Answer:

half life = 25 days

Explanation:

Given data:

Total amount of sample = 40 mg

Sample left after 50 days = 10 mg

Half life of P³³ = ?

Solution:

<em>1st step:</em>

when time is zero = 40 mg

1 half life = 40/2 = 20 mg

2 half life = 20/ 2= 10 mg

<em>2nd step:</em>

<em>Elapsed time/ half life = HL</em>

half life = 50 days/ 2

half life = 25 days

Consider the given acid ionization constants. identify the strongest conjugate base.
WARRIOR [948]
The question is incomplete. Complete question is:
<span>Consider the given acid ionization constants. identify the strongest conjugate base.
</span>HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option 4: HCN(aq) 4.9×10−10

Reason: 
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.

In present case, ionization constant is highest of HCN i.e. 4.9×10^{-10}. This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e. CN^{-}) is the weakest.

Type the correct answer in each box.
Arturiano [62]

Answer:

5SiO2 + 2CaC2 = 5Si + 2CaO + 4CO2

Explanation:

balancing equations is a lot of trial and error. My strategy to approaching this equation was to get the O's balanced. After trying several combonations I found that I needed 10 O's on each side of the equation for the other elements to match up. After I balanced the O's, I balanced my C's to 4 on each side. Then I balanced my Ca's to have 2 on each side. And last but not least I balanced my Si to have 5 on each side.
