Answer:
<h2>1.686 × 10²⁴ atoms</h2>
Explanation:
The number of silicon atoms can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2.8 × 6.02 × 10²³
We have the final answer as
<h3>1.686 × 10²⁴ silicon atoms</h3>
Hope this helps you
Answer:
In general, the energy needed to remove an electron (the ionization energy) increases as the atomic number increases across a period.
Explanation:
Each additional proton increases the attraction between the nucleus and the electron.
Thus, it takes more energy to remove an electron as you add extra protons.
Answer:
Explained below:
Explanation:
The global temperature means the fluctuations in the temperature of the atmosphere and the oceans (existing in the earth surface).
Is the Earth’s global temperature is maintained or not depends on how much sunlight hits Earth versus and how much is returned, it also depends on the atmospheric level of carbon dioxide which prevents the earth from extreme cooling during the night.
Answer:
The answer to your question is: c) ATP
Explanation:
a) Carbon dioxide this molecule is a product of cell respiration so is very important for the cells but it isn't a form of energy cash, then this option is wrong.
b)Glucose: this molecule is used in the cell respiration process, from it the cell obtain ATP, but it isn't the energy cash for the cell.
c) ATP: this molecule is used by the cell to obtain energy, when an enzyme cuts off the phosphate bonds of this molecule it gets energy so this is the right answer.
d) Oxygen: oxygen is very important in the cell respiration process but It isn't usedas a energy cash.
I think that's the one with like snow hail and sleet
