Explanation:

it contains 6.02*1023atoms

Atom, the smallest unit of material which may be separated without releasing electrically charged. It is also the smallest unit of mass with the properties of a chemical element.

          [tex]\to \bold{ 1.75 \times 6.022\times 10^{23}}\\\\\to \bold{ 10.5385 \times 10^{23}}\\\\[/tex]

Therefore, the answer is "[tex]10.5385 \times 10^{23}[/tex]".

Answer:the number of electrons is equal to the number of protons in a neutral atom that is. In a cation or anion atom you either gain or lose electrons. Let’s say it’s a cation +3 you lose 3 electrons. Now let’s say it’s an Anion -3 you gain 3 electrons. Hope this helps.

Answer:

the answer is k? lol thanks

Answer:

K

Explanation:

It is K

Not K+ nor the other options, it is K

Answer:

Ions combine into only one ratio

Explanation:

Just took test

Prefixes are not used to indicate the number of atoms when writing the chemical formula. The number of atoms are written as subscripts to their chemical symbols.

Chemical formula of a compound is used to identify a compound and distinguishes it from other compounds. A chemical formula is written from the chemical symbols of elements which constitute the compound.

The number of atoms of each element is written as the subscripts of the symbols for each atoms. For example,magnesium chloride contains one magnesium and two chlorine atoms thus, its formula is MgCl₂.

The subscripts for each atom in the formula of an ionic compound is the charge of the other  atom into which it is bonded. Similarly, the formula of iron oxide containing 2 Fe and 3 O is written as Fe₂O₃.

Answer:

True

Explanation:

Answer:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O

Explanation:

When a forest burns and all that's left is some ash,  most of the mass of the trees go to the atmosphere, in the form of carbon dioxide.

In a total combustion process of organic matter, the two molecules produced are carbon dioxide and water. (CO₂ and H₂O)

The equation for the combustion of glucose is:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O

Answer:  i think C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O

Answer:

bends and slides under one another

Explanation:

"Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle."

Answer:

Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.) Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust.

See explanation

Explanation:

The ionic radius of metal M decreases as the charge on the metal M increases. The ionic radius is generally defined as the distance between the nucleus and the outermost electron of the ion. Hence, ionic radius becomes much lesser as the magnitude of the positive charge increases.

It is obvious  from the various formulae of metal chlorides in the question that the metal forms cations M^2+, M^3+ and M^4+ respectively. The order of decreasing ionic radius of the compounds is;

MX2 > MX3 > MX4

Answer:

Magnesium nucleus will attract the electrons more toward it and therefore, shrinking the size of the atom. Magnesium atom is smaller than Calcium atom because Calcium has more electron ( 20e− ) which will occupy more energy levels ( n=4 for Calcium versus n=3 for Magnesium)

The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.

Answer:

Oxidizes in air

Explanation:

When water boils, it is still water, just in a different state. solubility and mass are not chemical properties because they don't involve chemical reactions or changing the identity of a substance.

Separate Salt and Water Using Distillation

If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.
