laila [671]

Answer:

mass water = 32.4 g

Explanation:

specific heat iron = 0.450 J/g°C

specific heat water = 4.18 J/g°C

32.8 x 0.450 ( 59.1 - 22.4) + mass water x 4.18 ( 59.1- 63.1)=0

541.7 - mass water x 16.7 = 0

mass water = 32.4 g

It Is A Type Of Lily

Regarded botanically as perennial with the scientific name herbaceous perennial, Agapanthus Peter Pan is an African lily. Hence, it’s also called as “The Blue African Lily of the Nile”. The flowers appear in trumpet-shaped rounded clusters with darker mid-vein petals.

They come out in an upright position due to its long stalks and are surrounded by narrow, loose and strap-shaped leaves. In addition, some categorize the plant under bulbs although it’s not, but due to the fact that it has fleshy and thick roots.

#3 – It Has Other Names

There are other terms known for Agapanthus Peter Pan. Other than simply African lily, this is often called as The Blue African Lily of the Nile, African Lily Peter Pan, Lily of the Nile Peter Pan, Dwarf Lily of the Nile and Dwarf African Lily.  This also explains the reason why most of the imported evergreen agapanthus came from certain parts of South Africa as these are better grown in milder climate areas with higher or heavy rainfall.

Therefore, the flowers typically bloom from the months of July to August, which are commonly known as the summer season in the US, Canada and Europe, and extends up to October. Of course, you’d see the glamorous, blue flowers in spring too.

#5 – It Needs Full Sun

This beautiful flower relies on sunlight in order to grow and remain healthy. However, planting it around a partly shaded area is alright.

You also have to keep in mind that this kind of plant must not be dried out or else it dies. Thus, watering regularly is a basic priority.

#6 – It Can Survive The Winter

Although it’s best planted in milder areas and sunny season, Agapanthus Peter Pan can endure the coldness of fall and winter seasons. In fact, you can place foliage in a pot or a small container so you can easily transport it inside your home.

This also implies that you don’t need a large, spacious garden to display this plant around your surroundings.

#7 – It Is Not Shrubby

Unlike some plants, Agapanthus Peter Pan grow in almost round, V-shape without spreading in a way that it reaches to an unparalleled position.

Its spread extends from 1 to 2 inches. Nevertheless, it can definitely create an elegant landscape view whether it’s planted in front of your house or in the backyard.

Based on an article excerpt from Plant Care Today, Agapanthus plants generally grow from 18 inches to 5 feet depending on the variant. But for Agapanthus Peter Pan, it can grow to a minimum height of 8 inches to 18 inches.

#8 – It Most Likely Grows In Moist, Drained Soil

In addition to the climate, remember that plants are best nurtured in an area where the kind of soil is met. It has to be a soil type of chalk, clay, loam or sand. In the case of Agapanthus Peter Pan, fertile, moist and well-drained soil must be considered.

#9 – It Is Easy To Grow

This plant requires low maintenance. All you need is enough sun, water and well-drained soil. Consider adding some organic material for fertilizing if you want to keep the plant healthy and flowers stunningly beautiful.

#10 – It Attracts Butterflies And Birds

The beauty of the blue flowers of Agapanthus Peter Pan is evident and undeniable due to the fact that they are favorite places for small birds and butterflies to go to. An even more so interesting fact is that it’s free from pests and diseases. It is also rabbit, deer and drought resistant.

Growing and Maintenance Tips:

As mentioned previously, Agapanthus Peter Pan is less difficult to take care of. But doing the right way is still vital to bear in mind. So here’s a list of quick tips on how to properly plant this agapanthus for beginners and maintain its beautiful foliage.

The Planting Process

1. If you choose to plant in the ground, dig holes but not too deep.

2. Amend the soil with some organic matter as fertilizer.

3. Carefully remove the plants from the containers and make sure the root ball is intact.

4. Loosen the soil and roots around the bottom as well as the edges of the root ball.

5. Place the plant in the hole leveling with surrounding soil, and spread roots outward.

6. Fill in the hole and around the roots with amended native soil.

7. Gently water.

8. Cover the whole area with leaf or bark.

9. Water again but this time deeply.

The Regular Watering Process

Water every morning. Night watering may promote diseases. As you water, go slowly and deeply, and if possible, do it twice with a few minutes apart. Keep in mind that you avoid over watering as this can cause some root problems. To conserve water, use a hose.  Just keep the soil wet! And water the flowers everyday!

If a solution of hf (ka = 6.8 10-4) has a ph of 3.67, calculate the total concentration of hydrofluoric acid.
m_a_m_a [10]
When PH = ㏒(H^+)
[H+] = 10^-3.67
[H+] = 2.14x 10^-4

so according to the reaction equation:
                               HF               ↔        H^+          +          F^-
at equilibrium   X-(2.14x10^-4)           (2.14x10^-4)         (2.14x10^-4)

by substitution in Ka formula:
       Ka      = [H+][F]-/[HF]
6.8x10^-4 = (2.14x10^-4)*(2.14x10^-4) /(X-2.4x10^-4)
X-2.4x10^-4 = (4.58x10^-8)* (6.8x10^-4)
∴X = 2.4x10^-4
∴[HF] = X- (2.14x10^-4)= (2.4x10^-4)-(2.14x10^-4) = 2.6 X 10^-5
