Can carbon and hydrogen form double bonds between them?
Answers
Answer:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

Which statement best explains how the conditions identified in Part A affect the availability of opal?
A
Weathering processes no longer occur in Australia, so no new opal is formed.
B
Gems do not need an exact combination of elements or minerals to form, so opal forms more easily.
C
Opal formation occurs over large periods of time, so the number of opal deposits is limited.
D
Volcanoes in Australia no longer provide high temperatures and pressures, so no new opal is formed.

How many milliliters of 4.00 M NaOH are required to exactly neutralize 50.0 milliliters of a 2.00 M solution of HNO3 ?
Answers
Answer: The volume of [tex]NaOH[/tex] required is 25.0 ml
Explanation:
According to the neutralization law,
[tex]n_1M_1V_1=n_2M_2V_2[/tex]
where,
[tex]n_1[/tex] = basicity [tex]HNO_3[/tex] = 1
[tex]M_1[/tex] = molarity of [tex]HNO_3[/tex] solution = 2.00 M
[tex]V_1[/tex] = volume of [tex]HNO_3[/tex] solution = 50.0 ml
[tex]n_2[/tex] = acidity of [tex]NaOH[/tex] = 1
[tex]M_1[/tex] = molarity of [tex]NaOH[/tex] solution = 4.00 M
[tex]V_1[/tex] = volume of [tex]NaOH[/tex] solution = ?
Putting in the values we get:
[tex]1\times 2.00\times 50.0=1\times 4.00\times V_2[/tex]
[tex]V_2=25.0ml[/tex]
Therefore, volume of [tex]NaOH[/tex] required is 25.0 ml
The volume of 4.00 M NaOH is required to exactly neutralize 50.0 ml of a solution of a 2.00 M solution of [tex]HNO_3[/tex] is 25.0 ml.
What is [tex]HNO_3[/tex]?[tex]HNO_3[/tex] is nitric acid also known as the spirit of niter. It is colorless in its original form but appears yellow-colored.
By the neutralization law
[tex]n_1M_1V_1 = n_2M_2V_2[/tex]
n1 = 1
M1 = 2.00
M2 = 4.00
V1 = 50.0 ml
n2 = NaOH = 1
Putting the value in the formula
[tex]1 \times 2.00 \times 5.00 ml = 1 \times 4.00 \times V_2\\\\V_2 = 25.0\; ml[/tex]
Thus, the volume of NaOH required is 25.0 ml.

How many grams of magnesium
sulfate (MgSO4) are dissolved in
0.965 L of a 0.0575 M solution?
Molar Mass Mg: 24.30 g/mol
Molar Mass S: 32.06 g/mol
Molar Mass O: 16.00 g/mol
Answers
Explanation:
Concentration question....
0.965L x (0.0575 mol MgSO4 / 1L) x (120.4g MgSO4 / 1 mol MgSO4) = 6.68g MgSO4
The concept molarity is used here to determine the grams of magnesium sulfate dissolved in 0.965 L of a 0.0575 M solution. The mass of magnesium sulfate in grams is 6.68 g.
What is molarity?The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is generally represented by the unit mol/L. The equation used to calculate the molarity is:
Molarity = Number of moles of the solute / Volume of the solution in litres
The molar mass of MgSO₄ = 120.36 g/mol
We have 0.0575 M solution.
That is 0.0575 mol/L × 120.36 g/mol = 6.9207 g/L
Here we want mass in 0.965 L. So the mass is:
Mass = 0.965 L × 6.9207 g/L = 6.68 g
Thus the mass in grams of magnesium sulfate is 6.68 g.

an unknown gas has a pressure of 121.6 kPa, a volume of 31 L and a Temperature of 256K. How many moles of gas
are there?
Answers
Answer:
0.031moles
Explanation:
ok so it would help if I knew the marks but 1 mole = 1000L so if the volume was 31L then if you convert you will get that answer
The moles of gas at the given sample of gas is 1.7 moles.
What is ideal gas equation?Ideal gas equation gives idea about the behavior of gas at different condition & represented as:
PV = nRT, where
P = pressure = 121.6 kPa = 1.2 atmV = volume = 31 Ln = moles = ?R = universal gas constant = 0.082 L.atm / K.molT = temperature = 256KOn putting all these values, we get moles as:
n = (1.2)(31) / (0.082)(256) = 37.2 / 20.9
n = 1.7 moles
Hence required moles of gas is 1.7 mole.
