Silicon (si) has two electrons in its outer p orbitals.
Explanation:
For the element of SILICON, you previously know that the atomic number shows the number of electrons. That indicates there are 14 electrons in a silicon atom. Looking at the design, you can see there are two particles in shell one, eight in shell two, and four in shell three. Si which is 4 elements from the left side of the table,first 2 electrons are s orbitals when next two electrons go to Si
<span>We know the relation between heat and temperature follows the formula:
Q = Ce * m * (Tf-Ti) , where Q is heat transfer, Ce is specific heat, m is mass, Tf is final temperature and Ti is initial temperature.
Note that heat value is given in kj so we need to change to joules, then as heat is absorbed the final temperature will increase.
4,689 = 0.385 * 34.2 * (Tf-24)
Tf = 4,689 / (0.385 * 34.2) + 24 =380.12ÂşC</span>
The answer is electrolyte.
That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.
Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .
Answer:
Volume = 10 cm3
Density = 2.3g/cm3
Explanation:
volume:
30ml - 20ml = 10ml = 10cm3
density:
density = mass/volume
23/10
2.3g/cm3
