5 A student finds the mass and volume of four mystery liquids. Liquid Mass (9) Volume (mL) W 5 5 х 6 2 Y 2. 1 Z 2 00 No The student knows that the density of water is 1 g/mL. Which of the four mystery liquids can be correctly identified as water? Density = Mass / Volume A w B X

A. W

Explanation:

we know the equation Density = mass/volume ( D = g/mL ).

we know that the density of water is 1 g/mL.

Liquid W = 5g/5 mL = 1 g/mL

Liquid X = 6g/2 mL = 3 g/mL

Liquid Y = 2g/1 mL = 2 g/mL

Liquid Z = 8g/.2 mL = 40 g/mL

A. W because that liquid has the same density as water.

Hope this helps you.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
