Hello,
They both emits mainly gamma rays. Which makes the emission a transition between the levels!
Answer: Thus the correct coefficient for sodium chloride is 2.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:
Thus the correct coefficient for sodium chloride is 2.
In order to do conversion on these types of problems. <span>
1.You first have to determine the relationship and the current unit and the target unit which it will be converted into.</span> <span>
2.In this case feet to meters and seconds to minutes</span> <span>
3.Determine the conversion rate: </span>1mi =1609 m<span /> and 1 h = 3600 sec; <span>
4.You first calculate: 1230 m x </span>1 mi/1609 m = 0.764 mi/s
<span>5.<span>Next, is the time which is 0.764 mi/s x 3600s/1hr = </span></span><span>2752.02 mi/h

Greenhouse effect is the natural phenomenon which makes the Earth's atmosphere favorable for any form of life. As the sun's rays radiates into the atmosphere, some are deflected while some are absorbed. The Earth reflects this back, causing the heat to be trapped. At night, this keeps the Earth warm enough. Without the greenhouse effect, nights would be too cold and days would be too hot that life cannot be sustained.
