Answers
mass before reaction = mass after reaction
Mg + O = MgO
Mg + 32 = 80.6
Mg = 80.6 - 32 = 48.6 (a)

If you are given a 0. 32 g piece of sodium metal to react with water, how many moles of hcl would it take to neutralize the sodium hydroxide produced?.
Answers
Answer:
.0139
Explanation:
The number of moles of HCl would take to neutralize the sodium hydroxide produced is equal to 0.0139 moles.
What is a neutralization reaction?A neutralization reaction can be defined as a chemical reaction in which an acid and base react with each other to prepare salt and water.
When HCl reacts with NaOH and the resulting salt is sodium chloride and water.
HCl + NaOH [tex]\longrightarrow[/tex] NaCl + H₂O
The chemical reaction, chemical reaction of sodium metal and water gives hydrogen gas and sodium hydroxide:
[tex]2Na+ 2H_2O \longrightarrow 2NaOH + H_2[/tex]
Given the amount of sodium metal = 0.32 g
The moles of sodium metal = 0.32/23 = 0.0139 moles
If the 2 moles of sodium produce sodium hydroxide = 2 mol
The 0.0139 moles of sodium will produce NaOH = 0.0139
Therefore, 0.0139 moles of HCl is required to neutralize 0.0139 moles of NaOH.

Oxygen gas occupies a volume of 95 ml at 305 k. what volume will it occupy at 550 k?
Answers
The new volume of the oxgen gas as the temperature is increased is 171.3ml.
Given the data in the question;
Initial olume of oxygen gas; [tex]V_1 = 95ml = 0.095L[/tex]Intial temperature; [tex]T_1 = 305K[/tex]Final temperature; [tex]T_2 = 550K[/tex]Final volume of oxygen gas; [tex]V_2 = \ ?[/tex]Charles's lawCharles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.
It is expressed as;
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]
To determine the new volume of the oxgen gas as the temperature is increased, we substitute our given values into the expression above.
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}\\ \\ \frac{0.095L}{305K} = \frac{V_2}{550K}\\\\V_2 * 305K = 0.095L * 550K\\\\V_2 * 305K = 52.25LK\\\\V_2 = \frac{52.25LK}{305K} \\\\V_2 = 0.1713L\\\\V_2 = 171.3ml[/tex]
Therefore, the new volume of the oxgen gas as the temperature is increased is 171.3ml.

A meteorite is found to contain two isotopes of element X, X-12, and X-14. Experimental analysis determined 95% of the element is isotope X-12, whereas 5% of the element is isotope X-14. What is the average atomic mass of element X?
Select one:
12.0 amu
14.0 amu
12.1 amu
13.0 amu
Answers
Considering the definition of atomic mass, isotopes and atomic mass of an element, the atomic mass of the element is 12.1 amu.
Definition of atomic massFirst of all, the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus of a chemical element.
Definition of isotopeThe same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element.
Definition of atomic massOn the other hand, the atomic mass of an element is the weighted average mass of its natural isotopes.
In other words, the atomic masses of chemical elements are usually calculated as the weighted average of the masses of the different isotopes of each element, taking into account the relative abundance of each of them.
Atomic mass of the element in this caseIn this case, the first isotope has an atomic mass of 12 amu and a percent natural abundance of 95 %. The second isotope has an atomic mass of 14 amu and a percent natural abundance of 5 %.
Then, the average mass can be calculated as:
12 amu×0.95 + 14 amu×0.05= 12.1 amu
Finally, the atomic mass of the element is 12.1 amu.

explain how stalacitites and stalagmites are formed
Answers
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up. They are formed from condensation inside a cave, dripping off the ceiling.

The microscopes used today are just like the ones used by Leeuwenhoek and Hooke. True or false
Answers
Answer:
False
Explanation:
While we do know that A. Leeuwenhoek used a simple microscope that consisted of only 1 lens, Hooke used a compound microscope. Although, after trying a compound microscope, Hooke found out that it strained his eyes and continued to use a simple microscope for his Micrographia.
Thus, we can say that the (compound) microscopes used today are different than the (simple) microscope used by Hooke and Leeuwenhoek.
