Cellular respiration is the reverse of photosynthesis because it is glucose + oxygen yield carbon dioxide water and ATP while photosynthesis is carbon + water yields oxygen and glucose. Cellular respiration is the way cells gain energy from the sun. Photosynthesis is the plants way of producing energy and these processes are basically the reverse of the other .

A public School district furnishes pencils to its elementary school. The pencils the secretary orders from the district warehous
const2013 [10]

Answer:

The minimum number of boxes of pencils to be ordered is 630 boxes.

Explanation:

Since a pupil uses averagely 9.3 pencils

and a box contains 12 pencils,

the school enrollment is also 812

school's enrollment x average use of pencil per student

__________________________________________

            number of pencils in a box

812 x 9.3 = 7551.6

7551.6 /12 = 629.3

Having a total number of 630 boxes of pencils to be ordered.

Which of the following are diatomic elements? CHECK ALL THAT APPLY!
Komok [63]

Answer: This is a list of the seven diatomic elements. The seven diatomic elements are:

   Hydrogen (H2)

   Nitrogen (N2)

   Oxygen (O2)

   Fluorine (F2)

   Chlorine (Cl2)

   Iodine (I2)

   Bromine (Br2)

All of these elements are nonmetals, since the halogens are a special type of nonmetallic element. Bromine is a liquid at room temperature, while the other elements all gases under ordinary conditions. As the temperature is lowered or pressure is increased, the other elements become diatomic liquids.

Astatine (atomic number 85, symbol At) and tennessine (atomic number 117, symbol Ts) are also in the halogen group and may form diatomic molecules. However, some scientists predict tennessine may behave more like a noble gas.

While only these seven elements routinely form diatomic molecules, other elements can form them. However, diatomic molecules formed by other elements are not very stable, so their bonds are easily broken.

How to Remember the Diatomic Elements

The elements ending with "-gen" including halogens form diatomic molecules. An easy-to-remember mnemonic for the diatomic elements is: Have No Fear Of Ice Cold Beer

Explanation:

SORRY if you don't understand!

using the equation, c5h12 8o2 arrow 5co2 6h2o, if 108 g of water are produced, how many grams of oxygen were consumed?
vfiekz [6]
Molar mass:

H₂O = 18.0 g/mol

O₂ = 32.0 g/mol

C₅H₁₂ + 8 O₂ -> 5 CO₂ + 6 H₂<span>O
</span>
8 x (32 g )<span> ------------ 6 x (18 g )</span>
mass O₂ ------------ 108 g H₂O

mass O₂ = 108 x 8 x 32 / 6 x 18

mass O₂ = 27648 / 108

mass O₂ =<span> 256 g</span>

<span>hope this helps!</span>

How do you solve this
denpristay [2]

Answer:

Explanation:

You simply have to multiply it by the molar mass =

m = 50mol SnSO4 x 214.773 g/mol

m = 10.738 g SnSO4

How are ionic bonds formed and what is the attractive force within an ionic bond
Akimi4 [234]

Answer and Explanation:

<u><em>How are ionic bonds formed?</em></u>

  • Ionic bonds are formed as a result of a redox reaction.
  • <em>Formation of cations:</em> In which atoms of an element (metal) with low ionization energy give some electrons to reach stable electronic configuration.
  • <em>Formation of anions:</em> in which atoms of another element with high electron affinity accepts electrons to achieve  a stable electronic configuration.
  • <em>Example: NaCl</em>, the sodium atoms loss electron forming Na⁺ and the chlorine atoms gain electron forming Cl⁻, then the ions are attracted to each other with 1:1 ration forming the ionic compound NaCl.

Na + Cl → Na⁺ + Cl⁻ → NaCl

<u><em>What is the attractive force within the ionic bond?</em></u>

  • The attractive force within the ionic bond is the electrostatic attraction between the positively charged ions (cations, Na⁺) and the negatively charged ions (anions, Cl⁻).
