Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)

<h3>Further explanation</h3>

Given

Word equation

Required

Balanced equation

Solution

Convert to skeleton equation

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + NaNO₃(aq)

Balanced equation

Give a coefficient

Na₂C₂O₄(aq) + aPb(NO₃)₂⇒bPbC₂O₄(s) + cNaNO₃(aq)

Make an equation

C, left = 2, right =2b⇒2b=2⇒b=1

Na, left = 2, right = c⇒c=2

O, left = 4+6a, right = 4b+3c⇒4+6a=4b+3c⇒4+6a=4.1+3.2⇒6a=6⇒a=1

The equation becomes :

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)

Which liquid has the highest vapor pressure at 75°C?

Temka [501]

Answer:

1) Ethanol

Explanation:

If we will have interactions we will need more energy to break them in order to go from liquid to gas. If we need more energy, therefore, the temperature will be higher.

In this case, we can discard the propanone because this molecule don't have the ability to form hydrogen bonds. (Let's remember that to have hydrogen bonds we need to have a hydrogen bond to a heteroatom, O, N, P or S).

Then we have to analyze the hydrogen bonds formed in the other molecules. For ethanol, we will have only 1 hydrogen bond. For water and ethanoic acid, we will have 2 hydrogen bonds, therefore, we can discard the ethanol.

For ethanoic acid, we have 2 intramolecular hydrogen bonds. For water we have 2 intermolecular hydrogen bonds, therefore, the strongest interaction will be in the ethanoic acid.

The closer boiling point to the 75ºC is the ethanol (boiling point of 78.8 ºC) therefore these molecules would have enough energy to break the hydrogen bonds and to past from liquid to gas.

BRAINLIESTTT ASAP!!!! PLEASE HELP ME :)

Elan Coil [88]

Answer:

1s² 2s²2p³

Explanation:

If the atom has seven electrons, it is Element 7 (nitrogen).

In the Periodic Table, you count the electrons in all the subshells up to

No. 7.

In the first Period, you have filled the 1s level (2 electrons).

In the second Period, you have filled the 2s subshell (2 electrons) and put three electrons in the 2p subshell.

Thus, the electron configuration is

1s² 2s²2p³

Note how the superscripts tell you the number of electrons in each subshell: 2 + 2 + 3 = 7.

Hey! I need a simple connotation of how glowsticks glow. Please and thank you.

LenaWriter [7]

Answer:

simple

Explanation:

The glow stick's outer plastic tube holds a solution of an oxalate ester and an electron-rich dye along with a glass vial filled with a hydrogen peroxide solution. ... Glow sticks light up when oxalate esters react with hydrogen peroxide to form a high-energy intermediate
