Answer:
renewable resource
Explanation:
The sustainable yield of a resource is the highest rate at which we can use a renewable resource without reducing its available supply.
- The amount of resources that can be harnessed without any effect on resource falls into this category.
- In exploiting renewable resources balance between the available resource and usage must be attained.
- This helps to conserve such limited resource.
The answer
the general equation of the reaction is
<span>NH4NO3 -------------- N2O + 2H2O
</span><span>The molar mass of NH4NO3 is 80.03
</span>The mass of NH4NO3 is <span>160.1 g
so we can deduce that
n</span>NH4NO3 = number of mole of NH4NO3 = 160.1 g / 80.03 =2 moles
by using proportion property
NH4NO3 -------------- N2O + 2H2O
1mole 1mole 2 moles
nNH4NO3 nH2O
the number of mole nH2O can be found by
1/ nNH4NO3 = 2 / nH2O
nH2O = 2 x nNH4NO3 = 2 x 2 = 4 moles
to find the mass, we use
mH2O = 4 moles x 18.01 g /mol = 36 g
Answer:
B-29
Explanation:
Since there are 29 positive charges in the nucleus, there must be 29 negative charges. And cause the atomic number of copper is 29.
Answer:
<h2>20 kg</h2>
