Use this formula which is th opposite of the formula used to find absorbance when you have the %T

(10^(-A))×100
where A=absorbance so

Answer:

14.12% the percent light transmitted through the colored sample at this collected wavelength.

Explanation:

Formula used to convert absorbance into transmittance is:

A=\log \frac{I_o}{I}=-\log[T]

T=\frac{I}{I_o}

where,

A = absorbance of solution

T = Transmittance

I_o = incident light

I = transmitted light

Given = A = 0.85

0.85=-\log[T]

T=0.1412

0.1412=\frac{I}{I_o}

I=0.1412\times I_o

Percentage of light transmitted to color solution:

\frac{I}{I_o}\times 100=\frac{0.1412\times I_o}{I_o}\times 100=14.12\%

14.12% the percent light transmitted through the colored sample at this collected wavelength.

What happens when a metal is reduced. Give an example of a metal being reduced
AlexFokin [52]

Answer:

The oxidation number of the metal decreases

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

The metal element iron, is reduced from Fe⁺³ in Fe₂O₃ to Fe⁺² in FeO

Explanation:

When an element gains electron, the element becomes reduced, hence when a metal is reduced, the metal gains electrons, which reduces the oxidation number of the metal

An example of a metal being reduced is;

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

In the above reaction, the iron (III) oxide is reduced to iron (II) oxide by aluminium metal.

The muscle layer of the heart is known as the
ladessa [460]

Answer:

Myocardium

Explanation:

myo means "of muscle" or "relating to muscle"

cardium denotes tissues or cells that are associated with the heart.

The myocardium is an involuntary (we don't have to actively contract it), smooth muscle. The cells that make up the muscle are called cardiomyocytes.

These cells/tissues are hugely important for the normal functioning of the heart, and disruption is associated with diseases such as ischemic heart disease.

Choose any metal atom from Group 1A, 2A, or 3A. What charge will it adopt when it ionizes?​
Ksenya-84 [330]

Answer:

Positive charge.

Explanation:

Hello!

In this case, since elements belonging to groups 1A, 2A and 3A are mostly metals, we infer they have the capacity to lose electrons and therefore they become positively charged.

Some examples may be:

Na^+\\\\H^+\\\\Ca^{2+}\\\\Al^{3+}\\\\Sr^{2+}

Best regards!
