Answer: b. 0.089

Explanation: The <u>Law</u> <u>of</u> <u>Conservation</u> <u>of</u> <u>Mass</u> states that when in a chemical or physical change, the products' mass of a chemical reaction will equal to the mass of the reactants' mass or in other words, mass cannot be created or destroyed.

The same can be said to moles, since, they are also measures of mass.

In the reaction:

CH_{3}CN_{(g)} \rightarrow CH_{3}NC_{(g)}

initially there were 0.200 mol of reactant. After 25 min, there are 0.111 mol left.

This means that 0.089 mol of reactant "transformed" into product.

Therefore, in the reaction vessel, there are 0.089 mol of product.

What is an easy way to measure the volume of an irregular shaped object?
pickupchik [31]

Answer: Water displacement

Explanation:

When you put an irregularly shaped object in a graduated cylinder, the water level rises. Subtract the original number of ml from the number of ml it was displaced, and you get its volume.

A student has four resistors. Each resistor has a resistance of 100 ohms.
ValentinkaMS [17]

Answer:

The minimum resistance is 25 ohms.

Explanation:

Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

Here, all resistors are 100 ohms. So,

\dfrac{1}{R}=\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}\\\\R=25\ \Omega

So, the minimum resistance is 25 ohms.
