\huge \bf༆ Answer ༄

The given masses are :

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:27.540 \: kg

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:24.350 \: kg

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:14.380 \:  kg

Now, add them all ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:27.540 + 24.350 + 14.380

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:66.270 \:  kg

<u>Answer:</u>

  • The sum of 27 kg 540 g, 24 kg 350 g, and 14 kg 380 g is 66 kg 270 g.

<u>Explanation:</u>

<u>First, let's convert all these weights into decimal.</u>

  • => 27 kg 540 g, 24 kg 350 g, 14 kg 380 g
  • => 27.540, 24.350, 14.380

<u>Next, let's add the decimals.</u>

  • => 27.540 + 24.350 + 14.380
  • => 51.890 + 14.380
  • => 66.270

<u>Lastly, let's convert the resulting decimal back to normal form.</u>

  • => 66.270
  • => 66 kg 270 g

Hence, <u>the sum of 27 kg 540 g, 24 kg 350 g, and 14 kg 380 g is 66 kg 270 g.</u>

Hoped this helped.

What are the Lewis definitions of an acid and a base? In what way are Bronsted definitions? they more general than the In terms
kati45 [8]

Explanation:

Lewis definition of Acids and Bases

Chemical species which are capable of accepting electron pairs or donating protons are called Lewis acid.

Chemical species which are capable of donating electron pairs or accepting protons are called Lewis base.

Bronsted definition of acids and bases

Chemical species which are capable of donating H+ are called Bronsted acids.

Chemical species which are capable of accepting H+ are called Bronsted bases.

So all Bronsted acids are Lewis acids but all Lewis acids are not Bronsted acids.

For a chemical species to behave as Lewis acid, they must have:

  • Incomplete octet
  • Double bond
  • Vacant d-orbitals

For example, in BF3, octet of boron is incomplete, so it can accept a pair of electron and behaves as Lewis acid.

For a chemical species to behave as Lewis base, they must have:

  • lone pair of electrons

For example, NH3 and OH, both N and O have lone pairs of electrons, hence behave as Lewis base.

What 3 things drive the pressure of a gas up
Sedaia [141]

Answer:

<h3>Density of the Gas</h3>

Explanation:

More molecules mean more hits against the container walls. Increasing the number of particles means you have increased the density of the gas. This third factor is part of the ideal gas law, which explains how these three factors -- temperature, volume and density -- interact with each other.

A first order reaction has a rate constant of 0. 543 at 25°C. Given that the activation energy is 75. 9 kj/mol. Calculate the ra
Rasek [7]

The rate constant of first order reaction at 32. 3 °C is 0.343 /s must be less the 0. 543 at 25°C.

First-order reactions are very commonplace. we have already encountered  examples of first-order reactions: the hydrolysis of aspirin and the reaction of t-butyl bromide with water to present t-butanol. every other reaction that famous obvious first-order kinetics is the hydrolysis of the anticancer drug cisplatin.

The value of ok suggests the equilibrium ratio of products to reactants. In an equilibrium combination both reactants and merchandise co-exist. big ok > 1 merchandise are k = 1 neither reactants nor products are desired.

Rate constant K₁  = 0. 543 /s

T₁  = 25°C

Activation energy Eₐ =  75. 9 k j/mol.

T₂ = 32. 3 °C.

K₂ =?

formula;

log K₂/K₁=  Eₐ /2.303 R [1/T₁ - 1/T₂]

putting the value in the equation  

K₂ = 0.343 /s

Hence, The rate constant of first order reaction at 32. 3 °C is 0.343 /s

The specific rate steady is the proportionality consistent touching on the fee of the reaction to the concentrations of reactants. The fee law and the specific charge consistent for any chemical reaction should be determined experimentally. The cost of the charge steady is temperature established.
