Need Chemistry help ASAP! Which of the following statements regarding chemical equilibrium is NOT necessarily true? A.) Equilibrium is shown using a double arrow.
B.) When a system is at equilibrium, it continues to react both ways (forward and reverse).
C.) At equilibrium, the amounts of reactants equal the amounts of products. D.) At equilibrium, particle-level changes are occurring.

Need an answer as soon as possible! Thanks so much!

Answers

C is necessarily not true because at equilibrium, only the rates of the forward and reverse reaction are the same. Concentrations and amounts of both reactants and products do not have to be the same at equilibrium

NaOH + HCl → NaCl + H2O. What mass of water forms when 2.75 × 10–4 mol NaOH reacts completely? given the equation, 2.75 × 10–4 mol NaOH = ___ g H2O

Answers

The balanced chemical reaction is written as:

NaOH + HCl → NaCl + H2O

We are given the amount of sodium hydroxide to be used up in the reaction. This will be the starting point for the calculation.

2.75 x 10^-4 mol NaOH ( 1 mol H2O / 1 mol NaOH ) ( 18.02 g H2O / 1 mol H2O ) = 4.96 x 10^-3 g H2O

How can I get the 3 sig figs of this number 187515.4207

Answers

Answer:

1.88 x 10^5

Explanation:

You have to round because all of the numbers in 187515.4207 are significant

Round to: 188000

Put in scientific notation:

1.88 x 10^5

Answer:

well scientific notation would be = 1.875154207 × 10^5

you cant rlly simply the number any further to get 3 sig figs

youd need something like 187 to be 3 sig figs

are you saying the question correctly?

Solve for y. -3/y+6=2

Answers

Answer: -7.5

Explanation: To solve for y in the equation -3/(y + 6) = 2, you can follow these steps:

First, we want to get rid of the fraction. To do that, multiply both sides of the equation by (y + 6) to cancel out the denominator:

-3/(y + 6) * (y + 6) = 2 * (y + 6)

This simplifies to:

-3 = 2(y + 6)

Now, distribute 2 on the right side of the equation:

-3 = 2y + 12

Next, isolate the term with 'y' by subtracting 12 from both sides of the equation:

-3 - 12 = 2y

-15 = 2y

Finally, divide both sides by 2 to solve for 'y':

-15/2 = y

So, the solution for y is:

y = -15/2

You can also express this as a mixed number:

y = -7.5

Which of the following is not true of alloys?a. Alloys are made of two or more metals combined physically.
b. The mixture of metals in an alloy is based upon the desired use.
c. Alloys can be substitutional or interstitial.
d. An example of an alloy is copper.
