Answer: Compounds.
Explanation:
Compounds are formed when an unstable element combines with other elements, they do this by sharing electrons within their outmost shell. Compounds forms when there is a chemical bonding between two or more elements. Examples of compounds includes carbon dioxide (C, O) water (H and O), Sodium chloride (Na, Cl), methane, etc.
Answer:
1- The number of crickets in each container
2- The kind of containers used
Please mark it as brainlest answer:).
Answer:
B
Explanation:
CH4 + O2 →H2O + CO2
Left side
C = 1
H = 4
O = 2
Right side
C = 1
H = 2
O = 3
So find common denominator in this case would be 6 O
CH4 + 3O2 →2H2O + CO2
Left side
C = 1
H = 4
O = 6
Right side
C = 1
H = 4
O = 6
Answer: The formic acid is 3.5 times stronger than acetic acid.
Explanation:
The strength of an acid depends on its acid dissociation constant.
For a hypothetical monoprotic acid HA, the dissociation equilibrium is:
More is the value of , greater is the dissociation and stronger is the acid.
Thus formic acid is 3.5 times stronger than acetic acid.
Answer:
Direct coupling
Explanation:
Direct coupling is sensitive to changes that occurs in temperature. It is electrical energy transfer using physical contact through a medium that is conductive.
It is useful in the interconnection of 2 circuits. This kind of coupling method can be done by a wire, a resistor or through mettalic bonding.
