Answer:

The balanced chemical reaction is written as follows:

bacl2 + na2so4 → baso4 + 2nacl

Therefore, the number of chlorine atoms in the reactants side and the products side would be 2 atoms in both sides which should be the case because the number of atoms in each side should have the same number.

Determine the empirical formula of a compound containing 48.38 grams of carbon, 8.12 grams of hydrogen, and 53.5 grams of oxygen
gogolik [260]

Answer:

Empirical formula = CH2O

Molecular formula = C6H12O6

Explanation:

According to this question, a compound is said to contain the following: 48.38g Carbon, 8.12g H, and 53.5g O.

First, we divide each mass value by its molar mass to convert to a mole value;

C = 48.38g ÷ 12g/mol = 4.03mol

H = 8.12g ÷ 1g/mol = 8.12mol

O = 53.5g ÷ 16g/mol = 3.34mol

Next, we divide each mole value by the lowest value (3.34mol)

C = 4.03mol ÷ 3.34 = 1.21

H = 8.12mol ÷ 3.34 = 2.43

O = 3.34mol ÷ 3.34 = 1

Approximately, the empirical ratio of CHO = 1:2:1, hence, the empirical formula is CH2O.

2. If the molar mass of the compound was determined to be 180.15 g/mol.

C = 12, H = 1, O = 16

(CH2O)n = 180.15

{12 + 1(2) + 16}n = 180.15

(12 + 2 + 16)n = 180.15

(30)n = 180.15

n = 180.15 ÷ 30

n = 6.005

Hence, (CH2O)n = (CH2O)6

Molecular formula = C6H12O6

All the processes that form mountain ranges are known as?
laiz [17]
All the processes that form mountain ranges are known as orogenesis. It is a process where a section of the Earth's lithosphere folds and deforms by compression forming mountain ranges this is due to movements of the tectonic plates. The forces or events that acts to this process are called oregony.

Match the era on the left with its characteristic on the right.
Troyanec [42]

Answer:

Mesozoic - the era before the current one

Cenozoic - the current era

Paleozoic - when life first flourished

Precambrian - the first era

Explanation:

The Precambrian is the earliest part of Earth's history, the first era. It's named like this because it preceded the Cambrian - the first period of the Phanerozoic eon, which is the current geologic eon. It lasted from the beginning of Earth (about 4.6 billion years ago) to the beginning of the Cambrian Period (about 541 million years ago).

Paleozoic is an era that lasted from about 541 to about 252 million years ago. During this time, life began to flourish.

Mesozoic is an era that lasted from about 252 to 65 million years ago. It's the era that took place before the current one - the Cenozoic.
