Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.
tamaranim1 [39]

Answer:

1500kg/m^3

Explanation:

Formula:

d=m/v

Given:

m=1.5kg

v=1000cm^3

(The side length of a cube is always equal to the others)

Required:

d=?

Solution:

d=m/v

d=1.5kg/1000cm^3

d=1.5kg/0.001m^3

d=1500kg/m^3

Hope this helps ;) ❤❤❤

Match the specific enzyme to its class. A. oxidoreductase B. hydrolase C. transferase D. ligase E. lyase aminase
lilavasa [31]

Answer: Every enzyme has a specific name that can give us insight into the specific reaction that that enzyme can catalyze. We divide them into six different categories.

1) Oxidoreductase - includes two different types of reactions by transferring electrons from either molecule A to B or vice versa. It is involved in oxidizing electrons away from a molecule.

2) Hydrolase - uses water to divide a molecule into two other molecules.

3) Transferase - you move some functional group X from molecule B to molecule A

4) Ligase - catalyzes reactions between two molecules, A and B, that are combining to form a complex between the two. (example: DNA replication)

5) Lyase - divides a molecule into two other molecules without using water and without reducing or oxidation

MARKING BRAINLIEST!!!<br><br>Complete a combining ratio of Lithium and Oxygen.
cluponka [151]

Li₂O

Explanation:

Elements or ions exchange their combining powers or their simplest whole number ratio during the formation of a chemical formulae of compounds.  

  The combining power of lithium is 1

                                           Oxygen is 2

                                    Lithium                                       Oxygen

Combining

power                               1                                                  2

Exchange of

valencies                          2                                                  1

   

    Molecular formula of the compound gives Li₂O
