The iron uses heat waves to flatten the shirt. You can also you water to help the process and create steam. The steam will help soften the shirt making it easier to flatten. I am not sure if this is correct but it should help to understand why the shirt gets hot.

Find a mole of 0.0960 g of H2SO4
nignag [31]
Molar mass H₂SO₄ = 98.079 g/mol

1 mol -------- 98.079 g
? mole ------ 0.0960 g

moles = 0.0960 * 1 / 98.079

= 0.0960 / 98.079

= 9.788 x 10⁻⁴ moles

hope this helps!

if the balance indicated that the evaporating dish has a mass of 44.8 g and you want to have exactly 5.0 g of copper. what shoul
AleksandrR [38]

49.8 g should be the balance read.

Explanation:

Adding the mass of the evaporation dish 44.8 g with the mass of the copper 5 g you obtain 49.8 g.

On the balance you put first the evaporation dish (or a watch glass) over which you add copper until you reach 49.8 g.

Identify which one of the three methods of analysis (i.e., TLC, IR and melting point) provides information about the structure o
Alex787 [66]

Answer:

IR provides structural information about a molecule. TLC and melting point analysis do not provide structural information.

Explanation:

IR gives information about the functional groups present in a molecule. The vibrational frequency of each functional group gives information about the structure of the entire molecule.

Structural features of a molecule are deduced by matching the vibrational frequencies of  groups obtained from the IR spectroscopy with that of known functional groups in literature.

Melting point is a qualitative method that can only yield information about the identity of a compound and not its structure. Each compound has its unique melting point recorded in literature and any pure sample of the same compound must have the same sharp meting point.

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. After separating the components of the mixture, it does not give any information regarding the identity or the structure  of the components of the mixture.

Therefore, only IR yields structural information about a sample.
