a) During a chemical reaction, atoms will always be combined into much larger
molecules.
b) Some of the atoms will always be changed into a different type of atom by a
chemical reaction.
c) Some of the atoms present before the reaction will always be lost during a
chemical reaction.
d) The same number of each type of atom will always be present before and after a
chemical reaction takes place.

Answers

d) The same number of each type of atom will always be present before and after a chemical reaction takes place.

Mass is never created or lost in a chemical reaction, so the atoms of each element must stay balanced.

A 20.0 mL of 0.27 M solution of the salt NaA has a pH of 8.70.

a) Calculate the pk, value of the acid HA.

(Correct to 3 sig. fig)

b) Calculate the pH of a solution containing 0.3 M HA and 0.1 M NaA.

(Correct to 3 sig. fig)

Answers

Answer:

a) 3.969

b) 3.489

Explanation:

a) Calculate the pk, value of the acid HA

PH of salt hydrolysis

P[tex]^{H}[/tex] = 1/2 ( pkw + pka + logC )

8.7 * 2 = 14 + log ( 0.27 ) + Pka

∴ Pka = 3.9686 ≈ 3.969

b) Calculate the PH of a solution containing 0.3 M HA and 0.1 M NaA

PH = Pka + log ( salt / acid )

= 3.9686 + log ( 0.1 / 0.3 )

= 3.9686 - 0.48 = 3.489

Two tons of water is pumped into a tank 15 ft. High in 5 minutes. Determine the power output of the pump. (Note: One ton is equal to 2,000 lb. And remember to convert the minutes to seconds.)

Answers

Answer:

200 lb•ft/s

Explanation:

From the question given above, the following data were obtained:

Force (F) = 2 tons

Time (t) = 5 mins

Height (h) = 15 ft

Power (P) =?

Next, we shall convert 2 tons to pound. This can be obtained as follow:

1 ton = 2000 lb

Therefore,

2 tons = 2 × 2000

2 tons = 4000 lb

Next, we shall convert 5 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

5 mins = 5 × 60

5 mins = 300 s

Finally, we shall determine the power of the pump. This can be obtained as follow:

Force (F) = 4000 lb

Time (t) = 300 s

Height (h) = 15 ft

Power (P) =?

P = F × h / t

P = 4000 × 15 / 300

P = 60000 / 300

P = 200 lb•ft/s

Thus, the power of the pump is 200 lb•ft/s

Answer:

It's 200 ft-lb/sec

Which property of sulphuric acid makes it suitable to use as a catalyst for the preparation of esters?

Answers

In Fisher esterification, sulfuric acid is used as a catalyst and its function is to convert the carboxylic compound in its conjugate acid. This favours the nucleophilic attack of the alcohol. To act as a catalyst you need a strong acid, therefore sulphuric acid is suitable for this kind of reaction.

Specific Heat Formula: q = mcΔT

q is heat (in Joules)m is mass (in grams)c is specific heat (in J/g °C)ΔT is change in temperatureExplanation:

Step 1: Define

[Given] m = 38.8 g

[Given] q = 181 J

[Given] ΔT = 36.0 °C - 25.0 °C = 11.0 °C

[Solve] c

Step 2: Solve for Specific Heat

Substitute in variables [Specific Heat Formula]: 181 J = (38.8 g)c(11.0 °C)Multiply: 181 J = (426.8 g °C)c[Division Property of Equality] Isolate c: 0.424086 J/g °C = cRewrite: c = 0.424086 J/g °C

Question 7 (1 point
What is the general pattern seen in the periodic table that helps a person quickly identify if an element is a nonmetal? (Where are nonmetals
generally found on the periodic table?)

Answers

Answer:

the elements to the right including hydrogen

Explanation:

as you know non-metal tend to gain eletrons

basically group 5, 6, and 7 are nonmetals

group 1, 2, and 3 are metals and group 4 are transitional metals so be careful with group 4

Well, the simple is that metals will be located on the left side of the periodic table and non metals will be located on the right side. But, what you can do is whatever elements is located on the LEFT side of the STAIRCASE (where the metalloids are) are considered METALS and the elements to the RIGHT of the staircase are NONMETALS and the elements that are touching the staircase are metalloids. Also Hydrogen is a NONMETAL, yes it’s located to the left BUT it’s a no metals because it has the properties/requirements of a nonmetal. Another element I’ll like to mention is Aluminum. Aluminum is touching the staircase BUT it is not a metalloid. It is a metal.

A sample of hydrogen changes its pressure from 756 torr to 499 torr while the temperature remains constant. After the pressure is reduced, the volume of the gas is 789 mL. What was the original volume?

Answers

P1 = 756 torr

P2 = 499 torr

V2 = 789 mL

V1 = ?

applying Boyle's Law

P1 * V1 = P2 * V2

756 torr * V1 = 499 torr * 789 mL

V1 = 499 torr * 789 mL / 756 torr

V1 = 520.78 mL
