different fuels emit different amounts of carbon dioxide in relation to the energy they produce when burned to analyze
I'm pretty sure what you are trying to ask for is radiative energy, light energy, and electronic energy.
Radiative since the microwave is releasing radiation,
Light since there is light inside the microwave,
Electronic since it is plugged in and uses electricity.
You can also use sound, but I don't think every microwave makes sound.
Answer:
Explanation:
a )
pH = - log[ H⁺]
8.26 = - log[ H⁺]
[ H⁺] = 10⁻⁸°²⁶ mole / l
= 5.49 x 10⁻⁹ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 5.49 x 10⁻⁹
= .182 x 10⁻⁵ moles / l
b )
10.25 = - log[ H⁺]
[ H⁺] = 10⁻¹⁰°²⁵ mole / l
= 5.62 x 10⁻¹¹ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 5.62 x 10⁻¹¹
= .178 x 10⁻³ moles / l
c )
4.65 = - log[ H⁺]
[ H⁺] = 10⁻⁴°⁶⁵ mole / l
= 2.24 x 10⁻⁵ moles / l
[ H⁺] [OH⁻] = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / 2.24 x 10⁻⁵
= .4464 x 10⁻⁹ moles / l
Answer:
118 neutrons
Explanation:
There are three subatomic particles in an atom namely: electron, neutron and proton. The mass number of an atom is calculated by adding the proton no. (atomic mass) + neutron no.
That is;
Mass no. = proton no. + neutron no.
This means that to obtain the neutron no. in the atom of an element, we subtract the no of protons or atomic mass from the mass number.
According to this question, Plutonium-196 is said to have an atomic number of 78. The mass no. is 196, hence, the number of neutrons is:
196 - 78
= 118 neutrons.
