The following chemical equation describes the chemical reaction of hydrogen gas and oxygen gas to create water 2h2 + o2 = 2h2o use what you know about molar relationships to explain how scientists can predict the amount of water produced if they know the amounts of hydrogen and oxygen gases they have to react.

The study of chemicals and bonds is called chemistry. There are different types of elements, and these are metals and nonmetals.

The correct answer is 36 mole

According to the question, the 2 moles of water react with the mass of water:-

.

Hence, 36 g is used to react with hydrogen and oxygen.

For more information about the moles, refer to the link:-

The molar relationship says that every 1 mole of an element or compound weighs equal to its molecular weight.

As 1 mole of molecular hydrogen weighs 2 g.

2 moles of molecular hydrogen will weigh

1 mole of molecular oxygen weighs 32 g

1 mole of water weighs = 18g

2 moles of water weigh=

As can be seen from the balanced chemical equation above, 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water.

Thus 4g of combines with 32 g of to give 36 moles of .

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
