Answer:
The water at 38 °C has faster-moving molecules than the sample at 295 K.
Explanation:
Converting the temperature, 295 K from Kelvin to Celsius:
295 - 273 = 22°C
⇒The boiling point of water is 100°C and its melting point 0°C
⇒When we compare water at those 2 different temperatures ( 22°C and 38°C) we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
⇒The difference in temperature between water at the 2 given temperatures = 38°C - 22°C = 16°C
Water at 38°C is at a higher temperature and so is warmer than water at a lower temperature of 22°C.
At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.
Answer:
The correct statement is : It results in an equilibrium mixture of reactants and products.
Explanation:
A reversible chemical reaction is one that occurs in both directions, that is, of the reagents to generate products and vice versa. In synthesis, they are incomplete reactions since the reagents are not consumed in their entirety, since the products react to generate them again.
Answer: Option (B) is the correct answer.
Explanation:
When two circles are of same same then they are known as congruent circles.
Whereas a rectangle is a kind of parallelogram with all sides equal to 
.
Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.
Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.
The correct answer is cyanate.
The polyatomic ion with the formula CN⁻ is called cyanate. A polyatomic ion has two or more atoms bonded together.
CN⁻ contains the cyano functional group wherein a carbon atom forms a triple-bond to a nitrogen atom. CN⁻ is a polyatomic anion that is present in inorganic compounds.
We need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.
<h3>
What is Lewis dot structure?</h3>
Lewis dot structure is defined as the visual representation of atoms' electrons using a diagram. It describe the bonds that exist between a molecule's lone pairs of electrons and its atoms.
A lone pair of electrons on the atom with the formal charge of 1- can typically be converted into a bonding pair that is shared with the atom that has the formal charge of 1+ in order to reduce the formal charges when they are present.
Thus, we need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.
