Answer:
Plant A
Explanation:
This is because Plant A is what you will compare to the other plants. Because it has no fertilizer is is the independent variable.
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
For simple equations, you can experiment with the balance of the number of atoms on the left and right
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄
aFe+bO₂⇒Fe₂O₃
Fe , left=a, right=2⇒a=2
O, left=2b, right=3⇒2b=3⇒b=3/2
the equation :
2Fe+3/2O₂⇒Fe₂O₃ x2
4Fe+3O₂⇒2Fe₂O₃
aCO₂+bCl₂⇒O₂+CCl₄
C, left=a, right=1⇒a=1
Cl, left=2b, right=4⇒b=2
O, left=2a, right=2⇒2a=2⇒a=1
the equation :
CO₂+2Cl₂⇒O₂+CCl₄
Answer:
2.39 atm
Explanation:
We'll begin by calculating the number of mole in 0.41 g of neon (Ne). This can be obtained as follow:
Mass of Ne = 0.41 g
Molar mass of Ne = 20 g/mol
Mole of Ne =.?
Mole = mass / molar mass
Mole of Ne = 0.41 / 20
Mole of Ne = 0.0205 mole
Next we shall convert 200 mL to L.
1000 mL = 1 L
Therefore,
200 mL = 200 mL × 1 L / 1000 mL
200 mL = 0.2 L
Next, we shall convert 11 °C to Kelvin temperature.
T(K) = T(°C) + 273
T(°C) = 11 °C
T(K) = 11 + 273
T (K) = 284 K
Finally, we shall determine the pressure. This can be obtained as follow:
Mole of Ne (n) = 0.0205 mole
Volume (V) = 0.2 L
Temperature (T) = 284 K
Gas constant (R) = 0.0821 atm.L/Kmol
Pressure (P) =?
PV = nRT
P × 0.2 = 0.0205 × 0.0821 × 284
P × 0.2 = 0.4779862
Divide both side by 0.2
P = 0.4779862 / 0.2
P = 2.49 atm
Therefore, the pressure of the gas is 2.39 atm
The formula SF_2 expresses one-third the amount of F.
The F:S ratio in the first compound is 6:1.
We want a compound with one third the amount of F, so F:S = 2:1.
The simplest formula with this ratio is SF_2.
I'm not positive what evaporations you need but I have these.....
1. Wind assists evaporation; for example in clothes dry faster under a fan.
2. Heat assists evaporation; for example, in summer clothes dry faster than in winter.
3. Increase in surface area exposed assists evaporation; for instance, a wet cloth spread out dries faster than when folded.
4. Dryness assists evaporation; for instance, clothes dry faster in summer than during the monsoon when the air is humid.
5. The rate of evaporation depends upon the nature of the liquid; for example, petrol evaporates faster than water.
6. Vapor pressure: if pressure is applied on the surface of a liquid, evaporation is hindered; consider, for example, the case of a pressure cooker.
