Answer:

Honey is an homogeneous mixture

Salsa is an heterogeneous mixture

Explanation:

Honey is a sweet uniformly colored liquid that can be of a dark variety or of clear golden color. Honey is made in nature by bees from flower nectar and is used as a food additive or sweetener

Honey is a homogeneous mixture because the concentration of the components of honey are uniformly distributed throughout the mixture. Every portion has the same concentration of components

Salsa is a sauce made by mixing chopped tomatoes, onions, chilies, lime juice and seasoning and therefore consists of both solid and liquid components mixed in varying proportion such that part will have continuous  that comes in between different types of solid and no two parts have exactly the same composition

Therefore, salsa is an heterogenous liquid.

A solution is made using 200.0 mL of methanol (density 0.792 g/mL) and 985.1 mL of water (density 1.000 g/mL). What is the mass
DaniilM [7]

<u>Answer:</u> The mass percent of methanol in solution is 13.85 %

<u>Explanation:</u>

To calculate the mass of water, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

  • <u>For water:</u>

Density of water = 1.000 g/mL

Volume of water = 985.1 mL

Putting values in above equation, we get:

1.000g/mL=\frac{\text{Mass of water}}{985.1mL}\\\\\text{Mass of water}=(1.000g/mL\times 985.1mL)=985.1g

  • <u>For methanol:</u>

Density of methanol = 0.792 g/mL

Volume of methanol = 200.0 mL

Putting values in above equation, we get:

0.792g/mL=\frac{\text{Mass of methanol}}{200.0mL}\\\\\text{Mass of methanol}=(0.792g/mL\times 200.0mL)=158.4g

To calculate the mass percent of methanol, we use the equation:

\text{Mass percent of methanol}=\frac{\text{Mass of methanol}}{\text{Mass of solution}}\times 100

Mass of solution = [158.4 + 985.1] g = 1143.5 g

Mass of methanol = 158.4 g

Putting values in above equation, we get:

\text{Mass percent of methanol}=\frac{158.4g}{1143.5g}\times 100=13.85\%

Hence, the mass percent of methanol in solution is 13.85 %

Ionic compounds are formed from ionic bonds, whereby an electron is transferred from the metal cation to the nonmetal anion. Ion
Karolina [17]

Answer:

NaI

Explanation:

In I₂, HI and IBr, both atoms are nonmetals and they form covalent bonds in which electrons are shared.

In NaI, Na is a metal and I a nonmetal, so they form an ionic bond, where Na loses an electron to form Na⁺ and I gains an electron to form I⁻.  Anions and cations are attracted to each other through electrostatic forces.

Since ionic bonds are stronger than covalent bonds, more energy is required to break them in the melting process, thus having higher melting points.

All in all, NaI is the one with the highest melting point.

Which temperature is the hottest, 200°C, 200°F or 200 Kelvin?
gogolik [260]

Answer:

200 °C

Explanation:

Let’s convert all the temperatures to the same scale, say, Celsius.

<em>Celsius</em>

Water boils at 100 °C, so 200 °C is the temperature of <em>superheated steam</em>.

<em>Fahrenheit </em>

Water boils at 212 °F, so 200 °F is <em>just below the boiling point of water</em>.

C = \frac{5 }{ 9}(F-32)

C = \frac{5 }{ 9}(200-32) = \frac{5 }{ 9}\times168 = 93 ^{\circ}\text{C}

<em>Kelvin </em>

Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so

200 K is <em>well below the melting point of ice</em>.

C = K – 273.15

C = 200 -273.15 = -73 °C

Thus, 200 °C is the hottest temperature.
