The volume of the liquid = 8.7 ml

<h3>Further explanation</h3>

Graduated cylinder is a laboratory tool used to measure the volume of liquid

Also called a measuring cylinder

Each line (marked line) on this cylinder shows a scale that shows the total volume of water.

The reading is based on a curve of the fluid formed called the meniscus. Read the measurement of the amount of fluid at the bottom of the meniscus (the position of our eyes is parallel to the level of the meniscus and the cylinder is located in a flat (not tilted) place

If we look at the picture (attached), the meniscus is located between the scale / line 8.6 and 8.8(interval 0.2 ml), so the volume of the liquid shows the number 8.7 ml

How many miles of lead are equal to 9.51 x 10^3 g Pb?

Lemur [1.5K]

Molar mass Pb = 207.2 g/mol

1 mole Pb ------------- 207.2
? mole Pb ------------ 9.51 x 10³

moles = 9.51 x 10³ * 1 / 207.2

moles = 9.51 x 10³ / 207.2

= 45.89 moles

hope this helps!

7. Diethyl ether burns in air according to the following equation. C4H10O(l) + 6O2 (g) → 4CO2 (g) + 5H2O(l) If 7.15 L of CO2 is

iren [92.7K]

From the stoichiometry of the combustion reaction, we can see that 7.4 L of oxygen is consumed.

<h3>What is combustion?</h3>

Combustion is a reaction in which a substance is burnt in oxygen. The equation of the reaction is; C4H10O(l) + 6O2 (g) → 4CO2 (g) + 5H2O(l)

We can obtain the number of moles of CO2 from;

PV = nRT

n = 1.02 atm * 7.15 L/0.082 atm LK-1mol-1 * (125 + 273) K

n = 7.29 /32.6

n = 0.22 moles

If 6 moles of oxygen produces 4 moles of CO2

x moles of oxygen produces 0.22 moles of CO2

x = 0.33 moles

1 mole of oxygen occupies 22.4 L

0.33 moles of oxygen occupies 0.33 moles * 22.4 L/ 1 mole

= 7.4 L of oxygen

Element A has 15 protons. Determine the number of neutrons in its isotope with mass number 33.

bagirrra123 [75]

In an electrically neuteral atom, number of protons = number of electrons = atomic number.
Mass number = neutrons + protons/electrons/atomic number
Therefore,
neutrons = mass number - <span>protons/electrons/atomic number
Neutrons = 33 - 15 = 18

The answer is thus B. But this is the solution and explanation along with it as proof.</span>
