Answer and

Explanation:

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs

Sodium chloride is composed of molecules that are stable when dry. In water, the atoms of the molecules separate from each other

astra-53 [7]

The molecules of Sodium chloride holds a chemical bond to become stable when dry is an ionic bond.

<h3>What are chemical bonds?</h3>

The chemical bonds are those which holds the atoms of molecules together and creates a temporary connection between them.

The three major types of chemical bonds are:

Ionic bonds
Covalent bonds
Metallic bonds

<h3>What are ionic bonds?</h3>

The ionic bonds generally occurs in between a metal and a nonmetal ions.

The atoms share electrons in between them to become stable, forms ions. Due to electric attraction between these ions forms a bond between them. That bond is called as Ionic bond.

<h3>The type of chemical bond in Sodium chloride:</h3>

Sodium chloride - NaCl

Where Na(sodium) forms Na⁺ ion(metal) by sharing electrons with the chlorine atom and Cl(chlorine) forms Cl⁻ ion(non-metal).

So, due to the attraction between the anion and the cation, a bond is established between them. So, it is called Ionic bond.

Therefore, the chemical bond in Sodium chloride is an Ionic bond.

How many calories are required to raise the temperature of 105 g of water from 30.0°c to 70.0°c?

ioda

<span>4.200 calories. The formula is rise in heat (H) = the specific heat capacity (c) * rise in heat in degrees Fahrenheit (T) and volume of liquid (m) . H= cTm. Water, the typical comparison, has a specific heat capacity of 1. So to raise the Fahrenheit temperature of 105 grams of water 40 degrees, you multiply 105 * 40 * 1 = 4,200.</span>

The titration of 25.00 ml a 0.125 m hclo4 solution requires 27.07 ml of koh to reach the endpoint. what is the concentration of

agasfer [191]

Answer : The concentration of the $KOH$ is, 0.115 M

Explanation :

Using dilution law,

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1$ = basicity of an acid = 1

$n_2$ = acidity of a base = 1

$M_1$ = concentration of $HClO_4$ = 0.125 M

$M_2$ = concentration of KOH = ?

$V_1$ = volume of $HClO_4$ = 25 ml

$V_2$ = volume of NaOH = 27.07 ml

Now put all the given values in the above law, we get the concentration of the $KOH$ .

$1\times 0.125M\times 25ml=1\times M_2\times 27.07ml$

$M_2=0.115M$

Therefore, the concentration of the $KOH$ is, 0.115 M

The study of Mixture

Nitella [24]

Answer:

Mixtures can be either homogeneous or heterogeneous. A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water. A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water.

Give the number of significant figures in this number: 7.8 x 10¹²

denis-greek [22]

The number is written in scientific notation.

The significant figures are the numbers known precisely plus 1 digit that is uncertain.

When the numbers are expressed in scientific notation all the digits before 10^n are significant.

So, 7 and 8 are significant figures and the answer is that the number of significant figures is 2.

Answer: 2
