Which of these rules is applicable to subtracting two values that have different numbers of decimal places (for example, subtrac

ting 2.1 from 2.15)? The answer is less accurate than either value. The answer is more precise than either value. The answer has the same number of decimal places as the least precise value. The answer has the same number of significant figures as the most precise value.

Which of the following compounds would you expect to be the most reactive?
9966 [12]

  The   compound  that  would  be   most   reactive  is   Ethyne  (answer A)


   <u><em>  explanation</em></u>

  •    Ethyne   is the  most    unsaturated  among the four  compounds  ( <em> it  has a triple bond between  the two carbon atoms) .</em>

  • The  triple  bond in ethyne   is made up  of 1  sigma  bond  and  2π   bond.
  • <em>The 2π  bond  are  weaker   and can  easily break   which  make  Ethyne  more  reactive than  Ethene, methane  and Ethane.</em>

A Sample Of Oxygen Gas Is Collected Over Water At 22°C And 98.67 KPa Pressure. If The Partial Pressure Of The Water Is 2.67 KPa,
Gwar [14]

Answer:

  • <em>The partial pressure of the oxygen gas is </em><u>96.00 KPa</u>

Explanation:

The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.

So:

  • Total pressure = ∑ individual pressures

  • Total pressure = Partial pressure of the water + Partial pressure of oxygen

  • 98.67 KPa = 2.67 KPa + Partial pressure of oxygen

  • Partial pressure of oxygen = 98.67 KPa - 2.67 KPa

  • Partial pressure of oxygen = 96.00 KPa ← answer

when the following redoc reaction is balances (assume acidic solution), how many moles of water appear and on what side
PolarNik [594]

8 moles of water on the right side.

An oxidation-reduction or redox reaction is a reaction that involves the transfer of electrons between chemical items (the atoms, ions, or molecules involved in the reaction).

Redox reactions: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.

Step 1:

MnO4- ----> Mn2+

2Cl- ------> Cl2

Step 2:

MnO4- --> Mn2+ + 4H2O

2Cl- -----> Cl2

Step 3:

8H+ + MnO4- ------> Mn2+ + 4H2O

2Cl- ----->Cl2

Step 4:

8H+ + MnO4- +5e- ------>Mn2+ + 4H2O

2Cl- ----> Cl2+ 2e-

Step 5:

16 H+ +2 MnO4- +10Cl- ----->2 Mn2+ + 8H2O+5Cl2

This is the balanced equation in an acidic medium.

That is 8, right side.

Wat are the five assumption of kinetic therory of gases​
il63 [147K]

Answer:

The five assumption of Kinetic molecular theory are given below.

Explanation:

Kinetic molecular theory of gasses stated that,

1) Gases consist of large number of smaller particles which are distance apart from each others.

2) The gas molecules collide with each other and also with wall of container and this collision is elastic.

3) Gas molecules are in continuous random motion and posses kinetic energy.

4) The forces of attraction between gas molecules are very small and considered negligible.

5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
