Which set up would correctly complete the work for determining how many moles of NaOH will be produced if 10.5 grams of water (H

2O) is used?

Answer:

B: 2 mol NaOH/2 mol H2O

Explanation:

The reaction equation is;

H2SO4 + 2NaOH = Na2SO4 + 2H20

Now, to know how many moles of NaOH will be produced for 10.5 grams of water (H2O) used, and since the molar mass of H2O is 18.02 g/mol and number of moles attached to H2O and NaOH in the reaction are both 2 we will have;

10.5g H2O × 1 mol H2O/18.02 g H2O × 2 mol NaOH/2 mol H2O

Thus correct answer is option B

Why does a star expand into a red giant?​
devlian [24]

Answer:

"Hydrogen is still available outside the core, so hydrogen fusion continues in a shell surrounding the core. The increasingly hot core also pushes the outer layers of the star outward, causing them to expand and cool, transforming the star into a red giant."

FOR 100 POINTS, IF INCORECT...
Lilit [14]

Answer:

#1

Heat transfer occurred in the room through radiation

This is where heat is transmitted through vacuum or an empty space from a point to another.

#2

From the furnace, the air molecules nearer the region gained higher kinetic energy hence colliding with other molecules in the room. This causes a positive temperature gradient which causes an increment change in temperature in the room.
