Which statement explains why many scientists believe that carbon dioxide has likely contributed more to global warming than othe

Sergeu [11.5K]

Answer:

C. Carbon dioxide has increased as a result of increased human activities.

Explanation:

THESE ARE THE OPTIONS FOR THE QUESTION BELOW

A. Carbon dioxide is emitted from fertilizers used in farming.

B. Other greenhouse gases trap more heat than carbon dioxide.

C. Carbon dioxide has increased as a result of increased human activities.

D. Carbon dioxide is emitted from commercial refrigeration.

Global warming can be regarded as

long-term heating of climate system of the Earth, this has been a point if observation even as far as pre-industrial period arround 1850. This global warming can be attributed to activities such as human activities as well as primarily fossil fuel burning, and as a result of this there is rise in heat-trapping, increase in greenhouse gas levels arround the atmosphere of the Earth. Human activities that brings about increase of Carbon dioxide concentration in the atmosphere are ;

✓ burning of oil as well as coal and gas,

✓deforestation

Hence, many scientists believe that carbon dioxide has likely contributed more to global warming than other greenhouse gases as a result of increase in Carbon dioxide which is as a result of increased human activities.

Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth's surface and reradiating it back to Earth's surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.

[20pts] I want to start counterfeiting American pennies. Each penny weighs 2.56g and I want $200.00 of pennies for my scheme. Se

Lera25 [3.4K]

Answer:

$\$200.00\times 100\dfrac{penny}{\$}\times \dfrac{2.56g}{penny}\times \dfrac{1molCu}{63.5gCu}\times \dfrac{2molAl}{3molCu}\times \dfrac{27gAl}{1molAl}$

Explanation:

The <em>dimensional analysis</em> helps you by focusing your attention into the units: you must set up the equation starting with the available units and add the factors with the units such that the cancelation of numerators and denominators ends up with the desired units: grams of aluminium in this case.

In this case, you start with a mass of 2.56 grams per penny, which is $2.56g/penny$ , whose value is $200.00 and want to end with the grams of

Aluminium needed.

Then, you must use the mole ratios derived from the chemical equation in a way that the units lead from grams of copper to grams of aluminium.

The equation is:

$2Al(s)+3CuCl_2(aq)\rightarrow 2AlCl_3(aq)+3Cu(s)$

From which, the mole ratio between copper and aluminium is:

$2molAl(s):3molCu(s)\\\\\dfrac{2molAl}{3molCu},or\\\\\\\dfrac{3molCu}{2molAl}$

You must also use the atomic masses of Cu and Al which are 63.5g/mol and 27g/mol respectively.

The equation is:

$\$200.00\times 100\dfrac{penny}{\$}\times \dfrac{2.56g}{penny}\times \dfrac{1molCu}{63.5gCu}\times \dfrac{2molAl}{3molCu}\times \dfrac{27gAl}{1molAl}$

You can check that afeter multiplying all the factors, the most units will cancel and the final units will be grams of Al.

Pavlova-9 [17]

Explanation:

GAAP is a generally accepted accounting principle in U.S. it refers to common sets of accepted accounting principle, standards, procedures that the companies and its accountants must follow in order to compile their financial statement.

IFRS are sets of international accounting standards That specify how the financial statements will disclose different types of transactions and other activities. The International Accounting Standards Board (IASB) issues IFRS which defines precisely how accountants are required to maintain and record their accounts. In an attempt to have an universal accounting system, IFRS was developed so that business and accounts can be interpreted from industry to industry, and country to country.
