Answer:

<u>Reliable science refers to the approximate result that is obtained after conducting various methods for the same experiment</u>. All scientific results are based on the evidences that are obtained by conducting experiments. This derived value confirms the accuracy of the result. The more similar the result obtained by approaching various scientific methods in a particular experiment, the more is the reliability. A reliable scientific experiment shows a minimum error.

<u>Reliable science includes an experiment with proper observation, careful reading, gathering the proper information and modeling with a justifying conclusion</u>.

If the molar heat of fusion of water is 6.01

Zolol [24]

Answer : The heat energy required to melt 2 kg of ice was, 667.7 kJ

Explanation :

First we have to calculate the moles of ice.

$\text{Moles of ice}=\frac{\text{Given mass ice}}{\text{Molar mass ice}}=\frac{2kg}{18g/mol}=\frac{2000g}{18g/mol}=111.1mol$

Now we have to calculate the heat energy.

As, heat energy required to melt 1 mole of ice = 6.01 kJ

So, heat energy required to melt 111.1 mole of ice = 111.1 × 6.01 kJ

= 667.7 kJ

Therefore, the heat energy required to melt 2 kg of ice was, 667.7 kJ

Which group (give the number) is characterized by 5 valence electrons in the configuration<br> s²p3?

Ivahew [28]

<h3>Answer:</h3>

Group 5A

<h3>Explanation:</h3>

Elements in the periodic table are arranged into columns known as groups and rows known as periods.
Elements in the same group share similar chemical properties.
For example, elements in group 5A have five valence electrons with the most high energy level with a configuration of s²p³.
Elements in group 5A include nitrogen and phosphorus among others.
