Suppose that a fictitious element, X, has two isotopes: 59X (59.015 amu) and 62X (62.011 amu). The lighter isotope has an abundance of 57.7%. Calculate the atomic mass of the element X. Match the units to their metric weight:
The standard form of a quadratic equation is y = ax^2 + bx + c, where a, b, and c are coefficiencts and y and x are variables. It is easier to solve a quadratic equation when it is in standard form because you compute the solution with a, b, and c. However, if you need t...
Science is the pursuit of knowledge about the natural world. The discoveries made by scientists can be used to solve problems like diseases and access to energy. Science thus has the capacity to improve human quality of life. Answer and Explanation:1 ...
We encourage everyone touse less plasticandrecycleto solve the problems with plastic waste. Sources Lifecycle of Plastics (WWF)–https://wwf.org.au/blogs/the-lifecycle-of-plastics/
Of course, people remain worried about other kinds of emissions, such as intense radioactivity from long-lived waste isotopes. And older generation plants—that is, most of the ones operating today—are susceptible to core damage to varying degrees, with catastrophic results à la Chernobyl and Fu...
