16. Keesha performed a chemical reaction, and the products looked quite
different from the reactants. She knew the amount of matter had not
changed due to the law of conservation of mass. According to the law of
conservation of mass, what happens in a chemical reaction? *
Answer:
it's the third one
Explanation:
matter can't change, but mass can differ
1Kr + 3 F2 → 1KrF6
2. How many moles of fluorine are required to
produce 3.0 grams of KrFo?
Answer: 0.045 moles of [tex]F_2[/tex] will be required to produce 3.0 grams of [tex]KrF_6[/tex].
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} KrF_6=\frac{3.0g}{198g/mol}=0.015moles[/tex]
The balanced chemical equation is:
[tex]Kr+3F_2\rightarrow KrF_6[/tex]
According to stoichiometry :
1 mole of [tex]KrF_6[/tex] is produced by = 3 moles of [tex]F_2[/tex]
Thus 0.015 moles of [tex]KrF_6[/tex] will be produced by=[tex]\frac{3}{1}\times 0.015=0.045moles[/tex] of [tex]F_2[/tex]
Thus 0.045 moles of [tex]F_2[/tex] will be required to produce 3.0 grams of [tex]KrF_6[/tex].

Earth is removed from the top to reveal the coal. Which type of coal mine does this describe? undersea subterranean drill strip
Answer:
Strip
Explanation:
Strip mining removes Earth in long strips from the top to reveal the coal. This earth to be removed is known as 'overburden'. The overburden from the first strip is referred to as out-of-pit dumping. Strip mining is a part of surface mining.
Strip mining destroys forests, landscapes, forests and wildlife habitats as trees and plants are removed from the mining area.
Therefore,
this describes the Strip coal mine.
Answer:
strip Mining.

There are some climates in which there are no living things. true or false
Answer:
True
Explanation:
There are some climates in which there are no living things. The average of the weather is the climate.
What is climate ?Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years.
Every element of our life is impacted by the climate, including our food supplies, transportation systems, clothing choices, and vacation destinations. It significantly affects our future, our health, and our means of subsistence. Climate is the long-term trend of the weather in any given location.
As an illustration, you can anticipate snow in the Northeast in January or hot and muggy weather in the Southeast in July. Climate is this. Extreme values, such as record-breaking high temperatures or heavy rainfall, are also part of the climatic record.
Thus, there are some climates in which there are no living things.

what is the electrical charge of an atom
A geologist finds an area with a lot of slate, a type of metamorphic rock, on the surface of the land. What might this indicate about Earth's history in this area?
Answer:
Explanation:
Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied being so far underground. Therefore, creating what we now know as Slate.

Explanation:
Use Avogadro's number that states that there are 6.022 x 10^23 particles in one mole:
12 mol O x (6.022 x 10^23) atoms = 7.23 x 10^24 atoms
element with same number of valence electrons as iodine:
Fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) all have the same number of valence electrons.
What is valence electron ?
Valence is nothing but a number of electrons in an atom which may either lose or gain to attain the nearest noble gas or inert gas state of electronic configuration.
The valence electrons are contain more energy compared to the electrons present in inner orbits, so they are the part of chemical reaction.
The number of valence electrons of an atom helps to determine a specific chemical properties, like valence or valency, the formation of bonds with other elements, gives an idea of how readily the atoms can form bonds.
Some major characteristics of a valence electron include the valence electron exists only in the outermost electron shell, exist in the inner shell of a transition metal, the atom with the shell of valence electrons are chemically inert, either absorb or release energy in the form of a photon, determine electrical conductivity .
