Hydrogen bond is found between water molecule if im correct
Answer:
Random samples
Explanation:
It needs to be random so that there isn't bias that would skew the consistency
9 grams of hydrogen gas (H2) will SC Johnson need to react in order to make 1 bottle of Windex.
Explanation:
Balance equation for the formation of ammonia from H2 gas.
N2 + 3H2 ⇒ 2 
Given
mass of ammonia in 1 bottle of windex = 51 gram
atomic mass of ammonia 17.01 gram/mole
number of moles = 
number of moles = 
= 3 moles of ammonia is formed.
in 1 bottle of windex there are 3 moles of ammonia 0r 51 grams of ammonia.
From the equation it can be found that:
3 moles of hydrogen reacted to form 2 moles of ammonia
so, x moles of hydrogen will react to form 3 moles of ammonia.
= 
x = 4.5 moles of hydrogen will be required.
to convert moles into gram formula used:
mass = atomic mass x number of moles (atomic mass of H2 is 2grams/mole)
= 2 x 4.5
= 9 grams of hydrogen.
Answer:
The answer is carbon cycle.
Explanation:
The carbon cycle is an important process for living organisms. As plants prepare their food through photosynthesis and is also an important source of fossil fuels for human activities.
Therefore carbon atoms are regenerated again and again in the carbon cycle process. This recycling process takes place between livings and nonliving things in the environment and also within the earth biosphere.
Abundance supply of carbon is necessary to carry out the biological processes. The entire carbon cycle is actually made up of sourced and sinks elements.
Answer:
Explanation:
a ) 2FeCl₃ + 3Li₂S = Fe₂S₃ ( s ) + 6 LiCl
2Fe⁺³ + 6Li ⁻ + 6Cl⁻ + 3S⁻² = 6Li + 6Cl⁻ + Fe₂S₃ ( s )
b )
3CH₃COONa +( NH₄)₃PO₄ = 3CH₃COONH₄ + Na₃PO₄
3CH₃COO + 3Na⁺ + 3NH₄⁻ + PO₄⁺³ = 3CH₃COO⁻ +3NH₄⁺ + Na₃PO₄
c )
HClO₄ + KOH = kClO₄ + H₂O
H ⁺ + ClO₄⁻ + K⁺ + OH⁻ = k⁺ ClO₄⁻ + H₂O
d )
NH₄OH + HNO₃ = NH₄NO₃ + H₂O
NH₄⁺ + OH⁻ + H⁺ + NO₃⁻ = NH₄⁺ + NO₃⁻ + H₂O
e )
HNO₂ + KOH = KNO₂ + H₂O
H⁺ + NO₂⁻ + K⁺ + OH⁻ = K⁺ + NO₂⁻ + H₂O
f ) HIO₃ + CaCO₃ ( s ) = Ca( IO₃ )₂ + H₂CO₃
H⁺ + IO₃⁻ + CaCO₃ ( s ) = Ca( IO₃ )₂ + H₂CO₃
g )
c ) is strong acid and strong base
d ) is weak base and strong acid
e ) weak acid and strong base
f ) Strong acid and basic salt
