Physics
1 answer:
liq [111]3 years ago
5 0

D. NaOH + HCI NaCl + H,0

Explanation:

The last option is a double displacement/replacement reaction.

This reaction is a neutralization reaction in which an acid combines with a base to produce salt and water only.

       NaOH    +   HCl   →   NaCl  + H₂O

  • A double displacement reaction is one that occurs between ionic compounds.
  • In this reaction, there is an actual exchange of reaction partners.

One of the following conditions serves as a driving force;

  • Formation of water or any other non-ionizing compound
  • Liberation of gases
  • Formation of a precipitate

Jonah is trying to move his 22-kg desk by pushing on it with a force of 130 N, but his brother is leaning on it with a downward
Dafna11 [192]

Answer:

0.54

Explanation:

Draw a free body diagram.  There are 5 forces on the desk:

Weight force mg pulling down

Applied force 24 N pushing down

Normal force Fn pushing up

Applied force 130 N pushing right

Friction force Fnμ pushing left

Sum of the forces in the y direction:

∑F = ma

Fn − mg − 24 = 0

Fn = mg + 24

Fn = (22)(9.8) + 24

Fn = 240

Sum of the forces in the x direction:

∑F = ma

130 − Fnμ = 0

Fnμ = 130

μ = 130 / Fn

μ = 130 / 240

μ = 0.54

olasank [31]

Answer:

the ability of data to be duplicated well described reproducibility

Explanation:

Reproducibitity of a data is the ability of a data to be produced in multiple times using the same procedure. It is used to test how precise a data is and it's usually known as standard deviation

Reproducibility is the closeness of the understanding between the consequences of measurements of the equivalent measurand did with a similar procedure depicted in the relating logical proof (for example a distribution in a companion surveyed diary).
