4. sifat kimia CaSO4.2HzO apa? simbol bahaya dari natrium thiosulfat, calsium karbonat, calsium slfate,phenolphalein, calcium cloride, magnesium sulfate, natrium acetat, sodium cloride, ammonia sulfat ?
Sifat kimia CaSO4 (gipsum) adalah basa, korosif. Gipsum termasuk mineral dengan sistem kristal monoklin 2/m, namun kristal gipsnyamasuk ke dalam sistem kristal orthorombik. Gipsum umumnya berwarna putih, kelabu,cokelat, kuning, dan transparan. Hal ini tergantung mineral lain yang bercampur dengangipsum.Gipsum umumnya memiliki sifat lunak. Gipsum memiliki kilap sutra hingga kilap lilin, tergantung dari jenisnya. Genesa :Gypsum merupakan mineral sedimen kimiawi (evaporit) yg khas, terbentuk melalui pengendapan langsung dr air garam/ merupakan hasil hidrasi/alterasi anhidrit selama prosesdiagenesa. Gipsum dpt juga terbtk oleh sublimasi langsung dr fumarola/diendapkan mata air panas. Juga diagenesa sebagai Galian block-block konkresi dlm lempung dan napal, sedanganhidrit merupakan hasil dehidrasi gypsum. Sifat Optik. Pada sayatan tipis, gypsum tidak berwarna.
berwarna putih, memiliki derajat ketransparanan dari jenis transparan hingga translucent,serta memiliki sifat menolak magnet atau disebut diamagnetit.

10. How many grams of calcium chloride, CaCl, should be used to prepare 250.00 mL solution with a concentration of 0.500 M.
Penjelasan:
rumus :
M = n/V atau Massa / Mr × 1000 mL / mL
n = Mr/M × 1000 / mL
massa = Mr × M × V
Jawab :
massa = 0,5 M . 75,5 g/mol . 0,25 L
massa = 9,4375 gram
11. which has more neutrons, potassium, or calcium
Jawaban:

14. when 1.11 gram calcium chloride dissolved in water, the freeze point of the solution is 0,11165•C. if the calcium chloride iss completely dissosiated and Kf water = 1,86 •C/m , then the total mass of the water in the solution is...... gram (relative atomic mass: Ca=40, Cl=35,5)
CaCl2 merupakan elektrolit kuat maka i = n = 3
ΔTf = (gr ÷ Mr) × (1000 ÷ p) × Kf × i
0,11165 = (1,11 ÷ 111) × (1000 ÷ p) × 1,86 × 3
p = 499,77 ≈ 500 mL
15. Which atom loses two electron from its outer shell to form an ion? A Calcium B Carbon C Chloride D Oxygen
A calcium
Because calcium need to give 2 electron to make the calcium stable
16. 1. Which of the following elements is not taken up from the soil?A. PotassiumB. MagnesiumC. CarbonD. CalciumE. Sulfur

17. If 149.5 g of potassium chloride is dissolved in water to make 500 ml solution, what is the molarity and in g/dm3 of the solution?
Jawaban:
[tex]=\frac{149.5}{74.55}x\frac{1000}{500} \\=4.01 molar[/tex]

18. Calculate the number of moles of the indicated substance present in each of the following samples. a) 1.95 x 10-3 g of lithium carbonate. b) 4.23 kg of calcium chloride. c) 1.23 mg of strontium chloride.
The number of moles of the indicated substance present in each of the samples is as follows.
1.95 x 10-3 g of lithium carbonate = 2.64 x 10⁻⁵ moles4.23 kg of calcium chloride = 28.01 moles1.23 mg of strontium chloride = 7.74 x 10⁻⁶ moles(in two decimal places)
Penjelasan:
Data of relative atomic mass
Ar Li = 7Ar C = 12Ar O = 16Ar Ca = 40Ar Cl = 35.5Ar Sr = 88Data of relative molecular mass
Mr of lithium carbonate Li₂CO₃ = 2(7) + 12 + 3(16) = 74Mr of calcium chloride CaCl₂ = 2(40) + 2(35.5) = 151Mr of strontium chloride SrCl₂ = 88 + 2(35.5) = 159The formula: [tex]\boxed{moles~n = \frac{mass~(grams)}{Mr~(g.mol^{-1})} }[/tex]
Calculation
[tex]\boxed{n = \frac{1.95 \times 10^{-3} \, g}{74 \, g.mol^{-1}} = 2.64\times 10^{-5} \,moles\, of \, lithium \, carbonate }[/tex]
[tex]\boxed{n = \frac{4.23 \times 10^{3} \, g}{151 \, g.mol^{-1}} = 28.01 \,moles\, of \, calcium\, chloride }[/tex]
[tex]\boxed{n = \frac{1.23 \times 10^{-3} \, g}{159 \, g.mol^{-1}} = 7.74 \times 10^{-6} \,moles\, of \, strontium \, chloride }[/tex]
