Pseudoscience refers to belief, theories and practices that claims to be scientific but which have no basis in scientific facts.
Pseudoscience has many traits two of which are:
1. It is based on dogma and uncritical belief. Counter evidence might draw hostility from pseudo scientists.
2. There is usually suppression or distortion of data. Pseudo scientists typically perform selective data gathering, in which they only gather and consider favorable data that support their claims. <span />
Answer:
23.2L
Explanation:
The following were obtained from the question:
V1 = 22.5L
P1 = 748 mmHg
P2 = 725mmHg
V2 =?
The new volume can be obtained by doing the following:
P1V1 = P2V2
22.5 x 748 = 725 x V2
Divide both side by 725
V2 = (22.4 x 748) /725
V2 = 23.2L
The new volume is 23.2L
Mass Percent of Hydrogen. To find the mass percent of hydrogen in water, take the molar mass of hydrogen in the water molecule, divide by the total molar mass of water, and multiply by 100. Dividing 2.016 by 18.016 gives you 0.1119. Multiply 0.1119 by 100 to get the answer: 11.19 percent
