b) 200.00 kg - 199.0 kg =
c) 25 L - 3.0 L =
d) 0.67 cm + 2.0 cm + 0.090 cm =
e) 104.5 g + 0.40 g =
The answer will be 0.75 gram, 1 kilo-gram, 22 L, 2.76 cm, and 104.9 gram.
A metric unit with mass and weight equal to approximately 15.432 grains, or one-thousandth of a kilo-gram, is called a gram.
Calculation of given question.
a) 7 gram - 3.5 gram - 2.75 gram = 0.75 gram
b) 200.00 kg - 199.0 kg = 1 kilo-gram
c) 25 L - 3.0 L = 22 L
d) 0.67 cm + 2.0 cm + 0.090 cm = 2.76 cm
e) 104.5 g + 0.40 g = 104.9 gram

Answer:
Explanation:
There is a fundamental length, the Planck length. It is the length that light (a photon) travels in a unit of time called the Planck time and conforms to the way to measure length in general, as given by the equation
L = ct
Where L is length (or distance), c the speed of light (3 X 10^8 meters/sec), and t the time the light travels in. The Planck length is exceedingly small (magnitude 10^-35 meters because the Planck time is short (10^-44 sec)
The Planck length, or any length based on the speed of light, is not subject to the imprecision we would find by measurement with a physical ruler, for example, because a ruler can expand or shrink or be bent or warped, etc.
Rather, length based on c (in a vacuum) is constant. This concept is another gift from Einstein’s theory of special relativity. It’s also the central concept in spacetime, though it would take some explaining for me to say why it is so.
Answer:
The correct answer is A.
Explanation:
The periodic table published by Mendeleev in 1869 was the first periodic table to group the elements. Based on the hypothesis that the properties of the elements are a periodic function of their atomic weights, he placed in the table all the elements known up to that moment, which became 63 elements, ordering them in such a way that the elements belonging to the same family appear in the same vertical line. The elements were arranged in the increasing order of their atomic masses.

What are two properties of most nonmetals? The two properties of most nonmetals are high ionization energy and poor electrical conductivity. The answer is number 1. The rest of the choices do not answer the question above.
b. the reaction rate does not change.
c. the reaction rate increases.
d. the equilibrium shifts.
Copper and Iron are two metals that can lose different numbers when they react with another molecule.
Therefore, copper and Iron are two metals that can lose different numbers when they react with another molecule.
