What type of policy does the Federal Reserve use to boast a slow growing economy?
Answer:
Tight monetary policy is an action undertaken by a central bank such as the Federal Reserve to slow down overheated economic growth. Central banks engage in tight monetary policy when an economy is accelerating too quickly or inflation—overall prices—is rising too fast.

Calculate the heat produced by hydrolysis of 65 kg of ATP (the molecular weight of ATP is 507.18 g/mol).
The heat produced by hydrolysis of 65 kg of ATP is -6.8 kJ.
Let's consider the thermochemical equation for the hydrolysis of ATP.
ATP + H₂O ⇒ ADP + Pi ΔG = -57 kJ/mol
We will convert 65 kg of ATP to moles using its molecular weight (507.18 g/mol).
[tex]65 \times 10^{3} g \times \frac{1mol}{507.18g} = 1.2 \times 10^{2} mol[/tex]
57 kJ of heat are released by the hydrolysis of 1 mole of ATP. The heat released by the hydrolysis of 1.2 × 10² moles of ATP is:
[tex]1.2 \times 10^{2} mol \times \frac{(-57kJ)}{1mol} = -6.8 \times 10^{3} J = -6.8 kJ[/tex]
-6.8 kJ is the heat produced by hydrolysis of 65 kg of ATP.

A 200.0 ml beaker filled with oil has a mass of 293.2 g. The mass of just the beaker is 130.2
g. What is the density of the oil?
Answer in a complete sentence. Show your work. Your final answer should have the cor-
rect number of sig figs. show work!
Answer:p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Explanation:
Density of a substance is the ratio of its mass to volume. The density of the oil filled in a 200.01 ml beaker is 0.815 g/ml.
What is density?Density of a substance is the mass per volume. Thus we het how much of its particles are located per one unit of volume.
Mathematically density can be written as mass/ volume. The mass of the beaker containing oil is given as 293.2 g. The mass of beaker itself is 130.2 g. Hence, mass of oil is 293.2 - 130.2 = 163 g.
Volume of the oil is 200 ml. Thus density is 163 g/200 ml = 0.815 g/ml.
Hence, the oil in the beaker with 200 ml volume and 163 g mass have a density of 0.815 g/ml.

The relationships among which variable quantities are expressed by the ideal gas law equation?
A. pressure, volume, temperature, number of moles
B. volume, temperature, number of moles, gas constant
C. pressure, volume, number of moles, mass
D. pressure, volume, temperature, molar mass
Answer:
A. Pressure, volume, temperature, number of moles
The relationships among pressure, volume, temperature, and the number of moles are expressed by the ideal gas law equation. Therefore, option A is the correct answer.
The ideal gas law equation is PV = nRT, where P represents the pressure of the gas, V represents its volume, n represents the number of moles of gas present, T represents its temperature, and R is the ideal gas constant. This equation describes the behavior of an ideal gas at standard temperature and pressure (STP).
By manipulating the ideal gas law equation, we can calculate various properties of gases, including their density, molar mass, and molecular weight. This equation is widely used in chemical engineering, thermodynamics, and other fields that deal with gases.
Thus, option A is correct.

How much heat is necessary to 20g of water at 100*C into steam at 100*C?
Answer:
To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy.
The amount of heat which is required for a phase change of a substance without any change in temperature is known as latent heat. Here the amount of heat required is 10,800 calories.
What is heat capacity?The heat capacity of a substance or a system is defined as the amount of heat required to raise its temperature through 1°C. It is denoted by C. The specific heat capacity is the amount of heat required to raise the temperature of 1 gram of the substance through 1°C.
The equation to calculate the heat required is:
Q = mc (T₂ - T₁) + mL₁
L = Latent heat of vaporization of water
m = mass
c = specific heat capacity
T₂ = Final temperature
T₁ = Initial temperature
T₂ - T₁ = 100 - 100 = 0°C
Q = 20 g × 1 cal /g°C × 0°C + 20 g × 540 cal/g
Q = 10,800 calories
Thus the amount of heat required is 10,800 calories.

How does increasing the temperature affect a reaction?
A. An increase in temperature slows down the reaction.
B. An increase in temperature increases the reaction rate.
C. An increase in temperature lowers the reaction's activation energy.
D. An increase in temperature changes equilibrium concentrations.
SUBMIT
Answer:
b
Explanation:
The concept Arrhenius equation is used here to determine the temperature dependence of the rate of a reaction. An increase in temperature increases the rate of a reaction. The correct option is B.
What is Arrhenius equation?The rate of a chemical reaction is affected by the factors like temperature and activation energy. The influence of these factors on the rate of the reaction is explained by the Arrhenius equation.
The equation is given as:
[tex]k = A. e^{-} ^{E_{a} } /RT[/tex]
k - Rate constant
A - Frequency factor
Eₐ - Activation energy
R - Gas constant
T - Temperature
Since 'Temperature' appears in the denominator of the negative power of the exponential factor of the equation, it is evident that an increase in temperature increases the value of rate constant and thereby increases the rate of the reaction.
Thus the correct option is B.

Convection currents in the atmosphere influence many weather patterns. What property of the air has the most influence on convection currents?
1. The direction of the wind
2. The velocity of the wind
3. The temperature of the air
4. The mass of the air
Convection currents are largely influenced by air temperature. A low-pressure area is produced when air is heated because it becomes less dense and rises.
What effect on the climate does convection have?For instance, the air above the Earth heats and rises as its surface warms from the sun. This air may continue to rise while cooling and producing cumulus clouds if the conditions allow.
How do air masses respond to convection currents?Climate-affecting wind patterns are driven by convection currents. Convection currents are used to shift air masses. There are two different kinds of air masses: warm and cold. From higher latitudes to lower latitudes, cold air masses travel.
