Two iron rods are placed horizontally, touching end-to-end. One end of one rod is heated. After some time, the other rod also fe
Genrish500 [490]

Answer:

Electrons conducted heat

Explanation:

Iron is a metallic compound. One property of metallic compounds are that they have many loose electrons.

Consider the two rods to be a singular rod, since they touch:

An uncountable number of electrons at one end of the rod are heated, so they gain kinetic energy. Those electrons then collide with other electrons, which energize those as well (although less), which is equal to adding heat. This is a pattern that will flow all the way through the rod.

As part of your job you are asked to make 1 liter of a 0.5 molar sucrose solution. how much sucrose (c12h22o11) do you need? use
kakasveta [241]

Answer:-  171 g

Solution:- It asks to calculate the grams of sucrose required to make 1 L of 0.5 Molar solution of it.

We know that molarity is moles of solute per liter of solution.

If molarity and volume is given then, moles of solute is molarity times volume in liters.

moles of solute = molarity* liters of solution

moles of solute = 0.5*1 = 0.5 moles

To convert the moles to grams we multiply the moles by molar mass.

Molar mass of sucrose = 12(12) + 22(1) + 11(16)  

= 144 + 22 + 176

= 342 grams per mol

grams of sucrose required = moles * molar mass

grams of sucrose required = 0.5*342  = 171 g

So, 171 g of sucrose are required to make 1 L of 0.5 molar solution.

How many moles of gold are there in 14.2×1023 atoms of gold?
timofeeve [1]

Answer : The correct answer is 2.36 mol of gold

1 mole of any element have 6.022 x 10²³ number of atoms ( Avogadro's number).

So the formula relating mole and number of atoms is given as :

Mole = \frac{given number of atom }{ 6.022 * 10^2^3 atom}    * 1 mol

Plugging value in formula :

Mole = \frac{14.2 *10^2^3 }{6.022 x10^2^3}   * 1 mol

Mole of gold = 2.36 mol
