it is A Acid

Explanation : Any substance that yields a hydrogen ion when placed in a water solution is called an acid. According to Arrhenius theory of Acids and Bases, Acids are those substances which on dissociation in solution generates ions. Whereas a Base is a substance that dissociates in the solution to produce ions.

What forms when iron-53 decays?

erastovalidia [21]

It depends on the type of decay that's taking place, but if it's b+ it'd decay into Mn-52. If it's b- it'd decay into Co-59 (i'm sure??)

**Find the speed of an object that travels 500 miles in 5 hours. S = d/t

irinina [24]

Answer:

I believe that would be 100 mph.

Explanation:

Your distance (d) is 500 miles and your time (t) is 5 hours.

So when you replace the variables with numbers you bet 500/5 which is 100.

Therefore, you speed (S) would be 100mph.

An unknown compound with a molar mass of 155.06 g/mol consists of 46.47% c, 7.80% h, and 45.72% cl. find the molecular formula f

Contact [7]

Answer:- Molecular formula of the compound is $C_6H_1_2Cl_2$ .

Solution:- From given information:

C = 46.47%

H = 7.80%

Cl = 45.72%

First of all we find out the empirical formula from given percentages. We divide the given percentages by their respective atomic masses to calculate the moles:

$C=\frac{46.47}{12.01}$ = 3.87

$H=\frac{7.80}{1.01}$ = 7.72

$Cl=\frac{45.72}{35.45}$ = 1.29

Now, we divide the moles of each by the least one of them. Least one is Cl as it's moles are least as compared to the moles of C and H. So, let's divide the moles of each by 1.29.

$C=\frac{3.87}{1.29}$ = 3
