It would had to have melted in order to change the properties from a solid into a liquid. It also depends on the type of solid wheither a chemical or a ice cube. If it was a ice cube if would dilutte the liquid solution and changes the taste ot texture (feel) if it was a chemical the properties could change the liquid into a solid only depending on th type of chemical. EX..Liquid Nitrogen and a piece of raw chiken the outcome after putting the chicken in the nitrogen would be frozen. Because the chemical Nitrogen freezes the particles which makes the chicken frozen.

A 365 L balloon is blown up inside at 283 K. It is then taken outside in the hot sun and Heated to 300K. What is the new volume?

asambeis [7]

V₁ = initial Volume of the balloon after it is blown up = 365 L

V₂ = new Volume of the balloon after it is taken outside = ?

T₁ = initial temperature of the balloon = 283 K

T₂ = new temperature of the balloon = 300 K

using the equation

V₁/V₂ = T₁/T₂

365/V₂ = 283/300

V₂ = 387 L

What is the number of the group that has the most reactive nonmetals (give number and letter- Ex 1A, 2A, etc.)?

Kryger [21]

Answer:

Group 7A

Explanation:

The group 7A elements consists of the most reactive non-metals on the periodic table.

This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.

The elements in this group have the highest electronegativity values.
They have 7 valence electrons and requires just one electron to complete their octets.
This way, they are highly reactive in their search for that single electron.

What is the product of the reaction between HCIO3 and KOH

NISA [10]

Answer:

The products are: KCl03 and H20.

Explanation:

The reaction between HC03 (chloric acid) and KOH (potassium hydroxide) is:

HC03 + KOH ----> KCl03 (KCl03 and H20) + H20 (water)

The reaction is of the double displacement type (in this case parts of the reagents are exchanged, producing two generating new compounds).

A standard solution is prepared for the analysis of fluoxymesterone (c20h29fo3; 336 g/mol), an anabolic steroid. a stock solutio

-Dominant- [34]

Answer:

The concentration of new solution will be 1×10∧-7 M.

Solution:

Data Given

given mass of fluoxymesterone =16.8mg = 0.0168 g

molar mass of fluoxymesterone = 336g/mol

vol. of fluoxymesterone = 500.0 ml = 0.500 L

Stock Molarity of fluoxymesterone = (0.0168/336)÷0.500 = 1×10∧-4 M

So applying dilution formula

Stock Solution : New Solution

M1.V1 = M2.V2

( 1×10∧-4 M) × (1×10∧-6 L) = M2 × 0.001 L

[( 1×10∧-4) × (1×10∧-6)]÷[0.001] = M2

1 × 10∧-7 = M2

Result:

The concentration of new solution M2 will be 1 × 10∧-7
