Answer:
C. decrease
Explanation:
Price increases on goods in the economy signal producers to decrease production.
Producers benefits more when the price of goods and services increases in the market. This makes them have more profit.
To maintain this profit level, they often decrease their production output to create a form of artificial scarcity within the market to sustain the price at which their goods trades.
If the producer increases the amount of goods they produce, this flux of goods can cause a decrease in price as the consumer is favored with a good bargaining power.Answer:

What mass of nitrogen monoxide is formed in the reaction of 869kg ammonia and 2480kg oxygen gas? (Please show work)
Answer:
1533.6 kg NO
Explanation:
The reaction that takes place is:
4NH₃ + 5O₂ → 4NO + 6H₂OFirst we convert the masses of ammonia (NH₃) and oxygen gas (O₂) into moles, using their respective molar masses:
NH₃ ⇒ 869 kg ÷ 17 kg/kmol = 51.12 kmol NH₃O₂ ⇒ 2480 kg ÷ 32 kg/kmol = 77.5 kmol O₂77.5 kmol of O₂ would react completely with (77.5 kmol O₂ * [tex]\frac{4kmolNH_3}{5kmolO_2}[/tex]) 62 kmol of NH₃. There are not as many kmol of NH₃, so NH₃ is the limiting reactant.
Now we calculate how many kmol of NO are produced, using the limiting reactant moles:
51.12 kmol NH₃ * [tex]\frac{4kmolNO}{4kmolNH_3}[/tex] = 51.12 kmol NOFinally we convert kmol of NO to mass, using its molar mass:
51.12 kmol NO * 30 kg/kmol = 1533.6 kg NO(Please help, ASAP) How many grams are in 3.45x10^23 atoms of P?
one mole of P weights about 31 grams
in one mole there are 6.022*10^23 atoms
we use the rule of threes
6.022*10^23atoms......weight..........31 grams
3.45*10^23 atoms.........weight...........x grams
x=(3.45*10^23*31)/6.022*10^23
x=106.95/6.022=17.76 grams

Answer: [tex]1.25dm^3[/tex] of unreacted oxygen is left.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given volume}}{\text{Molar Volume}}[/tex]
[tex]\text{Moles of} CO_2=\frac{3.60dm^3}{22.4dm^3}=0.161moles[/tex]
[tex]\text{Moles of} O_2=\frac{7.25dm^3}{22.4dm^3}=0.324moles[/tex]
[tex]C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(l)[/tex]
According to stoichiometry :
3 moles of [tex]CO_2[/tex] = 5 moles of [tex]O_2[/tex]
Thus 0.161 moles of [tex]CO_2[/tex] =[tex]\frac{5}{3}\times 0.161=0.268moles[/tex] of [tex]O_2[/tex]
moles of [tex]O_2[/tex] left unreacted = (0.324-0.268) = 0.056
Volume of [tex]O_2[/tex] left unreacted = [tex]moles\times {\text {Molar volume}}=0.056mol\times 22.4dm^3/mol=1.25dm^3[/tex]
Thus [tex]1.25dm^3[/tex] of unreacted oxygen is left.

Why does the mass of steel wool increase after getting burned? Help pls
Answer:
heat and large amount of surface area
Explanation:
the heat and surface area allows the iron in the wool to combine with oxygen. by doing this it increases the mass of the steel wool
The mass of steel wool increases after burning because it reacts with oxygen in the air, leading to the formation of iron oxide.
After burning, steel wool's bulk grows due to the oxidation process. Iron oxide, also referred to as rust, is created when steel wool burns when it comes into contact with oxygen from the air.
The steel's iron reacts chemically with the oxygen to create iron oxide, which is heavier than the original iron. As a result of going through the oxidation process and becoming iron oxide, steel wool gains bulk.

In the modern periodic table, which of the following represents the last pair of elects for which Newlands' Law of Octaves would hold true?
1. AI and GA
2. AI and SI
3. NE and AR
4. MG and CA
Answer: Mg and Ca
Explanation:
In the modern periodic table, Mg and Ca are the last pair of elects for which Newlands' Law of Octaves would hold true.
Law of Octaves is the generalization that was made by Newlands. It states that when chemical elements are arranged based on their increasing atomic weight, then the ones that have the same chemical and physical properties will occur after an interval of seven elements.
In such a case, every eighth element will have identical properties when the elements in the periodic table are arranged based on their atomic masses.
Based on the above information, Magnesium (Mg) has an atomic number of 12 while Calcium (Ca) has an atomic number of 20. Therefore, the elements follow the law of Octaves as they have a difference of 8 in their atomic numbers.
