Define the problem

Explanation:

The first step in a scientific investigation is to define the problem at hand. Definition of a scientific problem makes a scientific investigations possible.

  • When preliminary observations are made about a phenomenon. A lot of questions as to why such things occur will arise.
  • From the question, we can state the problem and the likely causes.
  • The first portal in an inquiry is problem definition.
  • This would them lead to the formulation of a hypothesis which contains problem statement and likely causes.
  • The hypothesis leads to the design of an experiment from which investigations using experiments can be done.
  • The data from the experiments are collected and analyzed.

Crossing over Mitosis

Explanation:

A process called meiosis ensures siblings share just about 50% of their genotype. That's how siblings can have different DNA. Meiosis is a form of cell division that is only used to produce a special category of cells, called gametes.

Assume that you measured exactly 2.0 mL of the sodium chloride solution into a small test tube. How many moles of sodium chlorid
Lera25 [3.4K]

Answer:

0.034 mol (4dp)

Explanation:

Use the formula n = m/M where n= number of moles, m=mass in grams and M=molar mass in g/mol.

Therefore to find how many moles, divide the mass in grams (2) by the molar mass of sodium chloride which is 22.99+35.45

At 800 K, the equilibrium constant, Kp, for the following reaction is 3.2 × 10–7. 2 H2S(g) ⇌ 2 H2(g) + S2(g) A reaction vessel a
djverab [1.8K]

Answer:

0.008945 atm

Explanation:

In the reaction:

2H2S(g) ⇌ 2 H2(g) + S2(g)

Kp is defined as:

Kp = P_{H_{2}}^2P_{S_{2}} / P_{H_{2}S}^2

<em>Where P is the pressure of each compound in equilibrium.</em>

If initial pressure of H2S is 3.00atm, concentrations in equilibrium are:

H2S = 3.00 atm - 2X

H2 = 2X

S2: = X

Replacing:

3.2x10^{-7} = (2X)^2X / (3-2X)^2

3.2x10^{-7} = 4X^3 / 9- 6X+4X^2

0 = 4X³ - 1.28x10⁻⁶X² + 1.92x10⁻⁶X - 2.88x10⁻⁶

Solving for X:

X = 0.008945 atm

As in equilibrium, pressure of S2 is X, <em>pressure is 0.008945 atm</em>
