Which of the following concerning solutions is/are correct? 1. The solvent in a mixture of gases is generally considered to be t
pshichka [43]

Answer: 1. The solvent in a mixture of gases is generally considered to be the substance in greater amount. 2. The solid dissolved in a solution is known as the solute. 3. Solid solutions are called alloys.

Explanation:

A binary solution is made up of two components ,called as solute and another as solvent.

A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase. A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.

Usually in liquid solutions , solid acts as solute and liquid acts as solvent. For example: In salt solution, salt is the solute and water is the solvent.

Solid solutions contains solid as solute and solid as solvent. These are called as alloys. For example : In brass, zinc is the solute and copper is the solvent.

What happens in this reaction and why? <br><br> hept-3-yne + Br2 --&gt;
maw [93]

Here we have to explain and predict the product of the reaction between hept-3-yne and bromine (Br₂)

The reaction between hept-3-yne and bromine produces <em>trans</em>-3,4-dibromo-3-heptene.

The reaction between the unsaturated hydrocarbon with halogen remove the unsaturation in the molecule and produces di halo compound. The reaction proceed through the formation of bromonium ion.

In this reaction as the unsaturation present in the middle of the alkyl chain i.e. hept-3-yne. The reaction will stop after the formation of di-halo compound with one double bond as shown in the figure.

The product will be exclusively trans product as the bromine is a bulky group and the formation of bromonium ion (intermediate) will be one side of the unsaturated compound.

Why is creativity important in constructing scientific explanations?
poizon [28]

D. Sometimes it is necessary to put forth new theories to explain  experimental results,

Explanation:

Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.

Theories are explanation of scientific observations.

  • Most scientists are critical and creative thinkers.
  • They must be able to come up with a wide range of possible explanation to explain their findings.
  • The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
  • Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?
andreev551 [17]

Answer: The frequency of the wave is 0.5 hertz.

Explanation:

\nu =\frac{c}{\lambda }

\nu = Frequency of the wave

c = speed of the light in m/s

\lambda = Wavelength of the wave.

Here in question we are given with speed of the infrared light. So, we will replace the value of speed of light(c) from the given value of the speed of the infrared light.

Speed of infrared light = 6 m/s

\nu =\frac{\text{speed of infrared light}}{\lambda }=\frac{6 m/s}{12 m}=0.5 hertz

The frequency of the wave is 0.5 hertz.
