The correct answer is D. Make it warmer

Explanation:

One of the most important factors that regulate temperature on Earth is the action of greenhouse gases such as carbon dioxide because these gases trap and reflect back part of the radiation from the sun, which creates a warm environment that is ideal for life. This implies, an increase of carbon dioxide due to the burning of fossil fuels, industries, etc. will lead to more radiation staying on Earth, and therefore there would be an increase in Earths' temperatures. Moreover, this situation might affect negatively life as many species cannot prosper in higher temperatures. According to this, burning fossil fuels will make Earth warmer.

Suppose you were to make a ring from a single strand of gold atoms. How many gold atoms would be required to make such a ring? H
Rudiy27
Let us assume that the ring is a size 7 ring, which has a circumference of 54.3 millimeters. Converting this to centimeters, the circumference of the ring is:

54.3 mm = 5.43 cm

Now, we determine the number of gold atoms that will be present in this:

5.43 / 1 x 10⁻⁹

There will be 5.43 x 10⁹ atoms


We now determine the number of moles this is by:

one mole = 6.02 x 10²³ atoms

Moles = 5.43 x 10⁹ / 6.02 x 10²³ 
Moles = 9.01 x 10⁻¹⁵ moles

The molar mass of gold is 197 g/mol

The mass is 9.01 x 10⁻¹⁵  * 197

The mass of the strand is 1.76 x 10⁻¹² grams

Determine the rate of a reaction that follows the rate law rate = k a m b i where
ikadub [295]
(missing part of your question):
when we have K = 1 x 10^-2 and [A] = 2 M & [B] = 3M & m= 2 & i = 1
So when the rate = K[A]^m [B]^i
and when we have m + i = 3 so the order of this reaction is 3 So the unit of K is L^2.mol^-2S^-1
So by substitution:
∴ the rate = (1x 10 ^-2 L^-2.mol^-2S^-1)*(2 mol.L^-1)^2*(3mol.L^-1)
                 = 0.12 mol.L^-1.S^-1

Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s
inessss [21]

The pressure of the gas used in the weather balloon increases to expand the balloon.

Explanation:

  • Weather balloons contain the boxes where the weather measurement instruments are present that is attached to the large balloon.
  • Weather balloon uses gases like Hydrogen or Helium. When the weather balloon rises to the atmosphere, the air pressure decreases. This leads to the increase in the pressure of hydrogen or Helium gas used in the weather balloon. This expands the balloon.
  • The gas particles hits the balloon container and generates the pressure. The increase of pressure thus helps the weather balloon to move in a constant speed through the atmosphere.
