Pizza - M
Dry Ice - C
Baking Soda - C
Explanation:
An element is the smallest part of a substance that is capable of independent existence. An element cannot be broken down into any other substance. Krypton, Bismuth etc are all elements.
A compound is a combination of two or more elements which are chemically combined together e.g NH3, CO2 etc.
A mixture is any combination of substances that are not chemically combined together. E.g Pizza, milk etc
E=hv
h = 6.626 × 10^-34 joule·s
v=frequency
i got 4.7636x10^-30 J
It is true that metallic bonds are responsible for many properties of metals such as conductivity.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
Metallic bond increace electrical and thermal conductivity.

Answer: The density of the object is 1.10 g/ml
Explanation: Density of object = ?
Mass of object = 26.5 g
Volume of object = volume of water displaced = 24.1 ml
Putting values in above equation, we get:
Thus density of the object is 1.10 g/ml
Answer:
Both are right
Explanation:
A constant heat must be supplied for several minutes to soldering gun to overcome the melting point of solder. A butane torch is a type of soldering device powered (energised) by the burning of butane gas to melt and solder common metals
