After examining a cell with a microscope, a student concludes that it is a plant cell.

Chemistry
1 answer:
Scorpion4ik [409]3 years ago
7 0

Explanation:

The student most likely observed both <u>(A) Vacuole</u> and <u>(C) Chloroplast</u> that led him to the conclusion, that the cell is a plan cell.

<u>Reason :</u>

In a plant cell, <u>Vacuole</u> occupies 70% to 90% of the total volume of the cell, making it easier to identify.

Chloroplast contains photosynthetic pigment called chlorophyll (green in colour), which is only found in plant cell.

Identify the substances that will appear in the equilibrium constant expression for the equation: 2Ag+(aq)+Zn(s)&lt;-&gt;Zn2+(aq
Simora [160]

Hey there!


We Know that:



 2 Ag⁺(aq) + Zn(s) <-> Zn²⁺(aq)+2 Ag(s)


The equilibrium expression for the reaction is:



Kc =  [ Zn⁺² ]  /  [Ag⁺ ]²


Hope that helps!

How much energy is required to raise the temperature of 10.7 grams of gaseous helium from 22.1 °C to 39.4 °C ?
Rainbow [258]

Answer:

Q = 2640.96 J

Explanation:

Given data:

Mass of He gas = 10.7 g

Initial temperature = 22.1°C

Final temperature = 39.4°C

Heat absorbed = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree. Specific heat capacity of He is 14.267 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 39.4°C - 22.1°C

ΔT = 17.3°C

Q = 10.7 g× 14.267 J/g.°C ×  17.3°C

Q = 2640.96 J

Using the Brønsted theory, classify the following as either an acid or a base by placing the compound in the correct bin.
guapka [62]

Answer : The Bronsted-Lowry theory was not against the Arrhenius theory, rather it was just a modification to the previous theory of acids and bases. Hydroxide ions are considered as bases because they have the tendency to accept hydrogen ions from acids and form water.

An acid was the one which produces hydrogen ions in solution because it reacts with the water molecules by giving a proton to them.

In a nutshell, he described bases as hydrogen acceptor and acids as hydrogen donors.
