If you increase the frequency, the photon will have more energy and can therefore transfer more electrons to the other side. As such, you will have an increased current.
1.strong acid: 2
2.weak acid:6
3.strong base:13
4.weak base:8
5.neutral:7
The Options are as follow,
<span>a.
it has 13 protons c. it has 13 neutrons </span>
<span>b.
it has 13 electrons d. it
has 7 neutrons</span>
Answer:
Option-d is the correct answer.
Explanation:
As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,
<span> Atomic Mass = # of Protons + # of Neutrons --- (1)</span>
Since;
Atomic Mass = 13
And,
# of protons = 6 (as number of protons = atomic number)
Putting values in equation 1,
13 = 6 - # of Neutrons
Solving for Number of Neutrons,
# of Neutrons = 13 - 6
# of Neutrons = 7
The unknown mineral is gold because of the similar properties of gold to that unknown mineral.
<h3>What is unknown mineral?</h3>
The unknown mineral is Gold because it has similar properties to the gold. Gold has density of 19.3 grams per cubic centimeter which is same to this unknown mineral. The hardness and mass of the mineral are also similar to the Gold.
So we can conclude that the unknown mineral is gold because of the similar properties of gold to that unknown mineral.
