Answer :
(a) 0.0152
(b) 0.0000000778
(c) 0.000001
(d) 1600.1
Explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example :
5000 is written as
889.9 is written as
In this examples, 5000 and 889.9 are written in the standard notation and and are written in the scientific notation.
(a)
The standard notation is, 0.0152
(b)
The standard notation is, 0.0000000778
(c)
The standard notation is, 0.000001
(d)
The standard notation is, 1600.1
Answer:
.055 mol/L
Explanation:
Henry's Law is about solubility of a gas in a liquid which is dependent on the partial pressure of gas above the liquid . According to it
C = k P where C is concentration of gas in the liquid , k is henry's constant and P is partial pressure of the gas .
Given k = .159 mol/L.atm
P = 265 mm of Hg
= 265 / 760
= .34868 atm
C = kP
= .159 x .34868
= .055 mol/L

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
