5) How could you get clean sand from a mixture of sand and little bits of
iron wire?

Answers

Crest a filter from the iron wire and pour the mixture down. The clean sand will go through while the parts that are too large (dirty) sand will not pass through the filter

Depending on the size of iron bits vs. sand granulated.

Use a magnet to attract the ferrous iron particles out of the sand. Depending on scale needed could use an electromagnet.

THE ELEMENTS TEND TO FORM COMPOUNDS BECAUSE AOMS ARE UNSTABLE AND CAN SHARE ELECTRONS IN THIER OUTER ENERGY LEVELS .

AS WE KNOW, ATOMS OF AN ELEMENT BECOMES MORE STABLE BY LOSING , GAINING AND SHARING ELECTRONS.

Elements react with each other to complete their octet or duplet so as to become stavle in nature. For e.g. Carbon reacts with oxygen to form carbon dioxide. Carbon reacts with four molecules of hydrogen to form methane - CH4.

how many molecules are in 2NaOH

Answers

Answer:

1 moles

I assume you are converting between moles 2NaOH and gram. You can view more details on each measurement unit: molecular weight of 2NaOH or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles 2NaOH, or 41.99711 grams.

Explanation:

I hope this helps and pls mark me brainliest :)

Number of molecules are in 2NaOH are 12.044 × 10²³.

What is mole concept?

Avogadro's number is the number of units in one mole of any substance and equals to 6.02214076 × 10²³. The units can be electrons, atoms, ions, or molecules.

No. of moles is defined as a particular no. of particles that we can calculate with the help of Avogadro’s number.

Mass of a particular product is also find out by stoichiometry of a reaction as per the no. of mole given in the reaction.

Given are 2 moles of NaOH.

one mole of any substance and equals to 6.02214076 × 10²³

Therefore, Number of molecules are in 2NaOH are 12.044 × 10²³.

If 1 g of radium-226 has an activity of 1 curie, what is the activity of 2 g of radium-226? 1 curie 2 curies 4 curies 10 curies

Answers

Answer:

2 curies

Explanation:

This is actually pretty easy to explain.

The Radium-226 which is an isotope of the radium, have an activity of curie. This is basically used in radioactivity of certain elements.

As in both cases we have Radium -226 and we are only varying the mass of the Radium, then, we can just do a rule of 3 to calculate this:

1 g Ra-226 --------> 1 Curie

2 g Ra-226 --------> X Curie

Solving for X:

X = 2 g * 1 Curie / 1 g

X = 2 Curies.

You can also see this by taking 2 grams of Ra per separate. On one side you have 1 g of Ra-226 and on the other side, you have another 1 g of Ra-226. Both have 1 Cury of activity. If you put both on the same side, you will have 1 Cury of 1 isotope plus 1 cury of the other isotope, final result? 2 curies.

Hope this helps

The specific heat of water is 4.2j/g ºC how much heat is required to raise the temperature of 100 g of water by 5 ºC

Answers

Answer:

116,823 J

Explanation:

formula : q=m C delta T

q = heat = unknown

mass = 100 g

C = specific heat = 4.2 J/K*g

delta T = temperture in Kelvins: 5 + 273.15 = 278.15 K

q = (100 g) ( 4.2 J/K*g) (278.15 K) = 116,823 J

Be(NO2)2 +

Answers

Answer:

Double Displacement (Metathesis)

Beryllium Chloride - BeCl2

Manganese(II) Chloride - MnCl2

Explanation:

Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below

Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide

To enter an electron into a chemical equation use {-} or e

To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.

Example: Fe{3+} + I{-} = Fe{2+} + I2

Substitute immutable groups in chemical compounds to avoid ambiguity.

For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,

but PhC2H5 + O2 = PhOH + CO2 + H2O will

Compound states [like (s) (aq) or (g)] are not required.

If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.

Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents.

The balanced equation for the given reaction is:

[tex]\rm Mn(NO_2)_2 + 2BeCl_2 \rightarrow 2Be(NO_2)_2 + MnCl_2[/tex]

In chemistry, a balanced equation is a representation of a chemical reaction that follows the law of mass conservation. It assures that on both sides of the equation, the total number of atoms of each element remains constant.
