For an imaginary closed economy, T = $5,000; S = $11,000; C = $48,000; and the government is running a budget surplus of $1,000. Then
Based on the information given, the private savings will be $10000 and the gross domestic product is $63000.
From the information given, he following can be gotten:
T = $5,000S = $11,000C = $48,000Budget surplus = $1000Since, S = Y - C - G
11000 = Y - 48000 - G
Y - G = 48000 + 11000
Y - G = 59000
Budget surplus = T - G = 1000
5000 - G = 1000
G = 5000 - 1000 = 4000
The GDP will be:
Y - G = 59000
Y - 4000 = 59000
Y = 59000 + 4000 = 63000
Private savings = Y - T - C
Private savings = 63000 - 5000 - 48000
Private savings = 10000

a. Anna's chemistry class is going to be experimenting with AgNO3 today, which
can stain hands and clothes. Anna is concerned about her jewelry, so as she
gets ready for school, she removes her gold (Au) ring andreplaces it with a
cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (3 points)
Answer:
No. While gold would not react with a silver nitrate solution, nickel would.
Explanation:
Refer to the metal reactivity series.
Reactivity: [tex]\text{Gold} < \text{Silver} < \text{Nickel}[/tex].
Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.
However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.
Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.
What is the molarity of aqueous lithium bromide if 25.0 mL of LiBr reacts with 10.0 mL of 0.250 M Pb(NO 3) 2
The molarity of aqueous lithium bromide, LiBr solution is 0.2 M
We'll begin by calculating the number of mole of Pb(NO₃)₂ in the solution.
Volume = 10 mL = 10 / 1000 = 0.01 L Molarity of Pb(NO₃)₂ = 0.250 MMole of Pb(NO₃)₂ =?Mole = Molarity x Volume
Mole of Pb(NO₃)₂ = 0.25 × 0.01
Mole of Pb(NO₃)₂ = 0.0025 mole
Next, we shall determine the mole of LiBr required to react with 0.0025 mole of Pb(NO₃)₂
Pb(NO₃)₂ + 2LiBr —> PbBr₂ + 2LiNO₃
From the balanced equation above,
1 mole of Pb(NO₃)₂ reacted with 2 mole of LiBr.
Therefore,
0.0025 mole of Pb(NO₃)₂ will react with = 2 × 0.0025 = 0.005 mole of LiBr
Finally, we shall determine the molarity of the LiBr solution
Mole = 0.005 mole Volume = 25 mL = 25 / 1000 = 0.025 L Molarity of LiBr =?Molarity = mole / Volume
Molarity of LiBr = 0.005 / 0.025
Molarity of LiBr = 0.2 M

dubnium chloride chemical formula
Answer:
Db
Dubnium/Symbol
Explanation:
please mark my answer in brainlist plz
Answer:
DbCl5
Explanation
Dubnium has 2 electron in 7s orbital and 3 electron in 6d orbital. Because Dubnium is synthetically produced with atomic number of 105, it is highly radioactive and quickly decay. Like other transition, it can have different oxidation state and it is assumed that dubnium have +3,+4,+5 oxidation state number(that most likely involves electron from 6d orbital). Hence chloride ions with -1 oxidation number would react to form Dubnium Chloride as DbCl3, DbCl4, and DbCl5. Now it is highly unlikely these compounds can really be formed. However if you read nature chemistry article https://www.nature.com/articles/nchem.2610, there is mention that DbCl5, DbBr5, and DbOCl3 may be expected to form.
Which is warmer -30C or -30 F?
-30°F is warmer than -30°C.
The -ve sign is used when the temperature drops down. Celsius is the greater unit. By converting, -30°F = -1.11°C (approx.) We know that, -1.11 > -30. So, -30°F (-1.11°C) is warmer than -30°C.
Formula :-
(x°C × 9/5) + 32 = y°F

Answer:
-30 c is warmer

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: CaCO,CaO+CO, He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer.
Answer:
According to conservation of matter, there should be equal amounts of all elements on both the reactant and product side.
Reactant:
1 Ca
1 C
1 O
Product:
1 Ca
1 C
3 O
Therefore, your friend is right because the law of conservation of matter is not followed in this chemical equation.

The three structures of glucose represent three different models, they are ball and stick model, Fischer projection and bond line notation, respectively.
Glucose is a type of simple sugar (carbohydrate) that does not further hydrolyze to give monosaccharides.
Ball and stick model: The atoms are portrayed as different colored balls connected to each other by "sticks." Fischer projection: The atoms on the sides of the plane are coming out of the plane, while the atoms at the ends are moving behind.Bond line notation: It is the most frequent representation method used; it lacks C and H bonds but instead depicts carbons through bends.Therefore, the three glucose structures reflect three distinct models: the ball and stick model, the Fischer projection, and the bond line notation, respectively.

A Carnot engine takes 2000 j of heat from a reservoir at 500 k, does some work and discards some heat to a reservoir at 350k . how much work does it do, how much heat is discarded, and what is it's efficiency?
Answer:
Explanation:
The Carnot engine is a theoretical or conceptual heat engine that has a higher efficiency than any practical or theoretical heat engine working between the same temperature range. The theoretical efficiency of a Carnot engine is considered as the highest efficiency and no practical heat engines can operate at that efficiency. A Carnot engine draws heat energy, performs useful work and the leftover energy is released from the working substance. According to the second law of thermodynamics, there must be a temperature gradient between the heat energy drawing point and release point of the heat engine.
