Answer:
The solution is 0, 90 molal. See the explanation below, please
Explanation:
Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:
We calculate the weight of 1 mol of CaCl2
Weight Ca =40, 078 g
Weight Cl= 35, 453 g
Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g
110, 98 g ---1 mol
25 g---X= (25g x1 mol)/110, 98g= 0,23mol
250g solvent -----0,23 mol CaCl2 (the solute)
1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute
The solution is 0,90 molal
Answer:
1. Protein - build lean muscle and strengthen tendons
2. Lipids - insulation and long-term energy
3. Carbohydrates - provides quick, easily digested energy
4. Nucleic Acids - repair and replicate DNA and RNA
Explanation:
a. Think of protein as what helps your muscles grow and strengthen
b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)
c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.
d. nucleic acids - think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.
The answer is 3(x-2)(x+2)
The OCA2<span> gene's function is to provide inst</span><span>ructions in the process of making the p protein, hence the former name of the gene as P gene.An example of this process is the manufacturing in the body of melanin. The process of copying of OCA2 is called translation.</span>
