A solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral. Why?
Answer:
Because when you find the pH it comes out to be 7; 7 is neutral.
Explanation:
pH=-log(H3O+)
- Hope this helped! Please let me know if you need further explanation.
A solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral as on calculating pH, it comes out to be 7.
What is pH?pH, often known as acidity in chemistry, has historically stood for "potential of hydrogen" (as well as "power of hydrogen"). It refers to a scale used to describe how basic or how acidic an aqueous solution is. When compared to basic or alkaline solutions, acidic solutions—those with higher hydrogen (H+) ion concentrations—are measured with lower pH values.
Where [H+] represents the solution's equilibrium molar concentration of H+ (mol/L). Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At 25 °C, fluids with a pH value of 7 are neutral. A solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral as on calculating pH, it comes out to be 7.
pH = -log[H⁺]
= -log[1.00 x 10⁻⁷]
= 7
Therefore, a solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral as on calculating pH, it comes out to be 7.

According to Reference Table Adv-8, which of the following is the strongest Brönsted-Lowry acid?
1.HS-
2.H2S
3.HNO2
4.HNO3
Answer:
HNO3
Explanation:
The ability of an acid to act as a Brownstead-Lowry acid depends on it's proton donation ability.
A Brownstead-Lowry acid is a specie that donates hydrogen ions in solution.
Considering all the chemical species listed among the options, HNO3 has the greatest hydrogen donation ability. It then follows that HNO3 is the strongest Brownstead-Lowry acid among the species listed.

Describe how alleles and genes are related.
Answer:
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. Chromosomes occur in pairs so organisms have two alleles for each gene one allele in each chromosome in the pair.
Of the following chemical properties , which one is not one that Covalent compounds DO NOT have ?
a
They share electrons between their elements.
b
They have weaker bonds.
c
They have relatviely higher melting and boiling points.
d
Many of these compounds are usallly liquids or gases at room temperature.
Answer:
D. They are usually liquids or gases at room temperature.
Explanation:
Covalent compounds have covalent bonds, meaning that they share electrons between elements and have relatively higher melting melting and boiling points due to the strength of their bonds. However covalent bonds are weaker than ionic bonds which is why B is correct. D is the only incorrect one because it is incorrect and contradicts point C. If a substance has a high melting/boiling point than it is much more likely to be solid at room temperature because of the high temperature it needs to pass in order to be a liquid or gas.

Calculate the volume that 12.5 g of Co, gas will occupy at a
temperature of 40°C and a pressure of 1.20 atm.
The volume of the gas can be calculated using the ideal gas equation. The volume of 12.5 g Co gas at 40° C or 313 K and at 1.2 atm is 4.4 L.
What is ideal gas law?Ideal gas law is the combination of all the gaseous laws, relating the temperature, pressure, volume and number of moles of gas as written below:
PV = nRT
here, n is the number of moles and R be the universal gas constant equal to 0.082 L atm/ (K mol), T be the temperature in kelvin and p is the pressure in atm and finally v is the volume in L.
Given that the weight of Co is 12.5 g. Its atomic mass is 58.5. Thus number of moles of Co gas is 12.5/58.5 = 0.21 moles.
Now, apply the values of pressure, temperature and number of moles to the ideal gas equation as follows:
V = nRT/P
= (0.21 × 0.082 L atm/ (K mol) × 313 K ) /1.21 atm
= 4.49 L.
Therefore, the volume of 12.5 g Co gas at 313 K and at 1.2 atm is 4.49 L.

What is the volume of 9.5 g fluorine gas, F2, at STP?
Answer:
5.6L
Explanation:
At STP, the pressure and temperature of an ideal gas is
P = 1 atm
T = 273.15k
Volume =?
Mass = 9.5g
From ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = ideal gas constant =0.082J/mol.K
T = temperature of the ideal gas
Number of moles = mass / molar mass
Molar mass of F2 = 37.99g/mol
Number of moles = mass / molar mass
Number of moles = 9.5 / 37.99
Number of moles = 0.25moles
PV = nRT
V = nRT/ P
V = (0.25 × 0.082 × 273.15) / 1
V = 5.599L = 5.6L
The volume of the gas is 5.6L

Answer:
A.
Explanation:
Sulfur has 6 valence electrons, therefore has 6 dots.
- Hope that helps! Please let me know if you need further explanation.
The correct option is A.
What is a dot diagram?
A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom.
Why do we use electron dot diagrams?These diagrams are helpful because they allow us to show how atoms are connected, and when coupled with Valence Shell Electron Repulsion Theory (VSEPR), we can use Lewis structures to predict the shape of the molecule.

A HALF-LIFE IS "HALF" OF THAT TIME PERIOD!
So if the radiation goes for 6 years the half-life is 6 divided by two which gives you 3 years!
The rest however have a longer half-life...
Because they all end at 14 yrs so their half-life in 7 years!

What is the volume of solution (in mL) produced when 91.80g of Mg(OH)2 are used
to produce a 0.7M solution? Record your answer to 1 decimal places.
Answer: The volume of solution is 2248 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute
[tex]V_s[/tex] = volume of solution in ml
moles of [tex]Mg(OH)_2[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{91.80g}{58.32g/mol}=1.574mol[/tex]
Now put all the given values in the formula of molality, we get
[tex]0.7=\frac{1.574\times 1000}{V_s}[/tex]
[tex]V_s=\frac{1.574\times 1000}{0.7}=2248ml[/tex]
Therefore, the volume of solution is 2248 ml
