Magnetism is believed to be caused by the alignment of small, numerous sub-units called _____. poles fields ions domains

Answers

Answer 1

Answer: Magnetism is believed to be caused by the alignment of small, numerous sub-units called domains. A magnetic domain is a small portion in the magnetic fields of atoms that have grouped together and aligned uniformly. To best describe domains, they are often likened to tiny random magnets pointing at different directions within a material. When the material is magnetized, these tiny magnets align and point towards a unified direction.

Answer 2

Answer:

the answer is domains.................

The chemical equation below shows the photosynthesis reaction. 6CO2 + 6H2O mc010-1.jpg C6H12O6 + 6O2 The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO2. How many moles of water are used in this reaction?

Answers

Answer:

12 mol of water

Explanation:

$6CO_2 + 6H_2O \longrightarrow C_6H_(12)O_6 + 6O_2$

First we must find the moles of CO2.

We know that 1 mole of co2 has a mass of 4.01 g so how many moles will there be in 528 g.

We apply a simple rule of three

$44.01 g CO_2\longrightarrow 1 mol CO_2\n 528 g CO_2\longrightarrow x\nx= 528/44.01\nx=12 molCO_2$

By stoichiometry we know that for every 6 moles of carbon dioxide 6 moles of water are needed, now if we have 12 moles of carbon dioxide how many moles of water will be needed

We apply a simple rule of three

$6 molCO_2 \longrightarrow 6 mol H_2O\n 12 mol CO_2 \longrightarrow x\nx= ((12).(6))/(6)\n x= 12 mol H_2O$

Given:
6CO2 + 6H2O -> C6H12O6 + 6O2
molar mass of carbon dioxide (CO2) is 44.01 g/mol
molar mass of water (H2O) is 18.01 g/mol
528 g of CO2

Required:
moles of water

Solution:

528 g of CO2/ (44.01 g/mol CO2) = 12 moles CO2

12 moles CO2 (6 moles H2O/ 6 moles CO2) = 12 moles H2O

12 moles H2O (18.01 g/mol H2O) = 216.12 grams H2O

I think the answer is false. A chain reaction is not strictly for nuclear reactions only. It can be to other types of chemical reaction. As long as, it follows the three main steps which are initiation, propagation and termination.

What is the best way to compare a concentrated solution to a dilute solution, given the same volume of solution?The concentrated solution has less solute than the dilute solution.
a) The concentrated solution has the same amount of solute as the dilute solution.
b) The concentrated solution has more solute than the dilute solution.
c) The concentrated solution has a different amount of solute than the dilute solution.
d) The concentrated solution has the same amount of solute as the dilute solution.

Answers

The correct answer is B. Given a same volume of a solution, the concentrated solution has more solute than the dilute solution. For instance, we are given two NaOH solutions having a volume of 1L one has a concentration of 1M and the other is 2M. The latter has more solute since it has 2 moles of NaOH while the other only has 1 mole.

Answer: b) The concentrated solution has more solute than the dilute solution.

Explanation:-

Binary Solution is a homogeneous mixture of two components called as solute and solvent. Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

Concentrated solution is one in which there is more amount of solid.

Dilute solution is one in which there is more amount of liquid.

Which solution when mixed with a drop of bromthymol blue will cause the indicator to change from blue to yellow 1) 0.1 M HCl. 2) 0.1 M CH3OH. 3) 0.1 M NH3. 4) 0.1 M NaOH

Answers

The solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is A. 0.1 M HCl.

What is an indicator?

An indicator simply means a substance that has measurable and observable characteristics that is important to depict an acidic or alkaline substance.

In this case, the solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is 0.1 M HCl.
