The heart and blood vessels constitute the cardiovascular (circulatory) system. The blood circulating in this system delivers oxygen and nutrients to the tissues of the body and removes waste products from the tissues.

The blood vessels consist of

Arteries
Arterioles
Capillaries
Venules
Veins
All blood is carried in these vessels.

You are given three bottles labeled a, b, and

ElenaW [278]

Answer :Solid in bottle a is ionic, solid in bottle b is molecular and solid in bottle c is ionic.

Explanation :

Ionic compound is formed when a metal atom donates one or more electrons to a non metal. This results in the formation of a cation ( a positive ion) and an anion ( a negative ion). These ions are bonded to each other by electrostatic attraction.

The intermolecular forces in case of a an ionic compound are very strong.

The melting point of a substance depends on how strongly the molecules are attracted to each other. Stronger the forces, higher is the melting point.

Therefore ionic compounds always have very high melting points.

On the other hand, covalent compounds have weak intermolecular forces. Therefore they have low melting points.

Based on above discussion, we can classify the given compounds as follows.

a) Solid in bottle a is Ionic as it has high melting point.

b) Solid in bottle b is molecular as it has low melting point.

c) Solid in bottle c is Ionic as it has high melting point.

Label each of the following measurements by the quantity each represents. For instance, a measurement of 10.6kg/m3 represents de

postnew [5]

The quantities represented by each of the measurements are

5.0g/mL - Density

37s - Time

47J - Energy or Work

39.56g - Mass

25.3 cm3 - Volume

325 m/s - Time

500m2 - Area

30.23 mL - Volume

2.7 mg - Mass

0.005L - Volume

To determine the quantity each of the measurements represents, we will observe the units.

5.0g/mL

This represents density. Density is the ratio of mass to volume, and mass is measured in grams (g) while volume is measured in milliliters (mL)

37s

This represents time because time is measured in seconds (s)

47J

This represents Energy or Work because they are measured in Joules (J)

39.56g

This represents mass because mass in measured in grams (g)

25.3 cm3

This represents volume because volume is measured in cubic meters (cm³)

325 m s

This represents time. Time can be measured in milliseconds (ms)

500m2

This represents area because area is measured in square meters (m²)

30.23 mL

This represents volume because volume is measured in milliliters (mL)

2.7 mg

This represents mass because mass could be measured in milligrams (mg)

0.005L

This represents volume because volume is measured in liters (L)

Hence, the quantities represented by each of the measurements are

5.0g/mL - Density

37s - Time

47J - Energy or Work

39.56g - Mass

25.3 cm3 - Volume

325 m s - Time

500m2 - Area

30.23 mL - Volume

2.7 mg - Mass

0.005L - Volume
