Answer is 54 °C.
<em>Explanation;</em>
We can simply use heat equation
Q = mcΔT
Where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Let's assume that the initial temperature is T.
Q = 5.53 × 10⁵ J
m = 2850 g
c = 4.186 J/g °C
ΔT = (100 - T) °C <em>Since the water is boiling, the final temperature is 100 °C.</em>
By applying the equation,
5.53 × 10⁵ J = 2850 g x 4.186 J/g °C x (100 - T) °C
(100 - T) °C = 5.53 × 10⁵ J / (2850 g x 4.186 J/g °C )
(100 - T) °C = 46.35 °C
T = 100 - 46.35 C = 53.65 °C
≈ 54 °C
Answer:
0.031 parts per million
Explanation:
80 micrograms/m^3 = 80 micrograms/m^3 × 1m^3/1000L = 0.08 micrograms/L
Concentration in parts per million = concentration in micrograms/L × molar volume/MW
Concentration in micrograms/L = 0.08
Molar volume at 25°C and 101.325kPa (1 atm) is 24.45L
MW of SO2 = 64g/mole
Concentration in ppm = 0.08×24.45/64 = 0.031 ppm
Moles of copper nitrate:-
- 1mol of Copper nitrate reacts with 2mol NaOH
- 0.001mol will react with 0.002mol NaOH
Madd of NaOH
Nitrogen fixation is the process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria. The process is undertaken by the rhizobium bacteria that live in root roots of plants such as legumes. The mutualistic relationship is that the plant supplies the bacteria with a habitat in which to live, water, and nutrients, and the bacteria supply nitrogen for making plant proteins.
