what is the answer to this:magnesium+oxygen

Answer:

Anything that occupies space and has mass is matter but the matter that has specific composition and chemical characteristics is substance

Answer:

Substance: Something that has only 1 atom, for example; Water.

Matter: Made up of more than 1 atom, example; Humans

Explanation:

As said a substance is something that has only 1 atom like water or tin.

Matter is well almost everything in the universe, there's a reason some people say; This is Human Matter. I'm pretty sure it's somewhere in the bible too.

Answer:

Pasteurization is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.

Answer:

The nucleus has an overall positive charge as it contains the protons.

Explanation:

Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

Answer:

A) 17.5%

B) 1) 2135 kg

2) 375 kg

C) 91.8

Explanation:

Part (A):

1 tonne= 1000 kg= 100%

Aluminium oxide= 825 kg= 82.5%

Iron (lll) oxide= 100 kg= 10%

Sand= 85 kg= 7.5%

That makes total of 100%

So, the percentage of impurities= Iron (lll) oxide + Sand

=> 10 + 7.5= 17.5%

Part (B):

(1) 1 tonne= 427 kg

Multiplying both sides by 5

=> 5 tonne= 427 * 5

=> 5 tonne = 2135 kg

(2) 1 tonne contains 75 kg sand as impurity

=> 1 tonne= 75 kg

Multiplying both sides by 5

=> 5 tonnes = 75 * 5

=> 5 tonnes = 375 kg

Part (C):

If all of the iron oxide was removed, then only aluminium and sand are left.

Aluminium = 825 kg

Sand= 74 kg

Total of them makes it:

=> 825 + 74 = 899

So,

% age of Aluminium= 825/899 * 100

% age of Aluminium= 0.918 * 100%

% age of Aluminium= 91.8%

The rearrangement produces a more stable tertiary carbocation and the unexpected product.

In the image shown, the substrate is 1-cyclobutylethene. The attack of H2SO4 and water will lead to the conversion of the alkene to an alkanol. Two possible products may be obtained with one being greater than the other.

The unexpected product (Shown in the image attached) is obtained due to rearrangement of the carbocation intermediate. The rearrangement produces a more stable tertiary carbocation and the unexpected product.

Answer:

Relation between AMU and Gram

The mass of an atom in amu is numerically the same as the mass of one mole of atoms of the element in grams. One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g. For compounds, the molecular mass (in amu) is numerically the same as the mass of one mole of the compound in grams.

This problem is asking for the reason behind the nonexistence of elementary substances with ionic bonds. First of all, it is necessary to bear to mind that the definition of the type of bond in a compound depends on the difference electronegativity that is present between two of the atoms composing it.

For instance, in binary salts, such as KCl, NaCl, KBr and so on, we are able to know these are all ionic because they are composed by a metal and a nonmetal, which have the smallest and largest electronegativities, so that the difference electronegativity is large enough to produce an ionic bond.

In contrast, elementary susbtances, such as liquid bromine (Br2) and gases such as H2, N2, Cl2, F2 and O2, since they are all nonmetals and the same type, the electronegativity difference will be 0 and therefore, they will not be ionic but covalent.

Answer:

the balanced equation for the above reaction is as follows;

3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl

stoichiometry of NiCl₂ to K₃PO₄ is 3:2

the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol

according to molar ratio  

if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄

then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄

molarity of given K₃PO₄ solution - 0.205 M

there are 0.205 mol in 1000 mL  

therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL  

volume of K₃PO₄ needed is 4.44 mL

This problem is providing information about the loss of mass for a reaction 50 °C as a function of the time elapse. Thus, when taking a look at the given graph, we can trace a horizontal line on the y-axis at 0.95 g in order to intercept it with the curve, and hence, figure out the time at which that loss of mass takes place.

Thus, we can see that when the loss of mass hits 0.95 g, the corresponding time on the graph is about 80 seconds, and hence, the rate of reaction turns out to be:

[tex]r=\frac{0.95g}{80s}\\\\r=0.012\frac{g}{s}[/tex]

Which has two significant figures as required.
