Answer:  It always contains certain elements.

It always contains elements in definite proportions.

Explanation:

A mineral is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition

All the minerals are Naturally occurring i.e. they can not be man made. They are inorganic i.e. it can never come from something living. They occur as Solids i.e they have definite shape and volume. They have Crystal structure i.e they are formed by repeating units. They have definite chemical composition i.e they are made up of certain elements and the elements will always be present in a fixed ratio by mass.

<h2>Answer:It always contains certain elements,It always contains elements in definite proportions.,It cannot contain atoms from more than one element.</h2>

Explanation:

The mineral need not occur always in a pure form.On purification we get the exact chemical composition.

The mineral always has a definite chemical composition which means the number of elements and types of elements in the mineral does not change.

Since the mineral has definite composition,the elements in the mineral has definite proportions.

The mineral can be a compound.So,there can be atoms from more than one element.

How many grams of acetylene are produced by adding 3 moles of cac2
jolli1 [7]

Answer:

78.12g of acetylene

Explanation:

Acetylene and calcium hydroxide are produced when H₂O reacts with CaC₂. The reaction is:

2 H₂O + CaC₂ → C₂H₂ + Ca(OH)₂

<em>Where 1 mole of C₂H₂ (acetylene) is produced per mole of CaC₂</em>

Thus, the addition of 3 moles of CaC₂ produces 3 moles of acetylene.

As molecular mass of acetylene is 26.04g/mol, grams of acetylene produced are:

3mol C₂H₂ × (26.04g / mol) = <em>78.12g of acetylene</em>

bazaltina [42]

 The statement  which is true  about  the three sub atomic particles  is

X is  a neutron,Y is a protons and z is an electron

<u><em>Explanation</em></u>

  •  Atom  has three  sub  atomic    particles,that  is  neutrons,protons and electrons.
  • Neutrons have no electric  charge,protons  are positively  charged while electrons  are  negatively  charged.
  • Both  neutrons and proton are located in the nucleus while electrons  are  located outside the  nucleus.
  • since electrons   are located  outside the  nucleus  they  orbit  around the nucleus.
