3 0

The sulfuric acid can be constituted into different concentrations using distilled water as a diluent.

<h3>What is dilution of acid?</h3>

Dilution of acid is defined as the decrease in the concentration of an acid using water.

For sulfuric acid to be diluted, it is slowly added to distilled water using the following guidelines:

  • Add 150 ml of water to the beaker and add the desired amount of acid. This will give a diluted concentration of the given acid.

Which is true for every atom of an element?
antoniya [11.8K]

C. It has mass and volume

Explanation:

Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.

The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.

Atoms also have specific volume.

  • The reason for our selection is that atoms are the smallest particle of matter.
  • Matter is anything that has weight and occupies space.
  • Since it is matter, it must have specific weight and volume

15. In the image given below, magnesium metal is coiled as a thin ribbon. What property of metal is exhibited by it? A Ductility
Sholpan [36]

Answer: The property of magnesium that is exhibited by it is DUCTILITY. The correct option is A.

Explanation:

Magnesium is a member of the alkaline earth metals. It occurs in nature, only in the combined state, as Epsom salt, dolomite and in many trioxosilicates( IV) including talc and asbestos. They have the following physical properties:

--> Appearance: they are silvery-white solids

--> Relative density: It has a relative density of 1.74

--> DUCTILITY: it's very ductile in nature

--> melting point: it has a melting point of 660°C.

--> Conductivity: They are good conductor of heat and electricity.

Furthermore, DUCTILITY is the physical property of a metal associated with the ability to be hammered thin or stretched into wire without breaking. A metal such as magnesium can therefore be coiled as a thin ribbon without fracturing due to its ductile physical properties.

4. If an experimental value for a given observation was 415 nm while the theoretical value
Alex

Answer: % error of observation is 4.77%

Explanation:

Given:

Observation value = 415nm

theoretical value= 435.8nm

Percent error of observation = theoretical value- observation value/ theoretical value x 100 %

= 435.8-415/435.8= 0.04772 x 100 = 4.77%

therefore % error of observation is 4.77%
