suppose a student poured equal volumes of water and naoh in two different flasks. he forgets to label his flasks and is confused
ArbitrLikvidat [17]

The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.

<h3>What is volume?</h3>

Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.

Volume is measures in litres.

When water is added to dilute acid like HCl, they become more dilute.

When NaOH is added to HCl, a neutralization reaction occurs.

The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.

The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

What is the absolute pressure in compartment d in atm g?
xenn [34]
Atmospheric pressure from barometer = (9810) × (13.6) × (0.720) = 96060 Pa = 96.06 kPa Absolute pressure in compartment A, 496.06 kPa P = P + P abs, A gauge, A atm = 400 + 96.06 = Absolute Pressure from barometer

What two factors determine whether a molecule is polar or not?
Bad White [126]

Answer:

electronegativity of bonded atoms and shape.

Explanation:

if the shape of molecule is symmetric it will non polar. The polar molecules are trigonal in shape.

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion and compound is polar.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive and compound will polar.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
