Answer: <u>A integer is a whole number.</u>

<em>An adult with the flu has a temperature of 102°F</em>

<em>A brain contains  neurons (moving the decimal point to the right side power of 10 increases........here decimal point is moved to two places to the right side so power of 10 decreases from 10 to 8)</em>

<em>The time for a nerve impulse to travel from the feet to the brain is  s. (moving the decimal point to the right side power of 10 increases........here decimal point is moved to two places to the right side so power of 10 decreases from 0 to -2)</em>

What's the molar mass of Li3p
spayn [35]

Answer:

51.79g Li₃P.

Explanation:

Li has a molar mass of 6.94 g (since there are 3, you multiply it 3 times) and P has a molar mass of 30.97 g. 6.94(3) + 30.97 = 51.79g.

Yield for this reaction?<br> Reaction: N2(g) + 3 H2(g) → 2 NH3 (g)
andriy [413]

Answer:

Yes, yield.

Explanation:

N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation

First, find limiting reactant:  

Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2

Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2

The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)

Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3

What is the pH if the [H+] concentration is 3 x10^-13​
Shkiper50 [21]

Answer:

pH = 12.52

Explanation:

Given that,

The [H+] concentration is 3\times 10^{-13}.

We need to find its pH.

We know that, the definition of pH is as follows :

pH=-log[H^+]

Put all the values,

pH=-log[3\times 10^{-13}]\\\\pH=12.52

So, the pH is 12.52.
