2C6H6 + 1502 →12CO2 + 6H20

Chemistry
1 answer:
solmaris [256]1 year ago
5 0

Answer:

.926 moles

Explanation:

Rounding :

H2 0 = 18 gm/mole

   50 gm would then be   50 / 18 = 2.7777 moles of water

every two moles of 2 C6H6   produces   6 moles of water

   2.7777/6  * 2 = .926 moles

Which option accurately describes the first two stages of photosynthesis?
Lemur [1.5K]

Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.

How many Grams of NO is produced if 12g of O2 is combined with excess ammonia?
stich3 [128]

Answer:

9g

Explanation:

moles O2 = mass / Mr = 12 / 2(16.0) = 0.375

ratio O2 : NO = 5:4

moles NO produced = 0.375 * 4/5 = 0.3

mass NO = Mr * mol = (14.0+16.0) * 0.3 = 9g

How much calcium can be recovered from 75.0g of calcium fluoride
7nadin3 [17]

38.46g

Explanation:

Given parameters:

Mass of CaF₂ = 75.0g

Unknown:

Mass of calcium that can be recovered = ?

Solution:

This is a mass percentage problem and we need to solve it accordingly.

To solve this problem;

Find the molar mass of  CaF₂

Find the ratio between the molar mass of Ca and that of  CaF₂

Multiply by the given mass

Molar mass of  CaF₂ = 40 + (2 x 19) = 78g/mol

Mass of calcium = \frac{40}{78} x 75 = 38.46g
