Living organisms need energy to carry on their life processes. Photosynthesis is a process that allows for photosynthesizing org

anisms, such as algae and green plants, to produce their own materials for energy production and survival. This process can be outlined as a simplified chemical equation containing reactants (goes into the process) and products (made/comes out of the process).Using your knowledge of science and figures above, select the choice that accurately expresses photosynthesis.

the correct combo is C

We know sunlight is key factor in photosynthesis so A and D are out.

we also know plants get their bulk by breaking up co2 and using the carbon which releases oxygen as a byproduct so B is also out of the question.

Zinaida [17]

Answer:

2.9 g

Explanation:

There is some info missing. I think this is the original question.

<em>Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas, chlorine gas, oxygen gas, water, and a great deal of energy. </em>

<em>What mass of water is produced by the reaction of </em><em>9.6 g</em><em> of ammonium perchlorate?</em>

<em />

Step 1: Given data

Mass of ammonium perchlorate: 9.6 g

Step 2: Write the balanced equation

2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(l)

Step 3: Calculate the moles corresponding to 9.6 g of ammonium perchlorate

The molar mass of ammonium perchlorate is 117.49 g/mol.

9.6 g \times \frac{1mol}{117.49 g} = 0.082mol

Step 4: Calculate the moles of water formed from 0.082 moles of ammonium perchlorate

The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of water formed are 4/2 × 0.082 mol = 0.16 mol

Step 5: Calculate the mass corresponding to 0.16 moles of water

The molar mass of water is 18.02 g/mol.

0.16 mol \times \frac{18.02g}{mol} = 2.9 g

The number of atoms in 2.50 mol Cr
Slav-nsk [51]

Answer:

1.51 x 10²⁴atoms

Explanation:

Given parameters:

Number of moles of Cr = 2.50mol

Solution;

what is a mole;

  a mole of any substance is the amount of substance that contains the avogadro's number of particles which is 6.02 x 10²³ particles

The particles here can be atoms, protons, neutrons, electrons e.t.c

                   1 mole contains 6.02 x 10²³ atoms

                  2.5 moles will contain  2.5 x 6.02 x 10²³   = 1.51 x 10²⁴atoms

When a substance dissolves, it undergoes a _____.
Anastasy [175]

The right answer is physical change.

In the general sense, dissolution is the action of dissolving something, that is to say, of decomposing it by the separation of its parts.

In chemistry, dissolution is an intimate mixture of two bodies, at least one of which is liquid.

Eg: the dissolution of sugar in the water, the sugar will pass from the solid and dry state to the dissolved state so there is a physical change. The sugar is going to be surrounded by water molecules and form hydrogen bonds, so it can be a chemical change.
