2. does the temperature of water affect the solubility of salt?
Apakah suhu air mempengaruhikelarutan garam?
Iya, karena di dalam larutan garam, garam dikatakan sebagai zat terlarut (solute) dan air sebagai zat pelarut (solvent). Jumlah garam maksimal yang dapat larut dalam 100 gram air pada suhu 25°C adalah 36 gram. Dengan demikian dapat dikatakan bahwa kelarutan garam dalam air yang bersuhu 25°C adalah 36 gram/100 gram air. Jadi kelarutan menyatakan jumlah maksimum zat terlarut yang dapat melarut dalam sejumlah zat pelarut pada suhu tertentu.
Does the temperature of water affect the solubility of salt?
Yes, because in a salt solution, salt is said to be a solute (solute) and water as a solvent (solvent). The maximum amount of salt that can dissolve in 100 grams of water at 25° C is 36 grams. Thus it can be said that the salt solubility in water at 25° C is 36 grams/100 grams of water. So solubility expresses the maximum amount of solute that can dissolve in a certain amount of solvent at a certain temperature.

It means…. a. their body temperature changes when the outside temperature changes. b. they can maintain a constant body temperature regardless of the temperature of the surroundings. c. they are able to regulate their internal temperature. d. they can maintain a constant body temperature.
Jawaban:
A.
Penjelasan:
Hewan berdarah dingin tidak mempertahankan suhu tubuh yang konstan. Mereka mendapatkan panas dari lingkungan luar, sehingga suhu tubuh mereka berfluktuasi, berdasarkan suhu eksternal. Jika suhu di luar 50 °F, suhu tubuh mereka pada akhirnya akan turun menjadi 50 °F juga.

9. Diagram 5 shows the graph of a quadratic function y = f(x)
a. y = 21+4x-x²
0 = 21+4x-x²
0 = (7-x)(3+x)
x = 7 atau x = -3
b. mencari sumbu simetri di turunan pertama:
y = 21+4x-x²
y' = 4 - 2x ; subtitusi y' = 0 (karena pada titik puncak, m=0)
0 = 4 - 2x
2x = 4
x = 2 ← sumbu simetri
10. explain how you would find the solubility of a solute
Jawaban:
Information :
S = solubility
n = moles of solute
gr = mass of solute (grams)
Mr = relative molecular mass
V = volume of solution (L)

13. explain how the liquid in a thermometer changes so that it can be used to measure a temperature.pls help me!!!
As the temperature around the thermometer's bulb heats up, the liquid rises in the glass tube. The glass tube is mounted on a backboard that is marked in units called degrees. When it is hot, the liquid inside the thermometer will expand and rise in the tube. The opposite happens when it is cold.
14. What is y- intercept point of the graph below?
Jawaban:
(0,-6)
Penjelasan dengan langkah-langkah:
ingat bahwa y- intercept point (titik potong sumbu y) adalah titik yang memotong sumbu y (vertikal) dan titik bertemunya garis di x=0
lokasinya pada fungsi kuadrat adalah (0,c)
misal...
x² - 2x + 3
a = 1
b = -2
c=3
maka titik potong sumbu y adalah (0, 3)
--------
di grafik, titik potong sumbu y berada di (0,-6)

19. The temperature of a substance measured by a Reaumur thermometer is 40°R. When measured with a Celsius thermometer, it shows the temperature is
Answer:
50°C
Explanation:
Based on the formula, we can get the formula to convert Reaumur to Celsius.
°C = [tex]\frac{5}{4}[/tex] °R
So, let's go back to the problem. Then, substitute the number to the formula.
40°R = ... °C
40°R = [tex]\frac{5}{4}[/tex] × 40
40°R = 50°C
So, we can get get that 40°R as same as 50°C.
20. the bar graph shows the number of fruits sold by a stall in one afternoon
A) the average number of fruits sold is the sum of the fruits sold divided by the number of fruits. (360/4) = 90.
B) Orange = 0.40 x 120 = $48
Pear = 0.65 x 95 = $61.75
Banana = 1 x 60 = $60
Papaya = 2.50 x 85 = $212.5
Totalamountofmoney:48+61.75+60+212.5=$382.25
Hopeithelps.
