Answer : The correct option is, reactants

Explanation :

Chemical equation : In a chemical reaction, when the reactants are combined or separated to form new products.

For example :

6Li+N_2\rightarrow 2Li_3N

This is a chemical reaction in which the 'Li' and N_2 are the reactants and LiN_3 is the product.

In 6Li and 2Li_3N, 6 and 2 are the coefficients.

Therefore, the substances in a chemical reaction that are combined or separated to form new substances are the reactants.

A student sets up the following equation to convert a measurement.
dybincka [34]

Answer:

\frac{1 m}{100 cm}

Explanation:

The final answer has a different set of units. In particular, meters (m) changes to centimeters (cm). To make this change, you need to multiply the first value by proportions.

When writing these proportions, it is important that they are arranged in a way that allows for the cancellation of units. For instance, since m is located in the denominator, it must be located in the numerator of the conversion.

<u>Proportion:</u>

1 m = 100 cm

The full expression:

<h3>-1.7*10^5\frac{V}{m}  ·  \frac{1 m}{100 cm}  =  ? \frac{V}{cm}</h3><h2>                 ^</h2>

As you can see, the old unit (m) cancels out and you are left with cm in the denominator.

Hello!

My argument: Which is better a Ps4 or an Xbox 1


The Ps4 is a better all-round console. The PS4 costs $100 less but has less games than the Xbox 1. The Xbox 1 now came up with dual compatible games. This means that certain games can now run on the Xbox 1 and the Xbox 360. The overall winner is really undetermined. The controller for Xbox has more quicker response time and is specifically built to be an extremely comfortable in your hands. Unlike the PS4 which their controller is built for nothing they really didn't do anything to theirs. Although the console comparisons are the same. The hard drive for the Xbox is non- removable meaning that if you want the hard drive. you would have to break the Xbox to get it . Unlike the Ps4 when you can take it out easily and switch it with any console and still have your data. I am an Xbox fan since for ever but I think that the two consoles are built the same.


Hope it helps!
