I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
Answer:
A compound
Explanation:
A compound is chemical entity that is formed when 2 or more elements are joined together in a fixed ratio.
This fixed ratio is simply the numerical values of the numbers of these elements. Take for example in the case of water, one atom of oxygen joins together with two atoms of hydrogen. The fixed ratio here is 1 to 2 or 2 to 1 depending on the reference element.
For example also in methane. The molecular formula of Methane is CH4. The ratio between carbon and hydrogen is 1 to 4 here
<u>Answer:</u> The rate law expression is and value of 'k' is
<u>Explanation:</u>
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
For the given chemical equation:
Rate law expression for the reaction:
where,
a = order with respect to nitrogen monoxide
b = order with respect to oxygen
- <u>Expression for rate law for first observation:</u>
....(1)
- <u>Expression for rate law for second observation:</u>
....(2)
- <u>Expression for rate law for third observation:</u>
....(3)
Dividing 1 from 2, we get:
Dividing 1 from 3, we get:
Thus, the rate law becomes:
Now, calculating the value of 'k' by using any expression.
Putting values in equation 1, we get:
Hence, the rate law expression is and value of 'k' is
Answer:
Provide the bond type, molecular structure and intermolecular forces for NaCI, H2O and CO2. Using that information, explain why each of these are in a different phase at room temperature.
Explanation:
Answer:
Density rectangular block = 7.47 (Approx) gm/cm³
Explanation:
Given:
Length = 8.335 cm
Width = 1.02 cm
Height = 0.982 cm
Mass = 62.3538 gm
Find:
Density rectangular block
Computation:
Volume of block = lbh
Volume of block = (8.335)(1.02)(0.982)
Volume of block = 8.3486 cm³
Density = Mass / Volume
Density rectangular block = 62.3538 / 8.3486
Density rectangular block = 7.47 (Approx) gm/cm³
