Consider the following reaction: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2 How many L of CO2 would be produced from the complete reaction of 25 mL of 0.833 mol/L HC3H3O2 with excess NaHCO3 at STP?

0.466 L (or 0.46648 L if not rounding)

Explanation:

Hey so this problem is just testing your knowledge of stoichiometry with volume analyses and such.

For this first we notice that NaHCO3 is excess so we don't care about it since it doesn't affect the final product.

So we start by finding the moles of acetic acid (Hc2h3o2) because we remember

Molarity=moles/litres

0.833=x/(25/1000)we divide by thousand to convert ml to litres

x= 0.020825 moles acetic acid x 1mol Co2/1mol acetic acid (this is just using molar ratio to go from moles of acetic acid to moles of co2)

x= 0.020825 mol CO2

Now since it is at STP we know molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas.

So we just multiply 0.020825mol Co2 x 22.4L/1mol Co2 = 0.46648L or 0.466L

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.
