Acid and Base Identification

Aliun [14]

1.A (when acids react with organic molecules on your skin the reaction is highly exothermic which is why it burns you)
2.C (acids and bases can dissociate into ions or create ions)
3. B (bases tend to taste bitter an example being soap)
4.A (acids tend to taste sour an example being citric acid from lemons)
5. A (the arrhenius acid definition is that acids dissociates into H⁺ ions)
6. B (the arrhenius base definition is that bases dissociate into OH⁻ ions)
7. C (Strong acid-strong base or weak acid-strong base reactions form water and salts)
8. A (I have heard that some metals can be corroded by some bases but I don't think bases usually corrode metal)
9. A (acids have lower pH values with 7 being neutral)
10. B (bases have higher pH values with 7 being neutral)
11. A (these are some of the strong acids)
12. B (these are some of the strong bases)

I hope this helps. Let me know if anything is unclear.

Need help solving these questions

Anton [14]

Answer:

1) 100

2) 22

3) 39

4) 6

5) 2b + 6

6) 8

7) 4n + 20

Explanation:

If B is the midpoint of AC and C is the midpoint of BD, means that all 3 parts are equal. AB = BC = CD

1) If AB = 50 then AC = AB + BC = 50 +50 = 100

2)if BD = 44 then is CD = 44 - BC ⇔ CD = 44 - 22 = 22

3) if AC = 26 and AC = AB + BC then each part is 13

AD = AC + CD = 26 +13 = 39

4)if CD = 6 then AB = 6 Because all single parts are equal

5) if AC = 4b + 12 then is AB the half of it = 2b +6

6) if AD = 24 then AB = 1/3 of it = 8

7)if BC is 2n + 10 then is AC = 2x BC = 4n + 20

How much heat is needed to change the temperature of a 30.0 gram sample of copper from 20.0c to 60.0c?

guajiro [1.7K]

Answer: 462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.

Explanation:

Mass of copper,m = 30.0 grams

Specific heat capacity of copper,c = $0.385 J/g ^oC$

$T_1=20^oC,T_2=60^oC$

$\Delta T=T_2-T_1=60^oC-20^oC=40^oC$

$Q=mc\Delta T$

$Q=30.0 grams\times 0.385 J/g ^oC\times 40^oC=462.00 J$

462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.

You leave for school late when you are pulled over by a police officer for speeding. He clocks you at 52 mi/hr . What is your sp

yawa3891 [41]

Answer:

Explanation:

The maximum speed limit in Prince Edward Island

unless otherwise posted is 80 kilometres per hour

(km/h). The basic speed limits are:

• 40 km/h (25 mph) in most municipalities

(municipalities may establish the maximum

speed limit within their boundaries);

• 50 km/h (30 mph) in urban areas;

• 60 km/h (40 mph) in school zones designated as

such by the erection of signs at the entrance and

the exit, between 8 a.m. and 5 p.m. when

children are present on or near the highway on

school days;

• 80 km/h (50 mph) on most provincial highways;

and

• 90 km/h (55 mph) on the TransCanada and

other designated highways.

Posted speed limits indicate the maximum safe

speed under favourable driving conditions.
