Answer:

D. Visible Light

Explanation:

D is the right answer because visible light is perceived by humans as color and the rest aren't visible at all. For example, if you broke a bone and have to have an X-ray done, you can't see the x-rays. When you are heating something in the microwave, you can't see the waves. And when you are listening to the radio in the car, you also can't see the waves.

Question 1.
cricket20 [7]

Answer:

Explanation:

D. 2 Fe's, 3 O's

An atom is the smallest indivisible particle of a substance. Most notations of elements in actual sense depicts the combining atoms.

In Fe₂O₃, the subscript gives the idea of the number of combining atoms and their combining ratios. Here, weh have 2 atoms of Fe and 3 atoms of Oxygen.

Activated carbon filters use chemical means to seperate impurities from air:

Chemical reactions occurs when compounds are formed. Activated carbon filters are made up of activated carbons in which impurities have been removed and the pores of the carbon structure have become widened. This leaves the carbon with much surface area for chemical reaction to occur between impurities and the carbon in form of chemical adsorption. One important thing to note is that, in chemical change, it is difficult to resolve the reactants after the product is formed. In physical change, simple seperation techniques are used to seperate the reactants out.

How many atoms of fluorine are in 5.6x10^22 molecules of MgF2.
Serhud [2]

Answer:

1.12 x 10²³atoms of F

Explanation:

Number of MgF₂ atoms = 5.6 x 10²² molecules;

 The unknown here is the number of Fluorine atoms found in the compound.

In MgF₂,

     1 mole of MgF₂ contains 2 moles of F;

From the given number of molecules we can also say that, MgF₂ contains 5.6 x 10²²atoms;

           1 mole of MgF₂ contains 2 moles of F;

    5.6 x 10²²atoms of MgF₂ will contain 2 x   5.6 x 10²² = 1.12 x 10²³atoms of F

Which acid is almost completely ionized in a dilute solution at 298k?
Alex777 [14]
Considering choices; 
a. CH3COOH
b. H2S
c. H2PO4
d. HNO3
The answer would be HNO3; this is because it the strongest acid. Strong acids are acids that are fully ionized while weak acids are only partially ionized. At the same concentrations, strong acids have a higher concentration of hydrogen than weak acids. Examples of strong acids include; hydrocloric acid and nitric acid, while weak acids include; ethanoic acids.

How many liters of 
Kruka [31]
The balanced equation for the above reaction is as follows
C₆H₁₂O₆(s) + 6O₂(g) --> 6H₂O(g) + 6CO₂<span>(g)
the limiting reactant in the equation is glucose as the whole amount of glucose is used up in the reaction.  
the amount of </span>C₆H₁₂O₆ used up - 13.2 g
the number of moles reacted - 13.2 g/ 180 g/mol  = 0.073 mol
stoichiometry of glucose to CO₂ - 1:6
then number of CO₂ moles are - 0.073 mol x 6 = 0.44 mol
As mentioned this reaction takes place at standard temperature and pressure conditions, 
At STP 1 mol of any gas occupies 22.4 L
Therefore 0.44 mol of CO₂ occupies 22.4 L/mol  x 0.44 mol = 9.8 rounded off - 10.0 L
Answer is B) 10.0 L CO₂
