What is the common device used for measuring heat transfer for chemical reactions called? thermometer
calorimeter
molameter

Answers

Answer 1
Answer:

Answer: Option (c) is the correct answer.

Explanation:

A device with the help of which energy produced or absorbed or specific heat of a chemical reaction is measured is known as calorimeter.

Whereas a thermometer is used to measure the temperature of human body.

For example, when a person is having fewer then thermometer is used to check the temperature of his body.

On the other hand, a molemeter is used to measure the frequency and output voltage for an alternate current source.

Thus, we can conclude that the common device used for measuring heat transfer for chemical reactions called calorimeter.

Calculate the numbers of mL in 0.603 L

Answers

The number of ml in 0.603 l is 603.

What are liter and milliliter?

Liter and milliliter are two measuring units that measure the volume of a liquid. The liter is used to measure large amounts of liquid. And ml is used for measuring a very less amount of liquid.

Measuring units are units that I used to measure the magnitude, amount, or quantity of any object. There are 7 basic measuring units that are used in worldwide and everyday life.

These measuring units are meter that is used to measure the distance, Second, that is used to measure

  • Length - Meter (m)
  • Mass - Kilogram (kg)
  • Capacity - Litre (L)
  • Electric Current - Ampere (A)
  • Amount of Substance - Mole (mol)
  • Luminous Intensity - Candela (cd)
  • Temperature - Kelvin (K)

one liter = 1000 milliliter

0.603 l  = 603 ml.

Thus, the number of ml in 0.603 l is 603.

Answer:

603 mL

Explanation:

A milliliter is a unit of volume equal to 1/1000th of a liter. It is the same as a cubic centimeter.

Write the proper word equation to express the following chemical reaction: 4Fe (s) + 3Sn(NO3)4 (aq) Imported Asset 4Fe(NO3)3 (aq) + 3Sn

Answers

The proper word equation  for

 4Fe + 3Sn(NO3)4  = 4Fe(NO3)3 + 3Sn  is as below

Iron + Tin (iv) nitrate =  iron(iii) nitrate + Tin

  iron displaces  tin from it compound ( Tin (iv) nitrate to form iron (iii) nitrate and tin.

from the equation above 4 moles of Fe  displaces  3 moles of Sn(NO3)4 to form 4 moles of Fe(NO3)3 and  3 moles of SN

A sample that contains 4.78 mol of a gas at 251 K has a pressure of 1.19 atm. What is the volume? Answer in units of L.

Answers

Answer:
            V  =  81.86 L

Solution:

Data Given;
                   P  =  1.19 atm

                   n  =  4.78 mol

                   T  =  251 K

Let suppose the gas is acting ideally, then according to Ideal Gas Equation,

                                         P V  =  n R T

Solving for V,
                                         V  =  n R T / P

Putting Values,
                             
             V  =  (4.78 mol × 0.0812 L.atm.mol⁻¹.K⁻¹ × 251 K) ÷ 1.19 atm

             V  =  81.86 L

Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. Include the following somewhere in your concept map: • types of energy transferred
• medium required (if applicable) for transfer of energy
• speed of energy transfer through various mediums (solid, liquid, gas)
mechanical waves transfer light energy can pass through matter

Answers

Mechanical waves

• types of energy transferred - mechanical energy

• medium required (if applicable) for transfer of energy - yes, mechanical waves require a transfer medium

• speed of energy transfer through various mediums (solid, liquid, gas) - speeds vary for mechanical waves through different mediums


Electromagnetic waves

• types of energy transferred - electromagnetic energy

• medium required (if applicable) for transfer of energy - no medium required

• speed of energy transfer through various mediums (solid, liquid, gas) - transfer speed varies for electromagnetic waves through different mediums

To create a concept map for waves, you need to mention the different types of waves. Mechanical and EM waves are two examples. Mechanical waves
transfer mechanical energy and require a medium. EM waves transfer EM energy
but do not require a medium – they can pass through a vacuum.  Both types of waves have different speeds
transferring through different mediums. Other things that may be mentioned in the map include law of
reflection, idea of diffraction, standing waves and so on.

If a solid contains some particles that melt at 50°C and other particles that melt at 110°C, what must be true about the solid?

Answers

If a solid contains some particles that melt at 50 degrees Celsius and other particles that melt at 110 degrees Celcius, the solid's actual melting point temperature must be near the higher melting point for the solid to be fully melted. It might start to melt at 50 - 110 degrees.
