The temperature change of a 36-gram sample of water is <u>4.61 K</u>

Temperature is the degree of the average kinetic energy of the debris in an item. while the temperature will increase, the movement of this debris additionally will increase. Temperature is measured with a thermometer or a calorimeter.

heat = msΔt

     695 Joule = 36 ×  4.186 × Δt

Δt   =  695/ 36 ×  4.186

      = <u>4.61 K</u>

Temperature is just a dimension that indicates the common kinetic energy of 1 atom or molecule. as a result, when we are saying something is warm or bloodless, we're generally using any other reference point to define the hotness and coldness of a frame.

How many grams of NaOH are required to neutralize 700 mL of 3.0 M HCl?
sveta [45]

A gram of NaOH required to neutralize 700 ml HCL is <u>84 grams.</u>

Neutralization or neutralization is a chemical response in which an acid and a base react quantitatively with each different. I

Moles of solute = Molarity × Liters of solution

                           = 3 × 0.7 L

                          = 2.1 mole

The molar mass of NaOH = 40

mass of NaOH = 40 × 2.1 g

                        =<u> 84 gram.</u>

A neutralization response may be described as a chemical reaction in which an acid and base quantitatively react together to shape salt and water as products. In a neutralization response, there's a combination of H+ ions and OH– ions that form water.

A neutralization response is when an acid and a base react to shape water and salt and includes the mixture of H+ ions and OH- ions to generate water. The neutralization of a sturdy acid and robust base has a pH equal to 7.

why does nitrogens lewis structure have 5 dots around it while nitrogens Bohr diagram has seven dots around it?
leonid [27]

Answer:

Bohr diagram shows electrons orbiting the nucleus. Nitrogen has 7 electrons orbiting the nucleus

Lewis structure is the simplified Bohr diagram. It only shows the electrons in the outer shell. For Nitrogen, 2 electrons are in the first shell. The remaining 5 electrons are in the outer shell.
