Answer. One of the key components of the softgel capsule is the plasticizer used to make the shell elastic and pliable and to minimize brittleness and cracking. The plasticizer usually accounts for 20-30% of the wet gel formulation which can impact the quality of the finished product.
Explanation:
Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, theexhaust<span> from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.</span>
The answer is D. Wind
Wind is considered physical weathering
Answer:
A. is not
B. incorrect
C. identify substances that have the measured molecular mass
Explanation:
Since in the question it is mentioned that the Christy who is a forensic scientist and she gave a white powder and identify whether it is a sugar or not when she tested she seen that the molecular mass is different as compared with the sugar
So here it can be concluded that the white powder does not show a sugar that means it is not a sugar so automatically the hypothesis of Christy is wrong. And, the next step is to track the substance that shows the molecular mass i.e. measured
Remember that:
number of moles = mass/molar mass
First, we get the molar mass of the nitrogen gas molecule:
It is known the the nitrogen gas is composed of two nitrogen atoms, each with molar mass 14 gm (from the periodic table)
Therefore, molar mass of nitrogen gas = 14 x 2 = 28 gm
Second we calculate the mass of the precipitate:
we have number of moles = 0.03 moles (given)
and molar mass = 28 gm (calculated)
Using the equation mentioned before,
mass = number of moles x molar mass = 0.03 x 28 = 0.84 gm
