Answer:
Explanation:
magnesium + nitrogen ⟶ Product
13 g 5 g
Mass of product = 13 g + 5 g = 18 g
The product contains 5 g of nitrogen
.
Answer: 207.24
Explanation: Atomic mass = no of protons + no of neutrons
1) 82 protons, 122 neutrons , mass number= 82+122 = 204
2) 82 protons, 125 neutrons, mass number= 82+125 = 207
3) 82 protons, 124 neutrons, mass number= 82+124 = 206
4) 82 protons, 126 neutrons, mass number= 82+126 = 208
Average atomic mass of an element =
Average atomic mass of given element =
The approximate atomic mass of lead is 207.24.
Answer:
We can no longer ignore the fact that the world's climate is becoming more unpredictable and more extreme. As water levels rise, the risk of flooding looms large. At the same time, periods of drought are becoming longer and more frequent. Yet, our most precious resource – our planet's biosphere – is not only under threat. It is also the source of many of our solutions. Green Climate Solutions is the Wageningen Environmental Research programme that applies our understanding of nature and natural processes to address the challenges of climate change.
