Answer:
There are 0.0305 calories in 0.128 joules
Explanation:
Given that,
Heat absorbed, Q = 0.128 J
We need to find the heat energy absorbed in calories.
We know that the relation between joules and calories is as follows :
1 calorie = 4.184 J
1 J = (1/4.184) J
So,
So, there are 0.0305 calories in 0.128 joules
Answer:
True
Explanation:
Table sugar and table salt are pure substances....When elements chemically combine, they form compounds that have properties that are similar to those of the uncombined elements.
i think the answer is C because it take a Molecular form so im certain the correct answer is c
From the calculations, we can see that the half life of the material is 11.4 days
<h3>What is radioactivity?</h3>
The term radioactivity refers to the spontaneous disintegration of a radioactive nucleus. The time taken for half of the radioactive material to remain.
Given that;
N/No = (1/2)^t/t1/2
N = amount that remained
No = amount that remained in the beginning
t = time taken
t1/2 = half life of the substance
N =Noe^-kt
4.995 ×10^9 = 1.75 x 10^12e^-55k
3.5* 10-2=e^-55k
k = ln3.5* 10-2/-55
k =0.06095
t1/2 = 0.693/0.06095
t1/2 = 11.4 days
