Explanation:

<u>First find the mass of 1 mole of water (Molecular mass)</u>

H_{2} O = 2H + O

= 2(1) + 32

= 34 \: grams

Hence 1 mole of water is 34 g

<u>C</u><u>o</u><u>m</u><u>p</u><u>a</u><u>r</u><u>e</u>

1 mole = 34 g

1.33 mole = x g

\frac{x}{34} = \frac{1.33}{1}

x = 1.33 \times 34

\color{blue}{\boxed{x = 45.2}} \: \: \: \: to \: 3 \: s.f.

Therefore 1.33 moles of water is 45.2 grams

Consider the reaction.
Alex_Xolod [135]

Note the signs of equilibrium:-

  • Reaction don't procede forward or backward
  • Concentration of products and reactants remains same .

So

if

Concentration of A is 2M then concentration of B should be same .

So equilibrium constant K is 1

\\ \rm\rightarrowtail K=\dfrac{[Products]^a}{[Reactants]^b}

So

  • [B]=[A]^2
  • [B]=2^2
  • [B]=4M

A glow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produ
mina [271]

A glow stick will glow longer at lower temperatures than at room temperature, one can infer from the observation. Temperature and reaction time are the test variables.

We notice in this reaction that a glow stick stored in the freezer lights for a longer period of time than a glow stick stored at normal temperature. This implies that temperature affects how long a response lasts.

The most straightforward explanation for this observation is that glow sticks glow longer in colder temperatures than they do at room temperature; as a result, glow sticks kept in the freezer are observed to glow longer than glow sticks kept at room temperature.
