Explanation :
Calcium chloride is an ionic compound because calcium element is a metal and chloride element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The nomenclature of ionic compounds is given by:
1. Positive ion is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
The charge on calcium is (+2) and the the charge on chloride is (-1). The charges are not balanced. Thus they combine and their charges are exchanged and written in simplest whole number ratios to give neutral .
Hence, the formula of the compound calcium chloride will be
a. How many grams of Na20 are produced when 57.5 g of Na
reacts ?
b. If you have 18.0 g of Na, how many grams of O2 are
required for reaction?
c. How many grams of O2 are needed in a reaction that
produces 75.0 g of Na2O?
Answers
Answer:
Explanation:
a )
4Na(s) + O₂(g) - - 2Na₂O(s)
4 x 23g 32g 2x62
92 g of Na produces 124 g of Na₂O(s)
57.5 g of Na produces (124 / 92) x 57.5
= 77.5 g of Na₂O(s)
b )
92 g of Na requires 32 g of O₂
18 g of Na requires ( 32 / 92 ) x 18
= 6.26 g of O₂
c )
128 g of Na₂O(s) requires 32 g of O₂
75 g of Na₂O(s) requires ( 32 / 128 ) x 75
= 18.75 g of O₂

Isotopes refer to different forms of the same element having identical number of protons but varying number of neutrons. Examples of isotopes with equal number of protons and neutrons include Carbon-12 and Deuterium. These isotopes, including the unstable ones termed as 'radioactive isotopes', contribute significantly to an element's atomic mass.
Explanation:
Isotopes are alternate forms of the same element that have the same number of protons but a different number of neutrons. When an isotope has the same number of protons and neutrons, it can be found in lighter elements such as carbon and hydrogen. A good example is the isotope Carbon-12 (with six protons and six neutrons) which is a common isotope of carbon found on Earth. Another example is Hydrogen-2 or Deuterium (with one proton and one neutron). This is because the number of protons (also known as the atomic number) identifies an element - regardless of the number of neutrons.
The presence of isotopes is important in elements as they contribute to the overall atomic mass and affect the behavior of the element. For instance, radioactive isotopes, such as Carbon-14, are unstable and can emit subatomic particles or energy to attain a lower potential energy state, which explains why they're used in radioactive dating methods.
It's worth noting that the number of neutrons in an atom can vary and is not necessarily equal to the number of protons, especially in heavier elements.

Liver cells, which require a high amount of energy, contain large numbers of mitochondria, the organelles responsible for energy production in the form of ATP.
Explanation:
The cell organelles that you would expect to appear in large numbers in liver cells, which require a great deal of energy, are mitochondria. Mitochondria, often referred to as the 'powerhouses of the cell, are responsible for producing a molecule called adenosine triphosphate (ATP), which is the main source of cellular energy. Therefore, cells that require a lot of energy, like liver cells, tend to have many mitochondria in order to meet their energy demands.
