Answer:

D. The coefficients give the ratio of mole reactant to moles product.

Explanation:

In stoichiometric calculations, the amount of product formed from reactants can be determined.

Using this approach, the number of moles of reactants and products on both sides of the expression must be balanced.
As a rule of thumb, the coefficients give the ratio of moles of reactants to moles of products.
This is very useful in a number of calculations using the stoichiometric approach.

A student calculates that the volume of his textbook is 991.880 cm3. what is the volume written with 3 significant figures?

k0ka [10]

The volume of the textbook calculated by the student written to 3 significant figures is 992cm³

According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.

To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.

To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.

Select the correct answer from each drop-down menu. An atom has 9 electrons and 9 protons at the start. If it loses 2 electrons,

aalyn [17]

Answer:

If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.

Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.

C3H8 and CH4 are 2 compounds made from the same elements. This is an example of which law? A) Law of Conservation of Mass b) Law

Sphinxa [80]

C3H8 and CH4 are two compounds made from the same two elements, C and H. The ratios of C and H for both are round numbers.

Law of multiple proportions states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

So the ans is C) Law of Multiple Proportions
