nirvana33 [79]3 years ago
8 0

Answer:Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

How do you count the number of elements in a compound?
kotegsom [21]

Answer:

The number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

A compound is a substance that is a mixture of more than one elements.

Compounds are made of two or more elements. These elements are represented by their symbols. These symbols can be identified and the number of elements represented by these symbols are counted.

For example, in the compound H_2OH

2

O :

H represents Hydrogen

O represents Oxygen

The elements in Water ( H_2OH

2

O ) are Hydrogen and Oxygen

Therefore, the number of elements in H_2OH

2

O is 2

Also in, NaClNaCl

The elements are Sodium(Na) and Chlorine(Cl)

There are two elements in NaCl

Hence, the number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

The Henry's Law constant (kH) for carbon monoxide in water at 25°C is 9.71×10-4 mol/L·atm. How many grams of CO will dissolve in
Olegator [25]

Answer: 0.0748 grams of CO will dissolve in 1.00 L of water if the partial pressure of CO is 2.75 atm

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{CO}=K_H\times p_{liquid}

where,

K_H = Henry's constant = 9.71\times 10^{-4}mol/L.atm

p_{CO} = partial pressure of CO = 2.75 atm

Putting values in above equation, we get:

C_{CO}=9.71\times 10^{-4}mol/L.atm\times 2.75atm\\\\C_{CO}=2.67\times 10^{-3}mol/L

C_{CO}=2.67\times 10^{-3}mol/L\times 28g/mol=0.0748g/L

Hence, the solubility of carbon monoxide gas is 0.0748 g/L
