Answer: (P2/P1)=(T2/T1)
(P2/1200.0kPa)=(387/283)
P2=(387K/283K) * (1200kPa)
P2= 1641kPa
Explanation:
Answer:
5.0 %
Explanation:
Given data
- Volume of ethylene glycol (solute): 50 mL
- Volume of water (solvent): 950 mL
Step 1: Calculate the volume of solution
If we assume that <em>the volumes are additive</em>, the volume of the solution is equal to the sum of the volume of the solute and the solvent.
V = 50 mL + 950 mL = 1000 mL
Step 2: Calculate the percent by volume
We will use the following expression.
The correct answer is because sanitary pads and diapers are in direct contact with external genitalia for an extended period of time, a significant amount of VOCs or phthalates may be absorbed into the reproductive system.
Sanitary pads and diapers are made of synthetic plastic materials that can leach into the environment when used. The amounts of volatile organic compounds (VOCs) (methylene chloride, toluene, and xylene) and phthalates (DBP, DEHP, DEP, and BBP) found in sanitary pads and diapers were measured in this study. VOC and phthalate concentrations in sanitary pads varied by 5,900 and 130 times, respectively. VOC and phthalate concentrations in diapers varied by three and sixty-three times between brands. The VOC concentrations in sanitary pads and diapers were comparable to those in residential air. However, sanitary pads and diapers had significantly higher phthalate concentrations than common commercial plastic products.

Answer:
23 protons, 23 electrons, 33 neutrons
Explanation:
I don't know why my answer got deleted but no worries, I can answer again. The number of protons and electrons is equal to the atomic number which is 23 and the number of neutrons is 56 - 23 = 33 because atomic mass denotes the number of protons and neutrons.
Answer:
It would take 15 sticks of butter
Explanation:
2 divided by 20 is 0.1
0.1 is how much butter for 1 so now we multiply that by 150
0.1 x 150 = 15
Therefore, you would need 15 sticks of butter for 150 cookies
