Science is based primarily on peoples opinions and views of the subject matter.
kvv77 [185]

Answer:

False

Explanation:

Science is not based on primarily on peoples opinions and views of the subject matter whereas science is based on empirical observations and research for its validity.

<u>Science aims to find answers to human questions related to the natural world through their research observation and experiments. Scientists and researchers provide valid proof of human questions so that people can trust them.</u>

Science can change people's opinions regarding the natural world with valid proof and observational theories but science is not based on people's opinion.

Hence, the given statement is "false".

Compared with surface currents, deep currents are a. colder and less dense. c. warmer and denser. b. warmer and less dense. d. c
Katyanochek1 [597]

The correct answer is option d, that is, colder and denser.  

The surface currents refer to the currents at the surface of the water, to a few hundred meters deep, while deep currents refer to the currents when the density increases to a greater extent.  

The surface current takes place close to the surface and move horizontally. This kind of currents are caused by global winds, an example of surface current is Gulf Stream. On the other hand, deep current takes place in the ocean and is affected by the density of water, temperature, and salinity. An example is Antarctica Bottom Water. In comparison to surface currents, deep currents are colder and denser.

1. When an acid reacts with a base, what compounds are formed? (1 point) a salt only water only metal oxides only a salt and wat
scoundrel [369]

Answer: 1) only a salt and water

An acid and base reacts together to undergo neutralization to form salt and water.

HCl+NaOH\rightarrow NaCl+H_2O

where HCl is an acid and NaOH is a base to form salt (NaCl) and water (H_2O).

Answer: 2) The formula of the hydrogen ion is often written as H^+.

All acids dissociate in water to give  H^+ ions.

Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.

HCl\rightarrow H^++Cl^-

Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.

NaOH\rightarrow Na^++OH^-

Answer: 4) A conjugate acid base pair  transfers hydrogen ion.

CH_3COO^-+H_2O\rightarrow CH_3COOH+H_3O^+

Here CH_3COO^- accepts a proton and thus act as a base and the corresponding CH_3COOH is its conjugate acid.

Answer: 5) Bronsted Lowry acid is a substance that donates protons.  Bronsted Lowry base is a substance that accepts protons.

NH_4^+ and NH_3

NH_3+H^+\rightarrow NH_4^+

NH_3 is a acid which accepts proton and thus acts as base to form conjugate acid NH_4^+.
