Your teacher directs you to combine two liquid substances into a flask. after you combine them, you notice that the flask feels
adelina 88 [10]

Answer : The correct option is (A).

Explanation :

  • Endothermic reaction : When two liquids are combine into a flask, then the flask feels cold when we touch it because the system absorbed heat from the surrounding.

In general, endothermic process absorbs heat and cool the surrounding.

  • Exothermic reaction : When two liquids are combine into a flask, then the flask feels hot when we touch it because the system released heat into the surrounding.

In general, exothermic process releases heat and rise the temperature of surrounding.

If 24.1 g of sodium hydroxide react with 22.0 g of hydrochloric acid to form 35.3g
disa [49]

Answer:

10.85 g of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

NaOH + HCl —> NaCl + H2O

Next, we shall determine the mass of NaOH that reacted and the mass of H2O produced from the balanced equation.

These can be obtained as illustrated below:

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

Mass of NaOH from the balanced equation = 1 × 40 = 40 g

Molar mass of H2O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mass of H2O from the balanced equation = 1 × 18 = 18 g

Summary:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Finally, we shall determine the mass of water, H2O produced from the reaction as follow:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Therefore, 24.1 g of NaOH will react to produce = (24.1 × 18)/40 = 10.85 g of H2O.

Therefore, 10.85 g of H2O were produced from the reaction.

kolbaska11 [484]

Answer:

C; Corrosive

Explanation:

Corrosive is related to the word “Corroded”

Ever heard of when batteries get corroded? That’s when they get old so the acid leaks and damages the actual battery. Same thing. So the answer is C.

I hope this helps! :D

Pls give thx and brainliest if I’m right ;)
