Answer:

The Manganese oxide would rather speed up the rate of reaction.

Explanation:

In this reaction, manganese oxide is the catalyst and catalyses the decomposition of hydrogen peroxide. Chemically this reaction can be written as:

2H_2O_2 -> O_2 + 2H_2O

MnO2 does not show itself in the equation because it is a catalyst.

A catalyst is a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence a catalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze.

The high-income economies of the world contain approximately <u>12%</u> of the world’s population and produce and consume <u>60% </u>of the world’s GDP.

Gross Domestic Product is a complete measure of U.S. economic activity. GDP measures the value of the very last goods and offerings produced in the u.s. (without double counting the intermediate items and services used up to provide them).

Gross domestic product is an economic measure of the market price of all of the very last goods and offerings produced in a selected term through international locations. Due to its complicated and subjective nature, this degree is regularly revised before being taken into consideration as a reliable indicator.

GDP may be calculated by means of adding up all the money spent by using consumers, agencies, and the authorities in a given duration. It may additionally be calculated by means of adding up all the money received by all of the contributors to the economy. In either case, the wide variety is an estimate of "nominal GDP."

Zielflug [23.3K]

Answer: Stimulating the aggregate demand in the economy.

Explanation:

When former President Obama took over the governing of the nation in 2009, the country was in the midst of one of the worst global depressions that it had ever been through. Employment was high and aggregate demand was low.

President Obama therefore embarked on an expansionary fiscal policy by passing the American Recovery and Reinvestment Act which was to target certain sectors of the economy with the view of increasing investment in those sectors and consumption so that Aggregate demand can be stimulated in the economy as those two things are components of Aggregate demand.

Alik [6]

Answer:

All answers are correct except Money Supply

Explanation:

Fiscal policy affects aggregate demand through government spending and taxes. Government may increase taxes to increase revenue or discourage the consumption of a product. On the flipside, they may reduce taxes to stimulate spending, redistribute income, increase aggregate demand among other objectives.

Money supply is a monetary policy and it is used by the central bank to achieve certain objectives (reduce inflation, stimulate growth, increase demand, etc.)

Government spending is a fiscal policy that government uses to achieve a set of objectives (i.e. to supply goods and services that are not provided by the market or private sector – construct bridges, provide health facilities, social programmes for the poor among others).

Taxes – Tax is a fiscal policy tool used by the government to generate revenue, encourage or discourage the consumption of certain products or affect aggregate demand through income redistribution.  

Trade policy could be in the form taxes (i.e. tariffs, import duties, custom duties among others). Trade policy is a fiscal policy as government can use it to control aggregate demand by placing embargo on the importation of certain products to reduce the demand of such products in the local economy.
