Since there are no options, I'm gonna take a guess and say your answer is Metal.

"Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat." (Source: https://www.edinformatics.com/math_science/how-is-heat-transferred.html)

Conditions inside lysosomes have been shown to be acidic. These conditions are maintained by the lysosome membrane thus providing favorable conditions.

Specifically, ribosomes bind to messenger RNA, abbreviated mRNA. The ribosome reads a series of nucleotide bases in groups of three called codons.

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces

Brilliant_brown [7]

Answer:

0.364

Explanation:

Let's do an equilibrium chart for the reaction of combustion of ammonia:

2NH₃(g) + (3/2)O₂(g) ⇄ N₂(g) + 3H₂O(g)

4.8atm 1.9atm 0 0 Initial

-2x -(3/2)x +x +3x Reacts (stoichiometry is 2:3/2:1:3)

4.8-2x 1.9-(3/2)x x 3x Equilibrium

At equilibrium the velocity of formation of the products is equal to the velocity of the formation of the reactants, thus the partial pressures remain constant.

If pN₂ = 0.63 atm, x = 0.63 atm, thus, at equilibrium

pNH₃ = 4.8 - 2*0.63 = 3.54 atm

pO₂ = 1.9 -(3/2)*0.63 = 0.955 atm

pH₂O = 3*0.63 = 1.89 atm

The pressure equilibrium constant (Kp) is calculated with the partial pressure of the gases substances:

Kp = [(pN₂)*(pH₂O)³]/[(pNH₃)²* $(pO_2)^{3/2}$ ]

Kp = [0.63*(1.89)³]/[(3.54)²* $(0.955)^{3/2}$ ]

Kp = 4.2533/11.6953

Kp = 0.364

NaHCO3+HCI--->NaCI+H2O+CO2

evablogger [386]

Answer:

Explanation:

percent yield is ratio of actual yield or experimental yield divided by theoretical yield multiplied by 100 .

percent yield of 93.4 % means , the actual yield is 93.4 % what was expected from the reaction on the basis of given chemical reaction .

If in the experimental process , some sodium hydrogen carbonate is left unreacted due to absence of reactant HCl which is also required to obtain product , the percent yield will be increased if the required HCl is also provided .

Hence the percent yield will be increased if required HCl is made available .

A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical

Vaselesa [24]

<h2>A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical energy. nuclear energy.</h2><h2>ans: electromagnetic energy, thermal energy, solar energy, and mechanical energy.</h2>

Explanation:

Wind mill

It consist of shaft pole and blades that can rotate .

It converts wind energy into electrical energy .

The shaft of wind mill is connected to shaft of armature of generator .

When the fast moving wind rotates the blades of windmill its shaft rotates, armature rotates hence electricity is produced which is further used for various purposes .

Advantage of using wing energy

it is natural renewable resource

It is eco friendly

Disadvantage :

1. It cant be established everywhere

2. It requires large area

3. It is an expensive project

4. Wind dosen't blow all the time so win energy cant be produced every time

5. Minimum speed of wind required is 15km per hour .

So, the wind turbine generating electricity involves mechanical energy of wing and blades .
