The compound will have a triple bond.
Explanation:
A compound which consists of carbon and hydrogen atoms is known as a hydrocarbon.
Alkanes, alkenes and alkynes are all hydrocarbons.
- General chemical formula of an alkane is . In an alkane molecule, all the atoms will be bonded through single bonds.
For example, is propane.
- General chemical formula of an alkene is . An alkene molecule will have atleast one double bond between two carbon atoms.
For example, is ethene.
- General chemical formula of an alkyne is . An alkyne will have atleast one triple bond between two carbon atoms.
For example, is propyne.
Thus, we can conclude that out of the given options will have a triple bond.
Answer:
The mass of NaHCO3 required is 235.22 g
Explanation:
*******
Continuation of Question:
2NaHCO3(s) + H2SO4(aq) → Na2SO4(aq) + 2CO2(g) + 2H2O(l)
You estimate that your acid spill contains about 1.4 mol H2SO4. What mass of NaHCO3 do you need to neutralize the acid?
********\
The question requires us to calculate the mass of NaHCO3 to neutralize the acid.
From the balanced chemical equation;
1 mol of H2SO4 requires 2 mol of NaHCO3
1.4 would require x?
Upon solving for x we have;
x = 1.4 * 2 = 2.8 mol of NaHCO3
The relationship between mass and number of moles is given as;
Mass = Number of moles * Molar mass
Mass = 2.8 mol * 84.007 g/mol
Mass = 235.22 g
Alpha particles are relatively heave and can be stopped by a sheet of paper.
Answer:
56 L
Explanation:
We're dealing with a gas in this problem. We may, therefore, apply the ideal gas law for this problem:
We now that we have a constant pressure. Besides, R, the ideal gas law constant, is also a constant number. Let's rearrange the equation so that we have all constant variables on the right and all changing variables on the left:
This means the ratio between volume and temperature is a constant number. For two conditions:
Given initial volume of:
Convert the initial temperature into Kelvin:
Convert the final temperature into Kelvin:
Rearrange the equation for the final volume:
I believe the answer would be 16.8
