Continents are generally the largest landforms on Earth. The Eurasian continent, a combination of Europe and Asia (since they are in contact for thousands of miles along the Ural Mountains) is by far the largest landform. Even without including Europe, Asia is the largest of the individual continents.
Hope this helped.

Why are carcinogens a concern to people?

Anarel [89]

Answer:

They have been found to cause cancer in humans meaning any release of carcinogens will increase, not decrease, CANCER RISK.

Explanation:

Certain chemicals, including benzene, beryllium, asbestos, vinyl chloride, and arsenic are known human carcinogens, meaning “they have been found to cause cancer in humans.” A persons risk of developing cancer depends on how much, how long, how often, and when they are exposed to these chemicals.

What is the mass (in mg) of 2.63 moles of nickel?

zaharov [31]

Data:
Molar Mass of Nickel = 58,7 g/mol

Solving:
58,7 g → 1 mol
y -------→ 2.63 mol

Solving: (They are proportional measures, the rule of three is made (directly proportional)

$\frac{58.7}{y} = \frac{1}{2.63}$
multiply cross
$1*y = 58.7*2.63$
$y = 154.381\:g \stackrel{converting}{\longrightarrow}\:\boxed{y = 154381\:mg}$

How many atoms of titanium are there in 0.125 mole of each of the following?a. ilmenite, FeTiO3b. titanium(IV) chloridec. Ti2O3d

Gekata [30.6K]

Answer:

a. 7.528x10²² atoms Ti

b. 7.528x10²² atoms Ti

c. 1.5055x10²³ atoms Ti

d. 2.258x10²³ atoms Ti

Explanation:

Using the molecular formula of the structures, we can determine the moles of titanium in 0.125 moles of each compound. With moles of titanium we can convert these to atoms using Avogadro's number as follows:

a. FeTiO₃: 1 mole of Ti per mole of FeTiO₃.

Moles of Ti are 0.125 moles. Atoms are:

0.125 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>7.528x10²² atoms Ti</h3>

b. Titanium (IV) chloride = TiCl₄: 1 mole of Ti per mole of TiCl₄.

Moles of Ti are 0.125 moles. Atoms are:

0.125 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>7.528x10²² atoms Ti</h3>

c. Ti₂O₃: 2 moles of Ti per mole of Ti₂O₃.

Moles of Ti are 2*0.125 moles = 0.25 moles. Atoms are:

0.25 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>1.5055x10²³ atoms Ti</h3>

a. Ti₃O₅: 3 mole of Ti per mole of Ti₃O₅.

Moles of Ti are 3*0.125 moles = 0.375 moles of Ti. Atoms are:

0.375 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>2.258x10²³ atoms Ti</h3>
