Answer:

nonmetel

Explanation:

Answer:

Its a non-metal

Explanation:

Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gaseous, liquids or solids.

d. cause it is a part of energy

Answer:

A. a rotten potato gives all of bad smell

Explanation:

B,C,D are all physical changes because we can reverse them back.we can cool the water back to make ice. if the wind passes again we can randomly get the same cloud shape in c. and in d we can make that statue again. but in A can we reverse the rotting process ? ( the enzyme reaction) no we cant because it is a chemical reaction it gives a bad smell because of the chemical changes occuring in it.

Answer:

The anser is c

Roman numerals are used to indicate oxidation states. Hence, option C is correct.

An oxidation state is a number given to the atom of an element when participating in a chemical reaction.

Roman numerals are used to indicate oxidation states of transition metals.

The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.

The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.

[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).

Hence, option C is correct.

Hey there!

Molar mass of O3 = 47.9982 g/mol

therefore:

1 mole O₃ ---------------------  47.9982 g

moles O₃ ---------------------- 24 g

moles O₃ = 24 x 1 /  47.9982

moles O₃ = 24 / 47.9982

moles O₃ = 0.500 moles

Answer:

Group 2 is the correct answer.

Explanation:

Chlorine has a charge -1. It means that X is +2 so that the formula is XCl2.

Answer:

Newton's third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts. Newton's third law is useful for figuring out which forces are external to a system

Ca(OH)₂ is the correct chemical  formula unit of an ionic compound.

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.

There are four types of chemical formula:

1)empirical formula

2) structural formula

3)condensed formula

4)molecular formula

Answer:

2.7g/cm³

Explanation:

Given parameters:

Dimension of the aluminum  = 10.5cm x 10.5cm x 0.1cm

Mass of the aluminum  = 29.8g

Unknown:

Density  = ?

Solution:

Density of a substance is its mass per unit volume;

  Mathematically;

       Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the aluminum  = 10.5cm x 10.5cm x 0.1cm = 11.025cm³

  So, insert the parameters and solve;

  Density  = [tex]\frac{29.8}{11.025}[/tex]   = 2.7g/cm³

Answer:

ΔT = 0.843 °C

Explanation:

Given data:

Heat added = 0.484 J

Mass of water = 0.1372 g

Temperature increase = ΔT = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity of water is 4.184 j/g.°C

Now we will put the values in formula.

0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT

0.484 j = 0.574j/°C× ΔT

ΔT = 0.484 j / 0.574j/°C

ΔT = 0.843 °C
