How can acceleration occur?
prisoha [69]

Answer:

Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. Average acceleration is determined over a "long" time interval.

two factors that determine wether a molecule is polar are the types of atoms in the molecule and the ____ of the molecule
kolezko [41]

Answer:

Shape

Explanation:

Two factors that determine wether a molecule is polar are the types of atoms in the molecule and the <u>shape</u> of molecule.

Shape and polarity determine which type of compounds is.

if the shape of molecule is symmetric it will non polar. And it will dissolve in non polar solvent. 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.

The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.

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.

If the ectronegativity difference is 0.4 or less than this the compound will be non polar covalent compound and will behave different from polar compound.

What would a chemist most likely study about a car?
Karolina [17]

Answer:

I believe it's the chemical composition of the fuel and different fluids such as the coolant of the radiator

Explanation:

Chemists may discover more sustainable compounds that produce less waste material or that release more energy for the least amount of fuel. For coolants, fluids with greater heat retention that can absorb heat and direct it to the radiator in the most efficient manner. This is usually paired with engineering.
