Consider the following equation.
Natasha2012 [34]

With the increase in temperature, the state of matter of water will changed.

<h3>What happen if the temperature of the system is increased?</h3>

If the temperature of water is increased then the state of matter will change from liquid state to gaseous state because the temperature break down the bonds that is present between two water molecules.

So we can conclude that with the increase in temperature, the state of matter of water will changed.

The rate of disappearance of HBr in the gas phase reaction 2HBr(g)→H2(g)+Br2(g) is 0.190 Ms−1 at 150 ∘C. The rate of reaction is
nydimaria [60]

Answer:

Rate of reaction is 0.0950M.s^{-1}

Explanation:

  • Applying law of mass action for this reaction: rate=-\frac{1}{2}\frac{\Delta [HBr]}{\Delta t}=\frac{\Delta [H_{2}]}{\Delta t}=\frac{\Delta [Br_{2}]}{\Delta t}
  • -\frac{\Delta [HBr]}{\Delta t} represents rate of disappearance of HBr, \frac{\Delta [H_{2}]}{\Delta t} represents rate of appearance of H_{2} and \frac{\Delta [Br_{2}]}{\Delta t} represents rate of appearance of Br_{2}
  • Here, -\frac{\Delta [HBr]}{\Delta t}=0.190M.s^{-1}
  • So, rate of reaction = \frac{1}{2}\times (0.190M.s^{-1})=0.0950M.s^{-1}

How many valence electrons are in a molecule of phosphoric
Zanzabum

The number of valence electrons for each molecule or ion is shown beneath the structure. Remember hydrogen will not have more than two electrons. This hydrogen is part of a covalent bond (sharing two electrons). A double bond here would cause hydrogen to share four electrons with phosphorus.

Naddik [55]

Answer:

i think this is the answer you can try it tho...

Explanation:

Notice that the value 12.01 grams of natural carbon is the same as the atomic mass value (12.01 amu). It also tells us that 26.98 grams of aluminum contains exactly 6.022 x 1023 atoms of aluminum.
