with comparable molecular sizes, at 80°C (pentane and hexane, for example). The increased boiling point is most likely caused by how simple it is to create transient dipoles involving the delocalized electrons. At 111°C, methylbenzene begins to boil. Pure benzene and pure toluene have normal boiling points of 80.1 C and 110.6 C, respectively. Due to fewer intermolecular interactions, benzene has a lower boiling point than toluene.

Answer:
w = 0.00098 N
Explanation:
Given data:
Acceleration = 9.80 m/s²
Mass of honey = 0.0001 Kg
weight = ?
Solution:
Formula:
w = mg
w = weight
m = mass
g = acceleration due to gravity
Now we will put the values in formula:
w = 0.0001 Kg × 9.80 m/s²
w = 0.00098 N
