Why does electronegativity increase across a period?

Electronnegativity increase because the number of charges on the nucleus increases. Which attracts the bonding amount of electrons more.

The greater the friction, or rubbing, between particles in any fluid, the higher the viscosity. A fluid with a high viscosity has a large amount of internal friction. As the temperature of a gas increases, friction increases, and so the viscosity of the gas increases. The warmer the gas, the slower it flows.

A sample of a given compound contains 13.18g of carbon and 3.32g of hydrogen. What is the percent composition of the compound?

GarryVolchara [31]

The percent composition of the compound is 79.87 % of carbon and 20.12% of hydrogen

Explanation:

Given:

mass of carbon = 13.18 grams

mass of hydrogen = 3.32 grams

percent composition of compound =?

From the given data total mass of the compound is calculated

13.8 + 3.32

= 16.5 grams

The individual percentage of hydrogen and carbon will be calculated as:

percent composition = $\frac{individual mass of the element}{total mass of the compound}$ x 100

For carbon,

$\frac{13.18}{16.5}$ x 100

percent composition of carbon = 79.87 % of carbon.

for hydrogen:

$\frac{3.32}{16.5}$

= 20.12 % of hydrogen

In the compound given 79.87 % of carbon and 20.12% of hydrogen is present.
