The <span>equations that has the correct formulas and also is a balanced equation are:
</span>2Be + O2 - > 2BeO
<span>Mg + O2 - > MgO2
</span>The answer are letters C and D. The rest of teh choices are not balanced chemical equations.
Answer:
The correct answer is option B and D, that is, halogen (chlorine) and hydroxyl.
Explanation:
An artificial sweetener and sugar substitute is sucralose. It is noncaloric as the majority of the sucralose ingested does not get dissociated within the body. The generation of sucralose takes place by the chlorination of sucrose. It is about 300 to 1000 times sweeter in comparison to sucrose.
The consumption of sucralose is safe for both nondiabetics and diabetics, it is used in various food and beverage components due to non-caloric sweetener characteristics. It does not affect the levels of insulin and does not affect dental health. As it is produced by chlorination of sucrose, thus, the functional groups present in it are a halogen (chlorine) and a hydroxyl.
CaO
does not decompose easily.
Explanation:
Calcium oxide is chemically and physically stable at high temperatures.
Maybe you are looking for the decomposition of
CaCO
3
to
CaO
?
That would be
CaCO
3
→
CaO
+
CO
2
Answer:
Explanation:
If we say one mole mole of nitrogen atom it means there is one nitrogen atom present i.e, N. The one mole of nitrogen atom have mass of 14 amu.
If say one mole mole of nitrogen molecule it means there are two atoms of nitrogen present. N₂
One mole of nitrogen molecule have mass of 28 amu.
Atom:
An atom is the smallest particle of an element, which can take part in a chemical reaction.
The atoms of some elements can not exist independently, while the atoms of some elements can exist independently.
Example:
Helium and Neon atoms are exist as He, Ne while atom of hydrogen, nitrogen etc can not exist as H, N.
Molecule:
A molecule is the smaller particle which can exist independently.
It may be monoatomic , diatomic, triatomic etc.
Foe example,
Hydrogen molecule consist of two atoms H₂
Nitrogen molecule = N₂
It may be combination of atoms of different elements.
HCl, H₂SO₄
The overall order of the reaction is 3.
The rate law is rate = k[H₂]¹[NO]².
The <em>overall order</em> is the <em>sum of the exponents</em> of the concentrations.
∴ Overall order = 1 +2 = 3.
The reaction is <em>first</em> order in [H₂], <em>second</em> order in [NO], and third order overall.
