Some baking soda and vinegar were weighed separately and the weights added together. The two substances are mixed and a chemical

reaction occurred, producing carbon dioxide, sodium acetate, and water. When the three new substances are weighed and the weights total, which of the following will be true?
A. The original weight will be more because there was more mass.

B. The new weights will be more because there is more mass

C. The two weights will be equal, because the mass is the same.

Which instrument below is used to measure an intensive property?
Andrei [34K]

An intensive property is the physical characteristics that have an independent magnitude. The thermometer can be used to measure the temperature. Thus, option C is correct.

<h3>What is an intensive property?</h3>

An intensive property has been constituted of the parameters that are not dependent on the size and the mass of the sample. Density, pressure, and temperature are some intensive properties.

The first image shows a weighing balance, the second shows a volumetric cylinder, and the fourth shows a ruler used to measure mass, volume, and length respectively, which are extensive properties.

Therefore, option C. thermometer measures temperature, which is an intensive property.

Using the VSEPR theory , what would the representation mean A central atom with 2 connected atoms atom with I lone pair of Jone
VLD [36.1K]

Answer:

The molecule has a bent geometry

Explanation:

Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.

Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.

The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.
