The formula for Cs and S is Cs₂S.

For Cs and S,

Ions formed will be Cs⁺ and S²⁻

As cesium belongs to group 1A and sulfur belongs to group 6A. Therefore, the condensed electronic configuration is -

For Cs is [Xe} 6s¹ and for S is [Ne] 3s²3p⁴.

Cs have 1 valence electron and S have 6 valence electrons.

Hence to attain a stable electronic configuration, both two Cs atoms lose one electron and form Cs⁺ and these two electrons will be accepted by one S atom to form S²⁻.

Therefore the formula for the compound is Cs₂S as Cs donate 1 electron and S will accept 2 electrons from Cs.

The formula is Cs₂S.

Write E in the blank if the material is heterogeneous or O if it is homogeneous.
Advocard [28]

Answer/Explanation:

Wood: E

Freshly brewed black coffee: O

Water: O

Lucky Charms: E

Salt: O

Dirt: E

Sausage and mushroom pizza: E

Air: O

Milk: O

Gold: O

Any mixture that looks the same through the substance is homogenous. The different parts are unable to be visibly seen. (Any periodic element is homogenous)

Any mixture that can be easily determined a mix and cannot be evenly separated or dispersed is heterogenous.

Answer:

14.7838

Explanation:

Given that;

A student uses a solution that contains 16 g of water to conduct an experiment and at the end of an hour ; the amount have decreased by 3.5%

The mathematically illustration for this is given as

= 16 g ×  3.5%

= 16 *\frac{3.5}{100}

= 0.56  

After an hour; the amount have decreased by 16 - 0.56

= 15.44

after 2 hours the water decreased by another 4.25%

i.e  15.44 * \frac{ 4.25}{100}

⇒ 0.6562

after two hours , the amount would have decreased by:

= 15.44 - 0.6562

= 14.7838

Kay [80]

Answer: 18.0152 milliliters

Explanation:

Hi, to answer this question we have to apply the next formula:

Water volume = water mass / water density

Since 1 mol of water weights 18.0152 grams

Replacing with the values and solving:

Water volume = 18.0152 g / 1 g /ml = 18.0152 milliliters

Feel free to ask for more if needed or if you did not understand something.
