The 1st one. Fertilizers are like food for plants, and that's what an algae is, sorta. Trout's don't eat algae and if there's too much algae around, it gets dirty and they eventually die because of the amount of bacteria in the algae. It's the same thing if you have a fish tank.
Answer:
Explanation:
use this fromula
q = m c ∆t
m is mass of silver =50 g
∆t is difference in temperature= 255-106=149
C= specific heat fo silver ( should be mentioned in your question )
Mg(NO3)2 ➡️ Mg2+ + 2 NO3-
（32.0g Mg(NO3)2) / (148.3g Mg(NO3)2/mol)* (2 mol NO3- / 1 mol Mg(NO3)2) / (0.425 L) = 1.02 mol/ L NO3-
Answer:
- Scientific question: does life exist on other planets?
- Non-scientific question: there are aliens that look like people?
Explanation:
A scientific question is a coherent question that can be used to develop a scientific hypothesis. Thus, a scientific question must be testable, verifiable, measurable and relevant to the topic of study. In the scientific method, the hypothesis is subsequently tested by experimental or observational procedures, where the results can be used to understand some particular aspect of the real world. On the other hand, a non-scientific question is a light conjecture which cannot be proved by using the scientific method.
