How many moles of solute particles are present in 1 ml of aqueous 0.020 m (nh4)2co3?

Chemistry

6 0
Vs = 1.0 mL = 0.001 L
c((NH4)2CO3) = <span>0.02 M
n(</span>(NH4)2CO3) = ?

For the purpose, here we will use the next equation:

c=n/V ⇒ n=cxV

n((NH4)2CO3) = 0.02M x 0.001L 

n((NH4)2CO3) = 2x10⁻⁵ mole of (NH4)2CO3 is presented in the solution

PLEASE ANSWER “Tessa uses a toy slingshot to launch a tennis ball across the park for her dog to fetch. For her first launch, sh
Inessa05 [86]

The third launch ( with 300 N force) had  the greatest acceleration of the tennis ball

<h3>Further explanation  </h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

\large{\boxed{\bold{a=\frac{\sum F}{m}}}

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

From the above equation it has been shown that the force acting on the object is directly proportional to its acceleration, so <em>the greater the force exerted on the object, the greater the acceleration of the object produced.</em>

<h2>Question no 1:</h2><h2>Answer:</h2>

The correct answer is option A which is Sarah is correct because genetic diversity occurs over a long period of time.

<h3>Explanation:</h3>
  • Genetic diversity is a large number of allelic combinations for a trait in specie in a population.
  • Genetic diversity is caused due to mutations or random breeding in a specie.
  • It is good for the adaptation of specie in an environment, due to diverse in genotypes and phenotype of a trait.
<h2>Question number 2:</h2><h2>Answer:</h2>

The correct answer is option B which is the species will adapt to the changes.

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • If the environment changes, the first thing a specie do is an adaptation to that change in the environment.
<h2>Question 3.</h2><h2>Answer:</h2>

The correct answer is option D which is, "The spines of a cactus protect it from animals".

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • So the plant of cactus was in danger due to animals. So the start growing spines in response to animals.
  • Hence the correct answer is option D.
<h2>Question 4.</h2><h2>Answer:</h2>

The correct answer is option B which is, "Marie's plant will lean toward the sun so that it can get the most sunlight".

<h3>Explanation:</h3>
  • The plant will lean towards the sun light by the mechanism of phototropism.
  • Phototropism is the mechanism of growth of the plant in a specific direction in the response of light.
  • There are two types of phototropism.
  • One is a positive phototropism in which plant grows towards the light.
  • The other is negative phototropism in which plant grows away from the light.
  • In this question,the plant will do positive tropism.
<h2>Question no. 5</h2><h2>Answer:</h2>

The correct answer is option B which is, "The dodo bird could not adapt quickly to the challenges of the environment".

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • So the dodo could not adopt to the environment. For the positive adaption of survival, they should be afraid of sailors but the would not afraid of a sailor.
  • Due to which they went extinct.

A helium-filled balloon has a volume of 2.48 L and a pressure of 150 kPa. The volume of the balloon increases to 2.98 L after yo
Tema [17]

Answer:

THE NEW PRESSURE OF THE HELIUM GAS AT 2.98 L VOLUME IS 124.8 kPa.

AT AN INCREASE ALTITUDE, THERE IS A LOWER PRESSURE ENVIRONMENT AND THE HELIUM GAS PRESSURE DECREASES AND HENCE AN INCREASE IN VOLUME.

Explanation:

The question above follows Boyle's law of the gas law as the temperature is kept constant.

Boyle's law states that the pressure of a fixed mass of gas is inversely proportional to the volume, provided the temperature remains constant.

Mathematically, P1 V1 = P2 V2

P1 = 150 kPa = 150 *10^3 Pa

V1 = 2.48 L

V2 = 2.98 L

P2 = ?

Rearranging the equation, we obtain;

P2 = P1 V1 / V2

P2 = 150 kPa * 2.48 / 2.98

P2 = 372 *10 ^3 / 2.98

P2 = 124.8 kPa.

The new pressure of the gas when at a height which increases the volume of the helium gas to 2.98 L is 124.8 kPa.
