How does engineering affect the amount of human labor needed to harvest rice?
Answer:
Yes
Explanation:
The first step of harvesting is draining the paddy. Next, farmers cut the plants -- with a scythe or sickle if by hand -- and transport them elsewhere to be laid out and dried for two or three days. Rice can be cut by hand or machine. In the developed world, harvesting by hand is still very common.

N2 + 3H2 → 2NH3
Using the volume ratio, determine how many liters of NH3 is
produced if 1.2 liters of H₂ reacts with an excess of N2, if all
measurements are taken at the same temperature and
pressure? (5 points)
Answer: 0.8 liters
Explanation:
Given chemical reaction is:
N₂ + 3H₂ → 2NH₃
From the stoichiometry of the reaction, it is clear that:
3 liters of H₂ = produce 2 liters of NH₃
1.2 liters of H₂ = produce 2/3 × 1.2 = 0.8 liters of NH₃
(If it says 0.80, that's the same as 0.8!)
Answer: 0.8 liters
Explanation: Given chemical reaction is:N₂ + 3H₂ → 2NH₃From the stoichiometry of the reaction, it is clear that:3 liters of H₂ = produce 2 liters of NH₃1.2 liters of H₂ = produce 2/3 × 1.2 = 0.8 liters of NH₃(If it says 0.80, that's the same as 0.8!)

How many moles of C are in a sample of C5H12 that also contains 22.5g of H?
The number of moles of C present in C₅H₁₂ that contains 22.5 g of H is 9.375 moles
How to determine the mass of C₅H₁₂ that contains 22.5 g of H
1 mole of C₅H₁₂ = (12×5) + (1×12) = 72 g
Mass of H in 1 mole of C₅H₁₂ = 12 × 1 = 12 g
Thus,
12 g of H is present in 72 g of C₅H₁₂
Therefore,
22.5 g of H will be present in = (22.5 × 72) / 12 = 135 g of C₅H₁₂
How to determine the mole of C present in 135 g of C₅H₁₂72 g of C₅H₁₂ contains 5 moles of C
Therefore,
135 g of C₅H₁₂ will contain = (135 × 5) / 72 = 9.375 moles of C
Thus, 9.375 moles of C is present in C₅H₁₂ that contains 22.5 g of H

What volume of nitrogen reacts with 33.6 litres of oxygen to produce nitrogen dioxide?
1 mol of every gas weighs 22.4L at STP

0.5 mol N_2 required for 1 mol O_2
Moles of Nitrogen
0.5(1.5)0.75molVolume
22.4(0.75)16.8LConsider the reaction is taking place at standard temperature and pressure. Then 22.4 L reacts with 44.8 L of oxygen. Thus, 33.6 L of oxygen needs 16.8 L of nitrogen.
What is STP condition?The condition of STP is the standard temperature and pressure. The temperature of 298 K and pressure of 1 atm is called the standard condition.
At STP the volume of every substance is 22.4 L. The reaction of nitrogen and oxygen forming nitrogen dioxide is given below:
[tex]\rm N_{2} + 2O _{2} \rightarrow 2 NO_{2}[/tex]
As per this reaction, 22.4 L of nitrogen reacts with (2 × 22.4) = 44.8 L of oxygen. Hence, the volume of nitrogen required by 33.6 L of oxygen is calculated as follows:
(33.6 L × 22.4 L) / 44.8 L = 16.8 L
Therefore, the volume of nitrogen required to react with 33.6 L of oxygen is 16.8 L.

What is the heat abosorbed by 47.5g of silver (Ag) when the temperature rises by 10.0C?
The heat absorbed by 47.5g of silver (Ag) when the temperature rises by 10 °C is 111.625 J .
What is Specific Heat ?Specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree.
The units of specific heat are usually calories or joules per gram per Celsius degree.
The equation used to solve for specific heat capacity is this:
q = mcΔT
where q heat absorbed or lost,
c is the specific heat capacity,
m is the mass, and
ΔT is the change in temperature
= final temperature− initial temperature
Given that m = 47.5g
ΔT = 10 K
Specific Heat of silver = 0.235 J/gK
Therefore
q = 47.5 * 0.235 * 10
q= 111.625 J
