<u>Answer:</u> The given electronic configuration is long hand notation.
<u>Explanation:</u>
Long-hand notation of representing electronic configuration is defined as the arrangement of total number of electrons that are present in an element.
Noble-gas notation of representing electronic configuration is defined as the arrangement of valence electrons in the element. The core electrons are represented as the previous noble gas of the element that is considered.
The given electronic configuration of potassium (K): 
The above configuration has all the electrons that are contained in the nucleus of an element. Thus, this configuration is a long-hand notation.
Because pure silicon is a perfect semiconductor.
For room temperature, it rarely conducts, you can search for the threshold temperature, the characteristic equation is fairly complicated.
Answer:
C) the energy transferred between objects t different temperatures
Answer:
10.56 g
Explanation:
C4H10(g) + 13/2O2 (g) -------> 4CO2(g) + 5H2O(l)
Number of moles of butane = 3.49g/ 58 g/mol = 0.06 moles
1 mole butane yields 4 moles of CO2
0.06 moles of butane = 0.06 × 4/1 = 0.24 moles of CO2
Number of moles of oxygen = 17.1g/32g/mol = 0.53 moles of oxygen
6.5 moles of oxygen yields 4 moles of CO2
0.53 moles of oxygen yields 0.53 × 4/6.5 =0.33 moles of CO2
Butane is the limiting reactant
Theoretical yield of CO2 = 0.24 moles × 44g/mol = 10.56 g
Answer:
The bombarding particle is a Proton
Explanation:
A Nuclear transmutation reaction occurs when radioactive element decay, usually converting them from one element/isotope into another element. Transmutation is the process which causes decay, generally, alpha or beta.
¹⁶₈O(P,alpha) ¹³₇N, can be written as
¹⁶₈O + x goes to ¹³₇N + ⁴₂He
Where x can be anything, balancing the equation in order to give us the correct amount of proton number and nucleus number
16 + x = 13 + 4
x = 17 – 16 = 1, Hence we can say that x = ¹₁P
<u>¹⁶₈O + ¹₁P goes to ¹³₇N + ⁴₂He</u>
Here we can clearly see the bombarding particle is ¹₁P (proton). The ejected particle being ⁴₂He which is also known as an alpha particle
