Answer:
Here's what I get.
Explanation:
Your unbalanced nuclear equation is:
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
95 = x + 2, so x = 95 - 2 = 93
243 = y + 4, so y = 243 - 4 = 239
Element 93 is neptunium, so the nuclear equation becomes
Assuming the plumbing pipe is PVC, the answer would be nonmetal
PVC or polyvinyl chloride has a chemical formula of (C2H3Cl)n. From the element, we can see that the polyvinyl chloride is made from carbon, hydrogen, and chloride. There are no elements that belong to the metal group or metalloid group, so the plumbing pipe would be nonmetal.
No volcanoes are formed by tectonic plates down below the ground
Answer:
B. Greenhouse gases are released into the atmosphere.
I learn it in my bio class
In exothermic reactions, there is a release heat and the replacement of weak bonds with stronger ones.
