Answer:

Similarity between photosynthesis and cellular respiration is that both process :

<u>Involve production of energy </u>

<u>Exchange of gases</u>

<u>Goes through electron chain reactions</u>

<u></u>

Explanation:

<u>Photosynthesis</u> : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

<em><u>The electrons triggers the reaction of food formation</u></em>.

<em><u>Energy is released during photosynthesis.</u></em>

<em><u>Gaseous exchange between CO2 and O2 occur.</u></em>

<u>Respiration </u>:

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

<u><em>Exchange of Gases occur between organism and environment.</em></u>

<em><u>Here , mitochondrial electron transport occurs to produce ATP</u></em>.

Hence , similarity between photosynthesis and cellular respiration is that both process:

<u>Involve production of energy </u>

<u>Exchange of gases(carbon dioxide and oxygen)</u>

<u>Goes through electron chain reactions</u>

17) A 0.20 M solution of HCl with a volume of 15.0 mL is exactly neutralized by the 0.10 M solution of NaOH with what volume? HI
galina1969 [7]

Answer: A 0.20 M solution of HCl with a volume of 15.0 mL is exactly neutralized by the 0.10 M solution of NaOH with 3 mL volume.

Explanation:

Given: M_{1} = 0.20 M,      V_{1} = 15.0 mL

M_{2} = 0.10 M,            V_{2} = ?

Formula used is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula s follows.

M_{1}V_{1} = M_{2}V_{2}\\0.20 M ]times 15.0 mL = 0.10 M ]times V_{2}\\V_{2} = 30 mL

Thus, we can conclude that a 0.20 M solution of HCl with a volume of 15.0 mL is exactly neutralized by the 0.10 M solution of NaOH with 3 mL volume.

A sample of 28 Mg decays initially at a rate of 53500 disintegrations per minute, but the decay rate falls to 10980 disintegrati
prisoha [69]

Answer : The half life of 28-Mg in hours is, 6.94

Explanation :

First we have to calculate the rate constant.

Expression for rate law for first order kinetics is given by:

k=\frac{2.303}{t}\log\frac{a}{a-x}

where,

k = rate constant

t = time passed by the sample = 48.0 hr

a = initial amount of the reactant disintegrate = 53500

a - x = amount left after decay process disintegrate = 53500 - 10980 = 42520

Now put all the given values in above equation, we get

k=\frac{2.303}{48.0}\log\frac{53500}{42520}

k=9.98\times 10^{-2}hr^{-1}

Now we have to calculate the half-life.

k=\frac{0.693}{t_{1/2}}

9.98\times 10^{-2}=\frac{0.693}{t_{1/2}}

t_{1/2}=6.94hr

Therefore, the half life of 28-Mg in hours is, 6.94

Can someone plz explain ionic and covalent bonding plzzzz!!!
Alexeev081 [22]

Answer:

Ionic Bonding: The formation of an Ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal.

Covalent Bonding: Bonding between non-metals consists of two electrons shared between two atoms.
