Answer:
Explanation:
From the given information:
Let y(t) be the amount of sugar in tank A at any time.
Then, the rate of change of sugar in the tank is given by:

The rate of the sugar coming into the tank is 0


Initial amount of sugar = 25 Pounds
Now; y(0) = 25
25 = Ce⁰
C = 25
So; y(t) = 25 
Thus, the amount of sugar at any time t = 
B) For tank B :

I am not sure bout this question sry
Answer: There are 0.25 moles of NaOH in a sample that weighed 10g.
Explanation:
Given: Mass of NaOH = 10 g
Molar mass of NaOH is 40 g/mol.
Number of moles is the mass of substance divided by its molar mass.
Therefore, moles of NaOH are calculated as follows.

Thus, we can conclude that there are 0.25 moles of NaOH in a sample that weighed 10g.
There's three types of decay: alpha beta and gamma.
*
Alpha decay is the emission of a helium nucleus (2protons and 2 neutrons)
*
Beta decay is the emission of an electron or a positron (

or

). It does affect the weight of the atom.
*
Gamma decay is the emission of photons with a high energy. It does affect the weight of the atom.
To answer the question,
any nuclear reaction which decreases the atomic weight by 4 and the protons by 2 is an alpha decay. (release of an alpha or helium nucleus)
Answer:
the answer is c carbon dioxide and water
