Magnesium has 2 valence electrons.
When the metal was added to the calorimeter, some of the water splashed out. How would the loss of water in the Styrofoam cup affect the final temperature
The final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.
A styrofoam cup is an insulated material. A styrofoam cup prevents heat gain or looses from the cup. Heat is gained by the water inside the styrofoam cup. The cup prevents exchange of energy with the environment.
When water is lost from the styrofoam cup, the final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

1. A substance which takes the shape and volume of its container is a?
Solid
Liquid
Gas
Crystal
Answer:
Liquid
Explanation:
Liquid
Answer:
Gas
Explanation:
Gas takes the shape and volume of its container because it doesn't have a definite shape or volume.
Liquid is wrong because it takes the shape of its container, but has a definite volume.
Gas is wrong because it has a definite shape and volume.
Crystal is definitely wrong.
Calculate the normality of a solution made by diluting 12 g of H3PO4 with water to produce 250.0 mL of solution.
The normality of a solution made by diluting 12 g of H3PO4 with water to produce 250.0 mL of solution is 1.47 eq/L.
The normality of a solution is;
N = Mass of solute in grams/volume of solution in litres × Equivalent weight
Mass of solute = 12 g
volume of solution = 250.0 mL or 0.25 L
Equivalent weight = Molar mass of H3PO4/n
n = Number of hydrogen ions in H3PO4
Equivalent weight = 98 g/mol/3 = 32.7
Substituting values;
N = 12/0.25 × 32.7
N = 1.47 eq/L

The density of gold is 19. 3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ). 25 cm3. 67 cm3 1. 48 cm3 2. 50 cm3.
Answer:
0.67 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 13 g
density = 19.3 g/cm³
We have
[tex]volume = \frac{13}{19.3} \\ = 0.673575...[/tex]
We have the final answer as
0.67 cm³Hope this helps you

Pls help me!! Explain how the N:Z ratio can help predict the type of radiation Zr-85 and Zr-95 emit.
No links pls
Based on N:Z ratio, Zr-85 is expected to decay by positron emission. Zr-95 is expected to emit beta particles in a beta decay.
The N:Z ratio determines the stability of a nucleus. If a nucleus has N:Z ratio >1.5 or <1.0, such a nucleus is unstable and will undergo radioactive decay. The aim of such a decay is to attain a favorable N:Z ratio.
For Zr -85, the N:Z ratio is 1.1 while the N:Z ratio of Zr-95 is 1.4. Zr -85 is expected to decay by positron emission which increases the N:Z ratio. For Zr-95, the nucleus tends to undergo processes that decrease the N:Z ratio such as beta emission.

Which molecule has the same empirical formula as molecular formula?
A. CH3COOH
B. C2H5OH
C. C2H4
D. C4H10
and what is the working
the answer is C ( i think )
The correct statement which has the same empirical formula as molecular formula is "CH3COOH".
What is empirical formula?A chemical compound's empirical formula is a representation of the simplest whole number ratio between its constituent parts.
What is molecular formula?The molecular formula is a depiction of the compound's actual whole number ratio between its constituent parts.
To put it another way, molecular formulas tell you how many atoms of each element are in a compound, whereas empirical formulas tell you the simplest or most reduced ratio of components.
Acetic acid has the molecular chemical formula CH3COOH. In the order C: H: O, the true whole number ratio is 2: 4: 2. In the order C: H: O, the smallest simple whole number ratio is 1: 2: 1. As a result, acetic acid's empirical formula is CH2O.
Hence, the correct option is A.

which elements from the periodic table are the least reactive
Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:
