Explanation:

A compound is defined as the substance which contains different type of elements that are chemically combined together in a fixed ratio by mass.

Therefore, considering the letters in the word chemistry, name of different compounds will be as follows.

From C - Copper chloride.

From H - Hydrogen peroxide

From E - Europium(III) oxide

From M - Magnesium sulfate

From I - Iodine bromide

From S - Sulfur dioxide

From T - Titanium(IV) oxide

From R - Rhodium(III) chloride

From Y - Ytterbium(III) fluoride

Answer:

The second one

Explanation:

Gas pressure is caused by gas molecules bouncing off the container walls and each other. Every time a molecule changes direction because it hits a wall, the change in momentum results in a small push. Due to the large number of molecules involved, the pushes add up to a large amount of pressure.

How many moles of glucose can be produced

Arturiano [62]

Answer:

moles of glucose

<u>2.3166 moles of glucose</u>

<u></u>

Explanation:

The balance reaction for the formation of glucose is :

$6CO_{2}+6H_{2}O\rightarrow C_{6}H_{12}O_{6}+6O_{2}$

here , CO2 = carbon dioxide

H2O = water

C6H12O6 = glucose

O2 = Oxygen

According to this equation :

6 mole of CO2 = 6 mole of H2O = 1 mole of C6H12O6 = 6 mole of O2

We are asked to calculate the mole of Glucose from carbon dioxide.

So,

6 mole of CO2 produce = 1 mole of C6H12O6

1 mole of CO2 will produce =

$\frac{1}{6}$ moles of glucose

13.9 moles of CO2 will produce :

$\frac{1}{6}\times 13.9$

=2.3166 moles of glucose

Note : first , Always calculate for one mole (By dividing)

. After this , multiply the answer with the moles given.

Always write the substance whose amount is asked(glucose) to the right hand side

What’s Nacl molar mass amount

Likurg_2 [28]

NaCl is made of Na and Cl

The molar mass of Na = 22.989 g/mol

The molar mass of Cl = 35.453 g/mol

Molar mass of NaCl = 22.989 + 35.453

= 58.44 g/mol
