What is the molarity of a solution prepared by dissolving 10.0 grams of NaOH in enough water to make a solution with a total vol
riadik2000 [5.3K]

Solution :

Molecular mass of NaOH is 23 g/mol .

So, number of moles of NaOH is given by :

n = \dfrac{10}{40}\ mole

Now, we know molarity is given by :

Molarity = \dfrac{Number \ of \  moles\ of \ salute}{Volume ( in \  Liter ) }

M = \dfrac{10}{40\times 2.4} \  M\\\\M = 0.104 \ M

Hence, this is the required solution.

A nuclear power plant produces huge amount of electricity. However, it dumps radioactive wastes into the sea. This has led to an
TEA [102]

Answer: Provide the nuclear power plant with a plan to properly dispose of and recycle the wastes.

Explanation:

The nuclear power plant is producing huge amounts of electricity which is beneficial to the economy as it pushes growth. Shutting it down or relocating it is therefore not the right solution.

The problem is the radioactive waste being produced so a solution that is specific to this problem should suffice. That solution would be the provision of the nuclear plant with plans to properly dispose of the waste.

Should this happen, the nuclear plant can still stay in the same area and keep contributing to economic growth without adversely affecting people's heath.

which statement describes all chemical changes but not all physical changes a bubbles are produced b a new substance forms c pha
kirill [66]

The correct answer is:

B; A new substance forms.

Explanation:

A physical change, such as a state change or dissolving, does not produce a new substance, but an abundant change does. In a chemical reaction, the atoms and molecules that connect with each other are described as reactants. Chemical reactions happen when chemical bonds are broken and formed. If the molecules in a substance crash into each other with enough energy, some of the bonds in the molecules can break. The atoms can make new bonds with different atoms. A new substance forms.
