<span>The another way of exciting the electrons without using a bunsen burner is by using microwave owen as it heats by exciting electrons directly without using a flame.There are several opportunities to excite electrons within an atom or a molecule.The energies to excite a single electron in an atom start at roughly 10-19J, which is approximately the energy of red light.</span>

How much heat is required to change 56.0 g of ice (H2O) at 263 K to vapor (steam) at 400 K?
Leona [35]

Heat required = 173 kJ

<h3>Further explanation</h3>

Given

56.0 g of ice

Temperatur at 263 K(-10 C) to 400 K(127 C)

Required

Heat needed

Solution

1. raise the temperature(-10 C to 0 C)⇒c ice=2.09 J/g C

\tt Q=56\times 2.09\times (0-(-10)=1170.4~J

2. phase change (ice to water)⇒Heat of fusion water=334 J/g

\tt Q=56\times 334=18704~J

3. raise the temperature(0 C to 100 C)⇒c water= 4.18 J/g C

\tt Q=56\times 4.18\times (100-0)=23408~J

4. phase change(water to vapor)⇒heat of vaporization water=2260 J/g

\tt Q=56\times 2260=126560~J

5. raise the temperature(100 C to 127 C)⇒c vapor=2.09 J/g C

\tt Q=56\times 2.09\times (127-100)=3160.08~J

Total heat :

1170.4+18704+23408+126560+3160.08=173,002.48 J=173 kJ

The mass of an iron(II) sulfate crystal is 8.36 g.How many moles of FeSO4 are in the crystal?
Yuki888 [10]

The number of moles present in the FeSO4 are 0.055 mol.

<u>Explanation:</u>

  • The mass of a substance containing the same number  atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to  6.023 x 10^23. The moles of a substance can be determined by using the formula,

                 Number of moles = mass in grams / molecular mass

Given,

    mass = 8.36 g,

    molecular mass of FeSO4 = 151.908 g / mol

         number of moles = 8.36 / 151.908

                                       = 0.055 mol.

What is homogeneous mixture?
Nataly [62]

A mixture is a portion of matter made up of two or more substances called constituents. Mixtures are the product of the mechanical joining of substances without change in chemical nature, and therefore, each constituent retains its properties.

How do H3O+ and OH relate to acids, bases and the pH scale?
Liula [17]

Answer: An acid is defined with having more [H₃O+] ions, and a base is defined with having more [OH-] ions. On the pH scale, an acid has a lower pH and a base has a higher pH. With this being said, the lower the pH, the more [H₃O+] ions are present and the higher the pH, the more [OH-] ions are present.

Explanation:

I hope this helps!! Pls give brainliest!! :)
