What is the solution to the problem expressed to the correct number of significant figures?

Answers

Answer:

(102 900 ÷ 12) + (170 × 1.27) = 8800

Step 1. Evaluate the expressions inside the parentheses (PEMDAS)

102 900 ÷ 12 = 8575

170 × 1.27 = 215.9

In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

Thus, the underlined digits are not significant, but we keep them in our calculator to avoid roundoff error.

Step 2. Do the addition (PEMDAS).

  8575

+    215.9

= 8790.9

Everything that you add to an insignificant digit gives an insignificant digit as an answer.

Thus, the underlined digits are not significant.

We must drop them and round up the answer to 8800.

In a chemical reaction*
1 point
The atoms of the reactants unbond, rearrange, and then rebond to form the products
Some atoms disappear while others multiply to form the products
The atoms of the reactants always stay together to form the products
New atoms are formed which combine to make the products

Answers

Answer:

1st one is correct

The atom of the reactants unbound , rearrange, and then rebond to form the product

hope it helps

In a chemical reaction, the atoms of the reactants unbond, rearrange, and then rebond to form the products. Therefore, option A is correct.

What is chemical reaction ?

Chemical reaction, the transformation of one or more chemicals the reactants into one or more distinct compounds, the products. Chemical elements or chemical compounds make up substances.

Combustion reaction, decomposition reaction, neutralization reaction, redox reaction, precipitation or double-displacement reaction, and synthesis reaction are some of the numerous types of reactions.

In a chemical reaction, bonds between molecules of the reactant are broken and new bonds between molecules of the product are established to create a new substance.

A chemical equation is nothing more than a mathematical statement that represents how reactants form products.

Thus, option A is correct.

HELP PLEASE , ITS DUE BY 6 ❤️10. If temperature were increased at the same rate for all four substances, which substance
would turn into a gas first?

Answers

Answer:

Dependant

Explanation:

Depending on the kind of substance you have (since ur answer of what substances was vauge) you would want to look at the molecular structure of the substances.

Understanding intermolecular bonds are key here (research this)

For example, Bromine is found as Br2 and only exerts London dispersion forces as there is no difference in polarity. And because this force is weaker, it has a lower boiling point

Another example being something like Hydrochloric acid (HCl). This is where Hydrogen acts as the positive atom while chlorine is the negative atom. This creates a stronger force and thus, a higher boiling point than Br2

Finally, there is Something like H2O where the force in play is Hydrogen bonding as Nitrogen, Oxygen, Fluorine where the bonds are strongest due to the electronegativity is at the greatest difference between these and Hydrogen. and thus having a higher boiling point.

So depending on the substance's bond, that will help determine the boiling point. If they fall under the same group, go based on the greatest difference in electronegativity.

I don't know if this is what you're looking for but, hope this helps. :)

If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (show work)

Answers

Answer:

8.

Explanation:

Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.

If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.

16 - 8 = 8

why is respiration considered an exothermic process​

Answers

Answer:

Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.

Explanation:

1)Change the following temperatures to Kelvin: 100 C and -20 C
2)Change the following temperatures to Celsius: 273 K and 15 K

Answers

Answer:

373 K; 253 K

0°C ; -258°C

Explanation:

In order to change Temperatures to Absolute Value (Kelvin) you shoud do this sum:

T° in C  + 273 = T° in K

For question 1:

100°C + 273 = 373K

-20°C + 273 = 253K

For question 2:

T° K - 273 = T° C

273 K - 273 = 0°C

15 k + 273 = -258 °C
