The first order reaction A → B, has k = 2.10. If the initial concentration of reactant A is 1.500 M, how long will it take [A] =
Semenov [28]

Answer:

ln( \binom{at}{ao}{}  )  =  - kt

Explanation:

ln( \binom{0.6}{1.5} )  =  - 2.1t

ln(0.4)  =  - 2.1t

T = 0.436.

I used the formula for first order reaction.

I hope you get this.

Amanda [17]

Answer:A) It was developed from past observations- true

It is subject to experimentation and revision.- false

It explains why mass is conserved- false

It predicts future observations-true

Before a hypothesis is proclaimed to be a law in science, numerous observation must have confirmed its validity and rigorous experimentation under carefully controlled conditions usually precedes the acceptance of a hypothesis as a law. The law of conservation of mass was developed from numerous past observation that proved its validity.

Somebody help me with this please very much appreciated
Flauer [41]

The answer for the following answer is explained below.

The answer is NH_{4} ^{+}

Explanation:

Bronsted-Lowry acid :

It is a solution that donates protons, and is known as a proton donor.It donates protons in the form of hydrogen ion(H^{+}).This is reinforced by the definition of an acid ,which is a solution that has hydrogen ions.

In Bronsted-Lowry aci it must contain a hydrogen io that it can give up.When the acid gives a hydrogen ion,the charge of an acid decreases.

Here,

NH_{4} ^{+}  loses one hydrogen ion and forms ammonia molecule.

So therefore the Bronsted-Lowry acid  is NH_{4} ^{+}.
