Answer : K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
Explanation :
The relation between the equilibrium constant and standard Gibbs, free energy is:
where,
= standard Gibbs, free energy
R = gas constant
T = temperature
K = equilibrium constant
From the above relation we conclude that,
When K > 1 then the value of is negative.
When K < 1 then the value of is positive.
When K = 1 then the value of is zero.
When K = 0 then the value of is undefined.
Hence, K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
Chelation. Dimercaprol and dimercaptosuccinic acid are chelating agents that sequester the arsenic away from blood proteins and are used in treating acute arsenic poisoning. The most important side effect is hypertension. Dimercaprol is considerably more toxic than succimer.
The atomic mass of rubidium listed in the periodic table to determine the mass of Rb−87 is 86.13 amu.
<h3>What is atomic mass?</h3>
The atomic mass is the weight of the roton neutron and electron present inside the nucleus and shells of an atom and the elements are arranged on the basis of this only.
The mass of Rb−85 is 84.9118 amu for 1 amu it will be
amu = 84.9118 / 85 = 0.99
so, the amu for Rb−87 will be,
AMU = 87 × 0.99 = 86.13 amu.
Therefore, the mass of Rb−87 is 86.13 amu for atomic mass of rubidium listed in the periodic table.

Answer:True.
As you increase the wavelength the frequency decreases.
Explanation:
The wavelength of a wave is the distance(in meters) between the two consecutive crest and trough of a wave. The S.I unit of the wavelength is meter.
The frequency of a wave is the number of complete wave cycle passing a particular point per second. The S.I unit of the frequency is Hertz.
Wave's frequency and wavelength are related to each other as
Frequency = 1 / Wavelength
As the Frequency is inversely proportional to the wavelength of a wave so as the frequency will increase the wavelength of the wave will decrease and vise-versa.
So, its true that As we increase the wavelength the frequency decreases.
Answer: Combustion
Explanation:
Methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. Therefore there are four products, carbon dioxide, water, carbon, and carbon monoxide.
