Answer:

A. your reaction makes more products.

Explanation:

This is a fun question dealing with idea of Le Chatelier's principle.

In an exothermic reaction, you produce heat. This means that heat will act as a product (or be on the product side).

Suppose there's an imaginary equation:

A + B -----> C (Now if I lower the amount of B, the equilibrium will shift to left to make up the lost B, or to bring the system back to equilibrium)

Apply the same concept as above below:

A + B -------> C + Heat (as I mentioned, since this is exothermic reaction heat is written as product, so if you lower the temperature, which means basically lower the heat, the reaction will shift towards right to make up the lost heat, in this process you will make extra C which is products. Thus, your reaction makes more products.

1) How many moles are in 4.0x10^24 atoms?
-Dominant- [34]

Answer:

<h2>6.64 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{4 \times  {10}^{24} }{6.02 \times  {10}^{23} }   \\  = 6.644518...

We have the final answer as

<h3>6.64 moles</h3>

Which of the following liquids would have the highest viscosity at room temperature?
Liono4ka [1.6K]

Answer:

5)HOCH2CH2OH

Explanation:

This is also known as ethylene glycol. An increase in hydrogen bonds of a compound means an increase in the viscosity. Hydrogen bonds occur as a result of bonding with electronegative elements such as Oxygen, Nitrogen etc.

The compounds with the highest amount of Hydrogen bond represents the one with the highest viscosity which is B) HOCH2CH2OH

A sample of gold has a mass of 15.7 g and displaces 0.81 cm3 of eater in a graduated cylinder. What is the density of gold?
Ostrovityanka [42]

Answer: 19.4 g/cm3

Explanation: density is the relationship between mass over volume.

So density of gold is 15.7g/0.81cm3 = 19.4 g/cm3

Velocity is the slope of the acceleration vs. time graph.<br>O<br>A. True<br>False​
Maurinko [17]

Answer:

False

Explanation:

The slope of a velocity-time graph gives acceleration. Acceleration can be defined as the change in velocity with time.

A slope denotes the gradient of line. It takes into consideration the changes on both y and x axis. The ratio of the changes gives the slope.

On a velocity-time graph, the y-axis is the velocity and the x-axis is time. The change in velocity with time gives acceleration.

The slope of an acceleration

-time graph is not velocity.
