Answer:
Adakah benar anda tidak boleh mencuci rambut, minum air sejuk dan
makan ais krim atau bersukan semasa haid? Terangkan jawapan anda.
Tidak, ini tidak benar, melakukan semua ini baik-baik saja. Seperti, tidak ada yang dapat mempengaruhi kita, kerana tidak bersambung dengan sistem kita. Juga, mohon maaf jika bahasa itu salah kerana saya menggunakan terjemahan Google.
Semoga ini membantu :)
Answer:
C
Explanation:
The definition of a triple point is where all of the phases are happening at once (weird, i know)
We can use the ideal gas law equation for the above reaction to find the number of moles present
PV = nRT
P - pressure - 1.41 atm x 101325 Pa/atm = 142 868 Pa
V - 109 x 10⁻⁶ m³
R - 8.314 Jmol⁻¹K⁻¹
T - 398 K
substituting the values in the equation
142 868 Pa x 109 x 10⁻⁶ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 398 K
n = 4.70 x 10⁻³ mol
number of moles = mass present / molar mass
molar mass = mass / number of moles
= 0.334 g/ 4.70 x 10⁻³ mol = 71.06 g/mol
halogens exist as diatomic molecules
Therefore atomic mass - 71.06 / 2 = 35.5
halogen with 35.5 g/mol is Cl
unknown halogen is Cl
Answer:
Volume also reduced to half
Explanation:
Volume and absolute temperature are directly proportional to each others
Answer:
Chemical fertilizers are compounds containing high concentration of nutrients required for plant growth. Apart from the three main constituent elements, carbon, oxygen and hydrogen, plants require substantial quantity of nutrients. These nutrients are classified as primary nutrients, secondary nutrients, and micronutrients. The elements responsible for providing these nutrients are listed in Table 7–1. Generally fertilizer industry is engaged in the production of primary plant nutrients suitable for application in the soil. In nitrogenous fertilizers, nitrogen is present as ammoniacal nitrogen such as ammonium sulphate, ammonium chloride; nitrate nitrogen such as calcium ammonium nitrate in which both ammoniacal and nitrate nitrogen are present, and amide nitrogen such as urea.
