Answer:
I believe that would be methane! I hope this helps you!
Answer:
methane
Explanation:
The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). Natural gas also contains smaller amounts of natural gas liquids (NGL, which are also hydrocarbon gas liquids), and nonhydrocarbon gases, such as carbon dioxide and water vapor.The main component in natural gas is methane. It also has ethane, propane, butane, hydrocarbons.

What differences between snow and sand
Answer:
difference is the temperature at which they melt. Snow melts at 0°C, whereas sand melts at about 1600°C!

what is the resonance structure of xef4
Answer:
The Lewis structure for XeF4 has a total of 36 valence electrons. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell). We also need to check to make sure we only used the number of available valence electrons we calculated earlier (no more, no less).

Silicon dioxide is a solid at room temperature and methanol is a liquid. What substance has the higher melting point?
Answer:
methanol because it is liquid at room temperature which means that it melts at a lower temperature
Silicon dioxide is a solid at room temperature and methanol is a liquid. Silicon dioxide has a higher melting point than methanol because silicon dioxide is solid, and with increasing temperature, it will melt.
What is a melting point?Melting point is that point or temperature at which the solid items are converted into liquid, and it changes their atoms and the atoms lose their compactness.
Here, two compounds are given, Silicon dioxide and methanol, the first one is solid at room temperature, so it will need more temperature to melt down and methanol is still liquid at room temperature, so its melting point is low.
Thus, methanol is a liquid while silicon dioxide is a solid at ambient temperature. Because silicon dioxide is a solid and melts at greater temperatures, it has a higher melting point than methanol.

How many Mg atoms are there in 0.764 moles of Mg?
atoms
Answer:
1.135986935e+39
Answer:
[tex]\boxed {\boxed {\sf 4.60 \times 10^{23} \ atoms \ Mg}}[/tex]
Explanation:
We are asked to find how many atoms of magnesium are in 0.764 moles of magnesium.
We convert moles to atoms using Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of magnesium. So, there are 6.022 × 10²³ atoms of magnesium in 1 mole of magnesium.
Convert using dimensional analysis and set up a conversion factor using Avogadro's Number.
[tex]\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]
We are converting 0.764 moles of magnesium to atoms, so we multiply by this value.
[tex]0.764 \ mol \ Mg *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]
The units of moles of magnesium cancel.
[tex]0.764 *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 }[/tex]
[tex]0.764 *6.022 \times 10^{23} \ atoms \ Mg[/tex]
[tex]4.600808 \times 10^{23} \ atoms \ Mg[/tex]
The original value of moles (0.764) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 0 in the thousandth place tells us to leave the 0 in the hundredth place.
[tex]4.60 \times 10^{23} \ atoms \ Mg[/tex]
0.764 moles of magnesium contains approximately 4.60 × 10²³ atoms of magnesium.

adjoa's gross salary for last month was ghs 4687.24. if ghs 421.78 was deducted from adjoa's salary pay,how much take home pay did adjoa earned this past month?
Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.
Given the following data:
Adjoa's gross salary = Ghs. 4687.24.Deduction = Ghs. 421.78Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).
On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.
To find how much take home pay Adjoa earned this past month:
[tex]Take\;home = Gross\;salary - deduction\\\\Take\;home = 4687.24 - 421.78[/tex]

Answer:
24.9
Explanation:
-
Acetone [(CH3)2C=O], a simple ketone is commonly used to make products like nail polish remover and paint remover. Draw a picture showing the orbitals involved in the and bonds including its lone pairs.
Carbon and oxygen atoms in (CH3)2C=O form sigma and pi bonds. The pi bonds are formed using unhybridized p orbitals.
Acetone (CH3)2C=O contains the carbonyl group (C=O). Carbon is bonded to oxygen via a double bond as shown in the orbital structure. The carbon atom is also bonded to two methyl groups.
The central carbon atom is sp2 hybridized as well as the oxygen atom in acetone. The pi bond is formed by the overlap of unhybridized p orbitals on both carbon and oxygen atoms. The sigma bonds are formed using the sp2 hybridized carbon atoms on carbon and oxygen.
