1. What are some similarities between the dogs pictured? What are some differences? Among these dogs we find that all come from the same family: the canids, and also all can be adopted as pets. However, each one has different physical characteristics such as size, color and type of hair and also different personalities.

2. What are some ways you can divide these dogs into groups?

They can be divided by size (small breeds and large breeds), by color or by the type of hair they have.

3. How could you improve your dichotomous key

You can know how to classify them better by doing research that exceeds the general, looking for more specific aspects that are related to the main characteristics of dogs.

4. Why is it important to classify things?

It is important to classify in order to have a better understanding of a concept. In this case, in order to better understand the specific characteristics of each dog.

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.

Determine from the balanced chemical reaction if the derived mole ratio is correct or incorrect.
DIA [1.3K]

Answer:

Balanced reaction: 4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O

The mole ratio (4 moles Zn/5 moles H_{2}O) is correct.

Explanation:

Oxidation: Zn\rightarrow Zn(NO_{3})_{2}

Balance N and O: Zn+2NO_{3}^{-}\rightarrow Zn(NO_{3})_{2}

Balance charge: Zn+2NO_{3}^{-}-2e^{-}\rightarrow Zn(NO_{3})_{2}    ................(1)

Reduction: HNO_{3}\rightarrow N_{2}O

Balance N: 2HNO_{3}\rightarrow N_{2}O

Balance H and O: 2HNO_{3}+8H^{+}\rightarrow N_{2}O+5H_{2}O

Balance charge: 2HNO_{3}+8H^{+}+8e^{-}\rightarrow N_{2}O+5H_{2}O  ............. (2)

[4\timesEquation-(1)] + [Equation-(2)]:

4Zn+8NO_{3}^{-}+2HNO_{3}+8H^{+}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O

\Rightarrow 4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O

So, balanced reaction: 4Zn+10HNO_{3}\rightarrow 4Zn(NO_{3})_{2}+N_{2}O+5H_{2}O

Hence the mole ratio (4 moles Zn/5 moles H_{2}O) is correct.

The ph of a solution with [h3o+] = 5.9 × 10-3 m, to the correct number of significant figures, is
alexira [117]
The  Ph of  a solution  with (H3O+) =  5.9  x10 ^-3M  is  calculated   as  below

Ph=  - Log  (H3O+)  concentration

that is Ph= -Log  ( 5.9  x10^-3)  =  2.2

the  solution is acidic since the  Ph is  less  than  7
