At room temperature, all samples of liquid water must have the same

Chemistry

The answer is 2. density

At room temperature, all samples of liquid water must have the same density.

Whatever the volume of different liquid water samples, they always have same density. As density of liquid water is always same that is 1 g cm⁻³. So different liquid water can have different volume, weight and mass but their density always remains same.

A student collected a total of 36.04 g of water from a reaction. What number of moles of water does this represent
umka21 [38]
To find the number of moles from a mass given, simply look to the formula n (moles) = m (mass, g) / MM (molar mass).
Mass was given, 36.04
Molar mass is the total atomic mass of all the atoms present. Water is H20, so that means 2 hydrogen and 1 oxygen. The atomic mass of hydrogen is 1 and atomic mass of oxygen is 16. Therefore MM= 1 + 1 + 16= 18.
Plug that value in and the full equation is
n = 36.04/18
n = 2.002 moles
= 2 moles

must undergo addition because they have easily broken π bonds. ____________ rule states in the addition of HX to an unsymmetrica
erastova [34]

Answer:

Alkenes, Markovnikov's, Alkenes, Alkyl halides, and less.

Explanation:

Alkenes must undergo addition because they have easily broken π bonds.

Markovnikov's rule states in the addition of HX to an unsymmetrical alkene, the H atom bonds to the less substituted carbon atom.

Alkenes are unsaturated hydrocarbons because they have fewer than the maximum number of hydrogen atoms per carbon.

Alkyl halides have good leaving groups and therefore readily undergo substitution and elimination reactions.

In hydroboration, the boron atom bonds to the less substituted carbon.

What is the law of reciprocal proportion​
irina [24]

If two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine with each other.

PLS ANSWER FAST AHAH<br><br> distilled water is a pure substance <br> true or false ?
mr Goodwill [35]

Answer:

True

Explanation:

If you see distilled water, it's a pure substance. That means that there are only water molecules in the liquid. A mixture would be a glass of water with other things dissolved inside, like one of those powders you take if you get sick or Kool-Aid.
