The correct answer is D. They may kick up dust and pollute Earth's atmosphere.

Explanation:

The impact of a large asteroid or comet is a major event that leads to major changes in ecosystems. One of the effects that can be expected is an important increase in dust because one of the components of asteroids and comets is dust, which would be released during the impact. Also, this dust might interact with components from the soil and the atmosphere creating a cloud, acting as a pollutant. According to this, the expected effect is "They may kick up dust and pollute Earth's atmosphere"

what property of the noble gases most likely prevented the gases from being readily/easily discovered?
Vlad [161]

These gases very rarely react, with others and also noble gases are odourless and colourless.

Explanation:

  • Noble gases will not react with anything so that is the reason why they are known as an inert gas.
  • Noble gases are present in group 18 on the periodic table and following the rule of the octet which is they completed their orbital by s2p6 which is the highest energy level.
  • Most elements are discovering through their reactivity with the other elements, commonly with oxygen. In the case of a noble gas, it is difficult for a scientist to work with the gases which have very less or no chemical property in terms of their reactivity.

Which of the following is not equal to 0.1 centimeters?
Anon25 [30]

Answer:

c) 10 millimeters (mm)

Explanation:

The unit conversions are as follows:

1 cm = 10 mm (millimeter)

1 cm = 0.01 m (meter)

1 cm = 0.00001 km (kilometer)

1 cm = 10000 μm (micrometer)

Based on the above conversions:

0.1 cm = \frac{10 mm*0.1 cm}{1 cm} = 0.1 mm

0.1 cm = \frac{0.01 m*0.1 cm}{1 cm} = 0.001 m

0.1 cm = \frac{0.00001 km * 0.1 cm}{1 cm} = 0.000001 km

0.1 cm = \frac{10000 um*0.1cm}{1 cm} =1000 um

Therefore, 0.1 cm = 10 mm is incorrect instead it is 0.1 mm

What are the concentrations of sugar
mariarad [96]
The easiest way to answer this question is to first figure out the molar mass of the sugar in question. To do this multiply the number of individual atoms for a given element by its atomic mass. 12 X 12.01 g/mol = 144.12 g/mol C. 22 X 1.008 g/mol = 22.176 g/mol H. 11 X 16.00 g/mol = 176.00 g/mol O.
