Answer:

If matter is heated and thus its temperature rises more and more, it can be seen that the particles contained in it move ever faster – be it the relatively free movement of the particles in gases or the oscillation around a rest position in solids. The temperature of a substance can therefore be regarded as a measure of the velocity of the particles it contains. With a higher temperature and thus higher particle

Jewelry is commonly weighed in carats. five carats are equivalent to one gram. how many grams of gold are contained in a 24-cara

11111nata11111 [884]

Answer: b. 4.8 g

Explanation:

Given : 5 carats = 1 gram

Thus if 5 carats is equivalent to = 1 g

24 carats is equivalent to = $\frac{1g}{5carat}\times 24carat=4.8g$

Thus 4.8 grams of gold are contained in a 24-carat gold chain.

As of January 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 yesrs of operating 104 nuclear power plants.

goblinko [34]

Answer: a. 0.8 tons p. month.

Explanation:

Given: Total nuclear waste = 60,000 metric tons

Time take = 60 years = 12 x 60 months [ 1 year = 12 months]

= 720 months

Total nuclear power plants = 104

Now , Average waste produced by each plant = $\dfrac{\text{Total waste}}{\text{Time x Number of plants}}$

$=\dfrac{60000}{720\times104}\approx0.8\text{ tons per month.}$

Hence, 0.8 tons p. month is produced by each plant.

So, option a. is correct.

Select the more electronegative element in each pair.a.Cl or Fb.Se or Oc.N or Asd.Na or Mg

liubo4ka [24]

Answer:

The answer to your question is below

Explanation:

Electronegativity is a measure of how strongly atoms attract electrons to themselves.

Process

Look for the electronegativity of each element and compare.

a) Cl = 3.16 F = 3.98 Fluorine has a higher electronegativity

b) Se = 2.55 O = 3.44 Oxygen has a higher electronegativity

c) N = 3.04 As = 2.18 Nitrogen has a higher electronegativity

d) Na = 0.93 Mg = 1.31 Magnesium has a higher electronegativity
