Answer: Suspension mixture, colloidal mixture, and solution mixture
Explanation: These are the three types of mixtures, hopefully this helps.
Answer: Option (4) is the correct answer.
Explanation:
Activation energy is the minimum amount of energy required by reactant molecules to undergo a chemical reaction.
Whereas a catalyst is defined as the substance that helps in increasing the rate of reaction by decreasing the activation energy without itself getting consumed in the reaction.
When a catalyst decreases the activation energy then molecules with lesser energy become able to participate in the reaction and thus, products are obtained at a faster rate. Hence, a catalyst increases the rate of a reaction.
Thus, we can conclude that a catalyst works by decreasing the activation energy required for a reaction.
Transverse waves are bigger than longitudinal waves
A transverse wave has crests and troughs and a longitudinal has compressions and rarefactions.
Transverse waves are sound waves and longitudinal waves are light waves.
Answer:
A transverse wave has crests and troughs and a longitudinal has compressions and rarefactions.
catalytic converter
food preservatives
amino acids
Answer:
catalytic converter
Explanation:
A heterogeneous catalyst is one that has a phase different from the reactant molecules. A catalyst speeds up a chemical reaction by lowering the activation energy required to start the reaction. But a catalyst does not undergo any change in the chemical process. Catalysts in a catalytic converter are metallic palladium or platinum that react with the hydrocarbons and carbon monoxide from the exhausts of a car to form carbon dioxide and water.
A heterogeneous catalyst is a catalyst that works in a different phase than the reactants. An example of this is a catalytic converter, used in cars to convert harmful emissions into less harmful substances.
In chemistry, a heterogeneous catalyst is a catalyst that exists in a different phase from the reactants. The primary purpose of a heterogeneous catalyst is to accelerate a certain chemical reaction without being consumed in the process. A clear example of a heterogeneous catalyst is a catalytic converter used in vehicles. The function of a catalytic converter is to convert harmful engine emissions into less harmful substances through catalysed chemical reactions. It includes metals like Platinum, Palladium, and Rhodium, which are what actually does the catalysis.

The balanced chemical equation is CH4 + 4S8 --> CS2 + 4H2S. The moles of CS2 produced from 1.50 mol S8 will be 1.50 mol.
To balance the chemical equation CH4 + S8 --> CS2 + H2S, we'll start by balancing the sulfur atoms. The balanced equation becomes: CH4 + 4S8 --> CS2 + 4H2S. Now, count the carbon and the hydrogen atoms on both sides. These are balanced successfully, and hence the overall equation is balanced.
Now, let us calculate the moles of CS2 produced from 1.50 mol S8. Using stoichiometry, a ratio derived from the balanced equation, we find that 1 mol of S8 produces 1 mol of CS2. So, 1.50 mol S8 will produce 1.50 mol CS2.
