Answer:

Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.

Explanation:

If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.

Which scenario would adhere to the law of conservation of energy?

Nina [5.8K]

Examples of scenarios that would adhere to the law of conservation of energy are as follows:

In a loudspeaker, electrical energy is converted into sound energy.
In a microphone, sound energy is converted into electrical energy.
In a generator, mechanical energy is converted into electrical energy

<h3>What is law is conservation of energy?</h3>

The law of conservation of energy states that energy cannot be created nor destroyed but is conserved when it is transferred from one form to another.

The law of conservation of energy is obeyed by majority of natural and artificial systems. For example;

In a loudspeaker, electrical energy is converted into sound energy.
In a microphone, sound energy is converted into electrical energy.
In a generator, mechanical energy is converted into electrical energy

Calculate the molarity of each of the following solutions.

Charra [1.4K]

Answer:

a)1.56 M

b) 0.376 M

c) 0.599 M

Explanation:

Step 1: Molarity

Molarity = Number of moles / volume in L

Number of moles = mass / Molar mass

(a) 7.49 g of methanol (CH3OH) in 1.50 * 10² mL of solution

Volume = 1.50 * 10² mL = 0.15 L

Molar mass of CH3OH = 32.04 g/mol

Number of moles CH3OH = 7.49 grams / 32.04 g/mol

Moles of CH3OH = 0.234 moles

Molarity CH3OH = 0.234 moles / 0.15 L

Molarity CH3OH = 1.56 M

(b) 9.18 g of calcium chloride (CaCl2) in 2.20 × 10² mL of solution:

Volume = 2.20 × 10² mL = 0.22L

Molar mass of CaCl2 = 110.98 g/mol

Number of moles CaCl2 = 9.18 grams /110.98 g/mol

Moles CaCl2 = 0.0827 moles

Molarity CaCl2 = 0.0827 moles / 0.22L

Molarity CaCl2 = 0.376 M

Volume = 85.2 mL = 0.0852L

Molar mass of C10H8 = 128.17 g/mol

Number of moles C10H8 = 6.51 grams / 128.17 g/mol

Moles C10H8 = 0.051 moles

Molarity C10H8 = 0.051 moles / 0.0852 L

Molarity C10H8 = 0.599 M

________ are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds

olga_2 [115]

<u>Hydrogen bonds </u>are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.

The hydrogen bond is weak bond.

The hydrogen bond is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
The hydrogen bond is occur in polar , contently bond atoms in different molecules.
Example is H-O-H or $NH_{3}$
The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.
