Answer:</h3>
2Fe(s) + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂(g)
<h3>
Explanation:</h3>
The equation for the reaction between iron metal and sulfuric acid is given by;
Fe(s) + H₂SO₄ → Fe₂(SO₄)₃ + H₂(g)
We are supposed to balance the equation:
What do we mean by balancing a chemical equation?
- Balancing a chemical equations means that we want to make sure the number of atoms of each element is the same on both sides of the equation.
How is balancing done?
- Balancing of chemical equations is try and error process that is done by putting appropriate coefficients on the reactants and products to equate the number of atoms of each element.
Why are subscripts on the compounds not changed?
- Subscripts in a compound show the actual number of atoms of each element in the compound and therefore can never be altered with because it will distort the chemical compound.
Why is it necessary to balance chemical equations?
- Chemical equations are balanced for them to obey the law of conservation of mass.
- According to this law, the mass of the reactants should be equal to the mass of products, which is achieved through balancing an equation.
What is the required balanced equation?
- The equation given can be balanced by putting the coefficients 2, 3, 1, 3 in that order on the reactants and products.
- Therefore, the balanced chemical equation is;
2Fe(s) + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂(g)
Answer:
Lithium and Sodium
Explanation:
Losing and electron in natural setting is characterizes of elements in group one. These are elements known as the alkaline earth metals. They are the most electropositive elements on the periodic table.
These elements ionize by losing an electron yin their outermost shell to attain the configuration of the nearest noble gas. These elements are usually found in combined and rarely seen in uncombined state principally due to their very reactive nature.
Sodium naturally would ionize by losing one electron. Other elements capable of this even at a better rate because they are more electropositive are potassium and lithium. Both are also group one alkaline metals

Answer:
Explanation:
During the seventeenth and especially eighteenth centuries, driven both by a desire to understand nature and a quest to make balloons in which they could fly (Figure 1), a number of scientists established the relationships between the macroscopic physical properties of gases, that is, pressure, volume, temperature, and amount of gas. Although their measurements were not precise by today’s standards, they were able to determine the mathematical relationships between pairs of these variables (e.g., pressure and temperature, pressure and volume) that hold for an ideal gas—a hypothetical construct that real gases approximate under certain conditions. Eventually, these individual laws were combined into a single equation—the ideal gas law—that relates gas quantities for gases and is quite accurate for low pressures and moderate temperatures. We will consider the key developments in individual relationships (for pedagogical reasons not quite in historical order), then put them together in the ideal gas law
