Hey there!:
absorbance = log 100 - log Transmitance
absorbace = 0.85
log 100 = 2
- log transmitance = absorbace / log 100
0.85 / 2= 0.425
transmitance = 10 ^ ( - 0.425 )
transmitance = 0.376
Answer:
A simple example of decomposition reaction is hydrolysis of water where a water molecule is broken down into hydrogen and oxygen gas.
Answer:
6.25% of the original amount
Explanation:
half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.
after 1 month= 50%
after 2 months= 25%
after 3 months= 12.5%
after 4 months= 6.25%
T=2T
m=10 g
m=m₀2^(-t/T)
m₀=m/{2^(-2T/T)=m/2⁻²
m₀=10/2⁻²=40 g
40 grams
<u>Answer:</u> The correct answer is
is the base and
is the salt.
<u>Explanation:</u>
Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce salt and water as products.
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and a base is defined as a substance which accepts protons.
For the given chemical reaction:
![NH_3+HCl\rightarrow NH_4Cl](https://tex.z-dn.net/?f=NH_3%2BHCl%5Crightarrow%20NH_4Cl)
Here,
is a base because it is accepting proton and HCl is an acid because it is loosing proton.
is considered as a salt because it is formed by the combination of acid and base.
Hence, the correct answer is
is the base and
is the salt.
