Answer:
71.92 kPa
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (kPa)
P2 = final pressure (kPa)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
T1 = 50°C = 50 + 273 = 323K
V1 = 105L
T2 = -25°C = -25 + 273 = 248K
P2 = 105.4 kPa
P1 = ?
V2 = 55.0 L
Using P1V1/T1 = P2V2/T2
P1 × 105/323 = 105.4 × 55/248
105P1/323 = 5797/248
0.325P1 = 23.375
P1 = 23.375 ÷ 0.325
P1 = 71.92 kPa
Answer:
gold and platinum
Explanation:
Very unreactive metals, such as gold and platinum, are found in the Earth's crust as pure metals. These are called native metals.
Answer:
because of the dry season
Explanation:
the water evaporate from the ground which is taken by the sun for the process of rainfall
Egg yolk is the nutrient rich portion of the egg that caters to the nutritional needs of the growing embryo. Egg yolk is rich in many vitamins, minerals, phospholipids and proteins. Vitamins include the fat soluble ones-A, D, E and K. Minerals like phosphorus, calcium, iron and zinc are present abundantly in the yolk. Egg is also rich in the glycerophospholipid, lecithin. Cholesterol, a type of lipids is also abundant in the yolk.
So, the correct answer will be C) Lecithin
