Answer:
smaller political units maintaining their sovereignty
Explanation:
Confederation is the name given to a country that is a federation, but the states that make up that country maintain their sovereignty, separate from the power of the federal government. In this case, to maintain a confederation it is essential that the smaller political units, the states, maintain their sovereignty. This is different from a federation, because in a federation, states lose sovereignty, transferring it to the federal government.
It stared 30 years ago it appeared in the news .Indeed, Svante Arrhenius, the pioneering Swedish scientist who in 1896 first estimated the scope of warming from widespread coal burning, mainly foresaw this as a boon, both in agricultural bounty and “more equable and better climates, especially as regards the colder regions of the Earth.”
There were scattered news reports through the decades, including a remarkably clear 1956 article in the New York Times that conveyed how accumulating greenhouse gas emissions from energy production would lead to long-lasting environmental changes. In its closing the article foresaw what’s become the main impediment to tackling harmful emissions: the abundance of fossil fuels. “Coal and oil are still plentiful and cheap in many parts of the world, and there is every reason to believe that both will be consumed by industry so long as it pays to do so.”
It's true, Venezuela is the biggest supplier of oil to the U.S, also other countries like Saudi Arabia, Canada, Nigeria and Mexico.
Answer:
5g will be left
Explanation:
Uranium 235 have a half-life of 700 million* years. This means that the element will decay to half its initial amount by that time. So if I start with 10g chunk of 235 Uranium, after 713 million years, only half of it (5g) will be remaining.
*the exact half life of Uranium 235 is 703,800,000 years.
