Answer:
Rate = K[NH₄⁺][NO₂⁻]
Explanation:
In kinetics studies of reaction, rate law is a mathematical expression that relates speed of reaction with concentrations of the reactants. For a reaction:
aA + nN → cC + dD
The rate law is expressed in terms of [A] and [B] as follows:
Rate = K[A]ᵃ[N]ⁿ
<em>Where K is rate constant.</em>
<em />
For the reaction:
NH4+ + NO2– ⟶ N2 + 2H2O
The rate law is:
<h3>Rate = K[NH₄⁺][NO₂⁻]</h3><h3 />
<em>As was said in the problem, the rate is porportional to [NH₄⁺] and to [NO₂⁻]</em>
His work foreshadowed the periodic table. He tried organizing elements into triads, a set of 3 elements with similar properties. In each triad the mean of the lightest and heaviest atomic weight equaled to approximately the atomic weight of the middle element.
Answer:
Metes and bounds
Explanation:
Metes and bounds -
It refers to the process used to define any land or property , is referred to as metes and bounds .
In this method it includes , torrens , lot and block , rectangular .
The factors like direction and distance depending on the rocks or trees , is used in this method .
Hence , from the given information of the question ,
The correct term is metes and bounds .
Answer:
1. atomic #
2.The sugar-water is a homogeneous mixture
Explanation:
1. However, if it has positive ion, then this electron number will go down (ie +2 charge means two electrons have been lost, so the electron/atomic number will go down by two) and vice versa.
2.Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.
Answer:
At constant Pressure V /T = constant. sooooo
49 / 79 = 24.5 / T
T = 24.5 × 79/49 = 39.5°C
