Answer:
Four times the original amount if only one orange was used
Explanation:
We can assume that the oranges all have equal voltages. Connecting them in series will have an increasing effect on the voltage delivered. In our case, this will produce 4 times the voltage of the circuit when only one orange is used.
Whenever simple cells are connected in series, the voltages of the individual cells are added up to form the voltage of the whole circuit.
Let us assume that the voltage of each of the oranges is approximately 0.9 volts. The Voltage produced when the 4 oranges are joined in series is 0.9 + 0.9 + 0.9 + 0.9 = 3.6 volts
Answer:
%Ionization = 1.63%
Explanation:
Hydrazine in aqueous media theoretically forms a difunctional hydroxyl system. However, for this problem assume only monofunctional ionization occurs. A second hydroxyl ionization would not likely occur as the formal cationic charge formed in the 1st ionization would inhibit a second ionization.
H₂NNH₂ + 2H₂O => HONHNHOH => HONHNH⁺ + OH⁻; Kb = 1.3 x 10⁻⁶
So, assuming all OH⁻ and HONHNH⁺ are delivered in the 1st ionization then a good estimate of the %ionization can be calculated.
HONHNHOH => HONHNH⁺ + OH⁻
C(i) => 0.490M 0M 0M
ΔC => -x +x +x
C(eq) => 0.490 - x x x
≅0.490M* => *x is dropped as Conc H₂NNH₂/Kb > 100
Kb = [HONHNH⁺][OH⁻]/[HONHNHOH]
1.3 x 10⁻⁶ = x²/0.490
=> x = [OH⁻] = [HONHNH⁺] = √[(1.3 x 10⁻⁶)(0.490)] = 8 x 10⁻⁴
=> %Ionization = (x/0.490)100% = (8 x 10⁻⁴/0.490)100% = 1.63%
The reacting equation of the reaction is as follows
AgBr (S) + 2 Na2S2O3 ----> Na3Ag(S2O3) + NaBr
the moles of Na2S203= 0.350 x 1l= 0.350moles
by use of reacting ratio AgBr to Na2S2O3 which is 1:2
therefore the moles of AgBr = 0.350/2=0.175moles
mass is hence= moles x molar mass of AgBr
0.175 x187.8=32.865g
Explanation:
1. carbon cycle
all of the physical processes and chemical reactions that result in the movement of carbon between the biosphere (living forms) and the geosphere (water, earth, and atmosphere)
Carbon cycle is the cyclic movement of carbon in various form on earth. This process entails both physical and chemical processes that ensures that carbon moves in different spheres of the earth. Carbon is one of the most important element in life. It is the building block of most organic processes on earth.
2. carbon footprint
a calculation that considers an individual's contribution to the process of global warming based on activities leading to greenhouse gas production
Carbon footprint is important in mapping the quota of carbon emitted into the atmosphere
It is the amount of greenhouse gases contributed into the atmosphere by individuals.
3. global warming
an overall increase in world temperatures that may be caused by additional heat being trapped by greenhouse gases
It is the overall increase in global temperature. It has severe consequences.
Global warming results when greenhouse gases in the atmosphere traps outgoing radiation in an anomalous way.
4. greenhouse gas
components of the air mixture that trap infrared (heat) energy
Greenhouse gases are gases that prevents long wave radiation from leaving the earth surface. They absorb the gases in turn, warming occurs on earth.

Answer - 1.50 M Na
Explanation -
3.00 moles of Na over 2.00 L of water.
3.00/2.00 = 1.50 M Na
I cannot be entirely sure. But it's an educated guess.
