Answer:
Tenant farming is an agricultural production system in which landowners contribute their land and often a measure of operating capital and management, while tenant farmers contribute their labor along with at times varying amounts of capital and management.
Explanation:
Answer is in picture below.
Use 100 grams of the compound:
ω(Cl) = 85.5% ÷ 100%.
ω(Cl) = 0.855; mass percentage of the chlorine in the compound.
m(Cl) = 0.855 · 100 g.
m(Cl) = 85.5 g; mass of chlorine.
m(C) = 100 g - 85.5 g.
m(C) = 14.5 g; mass of carbon.
n(Cl) = m(Cl) ÷ M(Cl).
n(Cl) = 85.5 g ÷ 35.45 g/mol.
n(Cl) = 2.41 mol; amount of chlorine.
n(C) = 14.5 g ÷ 12 g/mol.
n(C) = 1.21 mol; amount of carbon.
n(Cl) : n(C) = 2.41 mol : 1.21 mol = 2 : 1.
This compound is dichlorocarbene CCl₂.
Answer: increases by
As a chlorine atom becomes a negative ion, the atom "increases by" an electron
Explanation:
Chlorine atom has an atomic number of 17, and an electronic configuration of 1s2, 2s2 2p6, 3s2 3p5 showing 7 valence electrons in its outermost shell.
Hence, it receives a single electron to achieve a stable octet structure with electronic configuration of
1s2, 2s2 2p6, 3s2 3p6. Therefore, Cl- is a univalent negative ion with 8 valence electrons in its outermost shell. The increase is shown below
Cl + e- --> Cl-
Thus, as a chlorine atom becomes a negative ion, the atom "increases by" an electron
60 days have passed. In every 12 days the radioisotope loses half of its life. So in the first 12 days, from 160 grams it decreases to half so it becomes 80 grams. The second 12 days, from 80 grams, it decreases to half and becomes 40 g. The third 12 days, from 40 it becomes half to 20 g. The fourth 12 days, from 20 g it becomes half to 10 g. And in the fifth 12 days, from 10 g it becomes half to 5 grams. So 5 times it became half.
5 x 12 ( days)= 60 days
A blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.
<h3>
What is Schwarzschild radius?</h3>
Schwarzschild radius is defined as the radius below which the gravitational pull between a body's particles causes it to collapse gravitationally.
It can also be defined as the radius of a collapsing astronomical object at which gravitational forces necessitate an escape velocity greater than the speed of light, resulting in a black hole.
The Schwarzschild radius is solely determined by the object's mass, hence the larger the mass, the larger the Schwarzschild radius.
Thus. a blue whale will have the largest Schwarzschild radius, as it has larger mass than the other. Thus option A is correct.
