Carbon dioxide is a primary effluent gas because it is being generated in large amounts by:
1) The burning of methane which produces water vapor and carbon dioxide
2) The decomposition of limestone, CaCO₃ to CO₂ and CaO
Sulfur is contained within the clay and the high temperature and combustion conditions cause it to form Sulfur dioxide which exits the kiln.
The answer for the following problem is mentioned below.
- <em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Explanation:
Force:
The push or pull on an object with mass that cause change in the velocity
It is a vector quantity.
The formula to calculate the force is:
F = m × a
Given:
Force (F) = -136 N
acceleration (a) = -9.6 m/s^2
To calculate:
mass of the object (m)
We know that,
<em>F = m × a</em>
where,
F represents the force of the object
m represents mass of an object
a is acceleration of an object
From the equation;
-136 = m × -9.6
m =
m = 14.16 grams
<em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Answer:
The correct answer is option B.
Explanation:
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
The equation for the ionization of the magnesium hydroxide is given as:
xS yS
Here, S = concentration of compound dissolved in solvent via dissociation
Expression for the solubility product of will be:
As we can see,
- Higher the value of [S] more will be solubility of compound in a solvent.Hence, more soluble it will be.
- Lower the value of [S] less will be solubility of compound in a solvent.Hence, less soluble it will be.
Hence, the correct answer is option B.
Answer:
no
Explanation:
because it will need more energy to move from 5th to 3rd than 4th to 2nd since it is closer to the nucleus
This is an incomplete question. The complete question is:
Consider the following reaction: 2 C + D → J + 2 K .You are told that the rate of this reaction is second order overall and second order in [C]. Could any of the following be a rate-determining first step in a reaction mechanism that is consistent with the observed rate law for the reaction (note that substance Z is an intermediate)?
Answer choices
C → J + Z
C + C → K + Z
D → J + K
C + D → J + Z
Answer:
C + C → K + Z
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
given x = 2
Over all order = x+ y = 2
Thus y= 0
Thus the rate determining step must use two molecules of C as that determines the order of reaction.
The only choice that fits in is C + C → K + Z
